Three tornadoes that killed at least 90 people in 1953 led to speculation that atmospheric tests of nuclear weapons caused them.
But the speculation has been one-sided, with talk of human influences on tornadoes following disasters, but little about whether human influences have acted as a brake on their numbers after anomalously low activity....As a result, there is not much we can say about long-term patterns, except that the annual average count of all but the weakest tornadoes has not changed for more than half a century. Also, the timing of the tornado season hasn't changed...
Equally clear is that those who continue to talk in certain terms of a future blighted by more severe tornadoes as a result of climate change are failing to heed all the available evidence.
