Hurricane Threats

Severe tropical cyclones (called hurricanes in the North Atlantic and northeast Pacific) can cause loss of human lives and serious economic damage. In his Perspective, Bengtsson charts the current knowledge about how hurricanes form and whether long-term trends can be discerned in the past century or predicted for a future warmer planet. He also discusses the report by Goldenberg et al., who have analyzed hurricane activity in the North Atlantic and the Caribbean over much of the past century.
