In the evolutionary uniformitarian (slow-and-gradual) view of earth’s history, the earth’s climate remained on a fairly even keel for hundreds of millions of years. However, it is claimed that there were some dramatic exceptions. Around 80 million years ago, the planet’s temperature supposedly plummeted, along with carbon dioxide levels in the atmosphere. The earth is said to have eventually recovered from that cooling event, only to swing back into the present-day Ice Age 50 million years ago.To read the rest of this very moving topic, click on "Did Tectonic Activity Trigger the Ice Age?"
That’s right! You did read that correctly. Evolutionary uniformitarian geologists are saying we are still currently in an Ice Age! Perhaps you didn’t realize that when you sweated through the heat and humidity of the summer months and were told that the soaring temperatures were due to global warming or climate change!
Now geologists at the Massachusetts Institute of Technology claim to have identified the likely cause of both the cooling event at 80 million years ago, and the onset of the Ice Age around 50 million years ago, as well as a natural mechanism for carbon sequestration. Evidently, just prior to both periods, massive tectonic collisions took place near the earth’s equator—a tropical zone where rocks undergo heavy weathering due to frequent rain and other environmental conditions. This weathering involves chemical reactions that absorb a large amount of carbon dioxide from the atmosphere. The dramatic drawdown of carbon dioxide cooled the atmosphere, they suggest, and set the planet up for the cooling event at 80 million years ago and the Ice Age beginning 50 million years ago, in the late Cretaceous and the Eocene, respectively.
