Research Finds Carbon Dating Flawed 625
eldavojohn writes "New research funded by the National Science Foundation at the University of Miami is showing that carbon dating (the 13C/12C ratio used to infer age) in the ocean can only be trusted up to 150 million years ago. From the primary researcher, 'This study is a major step in terms of rethinking how geologists interpret variations in the 13C/12C ratio throughout Earth's history. If the approach does not work over the past 10 million years, then why would it work during older time periods? As a consequence of our findings, changes in 13C/12C records need to be reevaluated, conclusions regarding changes in the reservoirs of carbon will have to be reassessed, and some of the widely-held ideas regarding the elevation of CO2 during specific periods of the Earth's geological history will have to be adjusted.' While this research doesn't necessarily throw carbon dating out the window, it should cause people to rethink so many theories about early life that revolved around ages of sediment in the oceans."

Sorry, that doesn't follow. Yes everything is moving apart, which means that the average density of the observable universe is decreasing, but that has nothing to do with the total mass. For example, I could give you a solid block of lead weighing say 1000lbs, that would be a small-ish object, maybe about 1 cubic foot (I'm just giving some example numbers). Then I could melt it and re-form it into a honeycomb structure that contained lots of gaps and was, say, 10 foot across. It has gotten bigger, but the mass hasn't increased!
While it is possible that some physical 'constants' are actually changing value in time, there are lots of experiments in this area and there are quite rigorous bounds that show that, if there is any variation, it is on time-scales of ~ billions of years, and of no consequence to carbon dating methods. For example, if there was some changing physical constant that caused nuclear decay rates to change over time, then this would change in the rate of nuclear fusion in the sun (which depends on the same physics as nuclear decay), and this would be observable in astronomical observations of distant stars. In fact, that no such effect is seen is one of the experiments that puts a bound on how fast the physical constants can be changing over time.
There may also be some biological reasons why the C12/C13 ratios in particular, could change in time. But this would be due to changes in biology as species have evolved, not changes in the underlying physical laws. The ratios of C12 and C13 retained by plants is determined by things like climate and moisture. Both of these isotopes are stable, it is just the slightly different sizes and masses cause them to act slightly differently in chemical reactions. This has nothing to do with radioactive decay (which is C14 radiocarbon dating, which is based on the notion that unstable radioactive C14 is made in the upper atmosphere by cosmic ray collisions, so while a plant is living it absorbs some fraction of C14 from the atmosphere, and this stops when the plant dies. So by seeing how much of the C14 has decayed into a stable atom [into nitrogen-14 in fact] and how much of it remains, you can determine how long ago the plant died.)

What effect does the Industrial Revolution and the subsequent history's use of fossil fuels have on carbon dating?
Interesting question.
It would have no effect on anything already old and dead. It wouldn't really have any effect on normal uses of carbon dating. What the Industrial Revolution and burning fossil fuels has done is taken large amounts of "old" C14-depleted carbon out of the ground and dumped it into the atmosphere as CO2. Radiation hitting the upper atmosphere slowly turns some of that carbon into "fresh" radioactive C14. However I believe it takes several thousands of years for that conversion to C14 to really rise to its full level. So this means that for a few thousand years the carbon in the air is going to be somewhat C14 depleted - it reads as "old" in carbon dating. Plants will consume that "old" carbon CO2 from the air and photosynthesize it into the sugars and starches and proteins and everything else that makes up the plant. This should have the effect of dead modern plants testing as probably a few hundred years older than they actually are. It will have the same effect on animals - the plants eat "old" carbon from the air and then the animals eat the "old" carbon from the plants. The animals build their bodies out of that "old" carbon in their food.
So the effect will likely be maybe a few hundred year shift in the apparent readings for materials from this general era, but carbon dating readings will be calibrated against the expected results to take that effect into account. Future archaeologists may have trouble telling the difference between 1700's materials and 2000's materials. They may read about the same.
My estimates may be off on the size of the effect, but that is how carbon dating works and that is approximately the sort of impact it should have.

God made the old law because Man 'deserved' it, being Satan-fodder. Man was unique, having free-will. Man was also special, being made in God's image. Man did bad things which God had granted license for Man to do under penalty. God enforced these penalties to improve Man.

Occam's razor is not an embargo against the positing of any kind of entity, or a recommendation of the simplest theory come what may[11] (Note that simplest theory is something like "only I exist" or "nothing exists"). Simpler theories are preferable other things being equal.
"Other things being equal." This is often applicable, but is a big stretch in this particular situation. Since we are making our guess about the existence or non-existence of God independent of any significant evidence (one side can say "autogenesis, things evolved, no God", the other can say "God made everything, everything is the way it is because God made it that way", both sides' explanations can fit the evidence equally well (regardless of whether or not one is actually a theory)), we must resort to philosophical arguments. This is where Occam's Razor is often abused as some sort of scientific law. It's not, it is purely philosophical and statistical. As said in wikipedia, it is only truly applicable "other things being equal." However, to say that all things are equal on both sides is ludicrous. There are massive philosophical ramifications for either guess, and any attempt to effectively weigh them all in a manner agreeable even with most people is surely doomed to failure.
My point here is that the existence or non-existence of creation is not a matter that can be settled scientifically, as much as we would all like.

There are minor activist groups dedicated to both sides of the issue, but as far as National or International organizations dedicated to science or particular fields of science, non-biased organizations that incidentally issues position statements on the issue as an incidental action aside from their actual mission of preforming and promoting other science, every single one has come down on the side of confirming the scientific legitimacy of evolution and categorizing the anti-evolution side as invalid or pseudo science.

Yes, sadly. However there is still some light amidst all the heat. I personally have completely won over a few converts to the evolution side. There are many many people convinced evolution==atheism or somesuch, people who rant against evolution with no interest in mutually discussing and honestly considering each other's evidence on the subject, and of course conversations with them go nowhere. However I have also had people come in asserting some doubts, challenges, questions against evolution and honestly examining the response. And such people are inevitably amazed by the examples of science and evidence that exist backing up evolution. People saying wow, I didn't know all that was out there. People suddenly coming to a very strong decision about which side is grossly guilty of pushing false claims.
Just to cite a single example and to squeezed it down to a single sentence, there is a chunk of the fossil record that is completely continuous and gap-free showing the intermediate forms spanning thousands of species - a chunk of evidence which is pretty well sufficient all by itself to establish the validity of evolution beyond any reasonable doubt.

Radiocarbon dating is a radiometric dating method that uses the naturally occurring radioisotope carbon-14 (14C) to determine the age of carbonaceous materials up to about 60,000 years...

Carbon dating is based on the decay rate of Carbon 14, and has a pretty short limit geologically speaking - 70,000 years with enrichment methods, but closer to 50,000 years using traditional counting. It's possible accelerator 14C dating has pushed this slightly - I haven't worked in this field for about a decade.
The tie-in to "dating" in this context is that sediments are deposited over time, and if they're undisturbed you can drill a core that'll give you (theoretically) a record of the 13C/12C ratio over time - but that ratio is not being used for dating AT ALL. The only way you could use the ratio for ersatz dating is if the sediment shows an annual 13C/12C cycle due to annual temperature variations - then you can count the cycles the same way you can count tree rings (BTW 13C/12C in tree rings varies in this same sort of summer/winter - or spring/fall - pattern). In any case, the actual dating of the sediments is usually done using a different, longer-lived, radiometric isotope ration such as you find with rubidium-strontium (That particular isotope pair may not be the best fit for sea sediments; like I said, I've been out of this for a while. We mainly did 13C/12C in trees and 18O/16O in ice cores).

Basically, what they say they found was that this is only trustworthy in deep ocean sediments, not on land or in island sediments, and you can only find deep ocean sediments for the last 150 million years or so, due to plate tectonics recycling the sea floor.
This will not affect geological dating at all. It may affect the interpretation of some work regarding, e.g., extinction events. It's hard to say without looking in detail at the other work (they may have several lines of evidence, etc.).
