If corals are going to survive on today's ecologically stressed reefs, they've gotta be tough. Scientists have therefore been developing a special "turbo-charged" coral, which has recently been found to be reproducing on the Great Barrier Reef.

In a world first, researchers have conducted a cloud-brightening trial as a way of protecting fragile corals in Australia's Great Barrier Reef, to see whether reflecting some of the Sun’s energy away could help limit damage due to climate change.

Recent severe bleaching events to strike the Great Barrier Reef have led to widespread death of the corals making up world’s largest living structure, but scientists are coming up with increasingly inventive ways to repair the damage.

We've recently seen a number of proposals for protecting coral reefs from the dangers of climate change, and now it turns out that corals already have a self-defense mechanism. They can release aerosols into the atmosphere to create a protective "cloud umbrella."
