Global Warming Kills 14 percent of Corals Worldwide
Global warming helped wipe out 14 percent of the world’s coral reefs between 2009 and 2018, the largest-ever survey of coral health has found, warning that more of the vibrant underwater ecosystems were likely to die if oceans warm further.
Corals in South Asia and the Pacific, around the Arabian Peninsula, and off the coast of Australia, were the hardest hit, according to the report which was released on Tuesday, compiled by more than 300 scientists in the Global Coral Reef Monitoring Network.
The report spanned data for 40 years, 73 countries and 12,000 sites and found the total area destroyed equal to about 11,700 square kilometres (4,517 square miles).
Besides anchoring marine ecosystems, they also provide food, protection from storms and shoreline erosion and jobs for hundreds of millions of people worldwide. The study looked at 10 coral reef-bearing regions around the world and found that reef loss was mainly the result of coral bleaching, but also overfishing, unsustainable coastal development and declining water quality.
