Global Warming to Fuel More Severe Tornadoes and Thunderstorms

No, it won't. The temperature rise has been in the higher rather than lower latitudes and in nighttime rather than daytime temperatures. The severity of a thunderstorm depends to a large degree on the temperature difference between cold and warm air masses. If the more northerly colder, drier air masses are progressively less cold, then the difference between them and the more southerly warmer, humid air masses is less pronounced, meaning a reduced chance for violent thnuderstorms and tornados.

[Cletus.D.Yokel]

Well, that consider that tornadoes and thunderstorms are the result of ^weather^, not ^climate^.
