CO2 smashing extreme weather records

You've said before how stupid it is to be posting these individual records all the time. It's the overall stats that count.

But seeing as it seems you can't help yourself:

Johannesburg tightens water controls as record drought persists

Greater Bank, along with its employees and customers, has raised almost $109,000 to help farming families across the New England region as they battle with the ongoing reality caused by the worst drought on record.

We could go on.

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.

And you, jantimot:
A warm atmosphere holds more water. When its cold there is more moisture to precipitate out as snow.
It's not surprising to me that when we get cold snowy weather it's heavier snow. That doesn't mean there is a trend to more snow overall, just it tends to be heavier when we get it. Similar to the situation with rainfall.

After a very quick skim I don't see anything in those references you've posted that contradicts that.

And yes we still have winters, so we still expect cold spells. We just expect more hotter spells and records and fewer colder ones overall. Which the evidence is showing.

But as the IPCC states, you will still get occasional very cold spells. You still get 1/100 year events and those will still tend to be very cold when they are cold events. And once in a blue moon you will get 1/500 year natural variability events that will still be doozies. But overall you'd expect those cold extremes to average slightly less cold overall, relative to historical records, over time, as the planet warms
