Holy shit how are you this dumbYou're missing the point. The whole point of climate change is that the polls are warming the fastest. Thus, the temperature delta between the polls and the equator is shrinking. If that's the case, bad weather will decrease. The entire Earth could warm 20 degrees more allowing more moisture in the air, but without the very cold air that comes from the polls, you will not get severe weather.
Climate always changes. There is zero evidence we are causing it to change more.
