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)….

Study of the Arctic Pliocene will reveal clues to climate change today and into the future

Study of Pliocene Arctic Yields Insights into Climate Change Today, and for the Future

The mean monthly average concentration of carbon dioxide in the atmosphere as measured at NOAA’s Earth System Research Laboratory at Mauna Loa, Hawaii exceeded 400 parts per million (ppm) for the first time in modern history back in May. The last time atmospheric CO2 reached this level was during the Pliocene Epoch some 3 million to 5 million years ago,…

50 Million Year Old Fossil Clams Shed Light on El Nino and Global Warming

One current climate theory suggests that global warming could result in El Nino conditions becoming permanent as opposed to occurring in prevailing two- to seven-year cycles. New research based on a study of a long-lived species of fossilized clam that lived of the coast of Antarctica indicates that was not the case during the early Eocene, when the Earth was as warm as it’s been in the last 65 million years.
