Coral die-off marks first climate ‘tipping point’

Coral Die-Off: The First Climate Tipping Point

A report by 160 researchers from 23 countries concludes that the Earth has reached its first catastrophic tipping point due to greenhouse gas emissions, with coral reefs experiencing an almost irreversible die-off.

Unless we return to global mean surface temperatures of 1.2C … we will not retain warm-water reefs on our planet at any meaningful scale

The Global Tipping Points report by the University of Exeter states that coral reefs hit a tipping point when warming reaches between 1C and 1.5C above 19th century temperatures, with global heating currently at about 1.4C.

This news comes ahead of the COP30 climate summit in Brazil.
