Claim: 52F – 59F Annual Average is a “Fundamental” Climate Constraint

Guest essay by Eric Worrall

Despite humans being tropical apes, we apparently find it very difficult to survive outside of temperate zones where average annual temperature ranges from 52F – 59F (11C-15C).

Climate change could bring near-unliveable conditions for 3bn people, say scientists

Each degree of warming above present levels corresponds to roughly 1bn people falling outside of ‘climate niche’

Steven Bernard, Dan Clark and Sam Joiner

Up to 3bn out of the projected world population of about 9bn could be exposed to temperatures on a par with the hottest parts of the Sahara by 2070, according to research by scientists from China, US and Europe.

However, rapid reductions in greenhouse gas emissions could halve the number of people exposed to such hot conditions. “The good news is that these impacts can be greatly reduced if humanity succeeds in curbing global warming,” said study co-author Tim Lenton, climate specialist and director of the Global Systems Institute at Exeter university.

The report highlights how the majority of humans live in a very narrow mean annual temperature band of 11C-15C (52F-59F). Researchers noted that despite all innovations and migrations, people had mostly lived in these climate conditions for several thousand years.

“This strikingly constant climate niche likely represents fundamental constraints on what humans need to survive and thrive,” said Professor Marten Scheffer of Wageningen University, who co-ordinated the research with his Chinese colleague Chi Xu, of Nanjing University.

The abstract of the study;

Future of the human climate niche

 Chi Xu, Timothy A. Kohler, Timothy M. Lenton, Jens-Christian Svenning, and Marten Scheffer

All species have an environmental niche, and despite technological advances, humans are unlikely to be an exception. Here, we demonstrate that for millennia, human populations have resided in the same narrow part of the climatic envelope available on the globe, characterized by a major mode around ∼11 °C to 15 °C mean annual temperature (MAT). Supporting the fundamental nature of this temperature niche, current production of crops and livestock is largely limited to the same conditions, and the same optimum has been found for agricultural and nonagricultural economic output of countries through analyses of year-to-year variation. We show that in a business-as-usual climate change scenario, the geographical position of this temperature niche is projected to shift more over the coming 50 y than it has moved since 6000 BP. Populations will not simply track the shifting climate, as adaptation in situ may address some of the challenges, and many other factors affect decisions to migrate. Nevertheless, in the absence of migration, one third of the global population is projected to experience a MAT >29 °C currently found in only 0.8% of the Earth’s land surface, mostly concentrated in the Sahara. As the potentially most affected regions are among the poorest in the world, where adaptive capacity is low, enhancing human development in those areas should be a priority alongside climate mitigation.

My home in Queensland, Australia, experiences an average annual temperature of around 77F (25C), 18F above the alleged human climate niche.

Last time I checked our state enjoyed a prosperous agriculture and mining economy, with vibrant cities full of happy people who mostly don’t own heavy overcoats.

The far North of Australia which includes some of our most prosperous agricultural and mining regions, are even hotter.

Then you have nations like Singapore, Indonesia, Kenya, and Colombia, all established or up and coming economic success stories which sit right on the equator. Venezuela used to be successful, but their problems have nothing to do with global warming.

These glaring exceptions to the “human environmental niche” should be considered strong evidence that prosperity is possible outside the 52F – 59F zone where the bulk of people live. But the authors dismiss this, arguing there is a ongoing causal element to human distribution.

The Question of Causality.

Why have humans remained concentrated so consistently in the same small part of the potential climate space? The full complex of mechanisms responsible for the patterns is obviously hard to unravel. The constancy of the core distribution of humans over millennia in the face of accumulating innovations is suggestive of a fundamental link to temperature. However, one could argue that the realized niche may merely reflect the ancient needs of agrarian production. Perhaps, people stayed and populations kept expanding in those places, even if the corresponding climate conditions had become irrelevant? Three lines of evidence suggest that this is unlikely, and that instead human thriving remains largely constrained to the observed realized temperature niche for causal reasons.

First, an estimated 50% of the global population depends on smallholder farming (19), and much of the energy input in such systems comes from physical work carried out by farmers, which can be strongly affected by extreme temperatures (20). Second, high temperatures have strong impacts (2123), affecting not only physical labor capacity but also mood, behavior, and mental health through heat exhaustion and effects on cognitive and psychological performance (202425). The third, and perhaps most striking, indication for causality behind the temperature optimum we find is that it coincides with the optimum for economic productivity found in a study of climate-related dynamics in 166 countries (12). To eliminate confounding effects of historical, cultural, and political differences, that study focused on the relation within countries between year-to-year differences in economic productivity and temperature anomalies. The ∼13 °C optimum in MAT they find holds globally across agricultural and nonagricultural activity in rich and poor countries. Thus, based on an entirely different set of data, that economic study independently points to the same temperature optimum we infer.

Altogether, it seems plausible that the historically stable association between human distribution and temperature reflects a causal link rather than a legacy, contingent on ancient patterns reflecting agrarian needs or still-more-ancient hunter-gatherer preferences. This supports the view that the historically stable and tight relationship of human distribution to MAT represents a human temperature niche reflecting fundamental constraints on human populations.

I mean I guess its possible all this mild weather is bad for my health. Perhaps all the comfortable year round temperatures and our harsh diet of BBQ meat, fresh salad, beer, beach parties and outdoor living all year round will eventually finish us. But in my opinion the authors need to present stronger evidence than a demographic map, and a failure to address exceptions to their environmental niche hypothesis.

The huge majority of people i know spends tons of money to spent their holidays in warmer regions (and the only reason they spent their holidays in colder regions is skiing)
and those regions are usually the most frequented by tourism,
be it in Asia,Europe,America.

Even the only communist country that didn’t look like it got its life sucked out by a grey agony is Cuba (and that’s probably the reason why they got along without any significant democide or mass starvation which are integral part of communism)

Either people are generally suicidal or climate science fiction is full of assholes.

Yup … that must explain why all the northern tier states in the USA are losing their population to the southern tier states … they’re all trying to escape those “ideal temperatures” up north. Here in Florida alone we’ve gained nearly 3 million more residents than we had in the 2010 census. Everybody knows it hot in Florida.

Oh, and where did the human species arise? Yup, in hot-as-hell east Africa.

And where on the planet did civilization and agriculture first arise? Yup again, in the hot-as-hell “Fertile Crescent” of the deserts of present day Iraq, followed by the cultures of the Egyptians, Hittites, etc. of – you guessed it, the hot-as-hell Sahara desert and Sinai desert.

Ah, the Little Ice Age, where women wore NINE CONFOUNDED PETTICOATS, plus a forepart (underskirt) and an overskirt, plus the shift under it all – and this was ONLY so that they could stay warm once they moved away from the fireplace. I made one of those get-ups for a Ren Faire event and was glad I did, because the temperature plummeted on that particular day from 72F to about 45F, with a cold blast that also brought us drifts of rain. I was, at least, warm under all that puffery.

And those “pumpkin pants” that men wore? Same thing: filled with an insulating material such as oats or wheat (yes, grain does do that) to keep warm, in addition to woolen hosen and leather boots that went up over the knees. And that also includes the undershirt, the jerkin, the long sleeves on the bodicer (borrowed from women’s clothing) and a long cape that was lined to keep the wearer WARM.

Yes, it was quite a “golden age”, as long as the fires – which are full of “golden” flames – kept burning.

I read a book a couple years ago, can’t recall the title just now, about the initial European colonization of North America in the late 16th/early 17th century. The author’s main thesis was that Europeans, particularly from the British Isles, Spain, and France, all enjoyed relatively mild winters in their homelands due the effects of the Gulf Stream. They generally assumed that what later became the northeastern and mid-Atlantic United States, and the maritime provinces of Canada, being on the same latitudes as their homes in western Europe, would have a similar climate.

Thus when the came to colonize North America they suffered a rude awakening because of the very cold continental climate there, which was of course exacerbated by the Little Ice Age. Consequently most of the European colonists starved and froze, with failed and nearly failed colonies even in relatively southern and mild weather areas of Virginia (the nearly failed Jamestown colony with its infamous “starving time”, and North Carolina (the failed Roanoke colony). We don’t think of the mid-Atlantic as being a frigid climate -but it was in 1600 +/-.

Increases in temperature can also create a severe need for large pitchers of iced tea with lemon slices and cookies on the side, or c-c-c-cold soda with freshly popped popcorn. I can personally confirm that myself.
Also, increases in temperature tend to bring out the outdoor cooking crowd, whose pursuit of bounty knows no boundaries, including the consumption of barbecue ribs and potato salad.

I’ll worry about what the warm-mongers say just as soon as there is any human who lives in the global average temperature—which requires some human other than any human who has ever lived so far.

Since the global average temperature falls between 52F and 59F, doesn’t that mean that the entire globe is the preferred average temperature for humans? Funny things these “averages.”

I’m not a climatologist, but what happens if you factor ‘availability of water’ into analyzing where people live? Does temperature retain any significance for the majority if you do?

While I’ve been alive, world population has gone from 2.5 billion to 7.9 billion. It seems to me that the best metric to graph that against is….hydrocarbon consumption. What is the implication?

And why is it so hard to accept that as life on this planet seems suicidal in sequestering CO2 as oil and coal making it unavailable for more life, that humans may have evolved to be the species that returns this trapped carbon to the carbon cycle making it available for more life?

After all, the 20 ton dinosaurs lived when atmospheric CO2 was many times what it is today; ammonites grew to 8 feet, not 8 inches. If scientists at Exeter university had a vision beyond ‘man is bad’ they might grasp the implications.

The one thing to learn in weather, biodiversity, horticulture, paleontology, geology, volcanology, solar, plate tectonics, climatology, astrology is most processes are not fundamentally constant.

  • Weather involves cycles & chaos.
  • Pick a place and see the major climate shifts, changes in biodiversity.
  • Paleontology required extreme events to cover & preserve small & large skeletons with a lot of silt in a small amount of time.
  • Geology involves changes overtime as it was weathered, moved up/down, earthquakes, extreme events do most of the damage in short intermittent bursts.
  • Volcanoes have not been contant & predictable.
  • Solar activity goes in cycles with direct & indirect effects (irradiance, sunspots, solar winds deflecting cosmic rays that influence clouds).
  • Stars, galaxies & zodiacs (star signs) have shifted in position over time (not quite the same position for the same time of year). Explodes, implodes, collisions.

Lets check the climate constants:

  • Temperature has changed independent of CO2 & other GHG with many extremes.
  • MSL & snow/ice cover have constantly changed with major changes during human history of many metres.
  • water as a GHG varies the warming/cooling effect depending on location, time of day, time of year.
  • plant absorption & growth depends on location, temperature, rainfall, humidity, soil composition, fertilisation, root competition, mulch, drainage, shading.
  • If you build on sand/silt your subject to land sinking. Especially if you pump water from beneath your feet.
  • Desserts were once green and changed long before GHG emissions.

We are a tiny influence on the universe around us.

All this pontification about the ideal temperature range for humans! What do humans actually prefer? Someone should make a global survey of air conditioning settings around the world. This will show the range of temperatures actually preferred by humans.

And a great deal depends on what said humans are adapted to. Winter in the north usually comes with a few mild thaw days, everyone will don shorts and sandals and strut around in !3C because compared to last week’s -013C it feels tropical. And the opposite also applies, 10C feels bone-chilling if you are accustomed to 25C+.

Humans tend to adapt quickly, too. I was born in Arizona, but lived in New Hampshire for a few years. Visiting my family for the Christmas holidays, I ran around in just shorts. (Shirt and sandals if I went into public.)

Now I feel chilly again when the thermometer dips below 70…

Just considering some of the cradles of civilisation:

Egypt, Cairo MAT ~22°C
Mesopotamia, Baghdad MAT ~25°C
Indus valley, Lahore MAT ~24°C
Aztec, Mexico City MAT ~16°C
Ancient Peru, Chiclayo MAT ~21°C

…back to the drawing board professor.

November 2, 2021 3:37 pm

Of course that “study” is nonsense, but…

Indeed there is a 3°C range where people are most comfortable. Outside that range there are more premature deaths, about 10 times more to the cold side than to the warm side…

The funny thing is that such a 3°C range is different for any town or country where you live…

Keatinge e.a. have examined that already in 2000, be it only for summer temperatures:

Results: Mortality was lowest at 14.3-17.3°C in north Finland but at 22.7-25.7°C in Athens. Overall the 3°C minimum mortality temperature bands were significantly higher in regions with higher than lower mean summer temperatures”

Conclusions: Populations in Europe have adjusted successfully to mean summer temperatures ranging from 13.5°C to 24.1°C, and can be expected to adjust to global warming predicted for the next half century with little sustained increase in heat related mortality.”

I only wonder how people adapt to a range where they live: is it by genetics, or simply because people adapt in a few days or weeks to another climate? I suppose more the latter: lots of people here get a new home in the far south of Spain when pensioning and get a long pleasant rest of their life by moving from rainy Belgium at average 11°C to 20°C in south Spain…

A naked human dies of exposure in temperatures less than 80-85 F.

We heat/ cool our houses to 70-75 F. Trees turn their leaves to maintain a temperature of 70-75 F.

Humans can only survive temperatures of 52-59 F because of the domestication of fire.

Human habitation depends much more on the availability of water, not temperature.

Ed Fox
November 2, 2021 3:48 pm

Most cities of the world are located on water for transportation and drinking.

This limits human population, due to lack of fresh water in the horse and polar latitudes.

Temperature is simply an effect, not a cause of human civilization.

Regardless of temperature, if the water supply to a town dies the town dies.

The Fertile Crescent and Egypt were the centre of the developed world for millennia. Baghdad has an average high in August of 110 F, and 60 in January. Average daily temperatures from 50 to 95 F. Cairo is not as hot, with daily means from 57 to 83 F. They are the two largest Arab cities by population, 8-10 million.

Thriving areas of the ancient world because of warm to hot and dry climates with irrigation leading to an abundance of food, usually.

Greece and Rome prospered because of trade. Rome’s daily mean varies from 45 to 76, 59.5 F annually and most likely warmer during the RWP.

It seems that only recently have the cooler regions of Europe and North America, and more recently, China and Japan, become manufacturing power houses. Its probably not a coincidence that North England has average highs of 45 F in winter to 70 F in Summer and was the centre of the Industrial Revolution. Much easier to go to work in a factory when its cold outside.

November 2, 2021 4:10 pm

The report highlights how the majority of humans live in a very narrow mean annual temperature band of 11C-15C (52F-59F). Researchers noted that despite all innovations and migrations, people had mostly lived in these climate conditions for several thousand years.

Ever since fire was invented. Without fire or modern alternatives, not so much.

Say 20-25C (70-75F). Colder at night if you have a good blanket.

You want to see real climate migration, turn off all the fossil fuels.

In the S.E. of England, my central heating functions in the range of 19ºC – 20ºC. If it’s below around 15ºC outside I’ll put a sweater (appropriate term) on to keep me warm.

Were my family and I able to comfortably survive in a temperature of 11ºC – 15ºC I would set my central heating to that temperature. It would be a lot cheaper for me.

November 2, 2021 4:48 pm shows the average CONUS temperature (based on 1970-2000) at 52.7F, right in the 52-59 range. But the only states averaging between 52.0 and 59.0 in that period were Delaware, Kansas, Kentucky, Maryland, Missouri, New Jersey, New Mexico, North Carolina, Tenessee, and Virginia. California barely missed the cut (59.4), but it’s apparent that the CONUS population is not clinging to the ten states in the middle.

Nor do the population in those 10 states experience 52-59. At 55.6F Kentucky would seem to be right in the middle of the supposed butter range (and as the #15 state, it’s clear that more states are too cold than too warm for this metric). Clicking on Kentucky at the same sites shows every listed city in Kentucky has an average annual high above 59 and an average annual low below 52. Of what significance is the average when the average day is both too hot and too cold for the supposed optimal range. More to the point, like pretty much everywhere on earth with an “average” temperature in the 50s, it’s a temperate region with *seasons*. Going to another site I see that in the most populous city in Kentucky (Louisville) the average high in July is 89F and the average low in January is 27F. (Individual days will get hotter and colder than this, of course).

So despite being smack in the middle of a “narrow average temperature band”, the monthly averages for the biggest city in the state vary by over 60F between the highest average high and the lowest average low. The modest impacts of the modern warming period are hardly noticeable set against the usual variability of days and seasons, hardly suggestive of a “causal niche” confining humans to the 50s that most Kentuckians aren’t actually in when outdoors, and are practically never in when indoors.

The logic is simple and irrefutable:

Actually, beer can keep just fine down to about 34F, but then it’s too damn cold outside to enjoy it.

The ignorance of the history of the species Homo sapiens on Earth that is displayed by Chi Xu, et. al, and in turn parroted by authors Steven Bernard, Dan Clark and Sam Joiner in their article, is PHENOMENAL!

So far, the earliest finds of modern Homo sapiens skeletons come from Africa. They date to nearly 200,000 years ago on that continent. They appear in Southwest Asia around 100,000 years ago and elsewhere in the Old World by 60,000-40,000 years ago.

In comparison, the last glacial interval on Earth started about 110,000 years ago (during the Pleistocene) and ended about 15,000 years ago.

So Homo sapiens (ie., humans) have in fact survived/adapted to both glacial and interglacial conditions over the last 200,000 years, even without any use of technology (e.g., environmental control such as HVAC).

And the above cited authors are so bold/ignorant as to assert the species would find it very difficult to survive outside of zones where average annual temperature ranges from 52F – 59F (11C-15C) as seen over the last “several thousand years“.

No further comment is necessary.

November 2, 2021 6:23 pm

You have got to be kidding. That’s 11 to 15 DegC. In Queensland, we only get that in the depths of winter. I would die living in such a cold climate.
With recent global cooling, I installed a wood heater. We use it up to 20 DegC.

We had a nice warm spell recently with temps around 35 DegC (95 F), go a lot of yard work done around the house, went on 20 km bike rides with wife, long walks.

Hot for me is 42DegC (108 F)

Therefore under the logic of these people it was actually an act of human kindness to move people from Hot locations to Not Hot locations.

At best there is a degree of arrogance in play with this report. At worse it is an attempt to diminish the cultural and social achievements of all those people who do not live in the ‘correct’ 52-59 regions.

Remember, there are some places in the world that remove ‘black’ characters from movie posters.

Prior to the industrial revolution, many people living in the colder regions died young, barely surviving the harsh winters, whilst living in abject poverty.

I have no evidence for this, I think it’s likely the harsh winters and lack of sustenance were the drivers for innovation that led to the industrial revolution.

Post-industrial revolution, people live longer, eat better and have the freedom to pontificate about the ideal temperature being so low we need clothing and heating to survive

It sounds to me, like a rehash of Sherlock Holmes observation that “once you have eliminated the impossible, what remains, no matter how unlikely, must be the truth.” Unfortunately, the obvious flaw in Sherlock’s reasoning is that you can never eliminate every possible causation and therefore, the impossible. All these apparatchiks have done, is picked on a few straw men in order to say they have eliminated the impossible, and what they have left – cooler weather – is the only possible answer.

How this can pass for science, as opposed, say, to an op ed in New Scientists, beggars belief.

Someone please inform me WHERE do those numbskulls get that twaddle?

If we’re so very, very vulnerable to walloping highs and lows in temperature, how come people go skiing, snowshoeing, and sledding in the winter, and how come people go running off to beaches where they can wear skimpy “clothing” in the heat of a sunny day?

Please explain that to me, because I have managed to survive all the hellishly cold winters that the Midwest has ever had to offer since I was 5 years old and we moved from the sandy plains of Brownwood, TX to central Illinois. I can confirm that being stationed at NAVSTA Great Lakes in the winter is ABSOLUTELY NO FUN. It was misery in 1972 and you can ask anyone – including any recruits from sunny climes – just how much fun it is NOT!! Even so, we all managed to survive, and even the oreboat people who move stuff from the Mesabi taconite digs (shut down now because of Covid stuff) to other places functioned managed to somehow survive the beastly cold of the Great Lakes, never mind our surviving the beastly heat and humidity of Chicago-area summers.

So this is TOTALLY BOGUS, MAN!!!!

“Why have humans remained concentrated so consistently in the same small part of the potential climate space?”

Because that is where the water is (mostly near the sea). People need water to drink, grow crops and run industries. Rivers and seas are also a significant factor in World trade. People live better if they trade with each other.

Fortunately, global warming is meant to make the Earth wetter so an increase in temperature will not kill us all.

Anyway, the idea that the average temperature is relevant is daft. A hot country doesn’t become more habitable just because it has a couple of months at -20 every year.

Mad Dogs and Englishmen by Noel Coward

In tropical climes there are certain times of day
When all the citizens retire
To tear their clothes off and perspire.
It’s one of those rules that the greatest fools obey,
Because the sun is much too sultry
And one must avoid its ultry-violet ray.
The native grieve when the white men leave their huts,
Because they’re obviously definitely nuts!
Mad dogs and Englishmen
Go out in the midday sun,
The Japanese don’t care to.
The Chinese wouldn’t dare to,
Hindus and Argentines sleep firmly from twelve to one.
But Englishmen detest a siesta.
In the Philippines
There are lovely screens
To protect you from the glare.
In the Malay States
There are hats like plates
Which the Britishers won’t wear.
At twelve noon
The natives swoon
And no further work is done.
But mad dogs and Englishmen
Go out in the midday sun.
It’s such a surprise for the Eastern eyes to see
That though the English are effete,
They’re quite impervious to heat,
When the white man rides every native hides in glee,
Because the simple creatures hope he
Will impale his solar topee on a tree.
It seems such a shame
When the English claim
The earth
That they give rise to such hilarity and mirth.
Mad dogs and Englishmen
Go out in the midday sun.
The toughest Burmese bandit
Can never understand it.
In Rangoon the heat of noon
Is just what the natives shun.
They put their Scotch or Rye down
And lie down.
In a jungle town
Where the sun beats down
To the rage of man and beast
The English garb
Of the English sahib
Merely gets a bit more creased.
In Bangkok
At twelve o’clock
They foam at the mouth and run,
But mad dogs and Englishmen
Go out in the midday sun.
Mad dogs and Englishmen
Go out in the midday sun.
The smallest Malay rabbit
Deplores this foolish habit.
In Hong Kong
They strike a gong
And fire off a noonday gun
To reprimand each inmate
Who’s in late.
In the mangrove swamps
Where the python romps
There is peace from twelve till two.
Even caribous
Lie around and snooze;
For there’s nothing else to do.
In Bengal
To move at all
Is seldom, if ever done.
But mad dogs and Englishmen
Go out in the midday
Out in the midday
Out in the midday
Out in the midday
Out in the midday
Out in the midday
Out in the midday sun.

Taking at face value the commonly-cited 2 degree C increase in average global temperature expected to occur in the next century (next 50 years, next 9.5 years, whatever…the goalposts are endlessly moving), such an increase would be the equivalent of moving about 173 statute miles due south (in the northern hemisphere). So if you moved 173 miles south of wherever you are now (excluding people in places like Houston or New Orleans, who would drown in the Gulf of Mexico), would you starve to death as a result of no longer being able to grow food, or instantly burst into flames, or become a victim of “extreme weather?” Hardly.

The “climate change” that should be feared is global COOLING. I’ll see your dinosaur paradise and raise you half a continent buried under a mile of ice. We can easily adapt to warming equivalent to taking a short drive south today, but significant cooling would shorten growing seasons, reduce food availability, and possibly cause the very social unrest that “warmists” constantly fantasize will result “any time now” from a negligible increase in temperature.
