Global Coral Bleaching Hits Record Levels as Global Warming Exceeds 1.2°C | Planet Pulse | N18G

Global warming is pushing the planet into uncharted danger. Scientists warn that warm-water coral reefs—the rainforests of the sea—have crossed a critical thermal tipping point. From 2023 to 2025, the world witnessed the worst coral bleaching event on record, with 84% of reefs across 82 countries under extreme heat stress. Coral reefs are vital, supporting a quarter of all marine species and nearly a billion people who rely on them for food, income, and coastal protection. Experts say even limiting warming to 1.5°C may not save these ecosystems. Urgent global action is needed at COP30 to prevent irreversible damage.
