The risk of a hothouse Earth trajectoryEarth’s #climate is now departing from the stable conditions that supported human civilization for millennia. Crossing critical temperature thresholds may trigger self-reinforcing #feedbacks and tipping dynamics that amplify warming and destabilize distant #Earth system components. Uncertain tipping thresholds make precaution essential, as crossing them could commit the planet to a #hothouse trajectory with long-lasting and potentially irreversible consequences.https://www.cell.com/one-earth/fulltext/S2590-3322(25)00391-4?_returnURL=https%3A%2F%2Flinkinghub.elsevier.com%2Fretrieve%2Fpii%2FS2590332225003914%3Fshowall%3Dtrue#ClimateScience #ClimateCrisis #TippingPoint #HothouseEarth
