Range of radiocarbon dating gets a boost

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.

For this method to work, the rate of production of carbon-14 in the atmosphere has to remain constant through time.

In truth, however, the amount of carbon-14 in the atmosphere varies with fluctuations in solar activity and Earth's magnetic field, changes in atmospheric conditions and even the exploding of atomic bombs!

"Fancy statistical treatments" that didn't even resolve all of the discrepancies?

This book was written on the basis of the calibration that intcal has been developing for over 20 years, a process that has unfolded in the stages listed above. In an article titled "Radiocarbon Daters Tune Up Their Time Machine," magazine explained: "[T]hanks to new and more accurate data from foraminifers, corals, and other sources - plus some fancy statistical treatments that help predict which way data gaps bend the curve - the intcal group has been able to resolve most of the discrepancies.And what was it that finally got the scientists to agree on their uncertain calibration curve? The problem with all these theories and conclusions is that they hark back to the scientists' blind belief in the false theory of evolution.That is about the only thing the scientists agree on, yet it causes much confusion and chaos.intcal extended radiocarbon dates beyond the limit of dendrochronology by basing it on "matched uranium series and radiocarbon dates on fossil corals, coupled with radiocarbon-dated organic material from laminated marine sediments in the Cariaco Basin, Venzuela" (Mike Walker, ). They apparently increased the effectiveness of radiocarbon dating by basing their calibration charts on radiocarbon-dated coral and sediment layers!That is circular reasoning - defending the method by using the very same method!
