World has lost 14% of its coral reefs to bleaching from global warming

collected data from more than 300 scientists from 73 countries, including South Africa, over a span of 40 years, including two-million individual observations, for the report, the largest analysis of coral reef health ever undertaken.

Large-scale coral bleaching events caused by elevated sea surface temperatures are the greatest threat to their survival. “Bleaching can be thought of as the ocean’s version of the canary in the coral mine since it demonstrates coral’s sensitivity to dangerous and deadly conditions,” according to the report.

Fortunately for South Africa, Porter says, global warming driven by climate change has not yet caused any major coral bleaching or mortality events on the country’s reefs.

As Australia has shown, they recover.
