Human-induced climate change was almost certainly responsible for a marine heat wave off Tasmania’s east coast that lasted 251 days and had an area of impact seven times the size of the island, a new study shows.
Climate change was almost certainly responsible for a marine heatwave off Tasmania’s east coast in 2015/16 that lasted 251 days and at its greatest extent had an area of impact seven times the size of Tasmania, according to a new study published today in Nature Communications.
The marine heat wave reduced the productivity of Tasmanian salmon fisheries, led to a rise in Blacklip abalone mortality, sparked an outbreak of Pacific Oyster Mortality Syndrome and saw new fish species move into Tasmanian waters.
At its peak intensity, waters off Tasmania were 2.9°C above expected summertime temperatures.
