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

Coral Reefs Under Threat from Climate Warming

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

According to recent research, warm-water coral reefs have crossed a critical tipping point due to global heating, resulting in accelerated death rates from repeated mass bleaching events. This impacts hundreds of millions of people who rely on coral reefs 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 coral reefs, estimated to be 1.2C of warming.

The second Global Tipping Points report, released on Monday, warns that if the trend is not reversed, coral reefs worldwide will be lost. The report was produced by over 160 scientists in 23 countries, led by the Global Systems Institute at the UK’s University of Exeter.
