ONS Peddling Fake Heatwave Deaths Scare

From NOT A LOT OF PEOPLE KNOW THAT

By Paul Homewood

It was only two weeks ago that I wrote about the official cover up of excess deaths in winter. It did not take long for my suspicions to be confirmed.

Last week the Telegraph reported:

Three times more people die during cold snaps than when the weather is very hot, official data show.

Figures from the Office for National Statistics (ONS) show that from 1988 to 2025, about 42,000 people died on the hottest days. On the coldest days almost 150,000 died, in the same period.

However, data suggest the difference between the numbers of deaths because of cold and heat is shrinking.

The average annual death toll from cold in the 1990s was four times that of heat. But in the years 2015-2025, the difference shrank to 1.5-fold.

This trend is being driven by more frequent and persistent periods of very hot weather, which have resulted in heat-related deaths peaking in the summer of 2022, when temperatures in the UK reached 40C for the first time on record.

There were an estimated 4,652 heat-related deaths in England and Wales in 2022, the highest figure for any year on record.

Three of the five highest years were in the past 10: 2025 (2,805 deaths) and 2018 (2,617), along with 2022.

All figures are based on modelled estimates of mortality and are not actual counts of deaths directly caused by extreme weather.

Commenting on the findings, James Tucker of the ONS said: “As our climate changes, including more frequent and prolonged periods of very hot weather, it is important to understand how both heat and cold affect mortality over time.

“Our results show that the gap between heat and cold-related deaths has narrowed in recent years as the proportion of heat-related deaths has increased.

Full story here.

The number of heat-related deaths itself is absurdly meaningless – 42,000 sounds a lot, but over 38 years it is barely a thousand a year. Compared to annual deaths of over 600,000, that is microscopically tiny. These deaths are supposedly excess deaths over and above what might have been expected.

But the numbers are not even calculated from actual data, which should be a simple enough task; instead, they are “modelled estimates”, as the ONS describe:.

We used a statistical model to estimate the relationship between temperature and mortality, while accounting for other factors that may influence mortality risk, for example, air pollution.”

Clearly the Government’s Net Zero agenda is badly compromised by the fact that excess deaths in winter number in the tens of thousands every year; by contrast, deaths in summer are always the lowest of any season. Last year was no exception:

To most, a warmer climate in Britain is a good thing.

So, step forward the supposedly independent Office for National Statistics (ONS). According to their computer models, more and more people are dropping like flies every time the sun comes out; and the problem is getting worse. If this were true, of course, what is killing off people in spring, when the death toll is 6% higher than summer? April showers?

The ONS report gives the game away that this is a politically motivated one when it says:

“The impacts of temperatures on human health are of global concern.”

However, this new ONS study falls flat on its face with the claim that:

“2022 saw the highest daily temperatures recorded for England and Wales. This caused an increased number of heat-related deaths in 2022, compared with surrounding years (estimated 4,430 deaths in England and 222 in Wales).”

But back in 2022, three months after the heatwaves, the ONS carried out a very detailed study into mortality during the time. The data clearly showed that, although deaths spiked on the hottest days, they quickly dropped below average levels over the following days.

There had in effect been a short-term mortality displacement. People who were already dying simply passed away a few days earlier than they would otherwise have done. The heatwave did not kill them; they died naturally because of underlying disease.

Although the new ONS study only covers up to 2025, they do mention analysis by the UKHSA, the UK Health Security Agency, which claims that an estimated 753 heat-associated deaths occurred during this year’s May heatwave in the last week of the month.

However, the UKHSA use the same faulty methods as the ONS.

The number of deaths during the week of the heatwave, Week 22, was above last year’s figure, but was also well below normal in the following three weeks. Across the four-week period, there were 1731 fewer deaths than the same period a year ago.

Such a shoddy misuse of statistics puts the ONS in a bad light. It’s even worse when it is clearly being done at Government diktat.

The Office For National Statistics…

None too forthcoming as far as SARS-CoV-2 was concerned…

A one-trick pony…

Central heating and air conditioning.

Oh yea. Cheap energy to operate them.

ONS and statistics – reminds me a famous aphorism…

“statistics is like a bikini – used to cover up the most interesting bits”

So it’s all down to hotter summers and not milder winters?

Agreed. The gap between cold and hot has lessened. All is attributed to increase in hot without mentioning reduction in cold.

In February 2024 the ONS changed its method of calculating excess deaths from a method which was very simple to follow to one which was obscure and not well explained. ons methodology changes
My response to this included errors in the ons spreadsheet dataset20240220.xlsx , these errors have not been corrected.

I wanted a new Jaguar to impress my friends at work … but I couldn’t afford one.

For some reason, my friends aren’t impressed by the model Jaguar I bought and keep on my desk.

I suggest that those interested in the heat deaths vs. cold deaths spend a few years working in an emergency room that serves the indigent living on the streets.

Aha! Copilot AI …

Heat vs. Cold (2000–2020)Source: JAMA Network Open (2025), using CDC National Center for Health Statistics death records.
Average annual deaths attributable to temperature:

  • Cold-related deaths: ≈45,992 per year
  • Heat-related deaths: ≈3,414 per year

Cold accounts for ~13× more deaths than heat in long‑run averages, largely because cold exposure is chronic and diffuse across winter months.

Emergency Room (ED) Impacts
Heat waves sharply increase ED visits for:

  • Heat stroke / heat exhaustion
  • Dehydration
  • Acute kidney injury
  • Cardiovascular stress
  • Respiratory distress

Cold exposure increases ED visits for:

  • Hypothermia
  • Frostbite
  • Falls/trauma related to ice
  • Exacerbations of cardiovascular disease
  • Carbon monoxide poisoning (heating mishaps)

While the JAMA article does not provide national ED visit counts, CDC’s Heat & Health Tracker and multiple regional studies show thousands of excess ED visits during major heat events. (This is an inference based on the known relationship between temperature extremes and acute morbidity; the specific ED counts were not provided in the cited sources.)

“ONS Peddling Fake Heatwave Deaths Scare”

Really? They haven’t rebuilt their reputation yet:

“Deep seated” issues must be addressed before the UK’s official statistics agency can “rebuild its reputation”, according to a highly critical government review.

Repeated problems with Office for National Statistics (ONS) data, which are used to make decisions affecting millions of people, led the government to set up a review of the organisation and its leadership. – 26 June 2025, BBC

The long march through the institutions seems complete.

On the subject of peddling falsehoods, Journal Creep.

Story Tip:

One of the more distressing changes in science is its infection by politics and ideology, a change visible in what I call ‘journal creep’. Until recently, the primary function of scientific journals was to disseminate research. Now, however, many journals have adopted an additional mission: promoting ideological, moral or political positions. This newer mission, which endangers not only the reputation but also the practice of science, is seen clearly in a recent editorial in one of the world’s most prestigious scientific journals, Nature. …
Nature’s editorial is titled ‘The Death of Jason Arday Must Prompt Deep Reflection’. Unfortunately, the reflection Nature demands does not involve asking how someone with such a thin academic record and a history of exaggeration and lying managed to secure such a prestigious position. Rather, Nature is concerned with assigning blame for Arday’s downfall and death, and the blame falls on everyone but Arday himself.

The “The Review | Opinion” is by “Jerry A. Coyne is professor emeritus of ecology and evolution at the University of Chicago. He is the author of Why Evolution is True and Faith Versus Fact: Why Science and Religion Are Incompatible.” This is encouraging from The Chronicle of Higher Education as I saw more bigotry towards dedicated teachers from some ‘researchers’ which was confirmed by a black janitor in Louisiana. Haven’t read this piece or second book but I taught some evolution and was very impressed by his evolution book that my daughter had. I thought it was important to other areas of biology. Penguin Books paperback, if I was still teaching would use it. It is unfortunate that countering the politics is taking up so much valuable time.

This article lacks sufficient data to make heat death attributions possible.

WHAT WERE THE “HOT” TEMPERATURES during the claimed heatwaves?

September 10, 2026 6:54 am

Heatwave Deaths …

No such thing occurs, in the real world-of-moisture that defines our lives.
Lived Experience [mine] persuades me of this awful truth.
Death by dehydration, sure; by Electrolyte-Imbalance, oh heck yes.
But true Hyperthermic-Mortality is as nothing contrasted with Hypothermic-Mortality:
A Person gets cold, shivers involuntarily, but only up to a point — the muscles go into tetanus, then fail. And then they are gone, seemingly beyond res[c]uscitation.* [Hans Castorp, in the snowy mountains of Davos (CH), provides the best first-person account, in the Magic Mountain (Der Zauberberg, by Th. Mann, ca. 1914 A.D.) ] Having saved at least two (2) healthy-&-fit hypothermia victims, in just the past decade alone, I can attest to its quick-killing potency.

But Hyperthermia, not a chance. Here’s my story (1974, 14-yrs-age):
Mid-summer day, near Mesa, Arizona, working at my father’s water-company, outdoors in the Desert Heat, we started at 04:30 A.M., and cleaned up before high noon, at which point the temperatures (in the shade) regularly exceed 40-, nay 45-degrees Celsius. Hard Labor: ‘Trenching’, Pipe-Laying; Pipe-Fitting; 8′-deep.

Finishing up by 12:00, I had to catch an hourly bus home, 13-miles distant. But the bus was frequently late, so I amused myself at a convenience-shop, just across the divided highway (Apache Trail at Crismon Road). And if I missed that bus, I’d have to wait an hour, back at the offices, or until my Dad finished up ~ 4 hrs later.

On that day, the bus left without me. Faced with an unpleasant choice (above), I grabbed another ice-slushie drink, and set out on foot to run-walk home. 13 miles. On my bike, 30-minutes of stiff breeze. In the cool, I could’ve made that within 90 minutes. In the heat & on foot, I added distance by diverting into the citrus orchards, palm groves, a dip in the ditches (canals) etc. No telecom in those days. But also no need for hitch-hiking.

When I arrived home, a good two (2) hours late, my mother took one look at my face, and turned to the bathtub, filling it with cool (not cold) water, maybe ~ 86 F (30 C)? Within 10 minutes of that immersion, and a few salt-tablets consumed, I was hungry, then sleepy, then fully recovered by the time my Dad arrived home for his Dinner.

The best consequence of that adventure was that I was relieved from trenching duties, in favor of a cushy car-wash job just a mile away. The next summer, at age 15, I worked forestry, living above 10,000′ (3,000+ meters) high in the SW-Utah mountains …

[Speaking of which, one Tyler James Robinson of nearby Washington County / Saint George, languishes in a Utah-County prison, where Justice may (never come). He is the confessed assassin, on this very 10th-Day-of-September (2025 A.D.) of that young champion of the Free Expression & Dialogue, sine qua non, one Charles James Kirk, of Scottsdale AZ, may his soul R.I.P.]

… where we boys experienced the near-death cold of a mid-summer snowstorm, and deep chills after sunset. Altitude sickness could kill, as it regularly did my aging relatives after their late-Summer returns to our ancestral grounds. But never heat.

From which one [we] must conclude:
You can never kill a Person with Heat, only via desiccation. [Even in the bone-dry Kalahari Desert of The Gods Must be Crazy, the children knew how to implant the delirious European in the moist earth, to maintain his life & sanity.] In the Arizona Desert, one can die from a bullet ripping out your throat (Robinson vs. Kirk), from drowning in the flash-floods, from mineral deprivation (sea-salt), from altitude-sickness (ascribed to ‘old-age’ / natural causes), or even from Hypothermic Shock, on a cold-wet-&-windy evening … but not ever, no Never, from Heat-Shock.

The Statistics quoted in the Article (above) are False, it’s a perverted mis-attribution science, thru-&-thru.

Thanking your for your intense attention to this most-vexing matter, [we] remain
Faithfully Yours, — RLW, writing on behalf of Prof. A. Friend, he is never-AI-aided.

*But as ancient miracles attest & modern medicine may demonstrate ‘You’re only dead once you’re Warm & dead’; it’s the too-rapid re-thermalization (thaw) the induces cell-death.

Obviously the excess deaths in spring are not due to April showers, they are due to the pollen of the May flowers! As for the autumnal excess, I would look at overconsumption of beer for Oktoberfest; or the strain of bringing in the sheaves!
As an aside, do the autumn models all look like the St. Pauli girl?

No where in the presented analysis are population demographics included.
Age
Sex
Country of origin (migrants)
Health status prior to death

And total population and population distribution.
