Reef fish vanish during marine heatwaves, but may bounce back quickly on reefs that have few other environmental stressors.
While most corals turn ghostly white when they bleach, some turn neon purple. Scientists were baffled – until now.
Restoring the reef represents one of the most significant science and technology challenges in the history of nature conservation.
We might need to ignore climate change right now if only to save our sanity, but it certainly hasn’t been ignoring us.
Coral bleaching last summer was severe and widespread. And for the first time, severe bleaching has struck all three regions of the Great Barrier Reef.
From a scientific perspective, the results are fascinating and world-first. From a personal perspective, what I saw will stay with me for a long time.
Australia says the reef's world heritage values are fine and the threats are in hand. But the reality is far different.
Few feel the pain of the Great Barrier Reef's decline more acutely than the scientists trying to save it. Ahead of a UN climate summit, two researchers write of their grief, and hope.
It’s official. The outlook for the Great Barrier Reef has been downgraded to “very poor”, and the window to act is closing.
In the days before scuba technology, the celebrated photographer sought to capture the beauty of the reef by placing corals in an aquarium and shooting them. But under stress, they released algae.
Corals, mangroves and seagrass habitats have been affected by extreme weather events, and some may never recover.
Severe coral bleaching may have been the crucial factor in bringing home the reality of climate change for many people.
The Western Australian coral reefs may not be as well known as the Great Barrier Reef, but they're just as large and diverse. And they too have been devastated by cyclones and coral bleaching.
A new study found shallow water corals with high temperature tolerance in their DNA. Could they make reefs more resilient to climate change?
After repeated bleaching in 2016 and 2017 corals on the Great Barrier Reef are producing far fewer offspring.
Marine heatwaves have caused coral bleaching in one of the most isolated ecosystems in the world.
As the mid-winter break draws crowds to beaches, tourists may be wondering if their sunscreen is toxic to coral reefs.
Despite bans around the world, there's no empirical evidence sunscreens cause coral bleaching.
A coral biologist sampled corals from the most remote reaches of the Indo-Pacific and discovered that all of them show signs of stress.
Field samples, satellite measurements and isotopic data have shed new light on corals' eating habits.
