New Research Reveals Climate Warming 55 MYA was Geologically Instantaneous

New research into past changes in climate indicates that global warming can take place much more suddenly than previously thought – over the course of only about 13 years. Temperatures at high latitudes rose as much as 8ºC (14ºF) and oceans warmed from surface to bottom some 55 million years ago during what’s known as the Paleocene-Eocene Thermal Maximum (PETM)….
