Climate: August 2021


Scientists at the University of Southampton have discovered that extensive chains of volcanoes have been responsible for both emitting and then removing atmospheric carbon dioxide (CO2) over geological time. This stabilised temperatures at Earth's surface.

Two hundred fifty-two million years ago, much of life on planet Earth was dying. In an event that marked the end of the Permian period, more than 96 percent of the planet's marine species and 70 percent of its terrestrial life suddenly went extinct. It was the largest extinction in Earth's history.

New research led by the University of Bristol demonstrates that a decline in the concentration of atmospheric CO2 played a major role in driving Earth's climate from a warm greenhouse into a cold icehouse world around 34 million years ago. This transition could be partly reversed in the next centuries due to the anthropogenic rise in CO2.
