On the other hand it some think that the general climate may become less violent. This is because the Polar Regions will warm up more than the equator. A large portion of the weather cycle is driven by the flow of heat to the Polar Regions of the earth. So during the ice ages it is likely that there were stronger storms particularly blizzards.
In addition it is not a one to one relationship. When we have an El Nino pattern of warmer water on the surface of the pacific there are actually fewer hurricanes.
Now don't get the idea that I am a global warming denier or that we should not do anything to reduce the impact of global warming. However I do think that it will not be the end of the world. It seems to be a feature of every age that people declare that we are on the edge of disaster. That things are only getting worse and worse in the world.
I think ultimately what global warming will be is a change. Some places will gain, and some will lose out. Nothing stays the same, and while this is scary we cannot stop it. We must learn to live with the fact that nothing is permanent.
