Australian scientists say shading reef and controlling coral-eating starfish can only be effective if strong action is taken to reduce emissions

Shading corals and deploying more heat-resistant species across the Great Barrier Reef on an as-yet untested scale could buy the world heritage site another two decades, according to a study led by Australian government scientists.

The scientists said combining “life support” interventions such as cloud brightening – which involves spraying sea water to make low-altitude clouds more reflective – with better management of a coral-eating starfish could help delay “precipitous declines” caused by global heating.
