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.
Australian scientists confirm the mass bleaching, yet are hopeful the world's largest coral reef ecosystem can recover.
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.
