Over 60% of the world's coral reefs have been bleached in the last year

Newsdesk:

In a sobering warning about the growing threat to the world’s coral reefs, the US-based National Oceanic and Atmospheric Administration (NOAA) has revealed that nearly two-thirds of these important marine ecosystems experienced such severe heat stress  is that past bleaching has begun.
 The agency’s latest assessment indicates that a staggering 60.5% of the global reef area has been affected by the ongoing fourth mass bleaching event due to the mixed effects of climate change and the El Nino climate pattern.  This figure continues to surpass the effects of previous events in 1998, 2010 and 2014-2017.
