   Why the huge increase in days with #ExtremeHeat?

   Climate change does two things to air temperature:
   1. The AVERAGE shifts to higher temperature. This one is obvious. But also:
   2. The VARIANCE gets larger so the extremes become more prevalent

   Both of these effects together give a LOT more VERY hot days.
