As coral reefs get hit by climate warming, ocean protection rises up political agenda

Climate Warming Impact on Coral Reefs

New scientific studies reveal that coral reefs are under severe pressure from global warming and ocean acidification, posing a significant threat to marine life.

According to recent research, warm-water coral reefs have crossed a tipping point due to global heating and are dying at an accelerated rate. This is attributed to repeated mass bleaching events, affecting hundreds of millions of people who rely 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 around the world will be lost, warns the second Global Tipping Points report, released by over 160 scientists in 23 countries, led by the Global Systems Institute at the UK’s University of Exeter.
