New scientific studies reveal coral reefs are facing severe pressure from global warming and ocean acidification, posing a 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, affecting hundreds of millions of people reliant 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, exceeding the thermal tipping point of 1.2C that coral reefs can withstand.
The second Global Tipping Points report, produced by over 160 scientists in 23 countries, warns that if the trend is not reversed, coral reefs worldwide will be lost.
The 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.
