FEWER tornado are a sign of man-made climate change, as are seasons where the number of tornado is about average. Get with the program buddy. You sound like some kind of denier.
More tornadoes, less tornadoes.
More snow, less snow.
More hurricanes, less hurricanes.
More Flight MH370 airplanes missing, less missing.
More trash in the Indian Ocean, less trash in the Indian Ocean.
All caused by global warming, er, I mean climate change.
