Worsening ocean heat waves are 'supercharging' hurricane damage, study finds

Phys · · 776 words · By Seth Borenstein

A study published in Science Advances finds that marine heat waves are intensifying hurricanes and tropical cyclones, leading to more frequent and severe disasters. Researchers analyzed 1,600 storms since 1981 and found that those crossing warm ocean areas caused 60% more billion-dollar disasters. The study links rising ocean temperatures to increased hurricane damage and warns of growing risks for coastal regions.
