The Great Maya Reef: a 1,126-km barrier system off Mexico, Belize, Guatemala and Honduras
The IUCN has classified 96% of the world’s shallow-water coral reef systems as critically endangered and warned of possible ecosystem collapse by 2075 if current warming continues. The assessment, presented at COP17, blames heat stress from climate change and adds that reefs still show pockets of resilience that stronger emissions cuts and local conservation can protect.
