Australia | Great Barrier Reef Marine Park may be on verge of another reef-killing bleaching spate

Parts of the Great Barrier Reef are showing signs of heat stress, raising the risk of another major coral bleaching event, scientists from the Great Barrier Reef Marine Park Authority have announced. Eastern Australia has experienced a long period of warmer than usual ocean currents, which has increased water temperatures across two-thirds of the reef 2 to 3 degrees Celsius above average for February, Reuters reported.

Scientists warned that if water temperatures do not drop in the next two weeks, the bleaching would likely become widespread. It would be Australia’s third major coral bleaching event in five years, with the others in 2016 and 2017.
