Coral die-off marks first climate ‘tipping point’

Coral Die-Off Marks First Climate 'Tipping Point'

A report by 160 researchers from 23 countries concludes that the Earth has reached its first catastrophic tipping point linked to greenhouse gas emissions, with coral reefs in 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 report 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 report comes ahead of the COP30 climate summit in Brazil.

Author summary: Coral reefs face irreversible die-off due to climate change.
