Read about history and pick out a good one for us

1953An F5 tornado hits Beecher, Michigan, killing 116, injuring 844, and destroying 340 homes...during global cooling.

1966   – Topeka, Kansas, is devastated by a tornado that registers as an "F5" on the Fujita scale: The first to exceed US$100 million in damages. Sixteen people are killed, hundreds more injured, and thousands of homes damaged or destroyed........during global cooling.

One of the benefits to the current climate optimum(from global warming) has been the decrease in violent tornadoes.


Recent Tornadoes are Due to Unusually Cold Weather

https://www.drroyspencer.com/wp-content/uploads/tornadoes-1954-2018.jpgAs has been pointed out elsewhere, a trend line fit to the number of strong to violent U.S. tornadoes has gone down from 60 in 1954 to 30 in 2018. In other words, the number of most damaging tornadoes has, on average, been cut in half since U.S. statistics started to be compiled.


metmike: This is totally expected based on the authentic science/laws of physics.

When you decrease the meridional temperature gradient(from less cold air at the highest latitudes) you have less energy potential to feed weather systems. You also weaken cold fronts and jet streams that contribute the most towards the high end tornado outbreaks(200+ mph winds for instance).

The incidence of weaker tornadoes have gone up a bit, however,  mainly because, in the 1990's, we installed tornado detecting NEXRAD DOPPLER radars across the country that can see and measure the wind, including in many weak tornadoes in rural settings that exist briefly, did not do much damage and went unreported previously with the old radar systems that did not detect them.

June 8, 1949,,,,, the book "1984" is published.

I see some similarities in our world today.
