I can't be bothered to argue with you Dave.* These arguments are becoming pointless, tedious and repetitive. Four trawls the Internet in pursuit of biased pieces and you conveniently overlook his inaccurate statements or try misguidedly to endorse them.
Putting words into people's mouths doesn't mean that's what is being said. I appreciate it helps your personal construct to believe that severe events are a major issue but it's just your position and not reality.**
Fact: global warming is the major threat***
Fact: severe weather is not caused solely by the clash of different airmasses****
Fact: there will still be significant temperature contrasts in a warmer world.
There's little merit in trying to defend a piece that is so clearly flawed & even less merit in trying to defend Four's typically biased comment. As for pedantic, you have the gold medal in that....

Please sort yourself out.
**Wrong again. There are lots of instances where it has been argued by 'the convinced' that more extreme weather is to be expected from AGW - and discussed many times in this forum, where I and others have said that more extremes of weather also, goes with a more meridional jetstream. Check out your climate history. More extremes of weather, because of AGW, has been pushed by the political wing of 'the convinced' to a large extent - this is not my construct. I have just responded as Four and others have done. This is not to say that there isn't, with AGW, more energy in the system - just that it's the greater contrast or difference in air mass characteristics that leads to more extreme weather and a more meridional jetstream gives much more opportunity for this to happen. Higher temperatures are a serious threat, but a part of the picture where other drivers that lead to more extreme weather events, cannot be ignored.
*** As associated with sea level rise - yes. **** Agreed - I have just said as much.
With regard to your last 'fact' - yes again, but on the major scale, the IPCC forecasts are for the polar regions to warm most which means overall less temperature contrasts and therefore, in my book, less cyclogenesis. Warming in itself will mean changes in circulation patterns and shifts in climate zones as well as sea level rise.
You mention Four seeking out bias pieces: The piece Four mentioned was the research - this wasn't bias was it? It's a pity but typical, that you choose to ignore the paper, which was the essence of his post - here - and concentrate on a loose detail of his combative post.
I'll put aside, atm, your more personal innuendos.
