More Tas marine heatwaves likely: study

global warming

An unprecedented marine heatwave off Tasmania's east coast was almost certainly caused by global warming and more extreme events are on the way, scientists warn.

Temperatures in waters off the state's east coast peaked at nearly three degrees above average in the summer of 2015/16, causing an outbreak of Pacific Oyster Mortality Syndrome and poor salmon farming performance.

"We can say with 99 per cent confidence that anthropogenic climate change made this marine heatwave several times more likely, and there's an increasing probability of such extreme events in the future," Dr Eric Oliver, lead author of the study published in international journal Nature Communications, said.
