Australia’s Great Barrier Reef has lost more than half of its corals since 1995 due to warmer seas driven by climate change, a study has found. Scientists found all types of corals had suffered a decline across the world’s largest reef system. The steepest falls came after mass bleaching events in 2016 and 2017.

Can dead coral be revived?
It turns out that some corals only look dead when exposed to unusually warm water. They discovered that seemingly dead corals can in fact regrow in the wake of heat damage caused by climate change. Some made an almost full recovery.

Fearing Their Kids Will Inherit Dead Coral Reefs, Scientists Are Urging Bold Action. Scientists expect increasing marine heat waves to cause coral bleaching, which can result in reefs dying off.
What is killing coral reefs?
Despite their importance, warming waters, pollution, ocean acidification, overfishing, and physical destruction are killing coral reefs around the world. Genetics is also becoming a larger area of coral research, giving scientists hope they might one day restore reefs with more heat tolerant coral.
Why are reefs dying?
Coral reefs are dying around the world. Damaging activities include coral mining, pollution (organic and non-organic), overfishing, blast fishing, the digging of canals and access into islands and bays. Climate change, such as warming temperatures, causes coral bleaching, which if severe kills the coral.
