Scientists: Climate change poses bleaching risk to Australian coral reefs
Now, a new study offsite linkshows changing climate and warmer ocean temperatures might increase coral bleaching in Australia’s Great Barrier Reef offsite linkmore than previously thought.
The study, co-authored by scientists with Australia’s James Cook University, University of Queensland and NOAA’s Coral Reef Watch program, examined 27 years of NOAA satellite data for sea surface temperatures.
Scientists found that, in the past, when corals were exposed to a short pulse of higher — but not too high — water temperatures, they became more tolerant to bleaching. However, climate change predictions show water temperatures increasing to levels that would erase this protective pulse, leading to more severe bleaching.
