World’s coral scientists warn action is needed now to save even a few reefs from climate change

We saw damage almost everywhere, from the Bahamas to the Great Barrier Reef.

Corals can become stressed when temperatures around them rise just 1˚C (1.8˚F) above their tolerance level. With water temperature elevated from global warming, even a minor heat wave can become devastating.

If global temperatures rise by 2˚C (3.6˚F) or more, only about 1% will still exist.
