Half of Reef-Building Corals Now Face Elevated Extinction Risk

AI Insight

A comprehensive assessment published in Nature reveals that nearly 50% of reef-building coral species face an elevated relative risk of extinction. This finding represents a significant increase in threatened coral species compared to previous evaluations, reflecting accelerating pressures from climate change, ocean warming, and acidification on coral reef ecosystems. The study provides updated extinction risk assessments for scleractinian corals, which form the structural foundation of coral reef habitats worldwide.

Why it matters

Coral reefs support approximately 25% of all marine species and provide essential ecosystem services including coastal protection, fisheries support, and tourism revenue for hundreds of millions of people. The findings underscore the urgent need for enhanced conservation strategies and climate action to prevent catastrophic loss of reef biodiversity and the collapse of reef-dependent ecosystems and human communities.
