Tornadoes are caused by warm and cold air coming together. If the air was warmer there would be no drastic disturbance. Last April when the atmosphere was about 1 degree warmer we had had very few tornadoes. This year the air mass coming in from the North and meeting with the air mass coming from the South is cooler. Thus more of a disturbance. The earth is cooling not warming...
Top Climate Scientist on Tornadoes: 'Irresponsible Not to Mention Climate Change'
In the opinion of top climate scientist Dr. Kevin Trenberth, it's "irresponsible not to mention climate change" in the context of the killer tornadoes this week in the South.
It is irresponsible not to mention climate change. ... The environment in which all of these storms and the tornadoes are occurring has changed from human influences (global warming). Tornadoes come from thunderstorms in a wind shear environment. This occurs east of the Rockies more than anywhere else in the world. The wind shear is from southerly (SE, S or SW) flow from the Gulf overlaid by westerlies aloft that have come over the Rockies. That wind shear can be converted to rotation. The basic driver of thunderstorms is the instability in the atmosphere: warm moist air at low levels with drier air aloft. With global warming the low level air is warm and moister and there is more energy available to fuel all of these storms and increase the buoyancy of the air so that thunderstorms are strong. There is no clear research on changes in shear related to global warming. On average the low level air is 1 deg F and 4 percent moister than in the 1970s.
