Clues from the ancient past can help predict abrupt climate change

Journal Reference: Peter O. Hopcroft, Paul J. Valdes. Paleoclimate-conditioning reveals a North Africa land–atmosphere tipping point. Proceedings of the National Academy of Sciences, 2021; 118 (45): e2108783118 DOI: 10.1073/pnas.2108783118 Current understanding of tipping points, in which the climate system exceeds a threshold beyond which large and often irreversible changes occur, is limited. This is because … Read more
