1974 was the record year for violent tornadoes year prior to 2011. It was also the peak year of the global cooling panic.

UAH data shows 2011 temps still below 1979-98 average (and of course well below last year). Temperatures have actually dropped in the last 2 weeks at a time of year when you would actually expect them to be rising.

This certainly does seem to be the case. Here in SE Kansas, we’ve had an unusually cool May……holding our breath on the prospects of more tornado activity tonight.
I pointed the graph out on WUWT in that we got fewer strong tornadoes during the warming spell. Maybe it’s heating up in the US. 😉
