The 2025 Global Tipping Points Report, published by the University of Exeter and Stockholm Resilience Centre, indicates that the world has already crossed the first climate tipping point involving the widespread mortality of warm-water coral reefs on which nearly one billion people and a quarter of all marine life depend. Caused by rising ocean temperatures, acidification, overfishing and pollution, this massive damage to coral reefs is expected to continue unless global warming is reversed.

The 2025 World Meteorological Organization Global Annual to Decadal Climate Update also predicts that a 2.7° F warming threshold will be reached within the next five years, which will result in more frequent and extreme weather events, disruptions in food production, limited water access and a rise in sea levels. Compiled by 160 scientists from 23 countries, the report calls for urgent action to prevent further tipping points.
