Australia Research: Climate Change makes the Grand Barrier Reef Coral Whitening

Xinhua News Agency Sydney November 6 (Liu Shiyue) Australian James Cook University and other institutions researchers published papers in the American "Contemporary Biology" Half Monthly Purchase, over the past 20 years, climate change and the resulting seawater warming The castle reef has caused serious hazards, only about 2% of the big borough reef coral during this period can avoid whitening.

The color of the coral is from the symbiotic algae in its body. The seaweed will decrease when water temperature is increased or the acid is changed, and the coral gradually turns into white.

If the environment can’t be recovered, corals will die.

The first author, James Cook University Australian Research Council Coral Reef Research Demonstration Center, Terry Hughes, said to Xinhua News Agency, they use the Great Barrier Reef 1998, 2002, 2016, 2017 and 2020 5 times The relevant data of large-scale white-changing events has been evaluated after evaluating the location, degree of cerebral reefs, and since only about 2% of the big borough reef corals have "escap" since 1998. The study also found that in 2016, about 80% of the Grand Barrier Reefs were severely whiteized in 2017 and 2020.

Compared with the corals previously undergoing sea water, the corals without such experiences will be more fragile when they are boosted.

Researchers say that the various interference factors brought about climate change will interact, so it is often difficult to predict the impact of corals according to a single event.

The Great Barrier Reef is the general name of a series of coral island reefs outside the Northeast of Australia. It is the world’s largest coral reef group, more than 2,000 kilometers, a home for more than 1,500 fish. (Editor: Wang Yu, Yang Mu) Sharing let more people see.
