Hurricane Threats

Abstract
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][1] 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 .][2], who have analyzed hurricane activity in the North Atlantic and the Caribbean over much of the past century.
