However much temperature is increasing, I find the frequency of extreme weather events far more problematic. How many 100/500/1000 year storms has the United States dealt with over the past few years? Even more to the point, is it possible that the rate at which these extreme weather events is increasing is also increasing? Without getting into the weeds about particular numbers, it's known that given a global temperature increase, the poles experience the majority of that change. One reason the United States has experienced so much extreme weather of late is because the northern hemisphere polar jet stream has gotten a lot more erratic, in large part because of a declining temperature delta between the north pole and its adjacent temperature bands.
