Australia’s Great Barrier Reef will survive if warming kept to 1.5 degrees

A study released on Friday by an Australian university looking at multiple catastrophes hitting the Great Barrier Reef has found for the first time that only 2% of its area has escaped bleaching since 1998, then the world's hottest year on record. If global warming is kept to 1.5 degrees, the maximum rise in average global temperature that was the focus of the COP26 United Nations climate conference, the mix of corals on the Barrier Reef will change but it could still thrive, said the study's lead author Professor Terry Hughes, of the Australian Research Council's Centre of Excellence for Coral Reef Studies. "If we can hold global warming to 1.5 degrees global average warming then I think we'll still have a vibrant Great Barrier Reef," he said. Bleaching is a stress response ...

Study shows 14% of the world's coral on reefs was already lost between 2009 and 2018 The world's coral reefs are under attack by climate change and more will disappear if oceans keep warming, according to a report released Tuesday. The study by the Global Coral Reef Monitoring Network (GCRMN), a U.N.-supported global data network, showed that 14% of the world's coral on reefs was already lost between 2009 and 2018, equal to about 11,700 square kilometers, an area 2.5 times the size of Grand Canyon National Park.

During some summers, as the Caribbean water temperatures climb, the luminous coral colonies of gold, green and blue that ring the island nation of Cuba give way to patches of skeletal white. The technicolor streaks of darting tropical fish flash less frequently. The rasping sounds of lobsters go quiet. While Cuba’s marine life has suffered from overfishing and pollution, there is mounting evidence that the warming of waters due to climate change may be taking a large toll as well -- both off the island’s coast and globally. A view of a coral colony on the coast of Havana, Cuba, March 28, 2021.
