Executive Summary
Warm-water coral reefs have crossed a climate tipping point as marine heatwaves drive severe bleaching, mortality, and growing risks to coastal economies
- Warm-water coral reefs have passed a thermal tipping point linked to rising ocean temperatures
- The 2014 to 2017 global bleaching event damaged more than half of the worlds reefs
- More than 80 percent of reefs in over 80 countries have faced extreme heat since January 2023
- Bleaching is worsened by acidification, overfishing, pollution, and coastal development
- Reef decline threatens fisheries, tourism, biodiversity, and natural coastal protection
- Scientists say local management and restoration can help, but global emissions cuts are critical
- The report warns other tipping risks include Amazon dieback, ice sheet collapse, and AMOC weakening
Quick Facts
- What: Coral reefs have crossed a thermal tipping point
- Where: Warm-water reefs across tropical oceans worldwide
- Why: Ocean heat and related stressors are driving bleaching and mortality
- Who: More than 160 to 200 climate scientists and reef researchers
- When: Current warming near 1.4C with worsening damage since 2023
