More than a third of the coral in the northern and central parts of Australia's Great Barrier Reef is dead, say researchers. The damage is part of an event triggered by global warming and the El Nino weather phenomenon.
The world's largest coral reef system has witnessed massive coral bleaching caused by rises in water temperatures and ocean acidity levels. Now, the Australian government is planning to breed more resilient coral.
Nearly a third of coral in the Great Barrier Reef died during a nine-month period in 2016. The die-off was caused by high sea temperatures.
As water temperatures rise and ocean acidity levels increase, corals are dying off at record rates. Now, researchers believe they may be able to prevent coral bleaching in parts of the world's largest coral reef system.
Researchers in Australia are turning to cloud-brightening technology in a bid to save the Great Barrier Reef. But they warn it will only buy time, and we must reduce carbon emissions.
