Warming coastal waters emerge as primary driver of large-scale humid heat waves

Rising sea surface temperatures in coastal waters are driving 50 to 64 percent of the increase in large-scale humid heat waves, according to new research. The study, from researchers at the Potsdam Institute for Climate Impact Research (PIK), Princeton University and Sun Yat-sen University, implies that coastal sea surface temperatures could be a potential early warning indicator for widespread humid heat extremes. The paper is published in the journal Nature Geoscience.
