Summary/Abstract
This study provides “a quantitative assessment on the role of global warming on marine heatwaves” using a “counterfactual version of observed global sea surface temperatures since 1940, corresponding to a stationary climate without the effect of long-term increasing global temperatures, and use it to calculate the contribution of global air temperature rise on the intensity and persistence of marine heatwaves.”
The study attributes an increase in frequency and intensity of extreme marine heat events to global warming.
