Does clean air make hurricanes worse?

Kerry Emanuel, a Massachusetts Institute of Technology climatologist, and Michael Mann of Pennsylvania State University, contend that the aerosol particles, which reflect sunlight and cool the atmosphere, have been masking the effect of global warming on Atlantic Ocean hurricanes for several decades. The researchers say that it is only in recent decades, as aerosol emissions from North America and Europe have declined due to clean air standards, that the full impact of greenhouse gas emissions on hurricane strength has been realized.

So it seems we have a choice : to smother or bake.

Any day now, I expect to hear of ads funded by Mobile/Exxon saying that aerosol emissions from cars are "life".
