Global warming destroyed 14 percent of the world’s corals in more than a decade: Study

The biggest study conducted by researchers found that global warming has wiped out 14 percent of the world’s coral reefs from 2009 to 2018. Along with global warming, destructive fishing and pollution also contributed to the loss of 14% of precious corals in the world.

The largest-ever coral health survey has found that the globe lost around 11,700 sq km of coral in total. If there occurs further warming in the ocean, then it is expected that more underwater ecosystems would get affected and might die in the future.

The title of the report is “Status of Coral Reefs of the World: 2020″ and is based on nearly two million data points gathered from 12,000 sites in 73 countries, spanning over 40 years. It’s the first survey of its kind since 2008 and the sixth global survey of its kind.

Meanwhile, the study also found that Reef algae growing under coral pressure increased by 20% between 2010 and 2019. The report by the Global Coral Reef Monitoring Network, compared every part of underwater coral build parts with that of currently available ones.

“Climate change is the biggest threat to the world’s reefs,” co-author Paul Hardisty, the chief executive of the Australian Institute of Marine Science, said in a statement. Sea surface temperatures that occur due to the absorption of greenhouse gas emissions by the ocean became the cause for the leading coral loss. The major coral bleaching event in 1998 resulted in the big loss of 8% of the world’s coral.

The change over time has been determined with the healthy live coral with algae-infested areas and according to over 300 scientists, coral reefs in South Asia and the Pacific, the Arabian Peninsula, and off the coast of Australia were the hardest hit. 

However, Scientists discovered that in spite of the pressures on reefs, many were strong and could recover under the proper circumstances, mainly if quick action to prevent global warming was done. Apart from global warming, overfishing, irresponsible coastal development, and deteriorating water quality are some of the other threats to coral.
