Great Barrier Reef
Australia's Great Barrier Reef is an enormous and spectacular natural wonder, but it is also one of the most devastating examples of ecosystems that are increasingly threatened by a warming world. Explore its diverse communities of marine wildlife, and discover the challenges facing corals — which are especially sensitive to temperature change — and the animals that depend on them.
A new study found that sea turtles born in areas most heated by climate change are 99.8 percent female.
Two-thirds of the length of the Great Barrier Reef is suffering from bleaching, a condition likely to cause mass coral die-offs.
More than 300,000 years ago, a behemoth undersea landslide sent huge amounts of debris sliding down the Great Barrier Reef, generating a 90-foot-high (27 meters) tsunami.
