What it does

Reef Watch pulls live data from the Coral Stress API and plots every monitored reef station on an interactive 3D globe. Each dot is colored by thermal stress level.

Stress levels

Color	Level	Meaning
🟢 #00e5a0	No Stress	Reef is healthy
🟡 #f5c842	Bleach Watch	Temps elevated, monitor closely
🟠 #ff7c2a	Bleach Alert 1	Active bleaching likely
🔴 #ff2d55	Bleach Alert 2	Severe bleaching underway
🔴 #ff0066	Critical	Mortality risk

Why it matters

50% of the world's coral reefs have disappeared since the 1950s. The ones that remain are under accelerating thermal stress from climate change. ReefWatch makes that crisis visible in real time, for anyone.
