Scientists confirm historic massive flood in climate change

Scientists from NASA and Columbia University, New York, have used computer modeling to successfully reproduce an abrupt climate change that took place 8,200 years ago. At that time, the beginning of the current warm period, climate changes were caused by a massive flood of freshwater into the North Atlantic Ocean.

This work is the first to consistently recreate the event by computer modeling, and the first time that the model results have been confirmed by comparison to the climate record, which includes such things as ice core and tree ring data. ”

We only have one example of how the climate reacts to changes, the past,” said Gavin A. Schmidt, a NASA Goddard Institute for Space Studies (GISS), New York, researcher and co-author on the study. “If we’re going to accurately simulate the Earth’s future, we need to be able to replicate past events. This was a real test of the model’s skill.”
