CO2 smashing extreme weather records, page-53

“And we probably should also remember that heavy snowfall is a symptom of a warmer wetter atmosphere, when it strikes cold temperatures.  So your record may well have been a symptom of greenhouse gas warming of the atmosphere.”

Well, not according to the settled science.

No uncertainty given for the decrease in cold extremes,  ...... but on page 60 they give a slight qualification:

“It is virtually certain that there will be more frequent hot and fewer cold temperature extremes over most land areas on daily and seasonal timescales, as global mean surface temperature increases. It is very likely that heat waves will occur with a higher frequency and longer duration. Occasional cold winter extremes will continue to occur. {WGI SPM E.1, 12.4.3}”

I don’t consider a northern hemisphere early whiteout occasional cold winter extremes. But, when I check WGI SPM E.1, 12.4.3 I see:

 “It is virtually certain that there will be more frequent hot and fewer cold temperature extremes over most land areas on daily and seasonal timescales as global mean temperatures increase. It is very likely that heat waves will occur with a higher frequency and duration. Occasional cold winter extremes will continue to occur (see Table SPM.1). {12.4}”

and table one says says nothing about “Occasional cold winter extremes will continue to occur“

And you call this science? It’s no more than guesswork.
