The ice age could cause a sudden death in quite a bit of plants and animals, possibly making the intake of carbon-14 smaller. Therefore, fossils from that time era and after would have less carbon-14 to change.
Irrelevant. 14C dating depends on ratios, so the amount of intake doesn't matter. An organism's intake of 14C per atom of 12C depends only on the 14C/12C ratio in the atmosphere.
Also, if your mechanism did affect 14C dating, we would see a jump in the calibration curves. We don't see that jump. Your mechanism is falsified.
It's the
agreement between different and independent dating methods that scares YECs more than anything else. There's a thread around here specifically for discussing that agreement,
Age Correlations and an Old Earth: Version 1 No 3 (formerly Part III). See you there?
In 1958 Hessel de Vries showed that the concentration of carbon-14 in the atmosphere varies with time and locality.
When you copy something from another site, you should give a proper attribution. From
Radiocarbon dating
quote:
In 1958 Hessel de Vries showed that the concentration of carbon-14 in the atmosphere varies with time and locality. For the most accurate work, these variations are compensated by means of calibration curves. When these curves are used, their accuracy and shape are the factors that determine the accuracy and age obtained for a given sample.
So,the issue you raised was answered in the sentence after the one you copied.
For the most accurate work we compensate for the variations; but even if we ignore the variations the technique is accurate enough to disprove YEC claims about the age of the universe and life.
