From NOT A LOT OF PEOPLE KNOW THAT

You may recall the BBC’s recent attempt to blame the currently cold and wet summer on global warming!
Well the Met Office’s figures for July show that rainfall for the month was hardly unprecedented:
In reality, there is no such thins as “normal July weather”. It can veer from one extreme to another from one year to the next.
You don’t need to invoke the climate bogeyman to explain English weather.
“But June was the warmest on record! Cherry picking!!!!”
No it probably wasn’t. Stop referencing the bad surface data lol.
If they only used temperature stations with records going back 100 years, the data becomes much less scary. What’s the rationale for using a chart restricted to 50 plus years records?
“You don’t need to invoke the climate bogeyman to explain English weather.”
Or Scottish, Welsh and Irish weather.
It’s autumnal. No summer for you…. And yes it’s definitely global warming
“”Ulez just the start and similar scheme needed for buildings, experts warn
People assume that burning hydrogen is a clean process that produces only water vapour, but that is not the case””

They’re on a roll
“The Jet Stream became ‘stuck'”
Have you ever heard such childish nonsense – It’s straight from the mouth of The Chocolate Covered Cherub..
‘Oh Mummy, my hand got stuck in the cookie jar so I had to eat them all so as to get back out again’
What is entirely obvious (and I’m showing you my Tonga picture again to illustrate) is that they are confusing The Jet Stream with ordinary events within the Troposphere
The Jet Stream being the lowest latitude and lowest altitude manifestation of the Polar Vortex – where said vortex, existent in the Stratosphere, ‘meets’ or contacts the Troposphere.
It was completely unknown about until aircraft started flying high enough (in the 1930’s) and ‘odd things’ started happening with their (dead reckoning) navigation.
They found themselves arriving very early at their destination, or very late, or as in the famous case in the Andes, not arriving at all.
(Having descended into where the airport should have been but a 12,000ft mountain actually was. Dead reckoning told them they’d flown over the mountain and were safe to descend. The Jet Stream reckoned otherwise)
What these muppets are calling ‘The Jet Stream’ is what happening between the two red arrows I’ve drawn on this image of the synoptic chart for the Pacific so as to explain why Tonga got cold.
The wind speeds between my arrows will be nudging 3 figures, probably even near the surface and be greater at altitude.
To my mind and listening to them raving about The Jet Stream it’s entirely obvious they’re confusing (don’t know the difference) between what’s in my Tonga picture and what the Polar Vortex is about.
We’re all familiar with those sorts of short lived bursts of ‘jet’
They’re what makes everything from Dust Devils to tornados to anticyclones (Northern hemisphere) to hurricanes.
Or even when a forecaster appears on TV to tell us that ‘The wind will ‘gust’ to x mph’
Those ‘gusts’ are miniature jets
But just like children, they’ll say anything at any time in order to get their own way.
Meanwhile, The English Summer Joke….
England only has two seasons: Winter and July
Explain that please, Met Office
We do know what really got stuck don’t we = the heat dome over Europe.
And it got stuck there because and despite the high temeperures, there was/is No Serious Amount of Water in The Landscape of Europe any more.
The high temps would have evaoprated that water had it been there and because water vapour is sooooo bouyant relative to dry air it would have risen and ‘burst the heat dome’
But because there was no water (vapour) coming off Europe, cold air from aloft could descend and heat via the LapseRate FoehnEffect.
Building and reinforcing the dome.
That cold air is, what was, warm wet air coming from, surprise surprise, the UK. (and Netherlands, Denmark, Northern Poland etc – originally North Atlantic)
So it was cloudy cool and wet in those places and the two schemes reinforced each other – THAT is what ‘got stuck’
Yes there were jets in there and up there – from the ground we saw them as = thunderstorms
The problem for the BBC isn’t that it’s cold and miserable here this summer. It’s that it was memorably hot last year.
Weather means that the temperature can vary by 20°C in any place on any particular day of the year, year-to-year.
This is very clear right now as July has varied by the full range from 2022 to 2023.
So if society, the economy, people and wildlife can cope with a 20°C change in a single year, why worry about 2°C in a hundred years?
The weather impact is 10 times larger and 100 x faster!
It’s not that weather means AGW isn’t happening but it proves that AGW is of no importance compared to what happens anyway.
This is very embarrassing to the BBC.
It pretends to be a news service but has been reporting on things that are not newsworthy as though they are the biggest story around.
Such jet stream behaviour is more generally associated with a cooling globe because it involves more clouds due to longer lines of air mass mixing which reduces solar energy into the oceans.
Takes a long time for a trend to reverse though because of oceanic thermal inertia and the fact that ocean cycles in each ocean sometimes supplement and sometimes offset each other.
The development of this years summer high pressure cells in the northern hemisphere with associated high temperature (exaggerated by UHI though) means that the warm air stagnated and failed to get carried to the poles so it was radiated to space in situ.
The polar regions now contain more cold air than usual in store for the next winter.
During the full sequence of the ~65-year natural climate cycle the jet stream operates in two distinct phases.
The climate moved into the meridional weather phase in 2005 and is not going to exit until circa 2035.
This is all natural. Get used to it and plan accordingly.

I do sometimes wonder if the butterfly effect (strange attractors etc) is blocking some changes to air flow patterns. Whether true or not, the implicit irony of climate change being caused by all the wind turbines appeals gretaly (sic) to me at least!
That’s climate “science”, it’s cool because of warming, we read that since years, and nobody really wonders about that BS.
The jet stream getting “stuck” is not a recent phenomena. I give you the 1930’s and 40’s as proof.
Why does history for so many CAGW advocates begin when they were born – i.e. the 80’s onward?
Funny how the headline is about a cold summer when we haven’t had a particularly cold summer, and the article only mentions rain.
From the article: “There is a school of thought that a warming climate is causing this [jet stream] change.”
The jet stream configuration constantly changes. Good luck trying to connect CO2 to these changes. it’s a lot more complicated than CO2.
There is no evidence CO2 has anything to do with the jet stream and its configuration. It’s pure speculation based on nothing.
Prof Liz Bentley of the Royal Meteorological Society seems to have a more measured view of climate change than most warmunists.
Last year she was on BBC Radio 4 ‘World at One’ (17th Feb 22) commenting on a storm in the UK which had the BBC salivating and said
“If you look back over the last say 50 years or so there isn’t a compelling trend that we’ve seen in the amount of storminess we get in the UK”
“we are not seeing any significant changes or trends within the number of storms or maximum wind gusts over the last five decades”
As a child I recall being told that Britain had a maritime – therefore changeable – and temperate climate – normally no extremes but occasionally there were. This explains why the Country is never prepared for very high, or very cold, or very dry, or very wet weather as some other Countries who have routinely extremes over long periods are.
The cost of being prepared for rare and short-lived extremes in Britain would outweigh the benefit.
I am 71 years old and can attest that the British climate has not changed overall since my childhood. The weather however changes frequently, and two years have never been the same in my life to date. I dare say that moving out of an ice age 12 000 years ago towards the tail-end means there is a very slow, slight increase in warming, but I expect we shall know more in about 5 000 to 10 000 years time.
Earth currently has two ice caps – a rare event in Earth’s history where the norm is none and even one is unusual, so we are in one of the Earth’s cooler periods.
Global warming is a relative, not absolute term. So we are warming compared to what, when?
AGW is all things to all people at all times, but all bad.
When EVERYTHING, even things diametrically opposed to one another (e.g., cold and wet vs. hot and dry) are supposedly caused by the same thing, that tells you that YOU ARE BEING CONNED.
The Met Office UK climate projections are for warmer and drier summers, as with the IPCC circulation models, they predict increasingly positive North Atlantic Oscillation conditions with rising CO2 forcing. Positive NAO generally means a more northerly and less meridional (wavy) jet stream pattern. Given that the cooler wetter conditions this July were strictly due to negative NAO conditions, we can safely discount rising CO2 being the cause. I had predicted the hot June and cooler wetter July several months previously, but I doubt that the Met Office would be interested in how the Sun drives the NAO anomalies, or how rough next summer will be.
