I'm hoping some YECs participate here, especially foreveryoung who has claimed to have an answer to the heat problem (in Message 36).
You forgot to read the rest of his post though.
What changed it for me was how radiometric dates matched exactly with isotope ratios for climate related extinction events. I am doing a term paper on the "sixth great extinction" in a class called paleobiology. In going over the various opinions of scientists on the causes of the past 5 great extinctions, measurements of particular radioisotopes that are related to climate and are a proxy for conditions that are thought to be causes of extinction, I came to the conclusion that things fit like a hand in glove with the radiometric dates. You cannot accelerate things like climate proxies in isotope ratios. Two separate phenomena that could not possibly influence one another were in such PRECISE agreement, I could not possibly maintain my position any further without a total denial of reality.
