Climate Change Is Destroying The Corals On The Great Barrier Reef
The Great Barrier Reef, one of the seven wonders of the natural world, is at its greatest risk ever of disappearing into the annals of man-made disasters, due to mass coral bleaching caused by climate change. “Human-caused climate change” is causing an “utter tragedy” to one of the world's largest coral reef systems, according to two Australian researchers. The current bout of coral bleaching on the Reef, “the third in just five years”, is the “most severe and the most widespread” ever. “Coral bleaching at regional scales is caused by spikes in sea temperatures during unusually hot summers,” say Terry Hughes and Morgan Pratchett. Both are professors at James Cook University’s research centre for coral reef studies in tropical northeastern Australia. “We surveyed 1,036 reefs from the air during the last two weeks in March, to measure the extent and severity of coral bleaching throughout the Barrier Reef region.” The results are “not a pretty picture”. Mass bleaching has hit the enti...
