..... asked what to study if he wanted to investigate creationism versus evolution. I advised continuing physics and chemistry and avoid having to learn flawed theories as paradigms. So, predictably, I was challenged to expose some of them. I choose for the problems in the 100,000 "ice age" cycle and continue that here. So there we go. The ice ages are usually explained as a result of difference in solar radiation due to Milankovitch cycles in the Earths orbit. We think we see those cycles back in sea sediment cores like the compiled benthic stack, the reaction of miniscule ocean bottom dwelling "benthic foraminifera" on climate on the surface. However this graph are indicates some problems with that idea, explained by Richard Muller here and more scientifically here.. In short, we have work to do.
