"The researchers drilled down 700 meters through rock and sludge to retrieve sediments deposited during the Pliocene Warm Period, 3.5 to 4.5 million years ago.“Evidence from the Pliocene Warm Period is relevant to studies of current climate change because it was the last time in our Earth’s history when global temperatures were higher than today,” Ravelo said.Carbon dioxide levels during the Pliocene Warm Period were also comparable to levels today, and average temperatures were a few degrees higher, I’m sure the Warmistas will try to spin this that the CO2 caused the warming, but who was burning all the oil and driving SUVs then? Hmmm? Oh, and there is the little problem of the 800 year lag between warming and when the CO2 shows up… So to me it’s pretty dramatic confirmation that CO2 levels NATURALLY were higher at the same time it NATURALLY was warmer; and the warmth drove the CO2 out of the ocean just as the gas laws predict.And it all happened with NO human intervention as the only “people” around then were more like smart chimpanzees than modern humans.
