Climate change is heating oceans faster than the world's coral reefs can handle. So scientists are breeding corals that can withstand hotter temperatures – but only to a point.
Coral reefs face a dire future as oceans get hotter. Scientists are breeding corals that can handle heat better, in the hope they can survive long enough for humans to rein in climate change.
Hotter temperatures are threatening coral reefs worldwide. Now, scientists are pinpointing how some "super corals" are better able to withstand the heat.
Australia's environment minister says her government will urge against the U.N. adding the Great Barrier Reef to a list of endangered sites, saying worries are a reflection of the previous government.
While higher water temperatures led to a coral bleaching event in some areas in March, the temperatures did not climb high enough to kill the coral, according to the Australian government.
Some corals have turned a ghostly white due to extreme heat stress. It's the fourth bleaching event on the Great Barrier Reef in the last seven years, which makes it harder to recover.
