Germany’s DWD Weather Service Redefines “Heat Wave”: Now 3 Consecutive Days Of Warm Weather!

From the NoTricksZone

By P Gosselin 

Like the WHO changed the definition of a “pandemic”, the DWD has changed the definition of a “heat wave”…all to falsely generate the sense of a crisis? 

Repeat a lie often enough, and in no time the masses start believing it’s true. Probably few institutions know this better than Germany’s DWD national weather service.

In order to get people to believe more in runaway warming, they have to be led to believe that “heat waves” are occurring ever more often. Even though it’s been not an unusually hot summer here in Germany (yes, it’s been hot at times), all we hear on the media are news about heat wave after heat wave.

To allow this, it seems the DWD changed it’s definition of “heat wave” so that now any brief period of warm temperatures qualifies as one. What used to be defined as a period of 5 consecutive days with highs over 30°C, has been changed to a period of just three(!) consecutive days – with a high of 28°C or more. That’s all it takes, folks! It’s truly baffling that Florida could be so popular among retirees.

Hat-tip: Snowfan

Here’s what the DWD writes at its website (excerpt):

A heat wave is a multi-day period of unusually high thermal stress. A heat wave is an extreme event that can damage human health, ecosystems, and infrastructure. In our latitudes, heat waves often occur in connection with persistent summertime high-pressure conditions (high-pressure area).

Internationally, there is no uniform definition of the term heat wave. Definitions are often based on a combination of percentile-based thresholds (e.g. 98th percentile of daily maximum values and a minimum duration e.g. 3 days).

The following heat wave definition is used in the production of the “Climate Maps of Heat Waves” in the German Weather Service:

Individually for each grid point, a threshold value for each day – corresponding to the 98th percentile – is calculated from the daily temperature maxima of the reference period (1961-1990). To increase the database of 30 values (1961-1990), the 15 days before and after the date are also used, which increases the database to 930 values and also results in smoothing. If the current grid values of the temperature maximum are above this climate threshold and above 28 °C for 3 consecutive days or more, a heat wave is present for the marked area and period.

Heat waves pose a major risk to health, especially for the elderly and sick. For this reason, the German Weather Service uses its heat warning system to warn of days with high thermal stress on the basis of the felt temperature and a simulation model to calculate the heat stress indoors.”

It’s not clear when the DWD changed to this new, low-bar definition. The World Meteorological Organization defines a heat wave as five or more consecutive days of prolonged heat in which the daily maximum temperature is higher than the average maximum temperature by 5°C (9°F) or more.

But for the DWD, a regular warm summer weekend – when it’s just barely warm enough to swim in comfort in the daytime – now qualifies as “unusually high thermal stress”. Result: the media play along and keep reporting on “another heat wave” almost on weekly basis.

Heat wave after heat wave

If we take Berlin and apply the DWD’s new definition for the year 1992, for example, Germany’s capital in fact saw 7 heat waves that summer: May 21-23, June 2-5, June 27 – July 1, July 8-10, July 19-21, July 30 – August 3 and August 5-10. Yet, back then Germans were not bombarded by the media with news of heat waves. Back then it was: it’s summer, stupid!

And note how the DWD uses the ancient 1961-1990 reference period for comparison, a time when the mean temps were about a degree lower and all the talk was about global cooling and the next ice age. This is the trick used to justify 28°C as “unusually high thermal stress”. Never mind that days with highs in the upper 20s often come with nights with temps in mid teens that have people grabbing their jackets.

Not a super hot summer

Anecdotally, this year I can say it’s been a warm and pleasant summer here in northwestern Germany; it was certainly too dry. But I didn’t think it was “a scorcher” because so many evenings were too cool to sit outside without a jacket. Moreover, there was not a single night that I found it to be difficult to sleep. And during earlier hot German summers, I remember having the electric fan running in the office for days. This summer I never had to use it once.

It’s a bit like the WHO changing its definition of a “pandemic” so that authorities are now able to declare a crisis anytime a grippe breaks out.

WHO changed pandemic definition , in a small way, way back before 2010

The Covid outbreak was definitely a pandemic under any definition. Just thought I would correct the authors claim

Duker, I would tend to agree with you except for the fact that the PCR test was so notoriously unreliable and so easily scammed, even the CDC got rid of it in favor of the Antigen test and the fact that hospitals in the US were reimbursed many thousands of more dollars for ventilator patients if they were diagnosed with Covid than if they were not, so I doubt we have any true idea of how widespread and deadly Covid really was. After all, the flu has mysteriously “disappeared” since Covid was unleashed upon us. Also, there are many reported cases of even victims of motorcycle accidents having their cause of death listed as Covid. In the UK, during Covid, the average age of death during this period, per UK Gov. statistics, was 82, well above normal life expectancy.
You may well be right but there are many caveats to your conclusion.

Flu disappeared ?
October 1, 2021–June 11, 2022, CDC estimates that influenza virus infection resulted in 8.0–13.0 million symptomatic illnesses, 3.7–6.1 million medical visits, 82,000–170,000 hospitalizations, and 5,000–14,000 deaths in the United States.”
You are a complete fantacist.
The US excess deaths , not even thinking about the cause. In last few years way exceeds the ‘official ‘ Covid death numbers – which normally require a diagnosis but plenty still died outside medical system.
That’s 1 mill who died who otherwise would not. Ever wondered what the cause was?

Duker, can you provide a link to your flu stats, please? I’d appreciate it. Also, the dates you provide for excess deaths do coincide with dates for excess deaths which may well have been caused by the vaccines for Covid, not Covid.
Also, I said I tend to agree with you, I merely pointed out info that might indicate the Covid death numbers may well be greatly exaggerated and the reasons why. We don’t know. Plus, your data should start from 1/20, at least, not 10/21.

Both of these topics are of interest to many. In any case, you started the thread in your response to the definition of “pandemic” so perhaps a little less condescending tone is in order.

Your statement about vaccines didn’t come till well after half a mill died in the U.S. is not quite correct. A half a million covid deaths were recorded to have occurred in the second week of February of 2021. There was an overlap of at least a couple of months.

KcTaz reasonably responded to your initial comment and brought up some good points.

I think we can all agree that established definitions are seemingly being changed often to meet certain narratives.

German report reveals 1 in 25 insured individuals treated for Covid shot reactions – the vaccine reaction
Take these numbers with the usual “grain of salt”. Nevertheless:
Not long ago this number was 1 in ~1000 – if people keep taking these toxic jabs it will be 1 in 1.
 
This is insane – it’s obvious the jabs do not work on current Covid-19 variants – they probably never did work, even on the Alpha strain, and clearly cause much more harm (vaccine injuries and deaths) than good.
 
Covid-19 lockdowns and vaccines were always a corrupt money game. Told you so 29 months ago.
 
It used to be that corrupt governments and health authorities were slagging the unvaxxed as miscreants who were selfish and insensitive to the safety of the vaxxed.
Now some of the unvaxxed are retaliating, calling themselves “purebloods “and the unvaxxed “mudbloods”.
This is all divisive nonsense, encouraged by our corrupt governments, health authorities and big pharma.
 
Bottom Line:
Most of us have family and friends on both sides of the vaxxed/unvaxxed divide. It’s not a war or a contest – it’s a fraud and a disaster that will kill and injure many millions.
 
THINK ABOUT CURES.
I (and many others) have found Ivermectin is an effective cure for minor vaccine injuries such as chronic bleeding, etc. Start there.
 
More serious vaccine injuries, including an explosion of cancers, will require much more work.
 
Only the greatest of fools will take more toxic Covid-19 vaxxes – sadly – Darwin Awards.

And it’s 1 mill that will NOT die again of diabetes, cancer, cardiac arrest, Alzheimer’s and other typical end-of-natural-lifespan diseases. All told, 99.6% of all who had Covid are still alive. I leave it to you to estimate about how many 90+ year olds succumbing to Covid or other types of Flu or Common Cold in 2020 would be alive today. Not even half I guess, given that most victims were already in care homes, no longer fit enough to care properly for themselves and preparing to meet their maker in the very near future anyway. Quite probably Covid hastened their demise, but that’s not _excess_ deaths but just deaths _brought forward_ a few weeks or month.

The publication reports approximately 600 deaths attributed to influenza during the 2020-2021 flu season in the United States, which typically peaks between December and February. Compared to previous years, where the numbers in the 2019-2020 season saw roughly 22,000 deaths, and the 2018-2019 season had more at 34,000 deaths, 600 is a 97 percent drop. So why is that happening? Are the typical flu deaths being categorized as something else?

Virtually every Pneumonia and Influenza death for nearly 18 months were coded as CoViD.  As were any Upper Respiratory illness deaths.   I do not think ‘excess’ mortality is a good measure of anything.  It assumes that death rate is constant, but we have an aging population, we have a less healthy population.  There was a massive increase in drug overdoses and suicides. The vax killed how many?  To claim that the increase is attributable entirely to a disease where 90% are Asymptomatic is wrong.  Too much money involved to slow the train.  50% of hospitalized patients were killed by the ventilator in the first 3 months of 2020.

The Covid statistics were exaggerated but US excess deaths in 2020 were not. The only likely cause in 2020 was Covid. Agreed that most deaths were the elderly. Excess deaths continued through June 2022 so far. Covid is not causing the excess deaths in 2022 because the predominant Omicron strain is a coronavirus common cold with an extremely low infection fatality rate.

“The only likely cause in 2020 was Covid.”

You don’t think delayed treatment for medical issues or suicide from depression caused by the lockdowns had any impact?

I’m not saying covid wasn’t even a major contributor, but those MUST be factored in as well.

We should, also, remember the Governments refusal to provide, or even allow, early treatment for Covid to the point that it was, almost, forbidden. I can’t think of any other disease where sick people were told to stay home until they can’t breathe anymore. Insane!
Given this, many people could have died from undiagnosed flu because the doctors wouldn’t see or treat them as well as from Covid for the same reasons?
Florida had great success with Monoclonal Antibody treatment. You know how successful it was because one of the first things Biden, irrationally, did was to try to prevent states from having access to that treatment. DeSantis had to go buy his own to continue treating Covid patients. It’s like they wanted people to die.

“The Covid outbreak was definitely a pandemic under any definition.”

No, Covid-19 was a WHO scam. I called it correctly in a note published on 21Mar2020, ~6 days into the needless, destructive lockdown. Covid-19 was an illness that was only dangerous to the very elderly and infirm, but not even close to a real epidemic. Six months later on 4Oct2020, world experts wrote the same conclusion in the Great Barrington Declaration.

I wrote our politicians and media on 8Jan2021 to NOT release these toxic Covid-19 “vaccines”. These so-called “vaccines” are bio-weapons. 

In Alberta now, the leading cause of death is listed as “unknown”. It’s the Covid-19 vaxxes.

I’ve taken flu shots every year including 2019, but no longer – trust is gone.

German Report Reveals 1 in 25 Insured Individuals Treated for COVID Shot Reactions – The Vaccine Reaction
Not long ago this number was 1 in 1000 – if people keep taking these jabs it will be 1 in 1.

https://wattsupwiththat.com/2022/06/29/extreme-temperatures-linked-to-nearly-1-million-deaths/#comment-3545699
[excerpts]

For so many of our analyses on Climate and Covid, it is useful to simply use “All-Cause Total Deaths”, in part because the detailed illness data has been so corrupted. Total deaths is hard to corrupt because it is binary – a zero or a one. BE A “ONE”!
 
In Alberta and Canada there was no “Total Death Bump” (increase in the trend) in the 12 months ending 1July2020 – the end of the first “flu season” of Covid-19. None! In Alberta the average age of death attributed to Covid-19 to this date was 82 – think about what that means).
(See my paper CorrectPredictions.ca for a plot of the six-year, no-bump, death trend in Alberta and Canada to 1July2020.)
 
No Total Death Bump means no real pandemic – an illness yes, but certainly not a pandemic – for a real pandemic you’ve got to kill a lot of people. Canada did not do anything really sensible to treat Covid, except we did do early treatment, but still forbade Zinc ionophores Hydroxychloroquine and Ivermectin (due to the corrupt rat-bastards in our health system who were paid to push the toxic “vaccines” – same as the USA, the UK, and elsewhere).
 
The USA solved that (lack of total mortality) problem by paying hospitals to perform incredibly-wrong, very-late-and-extreme treatment of Covid-19 patients with remdesivir (which causes liver and kidney failure) and ventilators to finish them off. Also in New York
and nearby, patients with active Covid were put back into old-folks homes to infect them.

Based on Canada’s successful experience, ~all of these deaths were avoidable with early treatment.

Thank you Sommer – but I hardly saved any lives, including friends and family who just don’t believe it can be this incredibly insane. It’s not about poor little me, but just imagine KNOWING how this train wreck will end (millions of vaccine deaths and serious injuries), issuing warning after warning, and nobody listened. It’s Kafkaesque – on one of his really bad, totally-fubar days.
I did not publish on Covid-19 until I was certain – by ~Feb 2020 the data from the Diamond Princess cruise ship and limited other quality data (amid so much fraudulent BS) was convincing – this flu was only dangerous to the very elderly and infirm – and it was definitely NOT a pandemic. But I only had the conviction to publish on 21Mar2020 when my physician friend told me that our hospitals had been emptied for a “tsunami of Covid patients” WHO NEVER ARRIVED! I called the fraud then – it helped to recognize the propaganda patterns of the Climate scam, and then to see both the Climate and Covid scams being pushed by the same “usual suspects” at the UN, the WEF and the WHO.
I was suspicious that the Covid-19 “vaccines” had been unsafely and unethically rushed into use. I then started reading the few ethical physicians and researchers who condemned the toxic “vaccines”.
There was also some good data from other countries to compare with the USA. The USA could not have done it worse – they killed off many needlessly with their “stay home til you’re dying” nonsense, then remdesivir and ventilators. As I’ve said previously, Canada had NO total death bump vs previous years to 1July2020 – and that means there was NO real pandemic – not even close to one.
I’m just repeating everything I’ve written before, because it’s late, I need sleep (beaucoup) and I’m totally tired of this scam, this slaughter of innocents, this culling of humanity.

“Germany’s DWD Weather Service Redefines “Heat Wave”: Now 3 Consecutive Days Of Warm Weather!”

No, they haven’t done that. Firstly it is a definition used for the preparation of a particular map; there is no indication it is meant to be general. But there are two requirements:
1. If the current grid values of the temperature maximum are above this climate threshold (98th percentile for that day of the year)
2. and above 28 °C 
for 3 consecutive days or more
The first is the more exacting requirement in most places.

Still stupid.
A. In the cooler north you could have 28.1 degrees and be a heatwave but in the warmer south you could have 30deg and not be a heatwave.
B. In June you could have 28.1 and be a heatwave but in July you could have 30 degrees and not be a heatwave.

I suppose one could look at like the definition of a rogue wave: waves whose height is more than twice the significant wave height ( Hs or SWH), which is itself defined as the mean of the largest third of waves in a wave record.

In a bay with SWH of 1 foot, a rogue would only have to be 2 feet to achieve that lofty title.

The primary condition (DWD) is from distribution, ie percentile. That could give a not very hot heat wave in winter. So they add the extra requirement of 28C.

The UK Met Office definition
A UK heatwave threshold is met when a location records a period of at least three consecutive days with daily maximum temperatures meeting or exceeding the heatwave temperature threshold. The threshold varies by UK county.

According to our local TV weather the county where I live, Derbyshire, has a 1’C different definition of a heatwave than the neighbouring county. Nottinghamshire. I’m not sure how that affects the forecast as we both get the same one. I’ve never heard them forecast a heatwave in one county only. I haven’t heard them report one for only one county either.

Nick, could you explain what this means in real terms:

the current grid values of the temperature maximum are above this climate threshold (98th percentile for that day of the year

It doesn’t really make sense. Why is it that simple things — “5 days with high temperatures above 30 C” — have to become complicated things — “The map definition needs some heavy computation” — without any indication they are improving results, but are only making it more difficult for non-insiders to validate?

They are trying to implement what you expect a heat wave to mean. Something that is hot, and unusual for the location. So they define it in probability terms.

The nub of this conversation is that different weather effects can be expected in all the different climates around the world at different times and to different degrees of sensibility.

Especially if you look at the state of the weather stations used by GHCN. They claim to have over 20,000 stations, which is true; but only about 1800 of them actually have full data coverage over the 30-year range used for a baseline. That includes 1981-2010 and 1991-2020.

It might include any 30-year period, but I haven’t looked at the data in a while.

About 1200 of the stations are in the US and North America, with another bunch in Europe, Russia, China, and Australia. Most of South America is left out, as is Africa and SE and SW Asia.

Now imagine running homogenization and gridding and weighting and interpolation across that mess and pretending you know anything about the “average temperature anomaly” of the planet.

“Now imagine running homogenization and gridding and weighting and interpolation across that mess and pretending you know anything about the “average temperature anomaly” of the planet.”

I don’t imagine it. I do it, every month (eg July). Though I use raw data, not homogenised. It makes little difference; I still get the same result as GISS does a week or so later.

August 30, 2022 5:20 pm

Well, sure you would. Doesn’t mean that the result has any significance.

When calculating your baseline, what’s the limit you allow for using a station’s data? If you’re doing the August average for a station for the years 1991-2020, or whatever, what’s the most missing (-9999) months you allow before tossing the station?

Reply to  James Schrumpf
August 30, 2022 11:44 pm

I don’t calculate an average for a station. I calculate a global average by least squares fit. That yields offsets for each station, from which comes the anomaly.

GHCN has quality control on its stations. They always have enough months for the LS fit.

Nick,
After years of fiddling with Aust heat waves, I lean to a type of definition that measures how hot the days were, how long it lasted and how it compares with earlier events at that station. That is why I continue to present a salad of results for each station I analyse, including Rae and adjusted data, heatwave durations of 1, 3, 5 and 10 consecutive days plus a display of all years of data and a subset of the Top 40 years. There is enormous variation among all these displays, allowing interpretation to suit whatever floats your boat.
Weaknesses in this approach include consecutive days that rate a mention except that 1 cool day in the middle upsets it; it does not use Tmin, which could help wrt hospitalization needs; it omits factors like wind speed and humidity for comfort and fire impacts; it chooses only one heatwave a year when a year could have several; confusion of dates of heatwaves starting can happen at ends of calendar years; and more.
You reach a point where ease of computing conflicts with wider definitions, so you present what you hope is adequate of the raw essence.
Then people interpret it to suit preconceptions, which is poor science and sad. Geoff S

In that context and with that map, what would define a July heat wave in Boulder, CO vs in Elkins, WV? Elkins has a USCRN station, so its temps are well-documented.

There is actually an international standard for “heat wave”, although now being ignored. The IMO website says a heat wave is any period of 5 consecutive days for which the high temperature is 5C (9F) or more higher than the average high temperature for that day for the period 1960 – 1989. Very inconvenient for those trying to scare people. (I looked it up about 2 weeks ago – it could, of course, have been modified or disappeared between then and now.)

I doubt that any “heat wave” reported this summer met that definition.

No we don’t regularly see temperatures >30 or >35, certainly north of Watford. The south east is only 20 miles from continental Europe and regularly has weather patterns from there, both in winter and summer. It depends almost entirely on the position of the jet stream, to the north we get a hot dry summer, to the south we get a cool, wet summer. Blocking highs extend the length of the hot summer (1976, 2003) or the cold winter (1962/63; 2017/2018)

Only with great comfort can a people obsess about a meaningless few degrees of temperature increase and natural disasters which have always plagued Earth and are less common today than in many other times.
As for the theft being committed by the many corrupted crooks, it’s been seen before only it was brought on by high priests, pharaohs and other such leaders seeking to blame anything other than themselves for any and every disaster and demand sacrifice from the people to atone for their sins. Many folks, some male but mostly female were burned at the stake or hung for bad weather to atone for the sins they assumed were causing bad weather, illness and such.

Well at least it is slightly more sophisticated than the BBC’s definition of a heat wave.
There, the term heat wave is adopted if there is a hot afternoon somewhere in London or the home counties.
Summer here in central UK has been dry this year. It has been great for outdoor activities , not so good for vegetable growers though.
I am sure it will be described as the hottest year in the satellite era notionally given as 1979.onward.
That period of reflection, conveniently avoids mentioning 1976. 1976 here in the UK is still the stand out hottest, longest, driest year, in modern times, post second world war.

Summer in the UK saw 2 real heatwaves with 30C plus temperatures and high night time temps over several days.

(Between 18 and 19 July, the United Kingdom experienced its highest recorded minimum night time temperature, at 26.8 °C (80.2 °F) at Shirburn Model Farm, Oxfordshire. This is an increase of 2.9 °C from the previous record, set in Brighton in August 1990.Temperatures in many other parts of the country did not fall below 25 °C (77 °F), giving the UK its warmest ‘tropical night’ on record)

and it set a new record temperature (the previous record was broken in 33 places across the UK in the same day)

“Summer in the UK saw 2 real heatwaves with 30C plus temperatures and high night time temps over several days.”

Where I live which is almost precisely on the bounday between inner and outer London day time temperatures reached the early thirties on several days but the nightime temperatures were in the teens to low twenties. It was only on two nights between the three anticipated record breaking days that the temperatures refused to drop. Even then the park land a tenminute walk from the more urban part I live in were much cooler – day time low thirties at best. It was the UHI effect at its best.

Please do not tell me what I should have observed as I am not prepared to lie on your or anyone else’s behalf. It was hot for three days but that is not unusual in the UK – anywhere.

During the UK’s recent record breaking ‘heatwave’, temperatures at Gatwick Airport overnight barely fell below the very late twenties and yet in a rural setting less than two miles away from the airport the early morning temperatures were in the mid teens. It was overnight heat retention that assisted the record temperatures where they occurred in the UK and not climate change or a heatwave.

It would be much more helpful to the public if meteorologists stuck to studying their subjects until they become really proficient in understanding them rather than trying to scare the **** out of people by makiing claims they cannot substantiate except by lying, cheating and changing definitions to suit their ugly causes.

After that, everywhere we went from Dover to Cornwall up into Wales everyone said how wonderful the summer was and not a single complaint to be heard.

Yes, there was virtue signaling and moral panic, like the British Museum kicking everyone out at 3pm because of the heat, tossing hundreds of people out from 22c into 40c but that’s life right?

P. Gosselin: “because so many evenings were too cool to sit outside without a jacket. Moreover, there was not a single night that I found it to be difficult to sleep.”
P. Gosselin knows Germany much better than I do but I was in Germany from July 2 to July 20 this year. During that time there wasn’t a single evening when I felt that I needed a jacket. (The most northerly place I stayed in was Münster and the most southerly was Volkach, which is near to Würzburg.) For the last six nights of my holiday I stayed at St Goar on the Rhine. During that time the temperature was in the 30s for much of the day. To me it felt very uncomfortable. On the 15th it was 26 degrees at 8.30pm. On the 20th it was 26 degrees at 9pm. On the 19th I spent 5 hours cruising on the river so that I could escape the heat by staying in the air-conditioned restaurant area of the ship. And I most certainly found it difficult to sleep in the night-time temperatures. (My hotel did not have air-conditioning.) Maybe I reacted differently to Mr Gosselin as I come from Scotland and I’m not used to temperatures in the 30s but in future I will stay away from Germany in July.

Speaking of heat waves, I would like to draw attention to the serious situation in Southern China. I’m not sure that I completely agree with the media that it is the ‘worst heat wave of all time” but it is serious. The Yangtze River bed is exposed. Does anyone have a more scientific explanation as to what is causing this heat waves? Maybe the La Niña? The same question goes for Europe and the U.S. since it has been a hot summer probably not the hottest but still hot.

In fact where I live, temperatures are supposed to hit 100 degrees later even though it’s going to be September (see link below). Why is this happening? Is this a completely natural phenomenon? I miss the fall weather.

Since I retired (I worked in an air conditioned environment) I decided to acclimate myself to the heat. I’ve been sitting outside the last few summers, in the shade of course.

Of course, Sunshine ski resort was opened for July 1 canada day weekend because there was lots of snow that late first time ever.
And now 7 bears killed recently, because it’s such a cold year the mountain berry crop sucks so they are coming low and getting hit by cars and trains.
Of course the media says it’s because climate change, of course.
No one told them that colder and snowier is just weather.

Vail ski resort in Colorado, as well, had the longest ski season in its history in 2022.

“…contemplate the end of the world from my porch.” is the nicest turn of phrase I’ve read in many months. Brilliant.

Any faction that needs redefine the meaning of words has defacto lost the argument.

And FYI, the US has been in the throes of a recession since January of 2022. Ignore all Progressive arguments to the contrary.

Let me see if I’ve got this straight. Heat waves are specific to a geography, ie. if it is so many degrees hotter for a given number of days, in the spot where I’ve elected to dwell, then that is a “heat wave” which is claimed to objectively demonstrate “man made global warming.” Remarkably, my local “heat wave” may occur at temperatures demonstrably lower than the (what’s the opposite of heat wave?) measured drop in temperatures (so many degrees cooler for a given number of days) at another point on the planet.

“Existential threat” climate change, however, is documented by recording and calculating a mystical annual temperature change across the entire planet.

So heat waves are indicative of “climate change” but geographically specific, and “climate change” is non-geographically specific, but rather across-the-planet homogenized, incredibly influenced by the selection/location of measuring points, and indicative of “climate change”?

I sense a massive double-standard.

You can’t beat age and experience like Horst-
Tough choices for Germany as coal power stations return to keep people warm this winter (msn.com)
It’s called winter Gretaheads. LOL.

For 8 of Australia’s bigger cities, some with daily temperature max and mins going back before 1870, I calculated the hottest heat wave each year The heat wave was taken to be the highest average of consecutive days 1, 3, 5, and 10 days duration, each year. I then sorted all years to get the Top 40 hottest waves as well as the full set showing each year. All results are of raw data for maximum daily temperature from the official BOM web site.
For illustration, I have chosen to display here the 5-day set for 8 stations, the Top 40 hottest.
There is no strong signal shown in the full set of these graphs, all 128 of them including the adjusted AGORN-SAT series from the BOM, to indicate that here, heatwaves have become hotter, longer or more frequent.
There are several alarmist papers that claim hotter, longer and more often, but they do not have the simple data purity of my exercise. They often start at more recent dates, the often use adjusted data and importantly for this topic, they rely upon special definitions of “heatwave”.
If there is no perceptible signal in the simple raw data, why do people torture it to make dramatic headlines.
Readers of WUWT should do this exercise for your own region or city. It is quite powerful evidence of the reality of what is happening. It is very easy on Excel, no programming skill or macros needed.

I suppose it’s only a matter of time (probably next summer) before each “heat wave” gets its own name, like hurricanes and babies.
