A new report by 160 researchers warns that failing to limit global warming to 1.5℃ is pushing humanity towards a 'danger zone', with coral reefs facing irreversible damage. Led by Professor Tim Lenton, the study emphasizes the need for immediate action from global leaders, as current climate goals are insufficient. It highlights the risks of further climate tipping points, including potential sea-level rise and biodiversity loss, and calls for halving greenhouse gas emissions by 2030 and reaching net zero by 2050.
