This is a very important point because it's very commonly believed that extreme cold weather (99 pct) will be worsened, and it's central to Scott Alexander's piece. Not storms per se, just the inverse to heat waves. Can anyone find any evidence for this from primary sources like the IPCC? My guess is the answer is that they're going to reduced. If they're virtually certain that 75th percentile events will be reduced that usually suggests that 99th percentile events will be reduced too.
