New scientific studies reveal that coral reefs are under severe pressure from global warming and ocean acidification, posing a significant threat to marine life.
Warm-water coral reefs have crossed a tipping point due to global heating, dying at an accelerated rate from repeated mass bleaching events. This affects hundreds of millions of people relying on them for fishing, tourism, and protection from rising seas and storm surges.
Global average temperatures are about 1.3-1.4C above pre-industrial times, which is higher than coral reefs can withstand.
The thermal tipping point for coral reefs is estimated to be 1.2C of warming. If the trend is not reversed, coral reefs worldwide will be lost, according to the second Global Tipping Points report, produced by over 160 scientists in 23 countries.
A recent report, led by the Global Systems Institute at the UK’s University of Exeter, highlights the urgent need for ocean protection to rise up the political agenda.
