Tornadoes, extreme weather, and climate change

Tornadoes, extreme weather, and climate change

Best info we have on the relationship between a warmer world and severe convective storms that can produce tornadoes is in the 2008 Synthesis and Assessment Report of the US Global Change Research Program. Chapter three of that Weather and Climate Extremes Assessment indicates that several studies do show that environmental conditions favorable for convection are more likely with more greenhouse gases, but results are not conclusive. We now have improved resolution models running at our Oak Ridge Supercomputer thanks to the Stimulus funding. We may be able to make more definitive statements (one way or the other)after these get analyzed over the next few years. Meanwhile, we know that La Nina years tend to have a greater chance of severe outbreaks. So as usual, there are natural factors that have to be considered, and any human made factors would be confounded within these...
