Great Barrier Reef Hit By Bleaching For The Second Year In A Row

[Dulcinea]

For the second consecutive year, aerial surveys show severe coral bleaching in the Great Barrier Reef off the coast of Australia.

While severe bleaching events have occurred three other times in the past 20 years — in 1998, 2002 and 2016 — this year marks the first time it's known to have happened two years in a row. Scientists say the damage is caused by higher water temperatures due to global warming.
