What do we know about global warming in terms of positive effects? Not much, as the possible consequences anticipated a range of negative effects on a global scale, such as the melting of the ice that will lead to the rise of the sea level, or the apparition of extreme weather phenomena, such as drought or flooding.

But two South Florida scientists think otherwise, and revealed that there is a positive side to it, at least for the United States: no more hurricanes. And they bring arguments to that: as the surfaces of the oceans tend to increase temperature, the development of the hurricanes will be suppressed by an increased vertical wind shear in the Atlantic Ocean near the United States.

Researchers at the National Oceanic and Atmospheric Administration in Miami and the University of Miami conducted the study using information that dates back to the middle of the 19th century according to which the number of hurricanes tended to decrease as the global oceans warmed up. The findings will be published in the Geophysical Research Letters scientific journal later today.

It is not the first time scientists draw attention on the increasing wind shear due to warmer oceans, but at the same time, they come to contradict several opposite conclusions that highlight the fact that tropical systems are likely to suffer an increase in number and duration.

This is an unusual study, critics say, as it focuses exclusively on the hurricanes that hit the U.S. coast, which account for a small part of the total number of hurricanes around the globe, so it is impossible to project the consequences to a global scale based on that. At the same time, they say the study focused on data the Nobel Prize award winners rejected when conducting a study on climate changes.
