COP31

Climate Action Tracker warns the world is heading for an irrevocable overshoot of global temperature limits, with 2.7C of warming expected by 2100.

COP31 has opened in Antalya, Turkey, with the UN warning that climate action is far too slow and urging leaders to turn promises into results.

Scientists told BBC News that 2026 is on course to be the hottest year on record as COP31 opens in Turkey, driven by climate change and El Nino.
