Annual marine heatwave days have increased by 54 per cent from 1925 to 2016, accelerating since 1982. Between 1925‒1954 and 1987‒2016, marine-heatwave frequency increased globally by 34 per cent and lasted 17 per cent longer. Researchers attribute this to a global increase in mean ocean temperatures and suggest that we can expect a continued global increase in marine heatwaves in the future.
