Maldives suffering worst coral bleaching since 1998

Coral bleaching is caused when rising water temperatures stress the coral, leading it to expel the algae it uses to obtain nutrients. When water temperatures rise even slightly, algae leaves the coral polyp and enters the water column, causing the coral to lose its colour and eventually die.

Reports of bleaching have been trickling in from marine biologists and researchers across the country.

Hussein Zahir from the Marine Research Centre (MRC) has been collecting reports of the bleaching, and said that based on his estimates, “10-15 percent of shallow reef coral is now completely white, while 50-70 percent has begun to pale.”
