Great Barrier Reef bleaching could accelerate by 2034

Australia’s Great Barrier Reef, the world’s largest coral reef system, could suffer a bleaching event every two years by 2034 under the current level of greenhouse gas pollution, according to a study published on Thursday.

“Limiting temperature rise above pre-industrial levels to no more than 1.5 degrees Celsius is critical for the survival of reefs worldwide,” said the report published by the Climate Council, reports Efe news. According to the study, 70% of coral reefs will be at risk of long-term degradation by 2100, if the global temperature rises by 1.5 degrees Celsius above pre-industrial levels.

An increase in global temperature of 2 degrees Celsius above pre-industrial levels would put 99% of the corals at risk. The experts also indicated that the two consecutive coral bleaching events on the Reef in 2016 and 2017 have led to mass coral mortality.IANS
