Resumen de Want fewer hurricanes?: Pollute the air
A new analysis shows that the number of storms falls as pollution rises, and rises when pollution drops. Nick Dunstone of the Met Office Hadley Centre in Exeter, UK, says that tighter pollution controls could reduce aerosols so quickly that they'll have record numbers of tropical storms for the next decade or two. Aerosols cool Earth's surface by scattering light which does not affect storms. But aerosols also increase the brightness and lifetime of low-level marine clouds. When he added this to his climate models, the simulated clouds cooled the surface more than expected.
