More coral bleaching feared for Great Barrier Reef in coming months

The next event, if it occurs, may not be as damaging as the previous two, but could ruin the chances of coral recovery

The Great Barrier Reef could face more bleaching in the coming months, following unprecedented mass bleaching events in 2016 and 2017, which are believed to have killed half the coral.

Forecasts stretching to February are pushing the science to its limits, leaving significant uncertainty. But scientists say there is reason to be concerned, and some bleaching is very likely, although it won't be anything like what happened during the past two years.
