More than a third of the students at North Berwick High have signed a petition challenging Christianity’s monopoly in Religious Observance and School Assemblies. In order to express their views more freely, they have set up their own newspaper, The Contender, of which the first two numbers are available on line here and here, and obtained a grant to pay for a print edition. These actions have attracted well-deserved media attention both locally and UK-wide, and are likely to be discussed by the Scottish Youth Parliament.
Here is what they’ve signed:
Petition for the Secularisation or Religious Diversity of School Assemblies and/or Functions
By signing this petition you, as a North Berwick student, are agreeing that there should either be no religious influence (in assemblies, other events) in school or that all religious denominations should be represented, and that it is inappropriate for only one religion (Christianity) to be advocated, in particular the assemblies led by members of the Christian church.
Setting up a newspaper of the quality achieved at North Berwick is a major enterprise, but these days any group of students can publish articles expressing its views using WordPress or Blogger, and spread word of them through social media. Moreover, any group of students in any school can organise a petition like this one, and, as we shall see, would be right to do so.
It is inappropriate for only one religion (Christianity) to be advocated, in particular the assemblies led by members of the Christian church.

Strange as it may seem, all the students are demanding is that the school act according to the policies stated in its own handbook, which are based on the Scottish Government’s current guidance letter. Both the handbook and the guidance letter say, in identical language, that “[M]any school communities contain pupils and staff from faiths other than Christianity or with no faith commitment, and this must be taken fully into account in supporting spiritual development. It is of central importance that all pupils and staff can participate with integrity in forms of religious observance without compromise to their personal faith” and that “There should be a clear distinction between assemblies devised for the purpose of religious observance and assemblies for other purposes such as celebrating success.”
There should be a clear distinction between assemblies devised for the purpose of religious observance and assemblies for other purposes such as celebrating success.
(School handbook; also official Scottish Government guidance)
The Church of Scotland has also expressed remarkably similar views. In a 2013 submission to the Public Petitions Committee, objecting to the Scottish Secular Society’s plea to change Religious Observance from opt-out to opt-in, it stated that “What is defined now as Religious Observance in Schools is a pluralist approach in a pluralist society”, that Religious Observance events are “a place to encounter different beliefs and points of view, which are fundamental in making sense of the pluralist society in which we live”, and that “Religious Observance is not, and should never be confessional in nature (it is not worship nor can it be).”
What is defined now as Religious Observance in Schools is a pluralist approach in a pluralist society.
(Church of Scotland, to Scottish Parliament)
I also found in the Handbook a list of the members of the school chaplaincy team, at least as it was at the time of the last posted handbook edition, which would seem to be 2012. And while official bodies will not tell you the affiliations of school chaplains, regarding this as confidential personal information, a web search quickly showed that all were committed Protestant Christians, ranging from Episcopalian to extreme Evangelical . The Evangelicals meet on the school premises for Sunday morning worship, but there seems no reason to object to that so long as the school handles all requests for accommodation evenhandedly, and does not pressure students into attending.
Can such a team deliver the promised “pluralist approach in a pluralist society”? Not according to the latest (2011) census data. These show all non-Catholic Christians totalling 38% of the population, as against 44% for “no religion” or “no religion stated”. Even these numbers will underestimate dissent from religion, especially among the school’s students. The religious affiliations monitored by the Census do not necessarily imply religious practice or belief, and we also know that religiosity is greater among older Scots than among the young.
Two things follow. The students are merely asking that the school follow its own stated policies. And spiritual education, if indeed such a thing is possible, can no longer be left to churches in which so many of the students no longer believe.
The students’ representatives are also asking the School Administration to allow 16-year-old students to withdraw themselves directly from Religious Observance, without involving their parents. I find it strange that they even need to ask. We are talking about young people who are by law old enough to get married, or to vote in at least some crucial elections. The individuals we are discussing have also shown themselves capable of effective organisation, and of producing work clearly superior to their own local newspaper. And while the law may regard the decision to withdraw as one for the parents, the school has no legal right to enforce attendance on 16-year-olds anyway, so why should it even try to retain this right when it comes to one particular activity?
1] The Chaplaincy Team members, and their affiliations as revealed by an on-line search, are Rev Neil Dougall (St Andrew Blackadder Church of Scotland), Bill Nisbet (North Berwick Christian Fellowship) , Shiona Liddle (North Berwick Christian Youth Trust, Inspire), Rev Dr David Graham (Abbey Church of Scotland) and Rev John Lindsay (St Baldred’s Episcopalian). In addition, the local paper reporter covering the school is the Minister of Belhaven Parish Church, Rev Laurence Twaddle.
Inspire is a CofS/Fellowship joint venture, which gives out free rolls at its lunch club and is involved in the school play.
The Fellowship gives no details of its beliefs on its web page, but is affiliated to Scottish Network Churches, some at least of whose members believe in Noah’s Ark as a fact of history and the eternal punishment of unbelievers in the Lake of Fire.
Welcome. Who are you? How did you find me?
In the past couple of days, 10% of my page hits have come from Brazil. I’m delighted. Brazil is a battleground between the acceptors of scientific reality (who can claim some support from the Catholic Church) and invading Evangelicals and Seventh Day Adventists. These last are extreme creationists, not merely science-denying but science-distorting. They maintain that the entire geological record is due to Noah’s flood, that their own position differs from the scientific mainstream only in its choice of interpretation, and that mutations can only degrade and not create information. Students of creationism will recognise here all the worst features of Henry Morris’s Flood Geology, Ken Ham’s Answers in Genesis, and the intellectual distortions of the Intelligent Designers. So if this blog is service anywhere, it will be of service in Brazil.
It is clear why I want to be found by Brazilians, but why should Brazilians want to find me? I did have a public exchange with a creationist on the Brazilian Airforce Academy cultural website, Letras & e-Artes, and am told that my contribution was well received, but that was 18 months ago. I also, more recently, had a tedious Facebook debate with a self-styled Adventist theologian, who presented as if new coined arguments rebutted in the 1920s, but I doubt that her followers would be beating a path to my door.
And yet, I must be doing something that is of special value to readers in Brazil. What is it, and how do I set about doing the same elsewhere?
Why only Brazil?
I am posting this page from Jonathan Baker’s Age of Rocks here for several reasons. It is an extremely useful resource, well researched and well-written; the author addresses creationists with humanity and respect, even as he demolishes their position; and the author himself is a committed Christian (why that should matter to me, a free-thinking atheist, is something I explain below).
The evidence presented ranges from tree rings to topography to sedimentology to physical geography to archaeology and anthropology to geochemistry to the fossil record to radiometric dating to astrophysics. Many of these are topics I have touched on, for example in my discussions of the unconformity at Siccar Point, and the slowly cooled multiple lava flows and palaeosols of the Giants’ Causeway.
In each case, the reasoning is briefly described, with links to more detailed discussions, many framed specifically to refute creationist claims. By relegating those claims to second place, the author avoids the common mistake of teaching the very error that he is warning against. At the same time, he pays a respectful attention to his opponents, for reasons that he explains elsewhere in his blog, even as he dismantles their arguments.
Like the authors of EvoAnth and Leaving Fundamentalism, the author is at present a graduate student; welcome examples of how the web is democratising discourse, and how young scientists and educators are using the opportunity.
I commend this piece to all those who have to deal with creationism in schools and elsewhere, alongside such classics as 29+ Evidences for Macroevolution and Index to Creationist Claims, and hope that the author will continue to update and add to it as his own career progresses.
Like Dennis Venema at Biologos and Robert Wiens at Radiometric Dating – A Christian Perspective, the author is a committed Christian, thus helping to give the lie to the claim that Christian belief requires biblical literalism and the rejection of established science. This matters, since as I have argued before inviting creationists to abandon their deepest convictions is not likely to be the best way to change their minds. Research at Glasgow agrees with me on this. Life science entry classes there contain a sprinkling of creationists, most of whom abandon their creationism during the course, but without necessarily renouncing their religion. I should for completeness state my own view on religion, which is that believers face major problems in accepting reality. But they are their problems, not mine, and it is not my place to tell them how to deal with them.
I have one small technical quibble. Paragraphs 73 and 74 seem, for reasons of brevity, to run together separate things under the heading “argon-argon dating”. These are: Ar-36/Ar-40 comparisons, used to subtract out the contribution of any argon initially present; Ar-39/Ar-40 that uses Ar-39, produced from K-39 by irradiating the sample, as a proxy for K-39 and hence for K-40 (this is what is usually meant by “argon-argon dating”); and finally, Ar-39/Ar-40 combined with controlled heating to distinguish endogenous Ar-40 (which will be released at the same temperature as the Ar-39) from so-called “parentless” Ar-40 that has diffused in from other rocks, which will be released more readily.
But I digress, and it is time to let Jon speak for himself:
100 Reasons the Earth is Old
How do we know the Earth is older than literalistic readings of the Bible seem to imply?
Geologists have been wrestling with this question for centuries, especially those pioneers in the Earth sciences (e.g. Nicolas Steno, William Buckland, Hugh Miller, Thomas Chalmers, and even Charles Darwin) who were also devout clergymen or at least trained in natural theology. The 19th century in particular may be characterized by the massive, interdisciplinary effort that sought to answer the question scientifically: how old is the Earth? But it was not until the mid 20th century that all efforts began to converge on the value we accept today: 4.56 billion years.
Today, a resurgence of young-Earth creationism has many persuaded that science, when applied faithfully, still supports a much smaller age—close to only 6,000 years. While the arguments behind this movement are not convincing to professional geologists, as I’ve sought to elucidate on this blog, their popularity highlights the need to summarize coherently the positive evidences in favor of ‘deep time’. Below, I have compiled what I deem the 100 most convincing reasons—in no particular order—that the Earth is not less than 10,000 years old.
Those readers from a young-Earth background might be quick to point out that many of the evidences listed below have been refuted by creation ministries in their article databases. But that’s no coincidence. Those article databases are primarily built to rationalize to what are indeed strong evidences against the young-Earth position. So please note, I am keenly aware of those counter-arguments, and therefore I encourage you either to follow the links to in-depth discussions of each evidence or to contact me directly about why I find such counter-arguments unsatisfactory.
How do we know from geology that the Earth is greater than 10,000 years old?
- Tree-ring “long counts” from California, Central Europe, New Zealand, and Scandinavia extend up to ~13,000 years. These chronologies are constructed from hundreds of individual trees that overlap, so that even if a tree did produce multiple rings during a growth season, the ‘extra years’ would disappear in the correlation process. Even John Woodmorappe has written that these tree-ring chronologies cannot be explained by multiple rings being produced in a single year or the mismatch of individual tree records.
The oldest individual bristlecone pine trees date to ~5,000 years old by dendrochronology (ring counting), which is older than the traditional date for Noah’s flood. Since we have no reason to suspect that these trees could have formed multiple rings in any given year, these trees provide two constraints: 1) the flood, if it were global, occurred more than 5,064 years ago, and 2) the Earth’s surface, where the trees were growing, has been identical to modern day over the last 5,000 years. The latter point is important, because flood geologists must assume that catastrophic geological processes continued for centuries after the flood to explain Quaternary deposits and erosional features like Grand Canyon or the Channeled Scablands.
- Long-term records of glacial ice can be dated by counting annual layers beyond 10,000 years. These annual layers can be recognized not only by appearance, but variations in chemistry, which removes any assumptions about growth rate during these intervals and precludes the possibility that multiple rings formed each year.
- Varved sediments with more than 10,000 layers, such as Lake Sugietsu, Lake Van, and the Cariaco Basin, to name a few. Geologists don’t just assume that these layers are annual, but must demonstrate rigorously that each layer exhibits some kind of seasonal signal (characteristic isotopes, organic matter, or mineral content).
Radiocarbon calibration curves confirm that annual layers in trees and varved sediments are indeed annual. The radiocarbon age of annual layers within these deposits are always within ~10% of the age predicted by layer counting, back to nearly 50,000 years. If these layers accumulated catastrophically, or if the radiocarbon method were fundamentally flawed, we should not expect such a match. Additionally, since YEC’s suppose that radiocarbon ages are only apparently old (due to low 14C concentrations during and after the Flood), every marine, tree-ring, and varved lake chronology must be compressed down to ~4,000 years. In other words, the YEC paradigm would predict that trees, glaciers, corals, and seasonally active lakes regularly form 4-10 ‘annual’ bands every year. But they don’t.
- There is no radiocarbon in old samples, despite claims to the contrary. Geologically old samples of coal, diamonds, and graphite, for example, yield finite radiocarbon ages that are consistent with the expected level of contamination invariably introduced during sample collection and preparation.
- Continuous coral chronologies from modern communities (i.e. not buried in sediments) extend throughout the Holocene. Corals contain annual bands and may be combined like tree rings to construct long-term chronologies, or dated by the radiocarbon and/or U-Th method. Applying these tools, geologists use corals to reconstruct sea level over the last few tens of thousands of years (or more!).
Secondary cave formations, such as stalagmites, can form relatively quickly (1–2 mm/yr) in tropical climates or where summer monsoons bring large volumes of precipitation to the cave system. For caves found in temperate or arid climates, however, the growth rate of stalagmites can be incredibly slow (<0.1 mm/yr). Advanced techniques in U-Th disequilibrium dating confirm what geologists long suspected: these iconic formations took tens of thousands of years to reach heights of half a meter or more.
- Large subterranean caverns do not form overnight, especially outside of tropical climates. The dissolution of caves is a rather slow process, due to the limited solubility of calcite in very slightly acidic rainwater. Although the process can be accelerated in the presence of active soils or even hydrogen sulfide (a microbial byproduct of petroleum degradation), the sheer size of natural monuments like Mammoth Cave and Carlsbad Caverns cannot be explained in a young-Earth timeline, especially given that these caves are lavishly decorated by secondary formations, which themselves take thousands of years to form.
- Large terrestrial lakes and inland seas have accumulated more than 10,000 years worth of deposition. Examples include the Black Sea, Dead Sea, Caspian Sea, Lake Baikal, Great Salt Lake, Lake Van, Lake Ammersee, Lake Sugietsu, and Lake El’gygytgyn, to name a few. These lakes are dated by combinations of radiocarbon, annual band counts, and isotopic records that correspond to climatic trends from ice cores. Some contain evaporite layers, indicating that the lakes dried up in the past. In the cases of Dead Sea and Great Salt Lake, this happened many times in the past on glacial-interglacial scales.
- Lake Baikal in Siberia has collected sediments that are inconsistent with any catastrophic inflow from the surrounding region. The sediments at the lake bottom are rather fine-grained, free of terrestrial plant debris (aside from microscopic pollen near the shoreline), and contain abundant diatoms. These diatoms flourish in the summer months but settle very slowly to the lake bottom, so their presence throughout the sediment column confirms that sediments accumulated under normal conditions, similar to today. Therefore, we can confidently say that the lake basin is potentially millions of years old, given the sheer thickness of lake-bottom sediments.
- Well developed river flood plains span large areas of temperate and tropical regions of Earth. These flood plains develop over long intervals of time as periodic flooding and migration of the river channel slowly erode the bedrock down to a flat surface. Attempts to describe vast planation surfaces by the retreat of flood waters do not work, because during floods, erosion is localized in channels that form along ‘weak points’ in the underlying rock and sediment. If this erosion took place soon after the Flood, the sediment would still be soft, exacerbating the localization of erosion in deep channels.
Painfully slow erosional processes in modern deserts, involving wind, ground tremors, or even ice, are the best explanation for some rather bizarre boulders scattered across the dunes. Slow tumbling boulders in South American deserts, for example, had to be weathered slowly by wind in the arid highlands, and cosmogenic dating confirms their old age. Slithering stones of Death Valley, on the other hand, were proven to move only by seasonal ice. These findings imply that the modern landscape has changed little in thousands of years (if not millions!).
- Evidence for numerous glacial cycles during the Quaternary (i.e. the past 2.6 million years) is particularly abundant in the northern hemispheric continents of North America and Eurasia. These evidences include glacial tills and terminal moraines, which are buried within layers of Quaternary aged sediments. Between these glacially derived layers, relatively warm-weather plants populate the sediments of old river valleys, indicating that climate rebounded after each ice age to one similar to what we find today.
- Quaternary deposits and landscapes are far too complicated to have accumulated in the ~4,500 years following the Flood. Everywhere we look on Earth, we truly find evidence for ~2 million years worth of processes, whether at high latitudes (where we find evidence for repeated glaciations and deglaciations, separated by warm intervals) or in the tropics (where we find thick desert dune sequences alternating with humid intervals) or in the oceans (where 2 million+ years of Milankovitch cycles are recorded in only a few meters of silt and clay) or in the high mountains (where alpine valleys have been carved out by rivers or glaciers, then infilled by coarse sediment, then eroded again, etc.). Flood geologists unanimously assert that the Quaternary period represents the ‘post-Flood’ era, but there is good reason that conventional geologists ascribe a much longer age: 2.6 million years.
- Glacial tills from ancient glaciations, such as the ‘Snowball Earth’ episodes in the Late Proterozoic
and cold intervals beginning the Late Ordovician and Late Pennsylvanian periods, are found within the geological record and so must be reinterpreted by Flood geologists as submarine deposits of boulders and mud during Noah’s flood. Though ancient tills do occasionally resemble submarine flows, ancient glaciations are not inferred by these sedimentary deposits alone. Instead, a suite of geological data, from fossils to paleoceanographic data to rock chemistry, all support the idea that the whole Earth was much cooler when these tills were deposited.
- Continental ice sheets do not form in a matter of centuries, especially those that were more than a mile thick and extended in some cases to southern Siberia and the central Great Plains, USA. Flood geologists must maintain, however, that massive ice sheets nearly half the size of Russia not only grew, but melted entirely, then regrew, melted entirely, and regrew more than a dozen times in less than 200-700 years (the timeline depends on which YEC you ask!).
- Human occupations of nearly every continent can be demonstrated beyond 10,000 years, e.g. in South Africa, ruling out the possibility that humans repopulated the Earth after being obliterated only ~4,500 years ago.
- Ötzi the Iceman has frequently made headlines in creationist writings, because they accurately perceive this unique find as a challenge to the young-Earth timeline. The remains of this murdered Alpine farmer date to ~5,300 years old, which YEC’s arbitrarily dismiss as “inflated”. Regardless, they do admit that he lived sometime in the beginnings of human civilization (i.e. very soon after the Flood), and so they attempt to turn the argument on ‘evolutionists’ by emphasizing the level of technology (tools, agriculture) carried by Ötzi and his village—”How can this ‘primitive’ man be so advanced?” This response is a non sequitur, because the artifacts found with Ötzi are entirely compatible with reconstructed histories of European peoples. What YEC’s overlook is the geological context of the body: it was preserved in undisturbed ice near the top of a mountain range. This tells us that the morphology of the Alps has changed very littlesinceÖtzi was alive. So when did theAlpshave a chance to shed the kilometers of sediment that once covered their peaks? ThemountainsinwhichÖtzi wasfoundare indeed very ancient, far older than the body of this 5,300-year-old village outcast.
- Human settlements that are now submerged due to sea-level rise have been documented beneath the English Channel, North and Baltic seas, off the coast of Israel, Florida, and beneath the Black Sea, to name a few. For much of human history, global sea level was up to ~130 meters lower than today, exposing far more of the continental shelves and pushing ancient coastlines far away from their modern locations. This allowed for human settlements to develop in sites that are now completely submerged. Following the ice age, however, sea level rose sharply and reached near modern levels at ~8,000 years ago. Whatever the absolute timeline, the young-Earth view allows too little time for human populations to develop, migrate across the globe, and construct large settlements prior to the sea-level rise following the ice age (which they assert happened only a few centuries after Noah’s flood).
- Fossils record long histories of migration of animals from Eurasia to the “New World”, which cannot be accounted for in the young-Earth timeline. Large mammals such as mammoth, mastodon, and giant sloth reproduce far too slowly to account for the population sizes indicated by fossil graveyards between Siberia and the Americas.
- There is no record of migration from Central Asia to Australia for many species unique to the land down under. Their ancestors, however, are found in the fossil record and imply that modern populations derived from species that arrived to the island well in the distant past, not after the Flood only ~4,000 years ago.
- Modern oceans are too salty to have been formed only ~6,000 years ago. We know this salt was delivered slowly to the oceans mainly via rivers (i.e. as opposed to being created in situ), because the relative abundance of salts in the ocean is related to their relative solubilities and abundance in the Earth’s surface.
- Cenozoic aged marine sediments in the Gulf of Mexico or along the west African and east South American coastlines, for example, are far too thick to be explained by ‘post-Flood’ processes. This fact has caused some YEC’s, such as Michael Oard, to push the ‘post-Flood’ boundary later and later into the Cenozoic and consider these marine sediments as Flood deposits. However, the structure of marine sediments in the Gulf of Mexico and the equatorial Atlantic is clearly related to the modern topography, where large rivers like the Mississippi, Amazon, Congo, and Cross have dumped tons of sediment into the seas, causing massive deltas to form over long periods of time. Due to the economic reward for exploring these sites (which contain abundant oil), geologists have thoroughly mapped out the evolution of ancient deltas through miles of sediment. Their result ubiquitously inform us that the modern landscape is very old and rather stable, and that these late Cenozoic marine sediments were not deposited through catastrophic processes, but by everyday rivers at rates observed today.
- Deep ocean sediments take far too long to settle to have accumulated in less than 5,000 years. Today, the entire seafloor is covered with microscopic species of plankton, diatoms, radiolaria, etc., in addition to tiny bits of clay and calcite. These particles are so small, that they would remain in suspension under flowing water, so their presence on the seafloor must be explained by a long-time in which they could settle through miles of seawater. The history of seafloor sediments is further amplified by the fact that marine tephra (volcanic ash layers) occur throughout marine cores around the world, but volcanic ash also needs time and calm water to settle out.
Volcanic ash beds (sedimentary tuff), frequently used to date sedimentary rock layers, were mainly deposited in dry conditions. Geologists can distinguish between ash layers that settled in ocean basins (marine tephra) and those that fell over dry land (air fall deposits). When volcanic ash is deposited in flowing water, it produces yet different features identifiable in outcrops, such as grain sorting and lamination. Therefore, not a few volcanic ashes in sedimentary strata contradict the Flood geology scenario, especially because these ash falls take time to accumulate from the air and harden to the point that water-lain sediments can be deposited on top without compromising the structure of the soft ash.
- The geologic column is no remnant of an ancient flood deposit, global or not. Fine details, in the form of thin layers of alternating clay and limestone, or irregular sand deposits that resemble modern river channels, defy catastrophic explanation, which explains why catastrophism has long been abandoned by research geologists.
- There are simply too many sediments buried in the crust to be explained in a young Earth. Contrary to the claims of Andrew Snelling, the ocean floor contains about as much sediment as we might expect after ~160 million years. In addition to ocean sediments still underwater, however, YEC’s must also explain the origin of the trillions of trillions of tons of limestone, sandstone, and mudstone now buried on the continents. These sediments, comprised of broken down minerals, must have originally weathered from igneous or metamorphic material, after which it was sorted by size through surface processes (like rivers, winds, and gravity). But this is not a rapid process, inviting the question: even if a global flood could have buried this much sediment (it can’t), what is the origin of the sediment in the first place?
- The distribution of sedimentary rocks is weighted too heavily over the continents, which is the opposite of what we’d expect in a global flood. Floods move sediments from high elevation to low elevation, depositing them in sedimentary basins. During the Flood, the oceans would have constituted the largest and deepest basins, but most sediments remainedonelevated continents. How did this happen? Did the laws of physics stop working?
- Angular unconformities became one of the principal evidences against catastrophism in the 19th century, and for good reason. For an angular unconformity to develop, a sequence of sedimentary layers must be deposited horizontally, then tilted or folded above horizontal, then eroded along a flat (or nearly flat) surface, after which new layers are deposited horizontally on top of the erosional surface. We can explain all these steps through modern geological processes. Flood geologists, on the other hand, must explain 1) how these horizontal strata became angled amid the flood, 2) had time to erode to relatively flat surfaces, and 3) why we do not find deep canyons associated with unconformity surfaces, since deep, rapid flowing water would tend to carve into the unconsolidated sediment.
- This buried landscape, for which little explanation is needed, absolutely defies Flood geology. It is rather a testament to deep time, in which an ancient river valley cut its way though thick sequences of sedimentary rock, only to be buried suddenly and preserved in subtle disconformities between the overlying layers. But these disconformities make for excellent acoustic reflectors, and so the ancient landscape is visible through seismic imaging—a way of treating the Earth to a million-dollar ultrasound.
- Sedimentary features in limestone are similar to those forming today in shallow marine environments. Everything from ooids (tiny spheres that build up like snowballs under wave action) to cross bedding to mudcracks to karst dissolution in ancient limestones falsifies the young-Earth timeline, because these limestone formations were deposited in calm, shallow seas—not a deep, worldwide flood.
- Exposure surfaces in limestone are recognizable through features like mudcracks, hardgrounds, and karst dissolution. Karst erosion takes place when relatively acidic waters (like fresh rainfall) dissolve cavities in exposed layers of hardened lime mud. Since karstic surfaces are found throughout the geologic column (including in the Redwall Limestone of Grand Canyon), we can rule out the possibility that limestone layers accumulated under a global flood.
- Carbonate rocks (limestone and dolostone) comprise more than 20% of all sedimentary rocks, but Flood geologists cannot explain extensive formations of dolostone—(Mg,Ca)CO3—which forms only under unique conditions not seen today in the oceans. To avoid the problem, they speculate that enhanced delivery of magnesium to the ocean (via deep-ocean vents, or the “fountains of the deep”) would havedriventhe formationofdolostone during the Flood. But in fact, dolomite does not form under these conditions, and so the Flood geology model predicts rather that mostcarbonatesshouldbecomprised of aragonite, the high-magnesium variant of calcite. Every piece of dolomite in the geologic record is firm evidence against the Flood model.
- Flood geology cannot explain the size and presence of massive evaporite deposits in basins like the Gulf of Mexico or the Mediterranean Sea (a small sampling of the world’s sedimentary salt). Halite (NaCl; same as the salt on your food) is extremely soluble in water, especially at higher temperatures. Therefore, Flood waters would have had to evaporate within individual basins until <10% of the original water mass remained (meaning millions of cubic kilometers were evaporated!). Again, this would imply that the ground was exposed at numerous points during the Flood (contrary to scripture). But it also requires that extreme evaporation could persist over significant intervals of the Flood (during which no water flooded the basins?), which is not physically possible. Evaporation stops when relative humidity in the atmosphere reaches ~100%, but the more water is evaporated, the greater the relative humidity becomes. At 100%, the humidity returns to the ocean as rain. Thus the hydrological cycle would have prevented any large basin from evaporating enough water to deposit halite over its base.
- The size and thickness of chalk deposits has frequently been cited as solid evidence against the flood. Young-Earth geologists (esp. Andrew Snelling) have responded by offering pseudo-scientific calculations that supposedly account for the global mass of chalk. These calculations are scientifically meaningless, however, because 1) they assume that coccolithophores (which form chalk in the surface ocean) sustained unreasonably high productivity rates over a significant portion of years leading up to the Flood, 2) that the “fountains of the deep” provided nutrients to the surface ocean (instead of poisoning them, as discussed above), and 3) that all chalk produced prior to and during the Flood could have settled in a coherent deposit at the bottom of the sea (rather than remaining in suspension and mixing with other particles in the surface ocean—a more likely scenario if the Flood was accompanied by strong currents).
- Syntectonic deposits are abundant throughout the sedimentary record. As the name implies, syntectonic deposits form simultaneously with tectonic deformation of the local geology. If you’ve ever seen an alluvial fan collecting sediments from the side of a mountain, especially near a large fault, then you can visualize the painfully slow process in action. As the mountainside is exposed little by little, due to adjacent valley dropping in elevation every time an earthquake hits, pebbles and boulders are episodically washed into the valley. Because syntectonic deposits contain eroded pebbles and boulders of underlying sedimentary rocks, their presence in the geologic column makes no sense within a ‘Flood geology’ interpretation. Those underlying sediments must have been solid before they could be broken off and polished into smooth boulders found inmostsyntectonic layers.
- Large extensional basins, such as Death Valley and the Great Basin in the US, contain thousands of meters of coarse sediments that were eroded from the adjacent ranges. These basins only deepen when infrequent, large earthquakes cause the valley to drop 1–2 meters at a time. Even if we allow that earthquakes were more frequent in the past, there is a limit to how fast semi-arid valleys can collect millions of tons of boulders in their center, because major flooding events are required to move these sediments several miles over a shallow slope.
- The total offset in large transform faults, such as the San Andreas fault, points to a very long history of slow deformation. Since its inception, the San Andreas fault has separated sedimentary deposits that appear on both sides by 150 miles, but the average slip rate today is only ~5 cm/yr. One could argue that the rate was higher in the past, but there is no direct evidence for this, and large episodic earthquakes can shift the fault blocks locally by only a few meters. On the other hand, there is evidence from the offset of modern gullies and streams that movement has been just as slow in the past.
- Radiometric dating confirms that modern slip rates of tectonic plates, as estimated by GPS data, remained relatively constant over millions of years. The ability to predict radiometric dates by uniformitarian ‘assumptions’ strongly corroborates plate tectonic theory and removes the assumption of uniformity of process.
- The abundance of oil in sedimentary rocks completely contradicts the young-Earth timeline, because oil cannot form within ~5,000 years at temperatures less than ~300°C—far greater than is found in every oil and gas field today. At best, the young-Earth scenario might predict sparse fields of natural gas, being produced by decaying organic matter, but instead we find hundreds of reservoirs containing billions of barrels of oil.
- There is too much organic matter in Earth’s crust to have been buried in a single flood event. Flood geologists must contend that most (if not all) of this organic matter—called the biomass—was alive or only recently deadjustprior to the flood. Coal and oil reserves are the most obvious examples of ancient biomass, but nearly every sedimentaryrockcontains a little (up to 1%) by weight. When allsourcesare taken into account, we find that the biomass buried in Earth’s crust is 3,000 times larger than what is found today—far more than could have been present on Earth at any given time.
- Coal beds defy rapid deposition, because the high concentration of organic matter begins with the slow accumulation of plant material in oxygen-poor swamps (and not by rapid burial of floating forests). The occasional preservation of leaves and woody material in coal seams would not be possible if all the buried plant material were fresh to begin with (as with rapid burial of existing forests), but requires that organic remains be at varying stages of decomposition.
- Coalification (turning plant matter into high-grade coal) is a slow process, which cannot be compressed to the young-Earth timeline. Experimental attempts to make artificial coal (cited by Snelling here) have only produced very low-grade lignite and coalified wood. Furthermore, these experimental setups (which do require high pressure/temperature and up to several months) rarely reflect natural settings and have yet to produce coal that closely resembles natural samples.
- If the majority of the Earth’s sedimentary rocks were deposited within a single flood, then those sediments should all be at approximately the same temperature today, and that temperature should be similar to the average water temperature during the Flood. It would take millions of years for a smooth temperature gradient to form (cool at the surface, hotter nearer the mantle), which is what we find today in deep wells.
- Remnants of soft tissue are extreme rarities in sediments older than Quaternary, possibly preserved in a handful of samples around the globe. Paleontologists continue to debate, for example, whether soft tissue in dinosaur bones derived from actual dinosaurs or microbial biofilms. But whatever the answer, we can all be confident that soft tissues are not regularly recoverable from Paleozoic and Mesozoic fossils. If these organisms were buried less than 5,000 years ago, however, soft tissues should be the rule, not the exception. According to the YEC timeline, mammoths and other megafauna died only years to centuries after the dinosaurs, yet we find hair, collagen, and even DNA in these animals all the time. So why not in dinosaurs and trilobites?
- Contrary to what we might expect from a Flood geology scenario, deep reservoirs of groundwater are not remnants of ancient oceans, but were accumulated by infiltrating rain and snow. Whenever oil companies drill deep into sediments, they always encounter very salty water (called connate water), whichhasto be pumped before oil is accessible. It was originally thoughtthatthe salinity of these waters derived from the oceans in which thesedimentswere deposited, but their chemical and stable-isotope signatures contradicted this hypothesis. Flood geology has no room in its
timeline for sedimentary rocks to have been ‘flushed out’ by infiltrating precipitation, because deposition would have to occur too rapidly. If the geologic column were deposited in a global flood, therefore, we should expect the groundwater trapped in deep sedimentary layers to be the very ocean water that once covered the Earth.
- Contrary to YEC claims, polystrate fossils are better interpreted by conventional geology and contradict the Flood geology paradigm. Most polystrate trees are rooted in organic-rich layers such as coal seams or paleosol beds. In other words, the trees were growing in place when covered abruptly by rising floodwaters, and were not uprooted and transported long distances. This means that after the formation of the coal/paleosol, there had to be time for a forest of trees to grow several meters, after which a large flood (not global, just the kind that would engage our National Guard today) buried whole stumps up to a couple meters with sand and mud. In all occurrences of polystrate trees, the tops of the trees are missing (truncated), having rotted off after they were exposed above the sediments for a long time.
- Fossilized burrows and marine trackways reflect everyday conditions in ancient ecosystems, where worms, trilobites, or molluscs dug calmly through soft mud on the seafloor in search of food. The claim that paleontologists have unanimously mistaken these trackways for escape efforts during a catastrophic flood is not only presumptuous, but it ignores the bulk evidence.
- Mudcracks are common features in layers of sand, silt, and clay that are interpreted to have formed in floodplains or shallow lakes and tidal flats. Despite decades of being aware of the problem, Flood geologists have not satisfactorily been able to explain why mudcracks cover thousands of individual layers throughout the rock record. These features do not form under water, but require an exposed, drying surface of semi-cohesive sediment.
- Ripples readily form in sandstone under flowing water, but not at speeds required by the Flood. Therefore, the common preservation of small ripples cannot be reconciled with the Flood model, but rather tells us that the sand must have been buried in calm seas with gentle waves.
- Raindrops on the surface of sedimentary layers—these are relatively self-explanatory. If we take Genesis as our guide, sedimentary layers could not be exposed during the course of the Flood, and so we should never expect to find raindrops imprinting their surface. Even if we do allow forthisunbiblical possibility, however, raindrops imprints cannot be preserved if they are swiftly covered by a new layer of sediment. For raindrops to become ‘fossilized’, theimprintmust be made in a semi-cohesive layer (i.e. one that is not saturated with water, but not completely hard), which needs time to
harden slightly in the absence of flowing water before another layer is deposited on top. Raindrops in sediments contradict flood geology outright.
- Fossilized poop, called coprolite, is found throughout the fossil record alongside the animals that produced them. These paleontological oddities are indicative of normal ecological conditions and contradict any scenario in which the ‘poopers’ were catastrophically buried.
- The nature of the fossil record contradicts the expectation of ‘rapid burial’ for most land-dwelling organisms. By and large, terrestrial fossils are the weathered remains of animals, which were long exposed to the elements before disarticulating and washing into a river channel, lake, or floodplain. Vertebrate skeletons are almost never found intact, and more weather-resistant pieces (like tooth enamel) are preferentially preserved, suggesting that rapid (live) burial was an extreme rarity in geologic history.
- Fine sorting of marine microfossils is inconsistent with the Flood scenario, because specimens of foraminifera, radiolarians, and coccolithophores are approximately the same size. Therefore, these tiny shells should be scattered stochastically throughout the sedimentary record, if they were subject to the same hydrodynamic forces of a single global flood. Instead, individual species are commonly confined to narrow zones in the fossil record and used as index fossils for dating layers of marine sediments.
Fossilized tracks in eolian (desert dune) deposits, such as the Coconino and Navajo sandstones, are inconsistent with the young-Earth proposition that these sediments accumulated under water. Extremely high sustained flow rates (>2 m/s) of very deep waters (up to 100 m or more) are required to form dunes of comparable size to those in the Coconino and Navajo sandstones. At these flow rates, it would be impossible for any submerged animals (especially small reptiles) even to make contact with the sediment surface, let alone for any prints to be preserved.
- The occurrence of widespread, eolian sandstone formations negates any model that cites a worldwide flood to explain their deposition. Of course, Flood geologists attempt to argue that eolian sandstones must have been laid down by water (more than 100 meters deep, flowing more than 2 m/s), but ignore the preponderance of evidence, which is more consistent with dry dune deposition.
- Paleosols are sedimentary layers that show evidence of soil formation by plants and microorganisms. Typically they can be recognized by distinct mineral compositions or chemical signatures, but direct reworking of sediment through biological agents may also be observed (for example, in situ roots and carbonate nodules). Not all paleosols show the same degree of soil development, but all are indicative of a long-lasting stable surface. YEC’s are forced to reinterpret paleosols as artifacts of chemical modification after rapid burial during the Flood, but geologists have become acutely aware of how to distinguish between these processes and true soil horizons.
- Animal tracks in general are evidence of an exposed surface, on which sediments were somewhat coherent (i.e. not too soft, not too hard; imagine trying to preserve your own handprint in cement). Nonetheless, YEC’s have deemed trackways consistent with their paradigm, because they insist that the floodwaters receded and covered the land numerous times. Besides the fact that Genesis 8 tells us the surface was not exposed until very late in the flood (and so their model contradicts scripture), it is very unlikely that any tracks could be preserved in those conditions. Once the floodwaters returned, they would tend toward erosional processes (removal of the entire surface layer, tracks included). The Flood model firmly predicts the absence of trackways in the sedimentary record, but in fact they are abundant.
- Fossilized nests, e.g. from dinosaurs, are indicative of stable, everyday ecosystems, and not catastrophic flooding of the continents. Both nests and eggs are fragile, which explains their rarity in the rock record. But abrupt burial in a high-energy flood cannot possibly explain their occasional preservation.
- The Grand Canyon was eroded and widened slowly by annual precipitation, as evidenced by the fact that the North Rim lies further from the main course of the Colorado River. A very gentle slope causes more runoff to enter the canyon from the north side, which, as Wayne Ranney (2012) explains, allows “for more erosion in the side streams on the north side of the river. For this reason, the North Rim is eroded away from the river about twice as far as the South Rim.”
- The Grand Canyon itself is only deepened episodically during extremely high floods, which do not regularly occur in the modern climate of northern Arizona. Therefore, it must have taken numerous glacial cycles, during which the jet streams migrate southward and bring more rain/snow to the American southwest, to account for the great depth of the canyon today.
- The walls of the Grand Canyon contain numerous caves with speleothems, implying that the water table once stood high above its present position for extended periods of time. Catastrophic carving of the Grand Canyon cannot possibly explain these features, because it allows no time for caves to form and no mechanism by which they could be decorated with stalagmites and stalactites.
Stromatolites and thrombolites are fine-laminated mounds built by algae and other microorganisms. These features not only take long periods of time to form, but their occurrence in repeated sedimentary layers argues strongly against catastrophic burial. They do not appear randomly in the geologic column, but are always positioned upright (in situ growth position) over wide areas within single layers of limestone—precisely what we’d expect if they grew in ancient oceans that slowly amassed limestone mud. Finally, these laminated mounds are frequently surrounded by fragmented shells of shallow-marine organisms typical of the same environment.
- Consistent patterns in magnetic reversals recorded on the seafloor strongly support the conventional model of plate tectonics, in which slowly forming oceanic basalts record the dominant magnetic signature at the time they were formed. YEC’s contend that these magnetic reversals occurred rapidly during the flood, but this proposal is easily falsified. If the entire Atlantic and Pacific basins formed during and/or shortly after the Flood, then Earth’s polarity would have reversed multiple times before oceanic basalts even had a chance to cool and preserve the signature! Flood geology thus predicts that either a single polarity signature should persist across ocean basins or the signature should be stochastic, with no striped pattern.
- Magnetic reversals recorded on the seafloor correlate to magnetic patterns in land sediments (e.g. Heller and Tung-Sheng, 1982; Cunningham et al., 1994; Ding et al., 1999), vastly improving the dating of continental deposits that lack datable layers of volcanic ash. Where ash layers do exist, they allow for independent dating of magnetic reversals on land by the Ar-Ar method. This independent corroboration of dates improves the strength of magnetic ‘stripes’ on the ocean floor as evidence for an ancient Earth.
- Earth’s magnetic field is not decaying exponentially, but has varied much less over the past 7–9,000 years (e.g. Korte et al., 2011; Nilsson et al., 2014). Magnetic field strength was weaker, not exponentially stronger, for much of this interval. Attempts to suggest that the Earth cannot be older than 10,000 years due to an exponential decay of Earth’s magneticfieldare based on a blind extrapolation of historical measurements (which span no more than 150 years) into the past. This approachignoresthe abundance of paleomagnetic data from human artifacts, sediments, and recent lava flows.
- The entire field of chemostratigraphy makes no sense within Flood geology. First, the stratigraphic shifts in chemistry—meaning, as we analyze rock chemistry from the bottom of the geologic column to the top—are too large to have occurred during a single year. This is true particularly of isotopes of carbon, sulfur, and strontium, because the amount of these elements dissolved in the ocean is too large to be greatly affected within a short period of time. It would be like trying to change the water color of a swimming pool by dumping in a few cups of coffee!
- Event stratigraphy, which utilizes abrupt shifts in rock chemistry as time markers, helps geologists to correlate sedimentary rocks from very different parts of the world. When we examine sequences of sedimentary rocks that are rich in fossils, the order and timing of chemical events just happens to correspond to the order and timing of fossil events (e.g. the disappearance or first appearance of certain fossil species). This correspondence is not possible in the flood geology model, however, since the ordering of fossils in various parts of the world could not have been a matter of timing (i.e. it couldn’t depend on which day of the Flood they were buried).
- The mere existence of isotopes is not predicted by the young-Earth paradigm, but makes sense only in conventional astrophysics. Nearly all elements of the periodic table exist in various isotopes, due to their being formed in the process of stellar evolution. As stars grow larger, heavier elements are produced through nuclear synthesis. Outside of this mechanism, we should not expect isotopes to be a common feature in basic chemistry.
- Short-lived isotopes are detectable only from distant supernovas. These are unstable elements that decay relatively rapidly after formation and so should be absent in a 4.5-billion-year Earth. This discrepancy provides unambiguous support for the conventional age of our solar system and models of stellar evolution.
- Radiometric dating of chondritic meteorites is consistent between methods and yields ages of 4.56 billion years for our solar system. It is currently inconceivable how this date could be wrong by a factor of 1 million.
- Potassium-argon dating is well known for its potential problems, but still provides one of the best methods for dating ancient volcanic flows. Even when excess argon is originally present, as is evident in the dating of certain historical eruptions, the date is only apparently too old by a few million years at most. Therefore, K-Ar dates in excess of tens or hundreds of millions of years tell us clearly that the Earth is not young, because otherwise, we could not explain such high concentrations of argon in these volcanic rocks.
- The Argon-Argon technique removes most uncertainties about the original presence of excess argon in samples, confirming that K-Ar dates are both real and generally accurate. Corroboration of Ar-Ar dates by other methods—e.g. when applied to the Cardenas Basalts of the Grand Canyon—further improves our confidence in the respective techniques.
- Uranium-Lead dating techniques consider the decay of multiple isotopes (238U, 235U, and 232Th) into stable forms of lead. If the respective half-lives of these elements changed significantly in the past, then the technique simply wouldn’t work, because each half-life is vastly different. Accelerated nuclear decay, in other words, would result in massive discordance between age estimates from each decay chain. However, the U-Th-Pb method, especially when applied to pristine zircons, provides one of the most precise geochronometers for the bulk of Earth history.
- Flood geologists cannot account for the abundance of 230Th in secondary calcite deposits, such as speleothems, carbonate lake sediments, and corals. Since thorium is not soluble in oxidized water, these formations originally contained none. Therefore, present concentrations can only be accounted for by radioactive decay of 234U into 230Th, which has a half-life of 245,000 years. If modern corals, lakes, and cave deposits formed only after a global flood, some 5,000 years ago, then none should yield dates older than this.
- Cosmogenic dating utilizes short-lived isotopes that are created in situ by incoming solar radiation or high-energy particles from space. When rocks are exposed to the atmosphere, such as large boulders on the side of a mountain, they accumulate short-lived isotopes. When rocks and minerals are hidden, through burial under sediments or ice, short-lived isotopes decay at a known rate. Through a variety of methods, geologists have used cosmogenic dating methods to constrain the buildup and retreat of large ice sheets, development of alluvial fans, river plains, deserts, and other surface features across Earth. Of course, these dates invariably suggest that the most recent deposits on Earth are not less than 10,000 years.
- There is too much helium in zircons, contrary to what Russell Humphreys has conjectured in his unscientific analysis. Geologists regularly use the amount of helium in certain minerals to constrain rates of tectonic uplift, because it accumulates at a known rate (dependingonthe concentration of Uranium/Thorium), so long as the mineral stays below a threshold temperature. This method (U-Th-Hethermochronology) regularly yields ages of tens of millions of years, which is to say that many millions ofyearswere required to account for modern concentrations of helium.
- Ophiolites are remnants of ancient oceanic crust, which have been thrust onto the continent. Geologists were originally confused by the large bodies of ultramafic (super rich in Fe and Mg) rocks on land. But by studying the chemistry and mineral composition of ophiolites, geologists recognized their oceanic origin and could identify the processes responsible for their formation. As it turns out, most ophiolites were formed near subduction zones (e.g. like we find around the Phillipines), and not in mid-ocean ridges. We know this because subduction of ocean sediments and crust influences the chemistry of newly formed lavas in a very specific way. And so, ophiolites tell a much longer story than the YEC could allow, in which 1) ancient (pre-Flood?) oceanic crust began to buckle until one plate subducted beneath another, 2) forming an island chain like Japan, which 3) began to stretch away from the continent, 4) allowing new oceanic crust to form, until 5) the entire suite was crumpled up as the island chain collided with the main continent, 6) ultimately preserving portions of the ocean crust and overlying sediments on land. Each of these steps requires more than a few thousand years.
- Cosmogenic beryllium (10Be) is present in volcanic emissions above young subduction zones, but absent in older ocean sediments. This radioactive isotope is formed continuously in the atmosphere, much like radiocarbon, but has a much longer half life. It is useful in dating certain marine cores, since the concentration of 10Be decreases with depth—as expected if the ocean sediments accumulated over millions of years. The fact that 10Be is present in younger subduction zones, such as the Lesser Antilles, indicates that ocean sediments were subducted and then recycled back into recent volcanic flows within a few million years. Since 10Be is absent, however, from the majority of volcanic emissions and from ocean sediments that are older than Pliocene in age, we can be confident in their conventional ages (>5 million years).
- Large igneous bodies take time to cool, such as those that comprise the core of the Sierra Nevadas, Andes, Rocky Mountains, and other large mountain belts around the world. Even in the presence of circulating waters, the sheer amount of heat originally present in magmatic intrusions requires hundreds of thousands to millions of years to dissipate, before the magma may crystallize completely into solid rock. This process is slowed significantly by overlying sediments, which act as insulators.
Coarse grains in igneous intrusions confirm that they indeed cooled very slowly, and not by rapid dissipation of heat via water or any other process. Only slow cooling allows for large, distinct minerals to form (called phaneritic texture), as is common in granite and diorite. Whenever you find a rock that resembles the image to the right, you have met a witness against the young-Earth paradigm.
- The intrusive igneous rocks exposed today were formed at great depths, indicating that miles of solid rock had to be weathered and eroded in the past. Even under catastrophic conditions, this process alone could take tens of millions of years. Today, granite exposures such as in the iconic Yosemite Valley continue to uplift in response to the removal of the overlying rock.
- Volcanic sills, which are intruded between sedimentary strata, require that the layers be hardened first. Otherwise, these lava injections have no physical guide that would confine their shape to lateral sheets of basalt. It is the brittle break between solid sedimentary rocks that causes volcanic sills to parallel the direction of bedding. Where is there time in Flood geology for sediments to harden completely, then to fracture and allow injection to form a sill, and finally time for cooling of the lava itself into solid rock? Volcanic dykes similarly require brittle fractures in the rock layers to explain their shape.
- Volcanic island chains, such as Hawaii, elucidate the multimillion-year effects of plate tectonic theory. Migrating lithospheric plates (and/or ‘hot spots’) cause the center of volcanic activity to migrate in a roughly linear pattern, resulting in a long chain of individual islands (which themselves are large volcanoes). Radiometric dating of volcanoes, from recently active to long extinct, confirms the predicted rate of plate motion based on modern observed values.
- Even if one rejects these dates, we must still account for the sheer size of the subaqueous mountain belts, which form gradually by periodic eruptions. It takes time for one deposit to cool and solidify, before another can be laid on top. Otherwise, a 33,500-foot shield volcano could not form, but only a relatively flat plateau of flood basalts on the seafloor.
Volcanoes would have destroyed all life on Earth, assuming that volcanic deposits now preserved in the geologic column had to have formed during a single year. Massive eruptions have been well preserved, for example, in the Deccan traps (Siberia) or in flood basalts of the Snake River basin (northwestern U.S.). Geologists have modeled the impact of these individual lava flows on terrestrial and ocean life, and consistently conclude that each could have contributed to dramatic climate change and major extinction events. But these models assume that lava of the Deccan traps, for example, erupted over hundreds of thousands of years. Cumulatively—and if we require that all eruptions took place during the Flood year—these volcanic flows would have poisoned the oceans with heavy metals and saturated the atmosphere with carbon dioxide and sulfur gases. The sheer amount of carbon dioxide would have driven the oceans toward acidic conditions too vile for any surface life.
- Carbon dioxide emissions from volcanic events would have driven atmospheric concentrations to ~50,000 ppm or more. That’s more than 1,000 times what we find today! There is no evidence, however, for the extreme heating of Earth’s surface that inevitably would have ensued (on the contrary, YEC’s believe an ice age followed the Flood). Additionally, not enough time has passed since the Flood for such high levels to have equilibrated to those observed prior to the modern industrial age. The mass of volcanic deposits within the geologic column precludes the Flood geology model entirely.
- Large metamorphic bodies do not form rapidly, but require hundreds of thousands to millions of years worth of circulating waters under intense heat and pressure. The notion that catastrophic plate tectonics can explain the metamorphism of extensive mountain belts has no basis in physical science.
Gemstones and other rare minerals form by slow accumulation of rare elements in magma or in water circulating through rocks. The greater the size, purity, and quality of gemstones, the longer it would have taken to form them. Gemstones are thus a testament to the antiquity of the Earth.
- Radiogenic isotopes in rocks from the crust to the deep mantle indicate a long history of chemical evolution deep within the Earth. As large igneous bodies cooled at the surface to create continental and oceanic crusts, some elements preferentially were incorporated into solid minerals, while others remained preferentially in the liquid mass in the mantle. This chemical differentiation explains very well the difference in isotope ratios between the crust and deep mantle rocks, assuming that it occurred over several billion years. Young-Earth geologists, on the other hand, cannot explain the most basic geochemical features of the Earth’s crust and mantle.
- Catastrophic plate tectonics is the only way to explain the bulk evidence for plate tectonic theory in a young-Earth timeline. But two major problems arise: excess heat and lack of a viable mechanism. Though YEC’s feel they have been able to model rapid subduction of the Earth’s crust (accounting for the mechanism), they certainly cannot explain how this process did not destroy the Earth’s surface in a giant heat death. Excess heat must have transferred to the oceans and the crust, which would destroyed all life on Earth.
- There is no evidence of excess heating from catastrophic plate tectonics. According to John Baumgardner, the excess heat diffused by evaporating a ~1.5-km-thick column of water over the oceans. He claims this is a answer to the ‘heat problem’ above, which he believes is physically “comprehensible”. But the geologic record shows no evidence of large scale heating of the oceans, such as might be expected in stable-isotope proxies that work as paleothermometers (such as δ18O and Mg/Ca in carbonates or δD in clay minerals).
Catastrophic plate tectonics cannot explain detailed formation of new oceanic crust, as is observed today at mid-ocean ridges. Oceanic crust is not a homogenous mass of basalt, but develops distinct textures from top to bottom, due to different cooling rates and chemical composition. If the ocean floor had to form rapidly (in a matter of years), we should not find these textures in older sections of oceanic crust, far away from modern spreading ridges.
- Seafloor basalt is modified geochemically by hydrothermal vents that form in fissures near mid-ocean ridges. These vents are powered by hot, upwelling seawater that originally infiltrated far away from the ridge, where temperatures are much cooler. However, the catastrophic plate tectonic model allows no time for this process and would have created a seafloor that was entirely too hot for effective hydrothermal circulation. Therefore, the catastrophic model is falsified by the thousands of studies of the ocean floor, which find evidence of alteration of seafloor basalts in very old parts of the crust (such as the western Pacific).
- Radiometric dating of seafloor basalt has produced a famously coherent pattern of increasing age away from mid-ocean ridges. The mapbelowis constructed by compiling thousands of analyses from dozensofindividual studies across the globe. Though young-Earth geologists will argueagainstthe validity of absolute ages, they still must explain the overall pattern, which makes no sense intheirparadigm (even invoking accelerated nuclear decay).
- The relative abundance of elements in the cosmos shows distinct patterns that make little sense in the young-Earth paradigm. For example, hydrogen and helium are super abundant compared to lithium, beryllium, and boron. Furthermore, elements of even atomic number are ~10 times more abundant than elements of odd atomic number. These relationships make sense in conventional astrophysics, because elements are produced over millions of years in dense stars through a process called nuclear synthesis. But YEC’s must explain them ad hoc:God simply created them like this.
- Components of our solar system, including the sun, meteorites, and planets, have approximately the same chemical composition (if volatile elements are excluded). This coincidence is shocking, unless we allow that each was drawn from a primordial mass, as described by the nebular hypothesis.
- Even the RATE team, a YEC think-tank seeking to undermine geochronology, has found no meaningful objection to the validity of radiometric dating techniques. Their proposal that radioactive decay rates increased by as much as a million times in the recent past is essentially a concession that geochronology works (they just refuse to accept the results), because…
- Accelerated nuclear decay is science fiction. Neither the physics nor the math produces a result in which radiometric dates yield consistently large ages for rocks and minerals in our solar system. One cannot tweak the physical properties of atoms, so as to increase the rate of radioactive decay, without all hell breaking loose—literally. Rates of decay depend on the stability of individual atoms, so if unstable atoms became more unstable, we’d expect stable atoms also to become very unstable, which would be the undoing of the physical universe as we know it. These are not conditions through which an Ark of humans and animals ever could have survived.
I have assembled a team to help prepare materials about evolution for the use of non-biologists, and we would welcome comments and suggestions. The topic arises in Religious Education in particular, hence the title of this post. Most of the material here is borrowed from an article by the Reverend Michael Roberts, retired Anglican Vicar, field geologist, School Governor, historian of ideas, and part of the team. But first, some background.
Recent developments increase the importance of what Michael has to say. The Society for Biology made two recommendations in its recent evidence to the Scottish Parliament. One, now incorporated into the stated Governmental position, was that creationism not be taught in a science class since it is not a scientific theory. The other was expressed as follows:
We recognise that questions regarding creationism and intelligent design may arise in the classroom, for example as a result of individual faith and beliefs or media coverage…
Furthermore we urge the Scottish Government to provide teachers with appropriate training opportunities to develop the skills to answer controversial questions posed in science lessons in a clear and sensitive manner.
The issues raised here are not confined to the science classroom, nor to Scotland. Religious reactions to such nineteenth century discoveries as the antiquity of the Earth, and the evolutionary relationships between living things, are and should be topics for discussion in the study of religion and of the history of ideas. Indeed, Creationism is singled out as a sub-topic in Scottish schools, as part of the syllabus for Religious, Moral, and Philosophical Studies (RMPS). My own view is that an emphasis on Creationism in particular is unfortunate, since this is the most contentious, unhelpful, and indefensible of the various religious responses. There is also a real risk that discussion of the relationship between ideas might get sidetracked into irrelevant, and long since resolved, disputes about the underlying facts. But no doubt good teaching will supply the necessary balance.
Evolution is about to become part of the national curriculum in England, and non-specialist teachers there are urgently seeking helpful materials. No wonder, when one considers what is involved. Explaining evolution is a formidable task, not made any easier by the existence of a campaign of theologically motivated disinformation.
Teachers should of course be aware of the overwhelming scientific consensus in favour of accepting the facts of evolution and an ancient Earth, and know something of the lines of evidence that led to it, such as those mentioned by Michael below. It would also be an advantage to know something about the geological column, and radiometric dating. They should understand the concepts of natural selection and mutation, but preferably be aware that much if not most evolution is apparently neutral drift. Things being what they are, they must also be prepared to discuss the “objections” to evolution, such as why there are still monkeys, isn’t evolution only a theory, the alleged poverty of the fossil record, and the “problem” of the origin of new information. Here great care is needed. It is best for many reasons to let students come to their own conclusions, rather than be told what to think, and yet we are lying to them if we leave them with the impression that this is still an open controversy within science. Moreover, teaching with an emphasis on refuting arguments may prove counter-effective.
Finally, as if this were not enough, teachers should have some knowledge of the range of religious responses, and should realise that the Churches had generally accepted an ancient Earth and the fact of evolution by the end of the 19th Century.
Anyway, it is time to let Michael speak for himself, in the excerpts below. The full article is here. Michael is of course a Christian, and is mainly addressing his fellow-Christians, but I think that all of us can learn from what he has to say. There are things in his article that I like in it, and things that I don’t, and, in the spirit of intellectual enquiry, I will let interested readers work out for themselves which is which.
TAKING EVOLUTION SERIOUSLY
In essence, biological evolution means that all life is descended from a common ancestor, most popularly that we are descended from apes. Parodies and misunderstandings abound, and there is a prevalent view that evolution excludes creation and thus God.
The genius of Darwin in “The Origin of Species” (1859) was that he brought together previously unrelated aspects to biology; Variation and selection (leading to Natural Selection), the Geological Record, Geographical Distribution and the “Mutual Affinities of Organic Beings”. One of the main “gaps” in Darwin’s theory was the problem of inheritance or genetics. The solution to this was provided by Gregor Mendel in the 1860s but remained unknown until the turn of the century.
Genetics was what biologists were looking for and this resulted in the 1940s “Neodarwinian Synthesis” of Darwinianism and Mendelism. This has been further modified by such concepts as neutral drift (Kimura 1968), punctuated equilibrium (or stop-go evolution; Gould and Eldredge 1972), and molecular phylogeny (predominantly 1990s onwards). So our present science of evolution is far in advance of the original neo-Darwinian synthesis, let alone anything that Darwin himself could have imagined, and our appreciation of evolution has been both deepened and strengthened in the process. Evolution is regarded as much of a fact as the sphericity of the earth, – and rightly so!
To summarise the most obvious arguments for Evolution, these are
1) The Evidence of the Fossil Record.
The geological record shows a progressive “appearance” of life. ; invertebrates with shells at the base of the Cambrian (550m.y.); Vertebrates (fish) in the middle Ordovician (460 m.y.); leading up to Mammals in the Jurassic (180 m.y.); and finally “Man” a few million years ago.
2) “Mutual Affinities”
There are great number of mutual affinities between all forms of life. For example the structure of all vertebrates have much in common. If, say, the fore limbs of a bird, a whale, a dog and a human are compared, they all have the same basic structure and are said to be homologous, and point to a common ancestor. Here is a diagram of homologies
3) Geographical Distribution.
The oddities of geographical distribution were explained before Darwin by holding that God created different creatures in different places. Thus, for example in the Galapagos Islands, which Darwin visited when on the Beagle in 1834, God with would have created umpteen different finches on different islands. Evolutionarily this is seen as common ancestral finches living in isolation on different islands, and then diverging over subsequent generations. On a longer timescale lifeforms before the Mesozoic in Africa and South America were similar, but have diverged since then. The classic example is the Wallace Line in the middle of Indonesia. The reason became clear with the discovery of Continental Drift which demonstrated that the two continents started to move apart during the Mesozoic.
[To these one could add residual organs, evidence from embryology, defects of design, and the relationships shown by molecular biology, among other things, but this might overburden both class and teacher.]
This is a terribly brief summary of Evolution, but there are many excellent non-technical books, such as Why Evolution is True (Jerry Coyne), Your Inner Fish (Neil Shubin), and The Incredible Unlikeliness of Being (Alice Roberts).
TAKING CREATION SERIOUSLY
Open any childrens’ Bible on the first page and you are usually confronted with an idealised picture of a giraffes and lions on Noah’s Ark.
Thus from an early age people are encouraged to believe in a literal six-24 hour day creation. This aids and abets youngsters to give up their faith at an early age, but the problem often persists to adulthood, leaving them with a nagging doubt that God could not have created the world, because Genesis is incompatible with science.
The Bible begins with the marvellous double “account” of Creation. I say double because Genesis 2 differs from Genesis 1. Genesis 1 is the best known with its structure of creation on six successive days. Approach it literally and you are in mess. Attempting to tie it in to scientific discovery always fails, as is inevitable as the Bible was “written” 3000 years before the rise of Geology. See it as a hymn to God the Creator and it comes to life. “In the beginning God created the heavens and the earth”. The focus is on God, the Rock of Ages, not the ages of rocks. Again “And God said” occurs nine times as an introductory formula for God’s creativity. Ultimately Genesis One is a “Whodunnit” not a “Howdunnit”!
Genesis 1 and 2 are not the only parts of the bible, which speak of God the Creator. Take the last five chapters of the Book of Job, or Isaiah chapter 40 from verse 12, some of the Psalms especially 8, 19,and 95 (the Venite) to mention a few from the Old Testament, and John chapter 1 and Colossians Chapter 1 verses 15 to 20., both of which speak of a “Cosmic” Christ.
Taking Creation seriously is an affirmation that God is the Creator of all that is, with a realisation that the Bible gives no scientific explanation. Science will inform our understanding of Creation, not overthrow it.
4004 B.C. AND ALL THAT.
In the margins of many old Bibles, we will find dates in years B.C. for the Old Testament. For Creation the date is 4004.B.C., and this date is usually ascribed to Archbishop Ussher of the seventeenth century. Up to 1650 most Jews and Christians reckoned the age of the earth to be a few thousands.
With the rise of scientists such as John Ray, Whiston and others before 1700 the earth was seen as somewhat older. The flowering of geology at the end of the eighteenth century, with Smith, Cuvier, de Saussure and Hutton, developed that further, and before long talk was of millions of years. Many of the early geologists were Anglican clergy and soon the churches took the vast age of the earth on board.
There were a minority of Christians who opposed geology, as did some of Faraday’s colleagues at the Royal Institution. However, by 1860 hardly any clergy or educated Christians believed in 4004.B.C. The Evangelical clergyman-astronomer Richard Main wrote, in 1862, “Some school-books still teach to the ignorant that the earth is 6,000 years old. No well-educated person of the present day shares that delusion.” (Alas, many share it in 2015!)
Putting actual dates to the age of the universe, the earth or rock strata proved difficult,
even after biblical chronology was dethroned. Late 19th Century geologists favoured an age of around 100 million years, but radiometric dating proved this time much too short. For forty years now the age of the earth has been unchallenged at 4,600 million years, the oldest rocks at a little over 4,000 million, and the base of the Cambrian at 550 million. Such numbers are mind-boggling, but then so are black holes and the structure of the atom.
(Recently, Creationists have tried to demonstrate that the geological methods are fatally flawed, and that the earth is but a few thousand years young. Not one of the Creationist arguments has any substance to it. It is sad to be so negative, but Creationism is a confused hot-potch of bad science, misunderstanding and misrepresentation.)
The problems some have over geology is caused by a too literal view of the Bible, and not allowing the pre-scientific biblical writers to communicate truth about God in a non-literal way. It also does not recognise that most educated Christians never took Genesis literally!
[Michael goes on to speak of the absurdities of literalism, the apparent belittlement of human life by incorporating it in the animal sphere, the concept of humankind as made “in the image of God”, the differences between methodological and philosophical naturalism (I have a piece of my own on this), and evolution’s dismissal of the concept of a designer, as in Dawkins’ book The Blind Watchmaker.]
An atheist will see “design” as a chance happening, a theist will see “design” as a recognition that God is above and behind all things: The heavens are telling the glory of God; and the firmament proclaims his handiwork (Psalm 19, verse 1)
However, not all “design” is beautiful; some is frankly horrific. Darwin could not see the work of a Benevolent Designer in the Ichneumon fly. This lovely little creature lays its eggs inside a caterpillar. The eggs hatch and proceed to eat the caterpillar alive, keeping it so until the larvae emerge. “Design” does not point conclusively to a Good God. Thus
Beauty of (apparent) design is a problem to the atheist; Suffering is a problem to the Theist.
THIS VIEW OF LIFE (AND DEATH)
Of the evolutionary picture Darwin said, “There is grandeur in this view of life”. But he should have added “AND DEATH”. The natural world is incredibly wasteful of life; just consider frogspawn. The spawn will produce hundreds of tadpoles, and if TWO survive to become frogs and breed, that is success. Three is a population explosion. The fate of the tadpoles is varied, some, to the horror of children, are eaten by other tadpoles. Then, one of my joys in late spring is to hear the Cuckoo calling. The music of the adult is not matched by the morality of its offspring casually heaving out its adopted kin. Life is shot through with suffering and death. Nature is Red in Tooth and Claw. Human life is also often cruel and short. Surely “an all powerful, all-loving God simply would not allow small children to die in screaming agony” (Michael Ruse, Taking Darwin Seriously)? Suffering is the great problem, whether personal, intellectual, or religious.
Contrast this with Milton’s view (Paradise Lost) that all suffering is the result of Adam and Eve’s sin. Since the rise of geology in 1800, this view has been untenable, but it has not always been possible to bury it, especially in popular Christianity. Very often Milton’s view is accepted as the traditional view. As the admirable Bishop Colenso said in 1863, “We literally groan, even in the present day, under the burden of Milton’s mythology.”
We still do.
[Michael continues his discussion of the problem of evil, in highly personal ways. Does it make sense to blame Adam and Eve for the fact that children are dying today of malaria? This lets God off the hook, but at what cost? He invites us, instead, to share Darwin’s contemplation of the tangled bank, and sees science as a way of understanding and appreciating the work of the Creator.]
It’s wrong when climate warming denialists tell lies, it’s wrong when Creationists tell lies, it’s wrong when anti-vaxxers tell lies, and it’s just as wrong when anti-frackers tell lies.
Cheap gas from fracking helps keep coal in the ground, and the industry is much more closely regulated than in the US. We can, and should, be discussing whether the environmental benefits outweigh the costs; gas only generates about half as much CO2 as its energy equivalent in coal, but any cheap fossil fuel undermines alternatives. We should also be examining the effectiveness and enforcement of environmental regulations, as for all major extraction and construction. Silly scare stories can only detract from these important debates.
h/t Michael Roberts
Well, perhaps not quite a scientist, but Pope Francis really does have, on his CV, a chemistry lab technician’s diploma and related work experience. And Rick Santorum is not quite a Senator, either, more of an ex-Senator, having lost his seat in 2006, but nonetheless a candidate (yet again) for the Presidency of the United States.
Pope Francis also worked for a while as a nightclub bouncer. Nothing to do with the matter in hand, but I thought I’d mention it.
As Santorum should know, Popes have for quite a while had a reasonably good record of listening to scientists. There was, of course, that unfortunate business of Galileo, but that was 380 years ago, his Dialogue Concerning the Two Chief World Systems was taken off the Index of Prohibited Books in 1835, and perhaps we should let bygones be bygones. More recently, the Big Bang Theory was first put forward by a Catholic priest, Georges Lemaître, working in a Catholic university. The Catholic Church has also accepted the fact of evolution for many decades, as laid out notably by John Paul II in his 1996 address to the Pontifical Academy of Sciences.
Here, in contrast, is part of Santorum’s record of science denial. He was responsible for what became known as the Santorum Amendment. This said that students studying evolution in US publicly funded schools should also study the “controversy”, i.e. Creationism and Intelligent Design. This passed the Senate in 1991 by a vote of 92-8, but failed to become law, in part because of the opposition of a coalition including 96 scientific organisations. Its spirit lives on, despite this opposition, in the “teach the controversy” campaign that continues to bedevil US science education.
However, it is not evolution that has led Santorum to upbraid the Pope, but the environment. Santorum stated during his last Presidential campaign that the idea of man-made climate change was
just patently absurd when you consider all of the other factors … a beautifully concocted scheme because they know that the earth is gonna cool and warm… just an excuse for more government control of your life, and I’ve never been for any scheme or even accepted the junk science behind the whole narrative.
Obviously, Santorum, unlike the Pope, was able to come to a conclusion about climate change without consulting any scientists. But if he was unwilling to listen to the scientists, one might have hoped that he would by now at least have listened to the Pentagon, which warns that
rising global temperatures, changing precipitation patterns, climbing sea levels, and more extreme weather events will intensify the challenges of global instability, hunger, poverty, and conflict. They will likely lead to food and water shortages, pandemic disease, disputes over refugees and resources, and destruction by natural disasters in regions across the globe.
In our defense strategy, we refer to climate change as a “threat multiplier” because it has the potential to exacerbate many of the challenges we are dealing with today – from infectious disease to terrorism. We are already beginning to see some of these impacts.
Santorum, however, knows better. So when Pope Francis recently said, regarding the damage we are dong to the environment,
We are Custodians of Creation. But when we exploit Creation we destroy the sign of God’s love for us, in destroying Creation … is sin! … Safeguard Creation. Because if we destroy Creation, Creation will destroy us! Never forget this!
(and there’s more to come; the pope is expected to release a strong statement on climate change in an encyclical by June 18)
Santorum felt it his duty to put His Holiness straight, by reminding him that
the church has gotten it wrong a few times on science, and I think that we probably are better off leaving science to the scientists and focusing on what we’re really good at, which is … theology and morality.
So there you have it. Santorum can denounce climate science as a leftist conspiracy. But the Church made a fool of itself over Galileo, so it should leave science to the scientists, and should therefore ignore what those same scientists say about the most pressing problem of our time.
One unexpected critic of Santorum’s position is Chris Wallace of Fox News Sunday, who reminded him that the Pope really does have a science qualification, and that 80-90 percent of scientists agree that humans contribute to climate change. [Actually, Wallace inflated the Pope’s diploma to a degree, and it’s more like 97% if we consider the scientists best placed to judge, but by Fox’s standards these are minor details].
Wallace: If he shouldn’t talk about it, should you?
Santorum: We have to make public policy with regard to the environmental policy. Whether we like it or not, people in government have to make decisions with respect to our public policy that affect American workers. The pope can talk about whatever he wants to talk about — I’m saying, what should the Pope use his moral authority for?
Wallace: He would say he’s protecting the Earth
Santorum: There are more pressing problems confronting the earth than climate change.
Such as Santorum’s Presidential bid, perhaps.
There is a scene in the BBC comedy Yes Minister, where a top civil servant is advising his Minister on how to react to a scientific report critcal of his policy.
Sir Humphrey, Civil Servant: Say there is debate among the scientists. Say more research is needed.
Jim Hacker, Minster for Adminstrative Affairs: But…
Sir Humphrey: I assure you, Minster, there is always debate among the scientists. And there is always a need for more research.
I do not know if Santorum has seen that episode, but when Wallace said that the science was settled, Santorum replied
Any time you hear a scientist say the science is settled, that’s political science, not real science, because no scientists in their right mind would say ever the science is settled.
One would like to be able to dismiss Santorum as lunatic fringe. Unfortunately, in the context of US presidential politics, he is nothing of the kind, as was can see from the following quotations, all from fellow-contenders for the 2016 Republican Presidential nomination.
Among these, Marco Rubio, Junior Senator for Florida, thinks we shouldn’t do anything about climate change because “all science deserves scepticism”. Rubio, incidentally, currently chairs the Senate Subcommittee on Oceans and the Atmosphere, responsible for climate data. Louisiana Governor Bobby Jindal, who does actually have a university degree that includes biology, signed into law the Louisiana Science Education Act, which, in the spirit of the Santorum Amendment, states that
the teaching of some scientific subjects, such as biological evolution, the chemical origins of life, global warming, and human cloning, can cause controversy, and that some teachers may be unsure of the expectations concerning how they should present information on such subjects
and extends permission to Louisiana’s teachers to
help students understand, analyze, critique, and review in an objective manner the scientific strengths and scientific weaknesses of existing scientific theories pertinent to the course being taught.
Those unfamiliar with US creationist tactics may not recognise what is really going on here, so let me spell it out. The Act allows teachers (and the school boards who employ them) to lie to children, by pretending that there are fundamental weaknesses in our understanding of evolution and global warming.
Mike Huckabee, former Governor of Arkasas, shows no such subtlety. In his own words,
I think schools also ought to be fair to all views. Because, frankly, Darwinism is not an established scientific fact. It is a theory of evolution, that’s why it’s called the theory of evolution. And I think that what I’d be concerned with is that it should be taught as one of the views that’s held by people. But it’s not the only view that’s held. And any time you teach one thing as that it’s the only thing, then I think that has a real problem to it.
As for climate change, Huckabee has attacked President Obama for saying that climate change is a more serious than terrorism, on the grounds that “a beheading is much worse than sunburn.” Huckabee, apparently, doesn’t know his carbon dioxide from a hole in the ozone. Nor do I expect him to notice the exceptional extreme heat in India, officially described as having killed over 2,300 people before the merciful arrival of last week’s monsoon.
Rick Perry, Governor of Texas, said in a 2011 newspaper interview
I am a firm believer in intelligent design as a matter of faith and intellect, and I believe it should be presented in schools alongside the theories of evolution.
As for the environment, he also said, earlier the same year,
There are a substantial number of scientists who have manipulated data so that they will have dollars rolling into their projects
and, more recently,
I don’t believe that we have the settled science by any sense of the imagination to stop that kind of economic opportunity…Calling CO2 a pollutant is doing a disservice the country, and I believe a disservice to the world.
And so on. Jeb Bush, former Florida Governor, says
I don’t think the science is clear what percentage is man-made and what percentage is natural. It’s convoluted. And for the people to say the science is decided on, this is just really arrogant, to be honest with you.
And what of Ted Cruz, another Texan. He chose to launch his campaign at Liberty University, an academic atrocity that I have written about before, where a course on “Origins” (i.e. Creationism) is compulsory. Liberty, incidentally, is the alma mater of Pam Stenzel, whom Scottish readers may remember for her sex-ed disinformation horror show. Anyway, here’s what Cruz has to say about global warming:
I’m a big believer that we should follow the science and follow the evidence. If you look at global warming alarmists, they don’t like to look at the actual facts and the data. The satellite data demonstrate that there has been no significant warming whatsoever for 17 years…. Today the global warming alarmists are the equivalent of the flat-earthers. You know it used to be: ‘It is accepted scientific wisdom the Earth is flat.’ And this heretic named Galileo was branded a denier.
We have come full circle, back to Galileo. Ted Cruz tells us that Galileo was condemned for denying that the Earth was flat. But the trial was In 1633, 141 years after Columbus had sailed to America, 111 years after Magellan’s expedition completed the first circumnavigation of the globe, more than 1800 years after Eratosthenes had correctly calculated the Earth’s radius from the difference in the length of noonday shadows between Alexandria and Aswan, and over two millennia since the roundness of the Earth had become common educated knowledge.
Ted Cruz is Chair of the Senate Subcommittee on Science. And like all the politicians quoted here he has managed to find backers willing to put up millions to help him become the next President of the United States, and, as such, responsible for negotiating the US position in climate negotiations. Be afraid, be very afraid.

One of the pleasures of blogging is finding like-minded people. Recently, I wrote about a fossil discovery in Calgary, and the piece was picked up by Miksha, who lives there. Now Miksha has provided some extra insights about the greatest of Scots geologists, Hutton, whom I, an adoptive Scot, have discussed before, and I am happy to be able to return the compliment. But I think Hutton would have said “expositor”, and for my money, Lyell is a close competitor for longwindedness.
James Hutton (1726-1797), Scotland’s most celebrated geologist, had a way with words. A rather awful way with words. But his scientific brilliance is uncontested. He is credited with moving geology away from the La-Z-Boy recliners of seventeenth century drawing rooms and onto the craggy cliffs where rocks are actually found. Until Hutton, gentleman-geologists were often preachers with parishes and parsonages to tend. They seldom ventured into the hills to study geology. If they collected rocks at all, it was the pretty ones they displayed in their cabinets. Such men philosophized about geology, Creation, and The Flood. They kept their fingernails clean. After Hutton, geology became the stuff of adventurers, travelers, experimenters, and above all, men and women with picks and hammers. Hutton was the founder of modern geology. He spurned divine intervention as the…
