The Relationship between Extreme Global Warming and Earth’s Past Mass Extinction Events – International Business Times

Present issues with global warming mirror conditions in past mass extinction events which happened millions of years ago.

Climate scientists study the underlying causes behind previous mass extinction events to gain a better understanding of what may happen due to existing amounts of greenhouse gas emissions and rising global temperatures.

It’s been speculated that if all fossil fuels are burned up until the 22nd century, global temperatures will rise by as much as 10 degree Celsius. If that happens, it would be similar to what occurred during the Paleocene/Eocene Thermal Maximum (PETM) event in the Cenozoic era.
