Global Coral Reef Crisis: Over 84% Under Heat Stress as Ocean Temperatures Soar

Coral reefs are enduring their most widespread bleaching event on record, with over 84% of global reef areas under serious heat stress. Triggered by record-high ocean temperatures in 2024, this crisis affects reefs in 82 countries. Without algae, corals lose their color and can die, threatening marine biodiversity and coastal communities. Experts emphasize that the only lasting solution is cutting emissions to curb ocean warming. Immediate action is crucial to protect these vital ecosystems.
