Reported by 2 outlets · first reported Oct 22, 8:00 AM ET

In its first global assessment of coral reefs, the IUCN classified 96% of reef systems across 80 countries as critically endangered, at high risk of ecosystem collapse before 2075 because of global heating. The assessment includes Australia's Great Barrier Reef, and scientists described the findings as a wake-up call.

Why it matters

Reefs support fisheries, coastal protection and tourism for hundreds of millions of people.
