Essay by Eric Worrall
Temperatures in the low 90s will cause “An increased chance that some heat-sensitive systems and equipment may fail, leading to power cuts and the loss of other services to some homes and businesses”
Amber warning
Extreme heat01:00 Mon 22 UTC+1 23:59 Tue 23
A developing hot spell is expected to peak on Monday and Tuesday and lead to widespread impacts on people and infrastructure.
What should I expect?
- More people are likely to visit coastal areas, lakes and rivers leading to an increased risk of water safety incidents
- Adverse health effects are likely to be experienced by those vulnerable to extreme heat
- The wider population are likely to experience some adverse health effects including sunburn or heat exhaustion (dehydration, nausea, fatigue) and other heat related illnesses
- Some delays to road, rail and air travel are possible, with potential for welfare issues for those who experience prolonged delays
- Some changes in working practices and daily routines likely to be required
- An increased chance that some heat-sensitive systems and equipment may fail, leading to power cuts and the loss of other services to some homes and businesses
…
Further detail
Following very warm weather on Sunday, very high temperatures are expected on Monday and Tuesday and will likely bring widespread impacts to people and infrastructure. In addition to high daytime maxima, temperatures overnight will remain very warm, especially in larger urban areas, and it will also feel humid.
Temperatures are likely to reach the mid-30s Celsius in places on Monday and Tuesday. Some places, particularly in urban areas, may see temperatures remain above 20 Celsius overnight.
The very high temperatures may continue across a smaller area into the middle of the week, but there remains some uncertainty regarding the extent of this.…

In subtropical Australia we call this kind of weather “Summer”.
My question – what kind of electrical distribution equipment fails in beach weather? When I lived in Britain, we got a few days like that every other summer, and I don’t remember widespread outages.
Is the MET trying to say Britain’s renewable heavy grid cannot handle a surge in air conditioning demand? That the grid might falter if the power which normally flows through the interconnectors to France and Norway gets diverted to keeping Europeans comfortable? Or are they trying to say the grid has not been well maintained? Inquiring minds would like to know.
The terrorism of the UK government weaponised to cause misery and hardship…and at the VERY LEAST…inconvenience…but it’s what Socialists do best…what passes for honour in their diseased minds…
RANT OVER..!
That’s a very BOLD statement.
There’s clearly only one reason that a 90°F heatwave could cause power outages…
This would be criminal negligence on the part of the Grid Operators and those government officials responsible for maintaining adequate grid generation sources for allowing actual maximum capacity to fall below potential demand AND for allowing inconstant generation sources to proliferate.
The millions of Brits living in the US don’t seem to run to bunkers or engage in climate scare syndrome. They either adapted easily or escaped net zero oppression without putting up with it.
What a crock of “maybe”. These temperatures are neither new nor catastrophic. The only real threat is reliance on renewables to help.
Don’t feel bad UK. Here, when it gets hot, they cut the power off intentionally to 100s of thousands because they are afraid of fires.
It doesn’t matter if the electrons are green or not, you get nothing.
You in Cali? Sympathies.
Even Rooftop Solar gives you nothing when grid sourced power leaves your meter in the dark. Rooftop Solar is designed to terminate generation if power fails at the meter to prevent backfeed and potential electrocution of utility workers during outages.
Your power goes out…your rooftop solar ceases to work.
I thought rooftop solar quits when the grid goes down because it requires a power source to operate. Am I wrong? If you have battery storage along with the solar it continues until the storage or sun runs out. Out of all the solar rooftop in my neighborhood only one has battery storage.
The typical residential PV system has an array and a DC-AC inverter, to keep costs down. An off-grid system needs added complexity — a battery (DC) and a charge controller (also DC). To have both worlds, even more complexity is required — a smart switch that isolates the household AC circuitry from the grid when the utility grid goes off and operates the inverter from the battery.
From the article: “My question – what kind of electrical distribution equipment fails in beach weather? When I lived in Britain, we got a few days like that every other summer, and I don’t remember widespread outages.”
There were no problems with electrical grids in the past, before windmills and solar were added to the mix. No blackout warnings.
After windmills and solar were added to our grids, we all get blackout warnings every summer and winter.
Windmills and Industrial Solar are the problem. We should get rid of this problem as soon as possible.
I remember power cuts in the 1970’s due to industrial action, but not in the summer of 1976.
Power cuts in the early 80’s due to industrial action.
Power cut in the early 90’s due to ice storm that coated overhead cables bringing them down.
No power cuts in recent summers despite any increase in air conditioning (still a relatively rarity in domestic settings).
“My question – what kind of electrical distribution equipment fails in beach weather? ”
Simple:
Countries that do not regularly get “beach weather” (well OZ style beach weather anyway).
Britain historically does not.
How do your homes cope with the heat? Are they designed to keep heat in, as are ours (brick that acts as a storage heater for overnight). I suspect not, and I suspect you have A/C. We don’t.
“When I lived in Britain, we got a few days like that every other summer, ”
And when was that? – chances are that there are many more “heat-sensitive systems and equipment” than when you did. Computer/data centre systems FI.
And BTW, the meteorology is indicating a possible 97F max somewhere, and the MetO are likely playing it safe at the mo.
Houses that are designed to keep the heat in, are the same as ones to keep the heat out: open all of the doors and windows at night and keep them closed during the day. Insulation and whatnot, work both ways as thermal barriers. And, there’s a reason they build stone homes in the desert.
Read what I said….
Brick:
Absorbs daytime solar heat which slowly cools overnight, keeping the house hot despite open windows.
Yep. And they are generally the product of choice in Australia. Much more popular after the asbestos built houses. 😉
If the doors are open and the brick is external then the heat should vent outside.
Does this you now agree that significant UHI warming effects exists.
LOL
Of course – locally – I’ve never said otherwise.
Just that as a planet-wide significance in AGW it is not.
LOL, but most of the temperature recording stations are near or inside the UHI umbrella.
I lived in a brick ranch house in eastern Georgia (U.S.) for about 5 years. I would close the windows and curtains during the day and would use a window fan to draw in the cooler night air and run a ceiling fan in my bedroom. In spite of daily temperatures in the 90’s, I would not need to use the A/C except for the hottest days, approx, 5-10 days per year.
I live in the English Midlands. Our house, built in 1932 with solid walls, feels cool in summer and is a pain to get warm in the winter.
Is it shaded from much sunshine?
Does it have a cavity?
June 5, 1950 – The Flying Scotsman train derails at Tollerton, Nottinghamshire due to heat-buckled track.
2 June 1975, A cricket match in Buxton, Derbyshire. between Derbyshire and Lancashire, had to be postponed due to a freak snow storm.
It’s called “natural variability”
I think it’s the only example of the words “snow stopped play” appearing on the scorecard in a newspaper report. I remember it well.
As do I, I was in Buxton and planning to go to the game! A week later hot weather and a drought started which would last over a year (summer of 76).
Do let us know when this 97F occurs, won’t you.
Meanwhile, in Germany, where I am currently, they had 91F the other day. Haven’t heard of any overwhelming problems resulting from that.
BTW, I remember being on holiday in Tenby in 1983. I’m pretty sure it was in the 30s during the day and high teens during the night.
Does the UK have special electrical equipment designed to handle a narrower temperature range than the rest of the world?
One would assume (yeah, assume makes an ass of u and me) that equipment in the UK was much the same as Europe, where even Greece and Italy get snow in the winter.
The incoming UK June heatwave is likely to be record breaking ( just as May’s was) and it will last at least a week in the affected areas.
Just as the UK isn’t designed for or used to extensive snow, it isn’t used to or designed for such heat.
It’s all relative to what you are used to. Excess cold deaths in India are at far higher temperatures than similar deaths in the UK and electrical infrastructure etc. is designed to operate at hotter temperatures.
It’s likely to peak 36C+ but it’s been steadily upgraded and could approach 40C. This would easily beat the 1957/76 all time June record.
“It’s likely to peak 36C+ but it’s been steadily upgraded and could approach 40C. This would easily beat the 1957/76 all time June record.”
Yes, I wouldn’t rule out 38C but 40C is a stretch.
“I wouldn’t rule out 38C”
Especially when measured at Met-Office sites !!
No.
Via meteorology:
It depends whether the heat dome currently over mainland Europe spreads to cover the U.K.
30°C a very high temperature ? An extreme heat ?
What are those 30°C sensitive systems ? Snowflakes ?
Do they hire clowns at the Met Office ?
It has nothing to do with systems.
This strategy is called predictive programming.
Power Outtages will become the norm in the green energy Utopia – therefore the blame must be preemptively shifted, before people start blaming it correctly on renewables.
And maybe they’ll false flag an outage to teach people a lesson.
Never waste a crisis – especially not the one you created.
From a more objective point of view: Brirains heatwaves are chicken shit compared to most parts of the worlds.
UK heatwaves are considered cool breeze in many hot 3rd world countries – and even those
don’t have Power Outtages – at least not heat related ones.
How can a more advanced UK grid struggle then?
Only by design.
Only by LACK of design. Blame the folks that failed to engineer a sufficient reserve into the system.
They do not hire them, they are the clowns themselves.
Yes, it is for the UK -do you live here?
I don’t know how old you are, but we have had temperatures of 30 degrees Celsius in my 70 year lifetime, most notably in 1976. The other thing to remember is the location of the thermometers.
I am 71, 72 next month and worked 32 years for the UKMO. 20 as an on-the-bench forecaster.
In 1976 I worked at RAF Binbrook and RAF Leconfield as a weather observer
For 5 and 11 sqd Lightning jets.
I very much remember the summer of 1976 as I had to commute from north Lincs via ferry across the Humber and up to Leconfield and stop in the sergeants mess for my round of shifts. The Humber bridge was still under construction.
Point is, it was not a regular summer occurrence …..
https://www.metoffice.gov.uk/blog/2025/scorching-junes-how-often-do-we-see-temperatures-over-30c-in-june
”Using Met Office station data from 1960 up to the current day, a clear upward trend is visible in the number of weather stations recording temperatures of 30°C or higher during the month of June, a threshold once considered rare in the British Isles.
In the 1960s and 1970s, such high temperatures were infrequent and typically short-lived. For example, in 1961 and 1968, only a single day in June saw any station reach the 30°C mark. However, the summer of 1976 marked a dramatic shift. That June, the UK experienced an extraordinary heatwave, with multiple stations recording 30°C+ temperatures over nine consecutive days. This event remains one of the most intense early-summer heatwaves in UK history and the 1976 Summer as a whole is still the UK’s warmest summer on record for average maximum temperatures based on a series from 1884.
Following a quieter period in the 1980s and early 1990s, the frequency of these hot days began to rise again in the 2000s. The June 2005 heatwave saw over 80 stations report temperatures above 30°C on a single day. More recently, June 2017 and June 2020 featured multiple days of widespread extreme heat, with dozens of stations across England and parts of Wales and Scotland hitting the 30°C threshold.”
Sounds cyclical. Akin to the 30year Positive/Negative phasing…
.
Atmospheric and oceanic research indicates that distinct 10- to 30-year ocean variability regimes exist in the Atlantic alongside the traditional 50- to 80-year Atlantic Multidecadal Oscillation (AMO).
These shorter, decadal-scale rhythms operate differently than the classic AMO:
So you were a loyal, committed employee.
Why did they sack you?
If he was ever involved in looking after Met-Office temperature sites…
… it would have to be for incompetence.
Ah, the ever to be expected ad hom when stumped for an intelligent reply.
Many of your replies are absurd which is why you are getting some flack in return.
Many here are fed up with the warming hysteria bullshit!
What makes 30ºC a ‘threshold’?
What about the spring/summer of 1947, which I understand was hot as well, with the May temperatures only being beaten by the temperatures of last month?
Look, I’ll repeat the word …. “regularly”.
So you must be aware that the Kew Gardens weather station is situated in the middle of 4 hot houses, on a concrete slab. It records temperatures 5C higher than the surrounding area because of its compromised location. Yet the Met office use it for the London temperature, on the BBC weather maps. It’s clearly fraud.
Kew Gardens weather station is not on a concrete slab, it is situated in the centre of a grassy park over 30m away from the nearest tree and over 80m from the nearest building. As a result it will actually measure a lower temperature than the surrounding urban district.
I spent a month in London one week in June 1990 🙂
The temp topped 30C a couple of days.
Poms in the noon-day sun sitting on the edges of fountain ponds with their feet in the water.
The first rule of 30C is –
stay out of the sun.
Mad dogs and Englishmen?
At 30?
I thought it was “keep hydrated”, or perhaps “slip, slop, slap?
Just wear a long sleeved shirt and a hat working outside, and keep hydrated.
Yes, it is for the UK (or at least used to be).
– do you live here?
“Do they hire clowns at the Met Office ?”
No, but they frequently get them on here criticising them from ignorance.
Yes, it is for the UK.
– do you live here?

No, but they frequently get them on here criticising them from ignorance.
An American in England’s take ….
https://youtube.com/shorts/oryPxrcx2yc?is=qXq2W5Nov2jK1Eg2
So, are you saying it is not ignorance..
… but that the corruption of the Met-Office temperatures is deliberate !!
Ok.. you are probably right.
QED:
“No, but they frequently get them on here criticising them from ignorance.”
We regularly see 86°F (30°C) in California.
That is the average high in late May in my area nobody complains.
Mid 80’s really, they struggle in it?
BWAHAHAHAHAHAHAHA!!!
This is 12 degrees below the average human body temperature which can easily cool itself via sweat glands and simple consumption of water.
That’s really pathetic of a government to be associated with such nonsense.
Power outages due to heat? Lightning and wind storms maybe but heat? No
The power cuts angle does seem unlikely, there were a few minor local problems in 1976, but nothing widespread. But then there was negligible solar PV and wind power back then and a far more stable and controllable grid.
Well,actually, now that you mention it-yes…but so very rarely as not to matter. I’ve seen the “high lines” sag and droop so low as to seem worrisome in serious Midwest heat, and I do mean serious, but it’s so rare, and to my knowledge not fail. Its the local lines that go-transformers, sub stations-the like.
If it does result in power outages, it will because they spent their money building wind and solar rather than power systems that work.
That is actually funny someone at the UK Met office doesn’t know there is an electrical standard BS 7671 for the UK
Section 522.1.1 the ambient temperature range for general electrical equipment is -5°C to +40°C, with a daily average of no more than +35°C. Equipment designed to operate within this range does not require special ambient temperature marking.
Regulation 714.512.2.1 details outdoor lighting and equipment ambient temperature range of -40°C to +40°C.
If you have equipment failing at 30 deg it by definition doesn’t meet the UK standard.
It clearly states
Anyone involved with electrical systems must adhere to BS 7671, including:
You are forgetting that if the standardised measured air temp. is 40C, lots of equipment in the sun outside and in shut up houses will be considerably hotter.
He is also forgetting that the MetO talks to its customers, among which the Grid and Gas companies are amongst the biggest and as a result are well aware of their concerns.
Talks to customers, but can’t manage to maintain a reasonable temperature measuring system.
What use is that !
A measuring system is used after the fact of a forecast … so now tell us the the UKMO suck at that.
It’s all you’ve got – ad hom, conspiracy and accusations of incompetence.
Oh forgot – your 1st LoT busting nonsense of EN’s magially creating the warming.
Keep it up – you are a credit to deniers.
Stop with your bull the MET has been exposed many times here, it is overwhelmingly evident that YOU are going to lie all through it.
The Met office knows of the problem is bullshit do you even understand what a licensed electrician has to do with such equipment … he has no choice or he loses his license… here is what he has to do
The answer to MrGrimNasty if you didn’t search it for the selling company
1.) Sales Ban & Seizure
2.) Mandatory Recalls
3.) Criminal Prosecution
This is not something the Met office or anyone else even gets a say in and you are all dribbling bullshit. Electrical equipment in UK has to meet the standard there are no exceptions apart from military who can do whatever they like.
The “talk” is at the level of what power is required when nationwide temperatures reach certain levels.
So stop your “dribbling bullshit”, and try calming down – hatred only hurts you. We are all going to die after all.
You might be talking about power requirements and loads. This particular part of the discussion was about how well electrical transmission equipment handles moderately warm weather.
Well you stop pushing rubbish and lies …. electrical safety has an authority with the sole purpose to ensure the safety of the public. If equipment was going to fail at xyz temperature they would simply up the temperature in the standard. They don’t have to ask politicians, the Met, idiot activists or anyone else that is there sole function and powers they have.
You are ignoring that outdoor equipment has even higher ratings .. what is clear is none of you have anything to do with electrical standards.
Do you even know what happens if you have a manufacturer that fails the standards … search it not hard help let me help you
“What happens if equipment sold in UK fails electrical standard BS 7671”
You are all layman thinking making crap up.
The temperature range is for the equipment.
Unless somebody has done something very wrong, the enclosure and heat sinks should ensure the equipment doesn’t get much above air temperature. Don’t forget, transformers produce quite a bit of heat when they are operating.
When does the inside of a house in the UK get above 40C?
The forecast for my town for Thursday is only 0.4C below the all time record, regardless of month.
This clearly is a very significant UK heatwave if the forecast is correct.
Yawnnnnn, it was 91 F (33c) in my city and it was easy to handle as it was 7F below the average human body temperature.
I’m in Spain, what the UK is describing is weather that we have from the beginning of June until the end of August, almost without a single day’s break.
The climate alarmism is reaching levels in the UK, which is so ridiculous that only a climate nutcase could believe it.
Please, Nigel Farage, get in and sort this out.
So let me parse that …
Because the UK now gets weather that is routine for Spain (~ 500 miles south), and has been for centuries, but has appeared here over the last 2 decades or so (NB I said regularly), then “alarmism” is somehow the province of a “nutcase”.
The real issue is not this.
As far as UK summers go, Paul Homewood regularly posts charts of historical UK temps and they don’t show anything remarkable or alarming happening. No hockey stick in recent times.
UK seasonal temperatures are very variable as you would expect from an island with the Arctic to the north, an ocean to the west, the Sahara to the south and a continental landmass to the east. Weather systems move across, sometimes they stay in place for days or weeks because of blocking highs. Sometimes hot air is drawn up from the south and cold air from the north.
But that’s not the real issue. The real issue is, suppose there is unprecedented UK summer warming. Does that make the current energy proposals any more sensible? Does that make it any more plausible that they can run the UK grid off wind and solar without any adequate plans for dealing with intermittency? Does it make the huge investments currently required for this plan any more affordable? Of course not. And even if the plans worked, they would have no effect on global temps, and still less any effect on the supposedly extreme weather.
The UK going to Net Zero because UK hot summers is like Tuvalu reducing its emissions because rising sea levels. Or, a UK example, its like some UK town declaring itself a Net Zero town ‘because hot British summers’. Or the crazed Energy Secretary trying to ban non-condensing tumble dryers, heated towel rails and underfloor heating, and selling this stupidity as climate action.
The real issue is that the current UK energy plans are totally irrational, and not justified by any claims about UK or world weather trends. The idea that Net Zero is a rational response to hotter UK summers is insane. All its doing is bankrupt the country and wreck the grid without having the slightest impact on the summers.
In what alternate universe is it more important to spend billions on sequestering trivial amounts of CO2, when the country has practically no navy and tiny under equipped defence forces, a collapsing health service and an ongoing disaster in education? That’s what it amounts to. In any other context it would be called what it is: obsessive-compulsive disorder.
“Paul Homewood regularly posts charts of historical UK temps and they don’t show anything remarkable or alarming happening. No hockey stick in recent times.”
I didn’t say there was – there is though a greater and more extreme heatwave incidence – even the summer of 1976 only produced a maximum of 35.6C, which remains ( for another 2 or 3 days) the UK’s hottest June day.
The Net Zero program is idiotic as a response to UK weather trends. The ones in this chart, or any others. Because, as I say, all it does is raise the cost of generation and delivery, make the grid unstable, and it has no effect on either the local or the global weather.
People need to stop claiming that Net Zero is in some way connected to the climate, and that if you can show a hockey stick that in some way is an argument for it. It cannot be justified by any claims about weather or climate. It is not working and will not work to supply reliable and affordable electricity. And it has no effect on weather or climate.
As the UK is now finding out.
Bingo, well-stated. All of this will have zero effect on air temperatures.
It was much hotter in Roman times. The Sun has cycles, your inane drivel won’t affect them.
And here I was, happy our highs have dropped to 105F for a few days
Where is “here”?
sounds a bit like Tucson, AZ – – not a fun place to be in June
The weather forecast for where I live is 32 degrees Celsius Tuesday to Thursday next week. The definition of a heatwave is three days or more of temperatures in excess of 25 degrees Celsius in most of the U.K. , for London the minimum temperature for a heatwave is 28 degrees Celsius.
1976:
”Heathrow had 16 consecutive days over 30 °C (86 °F) from 23 June to 8 July and for 15 consecutive days from 23 June to 7 July temperatures reached 32.2 °C (90 °F) somewhere in England. Furthermore, five days saw temperatures exceed 35 °C (95 °F). On 28 June, temperatures reached 35.6 °C (96.1 °F) in Southampton, the highest June temperature recorded in the UK. The hottest day of all was 3 July, with temperatures reaching 35.9 °C (96.6 °F) in Cheltenham.
The great drought was due to a very long dry period. The summer and autumn of 1975 were very dry, and the winter of 1975–76 was exceptionally dry, as was the spring of 1976; indeed, some months during this period had no rain at all in some areas.[citation needed]
The drought was at its most severe in August 1976 and in response Parliament passed the Drought Act 1976 to ration water.[7] Parts of the south west went 45 days without any rain in July and August. As the hot and dry weather continued, devastating heath and forest fires broke out in parts of Southern England. 50,000 trees were destroyed at Hurn Forest in Dorset. Crops were badly hit, with £500 million worth of crops failing. Food prices subsequently increased by 12%.[8]
In the last week of August 1976, days after Denis Howell was appointed Minister for Drought, severe thunderstorms brought rain to some places for the first time in weeks. September and October 1976 were both very wet months, bringing the drought to an end.
The Haweswater Reservoir had only 10% of its water left; people walked dryshod on its bed 60 feet (18 m) below its normal water level. The site of the flooded village of Mardale Green was dry.[9] Ladybower Reservoir in Derbyshire dried out and revealed the flooded villages of Ashopton and Derwent.[10]
In Ireland the temperature reached 32.5 °C (90.5 °F) in County Offaly on 29 June 1976.[11] There were also gorse fires in County Wicklow.”
As the UK had such heatwaves during the ice age scare
they should be a nothingburger in a warming scenario 🙂
In June 1970 for 21 consecutive days, it was above 100F (38C>)
In July 1971 for 17 consecutive days it was over 100F reaching a then record high of 113F (45C)
The trees, shrubs, grass all survived well including the shelterbelt that ran behind my back yard to block the strong prevailing winds.
There was no sudden population decline and my own house use a large swamp cooler and did fine with it.
MO Amber alert: the rest is bolleaux
90F or 32C … just a nice warm day … causing problems? Get real!
MO is now currently forecast 39C for London mid week. Insane.
Heathrow and Kew gardens ??
Yes, likely that nice park with acres of grass and trees – yet somehow it often turns out to have been hotter than Heathrow with its acres of concrete and jets (sarc).
No Kew garden runs hotter than surrounds and why it gets a class 4 site. I covered the same garbage from phil when he tried to claim it is cooler.
“Kew garden runs hotter than surrounds”
Wot, as in the conurbations surrounding?
Also, some proof please …. as in measured data.
surrounded by hot houses on a concrete slab. It’s fraud.

Seeing is believing … except of course to hard-core denizens of WUWT …..
https://maps.app.goo.gl/8zAte6qm3jJ9UA1m7
So stop dribbling and look up the official reason for the site being class 4 it tells you the reason. I posted the official statement here
https://wattsupwiththat.com/2026/06/20/kew-gardens-is-just-another-worthless-junk-site/#comment-4208631
There are 3 clear reasons why it reads high none of which are easy to filter or adjust for.
This is the problem with you activist types you seen something and jump to a conclusion which is often wrong.
“This is the problem with you activist types you seen something and jump to a conclusion which is often wrong.”
Exactly!
The problem indeed:
(Activist as in peeps ideologically motivated to object to AGW science) is ignorantly demonstrated at this place
This is the usual reflexive opinion of the motives of peeps who post on here that do not sing with the choir.
I have professional knowledge of meteorology and am deffo not an activist – voted for Brexit actually.
That you view any connection to the MetO as being automatically “activist” is your conflating specialist science that has political implications you object to, as being a part of it. No, I cannot refute that enough. Of course people have a political leaning – that is the case in all walks of life.
“Proximity to Microclimatic Obstructions: The automatic weather station and its traditional Stevenson screen are located on a lawn within a highly managed botanical garden. Over the years, the construction of nearby features—such as temporary festival structures, visitor paths, and large arboreal canopies—has compromised its open-air profile.”
No it is obviously in “open air” and arguably actually does not represent it’s (wider) surroundings in the sense that outside of the gardens temperatures on hot summer days will actual be hotter not cooler.
“The Urban Heat Island (UHI) Buffer: Kew Gardens is embedded deep within the greater London metropolitan sprawl. While the immediate ground is grass, it is surrounded by thousands of square kilometres of tarmac, concrete, and domestic heating systems that artificially trap nocturnal warmth.”
I don’t dispute that – but once the surface inversion has been broken (temps will rise quicker than otherwise until that happens) then any extra nocturnal heat has convected aloft with the thermals then being generated from the surrounding grassy surfaces (under summer conditions).
Measuring from google maps I find that the enclosure is 25m from the closest path and 85m from the closest building, with indeed a bunch of trees between.
Warmed air represented by convection bubbles do not travel horizontally – they rise vertically – and if a breeze is sufficiently strong then turbulent mixing occurs – again drawing in surrounding cool air.
Ergo warmed air from a path 25m away will not affect temps at the stevenson screen, and deffo not from buildings 85m away.
BTW:
Where does the WMO say that temperature measured in cities (even in open parks) is verboten?
Why tell me I didn’t write the report and make the site 4 classification some experts did go argue with them. You also seem to be only addressing one of 3 problems.
To me you have already shown you make stupidly false claims about electrical safety a subject you seem to know nothing about. Do you really expect me to believe you over some experts on site classification. Sorry I don’t care what you think you have zero credibility.
Yes, you did respond with garbage to my statement that the temperature in the middle of a grassy park would not be as hot as the surrounding urban district!
I guess such heat events have never occurred before, and if they have, how did the general population handle them? Was there a spike in heat-related deaths, illnesses, power failures, water shortages, etc.: or did everyone make the usual adjustments for above- or below-normal weather conditions and get on with living their lives? The climate alarmists consistently hope for the former occurrences so that they can demand major operational and living changes. The overwhelming majority of the population just ignores them.
There is an easy solution to this, fire up all fossil fuel and nuclear power plants. Build new fossil fuel and nuclear power plants. Remove all wind and solar from the grid. With the money you save from fossil fuel and nuclear and strengthening of the grid from fossil fuel and nuclear we will have money to buy air conditioning and plenty of power to operate them.
A mid-latitude continental climate [Köppen BSk] would, apparently bring the UK to its demise.
