Abrupt Climate Shifts Change the Latitudes of Storm Activity
A new 6500-year construction of storms combined with other paleo-storm records finds abrupt changes in the Atlantic Ocean circulation impact the latitudinal preference of storm activity.

As the Planet Warms, Intense Storms Become More Common
Thirty-nine years of satellite data reveal that the prevalence of intense hurricanes, cyclones, and typhoons—category 3 and above on the Saffir-Simpson scale—is increasing.
