Marine heat waves are supercharging the damage caused by hurricanes and tropical cyclones across the globe. In Friday’s study researchers look at 1,600 landfalling storms in 41 years, the rapid intensification of those cyclones and the damage they cause especially when they go over big, long-lasting ocean hot spots. Those that go over marine heat waves are 60% more likely to cause at least $1 billion in damage. Hurricanes Helene, Milton and Otis are good examples. Marine heat waves are worsening because of climate change. Researchers say forecasters and government officials need to keep this in mind during future storm threats.
