Tropical cyclones across the globe, except Atlantic hurricanes, are moving closer to land in recent decades, a new study found. Also called typhoons, tropical cyclones generally have been moving westward by about 18 miles per decade (30 kilometers) since 1982, putting them closer to land and coastal populations, a study in Thursday’s journal Science said. Each decade since the 1980s, an additional two cyclones have come within 124 miles (200 kilometers) of land, the study said. Researchers don’t quite know why this is happening, although natural climate variation could explain some of what’s being observed. And while the new study found storms are getting closer to land, researchers still haven’t seen a significant increase in landfalls, which “is still a puzzle,” said study lead author Shuai Wang, a cyclone scientist at Imperial College in London. “It’s not only the landfall that causes damage. When the cyclone is close enough to …
