What used to be a rare one-two punch of consecutive hurricanes hitting about the same place in the United States weeks apart seems to be happening more often, and a new study says climate change will make back-to-back storms more frequent and nastier in the future.
Using computer simulations, scientists at Princeton University calculate that the deadly storm duet that used to happen once every few decades could happen every two or three years as the world warms from the burning of coal, oil and natural gas, according to a study in Monday’s Nature Climate Change.
The reason isn’t storm paths or anything like that. It’s based on storms getting wetter and stronger from climate change as numerous studies predict, along with sea levels rising.
Louisiana and Florida residents have already felt it. In 2021, major Hurricane Ida blasted Louisiana with 150 mph winds. Just 15 days later a weakening Nicholas came nearby, close enough for its wind, rain and storm surge to add to the problems, said study co-author Ning Lin, a risk engineer and climate scientist at Princeton. Her study looked at not just the storms but the problems back-to-back hurricanes caused to people.
