^^^ this (the appallingly-bad weather in the northern hemisphere, obviously including North America, the British Isles and northern Europe) is
all to do with the
North Atlantic Oscillation. I pointed this out, nearly five years ago, here on the forum. I'm intrigued (in a multivalent Fortean way) that the mainstream media are NOT reminding the muggles, proles & normies about this....

The North Atlantic Oscillation Index appears currently-consistent with possessing a large index value (ie the pressure differential between the 'permanent' Icelandic low, and Azores high. And what kind of weather do you think that gives us, north of the 'roaring forties'?
(Think of these systems as being eternal invisible rotating cogs of wind/weather (& partly oceanic waters), the word 'gyre' (yes, as in The Jabberwocky) is associated with these global gearwheels).
Yes....
Wikipedia- NAO said:
Westerly winds blowing across the Atlantic bring moist air into Europe. In years when westerlies are strong, summers are cool, winters are mild and rain is frequent
This, dispassionately, describes our northern hemisphere weather patterns all-too-accurately, at present.
There is also the closely-related Arctic Oscillation, again discussed upthread:

I suspect this 'AO' is now running in a more prolapsed/ unconstrained mode, drooping below 60deg North.....
I'm going to do something that I may subsequently regret, and that is join-up some dots on a oblate spheroid.... we're all only too well-aware of the appaling bush fires in Australia over the last few months.
My simplistic understanding of basal global climate systems is that the southern hemisphere can be considered to be the, well, polar opposite of the north. Our northern winter is the antipodean summer, due primarily to the Earth's axial tilt.
I assumed that there would be an equivalent of the Arctic Oscillation, and not-too-challengingly guessed what its name would be, in advance of searching for it: and hey presto: the AAO
https://en.m.wikipedia.org/wiki/Antarctic_oscillation
Now: I became too confident in my mirror-image guesswork, and presumed there might be such a thing as a South Atlantic Oscillation (and indeed there may well be such a thing, albeit unremarked/named or discovered).
The equivalent predominant influencers in the southern hemisphere seem actually to be the
Pacific_decadal_oscillation
(or PDO) and also the South Pacific Oscillation.
I wonder if there is a similar set of affective Oscillation Indices in the southern hemisphere, matching & mirroring those here in the north? If so, I've also not heard any mention of this within news reports of the hot pyrogenic weather in Australia (so: if you're an Australasian, please comment as to whether or not there's been any mention of such a correlation being identified).
A further aspect of all of this semi-informed supposition: and although I'm sociologically-forbidden from saying this, I'm going to say it anyway....
It cannot be said with absolute certainty whether the root cause of global climate change is JUST man-made, or that there are OTHER forces majeure in constant influential play such as solar (eg coronal mass ejections/ extended sunspot effects) and/or geogenic factors (including volcanic particulate and gaseous atmospheric transfer).
(viz...sunspots in the context of
The Solar Cycle : and I do accept that the increase from 1700 could mainly represent the emergence of observational data)
But
irrespective of what the actual main causitive effect is (ie man-made, natural, or...the most-likely situation in my opinion, which is >both<).....have I half-wittingly crystallised what the 'global climate emergency' actually is?
Or have I simply put into some flawed sentences a fractured summary of what must already be known by the climate scientists of the world?
