Brandon, you might like this twist,
Hidden power
From about 1950 to 1980, the cooling effects of aerosol particles in the atmosphere served to mask the warming effects of greenhouse gas emissions, the new thinking goes. Hurricane activity in the Atlantic was thus lower than it might otherwise have been during this period.
But since the 1980s, North America and Europe have reduced the amount of aerosols they pump into the atmosphere.
"Aerosols have had this masking, cooling impact for several decades, and now as we begin to clean up this atmosphere we may get something we didn't bargain for," Mann told LiveScience.
Without aerosols to offset the warming effect of greenhouse gases, waters in the Atlantic will continue to warm and hurricanes will continue to increase in intensity for decades to come, the researchers say.
"The assumption that the recent upturn in Atlantic Hurricane activity is due to a [natural] oscillation has been the basis of claims by the National Hurricane Center that what we're likely to see is just a temporary increase in hurricane activity for the next two decades," Mann said. "Our analysis suggests that this is simply not the case."
Hurricane season begins June 1, and researchers predict another above-normal year of activity.
