Guardian: It may come as a surprise to learn that we are in the middle of the third great coral bleaching event in human history. And scientists are calling it the severest yet. The last great bleaching event was in 1998 when 11% of the worlds coral reef coverage was lost. Some areas like the Maldives lost as much as 90% of their reefs. This event is worse, possibly much worse. 38% of the planets reefs will be affected, with 12,000 sq km of reefs killed off entirely according to experts.
