NOAA shows major global coral bleaching
Earlier this year NOAA mentioned the possibility of a major coral bleaching during 2015.
As shown in the animation by NOAA, the prediction turned out to be true and a global coral bleaching event is in progress.
Due to the effects of El Niño, sea surface temperatures are higher than normal causing heat stress and bleaching of corals in many regions.
According to NOAA, the Hawaiian Islands are facing the biggest threats, with an intensification of bleaching estimated for at least another month.
This strong El Niño unfortunately might cause global bleaching again over the course of 2016.
More information on the spread of global coral bleaching is available with the NOAA Coral Reef Watch Program.
