A fresh analysis of a historic ice core has revealed evidence of a much smaller ice cap.
Reactive gases like ozone are hard to preserve, but clumped isotopes and models provide clues to past ozone and suggest a global increase in wildfire at megafaunal extinction.
New research attributes a shift to longer, stronger glacial cycles to increased friction between ice sheets and bedrock in the Northern Hemisphere 1 million years ago.
The impacts of the Antarctic Ice Sheet response to climate change will have global consequences for millions living near the coast. It’s just a matter of when.
Sea level changes have repeatedly reshaped the Paleo-Agulhas Plain, a now submerged region off the coast of South Africa that once teemed with plants, animals, and human hunter–gatherers.
Interglacials provide insights into the impacts of warmer than present conditions in certain regions of Earth.
Researchers identified 11 different interglacial periods over the past 800,000 years, but the interglacial period we are experiencing now may last an exceptionally long time.
