‘Concerning': Marine heatwaves increasing, especially near Australia

Marine heatwaves are increasing in their frequency and duration at an accelerating rate in many parts of the world, especially around Australia, a team of international scientists has found.
Warm waters may be welcomed by beachgoers but
the impacts beneath the waves are not so good.
The number of oceanic heatwave days a year has increased by 54 per cent in the past century globally, the researchers determined, using data of sea-surface temperatures from long-established sites and satellites.

“We have seen an increasing trend in the frequency and duration [of marine heatwaves], and that trend has accelerated in the past 30 years or so," said Lisa Alexander, associate professor at University of NSW's Climate Change Research Centre, and an author of the paper published in Nature Communications on Wednesday.
