Studies show that ocean warming in the Great Barrier Reef has killed half the coral


A recent study has found that half of the coral has been destroyed by sea warming in Australia’s Great Barrier Reef.

the studyPublished in the Proceedings of the Royal Society B Wednesday’s London magazine, included four Australian researchers who counted the coral abundance in the three decades beginning in 1995.

Researchers found that “the abundance of large colonies on the crest” dropped to 98 percent, while the coral on the southern slope increased by a modest 25 percent.

Unusually warm sea temperatures caused all sizes, almost all species and in shallow and deep climates, co-author, Terry Hughes. The washington post.

Hughes, a professor at the ARC Center of Excellence for Coral Reef Studies in Queensland, said branching and table-size coral were “the worst affected” during record high temperatures in 2016 and 2017.

“We hope to continue this fall,” Hughes said. “The only effective way to improve results for coral reefs is global action on greenhouse gases. If the global temperature rises to 3 or 4 [degrees Celsius]The reef will not be unfamiliar, so there is no time to lose. ”

Andreas Dietzell, another co-author and professor at the ARC Center, told the Post that the coral’s recovery rate is going “very slowly” and not with the destruction.

Dietzel stated, “Corals are tremendously resilient because of their ability to produce millions of babies, but they / we desperately need a break.”

Gabby Ahmadia, director of oceanography at the World Wildlife Fund, told the newspaper that some are establishing resistance to coral warming, providing some hope. But he said, “Many people say that by 2050 coral loss will be 90 percent.”

The Great Barrier Reef serves as a tourist draw for Queensland.

The Sydney Institute of Marine Science and the University of Sydney are working to brighten the sea cloud in an effort to block sunlight and prevent further warming of the coral. Experts said the action may not be enough as Australia is one of the largest coal exporters, the Post said.
