The heresy of heat and cold deaths
A group of campaign researchers try hilariously, ineptly — and depressingly —to suppress facts
TL;DR. A blog, claiming to check facts, does not like that I cite this fact: the rising temperatures in the past two decades have caused more heat deaths, but at the same time avoided even more cold deaths. Since this inconvenient fact is true, they ignore to check it. Instead, they fabricate an absurd quote, which is contradicted in the very article they claim to ‘fact-check’.
166,000 avoided deaths
Cold deaths vastly outweigh heat deaths. This is common knowledge in the academic literature and for instance the Lancet finds that each year, almost 600,000 people die globally from heat but 4.5 million from cold.
Moreover, when the researchers include increasing temperatures of 0.26°C/decade (0.47°F/decade), they find heat deaths increase, but cold deaths decrease more than twice as much:
Or here from the article:
The total impact of more than 116,000 more heat deaths each year and almost 283,000 fewer cold deaths year is that by now, the temperature rise since 2000 means that for temperature-related mortality we are seeing 166,000 fewer deaths each year.
Climate Feedback
However, this is obviously heretical information, so the self-appointed blog, Climate Feedback, wants it purged. Now, if they were just green campaigning academics writing on the internet, that might not matter much. But unfortunately, this group has gained the opportunity to censor information on Facebook, so I have to spend some time showing you their inept, often hilarious, and mostly nefarious arguments. The group regularly makes these sorts of bad-faith arguments, and apparently appealing their Facebook inditements simply goes back to the same group. It is rarely swayed by any argument.
They never test the claim
Climate Feedback seemingly wants to test my central claim from the Lancet article that global warming now saves 166,000 people each year, from my oped in New York Post:
But notice what is happening right after the quote “Global warming saves 166,000 lives each year”. They append it with something that is not in the New York Post. You have to read much further to realize that they are actually trying — and failing — to paste in an entirely separate Facebook post, which addressed a different scientific article.
It turns out, Climate Feedback never addresses the 166,000 people saved in their main text. “166” only occurs three times in the article: twice stating my claim and once after their main text in a diatribe by an ocean-physics professor, complete with personal insults. In it, the professor doesn’t contest the 166,000 avoided deaths. Instead, he falsely claims that I am presenting the 166,000 as the overall mortality impact of climate change, which is absurd: anyone reading my piece understand that I’m talking about the impact of temperature-related mortality.
Perhaps most tellingly, Climate Feedback has asked one of the co-authors of the 166,000 Lancet study (as they also very proudly declare in their text). And this professor, Antonio Gasparrini, does not only not challenge but doesn’t even discuss my analysis of the 166,000 avoided deaths.
Climate Feedback not only doesn’t present any reasonable argument against the 166,000 avoided deaths. It has actually asked one of the main authors of the study to comment and they have nothing.
In conclusion, Climate Feedback simply has no good arguments against the 166,000 people saved, and yet they pillory my work publicly in an attempt to censor data they deem inconvenient. . That academics play along in this charade of an inquisition dressed up ‘fact-check’ is despicable.
Rest of Climate Feedback’s claim is ludicrously wrong
So, beyond the claim of 166,000, Climate Feedback is alleging that I say the following: “those claiming that climate change is causing heat-related deaths are wrong because they ignore that the population is growing and becoming older.”
This is a fabricated quote. I never say this. Climate Feedback has simply made up a false statement, dressing it as a quote of mine, even though I never claimed anything like this. This is incredibly deceptive: it is ludicrous to insist that I should argue that it is wrong to claim “climate change is causing heat-related deaths.” I simply do not argue that “climate change is not causing heat-related deaths”
Up above I exactly argued that climate change causes more heat deaths. My graph shows that climate change causes more heat deaths.
And I even point out exactly that the temperature increases cause heat deaths in my New York Post piece:
“As temperatures have increased over the past two decades, that has caused an extra 116,000 heat deaths each year.” Sorry, Climate Feedback, but the rest of your claim is straight-out, full-on stupid.
Evaluation of Climate Feedback’s review
So Climate Feedback is simply wrong in asserting that I somehow say climate change is not causing heat-related deaths — because I do say that, even in my New York Post article:
Climate Feedback doesn’t show anywhere in their main text how the 166,000 avoided deaths are wrong. They even ask one of the main authors of the study, and that professor says nothing.
Conclusion
Climate Feedback’s deceptive hit job is long on innuendo and bad arguments (see a few, further examples below). But the proof really is in the pudding.
They make two central arguments. First, that my claim of “Global warming saves 166,000 lives each year” is incorrect. Yet, they never address this in their main text. And while they get information from one of the main authors of the Lancet study that is the basis for the 166,000 lives saved, they get no criticism of the argument.
Second, they assert that I somehow say that it is wrong to claim climate change is causing more heat-related deaths, which is just ludicrous because I make that very point, even in my New York Post article:
Verdict: Climate Feedback is fundamentally wrong in both their two main claims.
Additional point: It really shouldn’t be necessary to say, but you can’t make a ‘fact-check’ page, write page after page of diatribe, ignore the first main point and bungle the other main point, and then hope at the end nobody notices, and call my arguments wrong. Or, at least, you shouldn’t be able to get away with such nonsense.
Two examples of the inadequate arguments in the rest of Climatefeedback
Lomborg doesn’t have a time machine
Climate Feedback asks professor Gasparrini, co-author of the Lancet study above. He doesn’t cover anything on the 166,000 deaths avoided. Instead, his text entirely discusses a 2016 WSJ article where I used his 2015-article but he criticizes me for not citing his 2017 article:
The reason I didn’t cite his 2017-article is of course that I didn’t have access to a time machine when I wrote my article in 2016.
Indeed, I have corresponded with Professor Gasparrini several times later about his 2017-article. And yes, his 2017-study indeed shows that at very high emissions, additional heat deaths will likely outweigh avoided cold deaths towards the end of the century. But his study also shows that all regions see additional heat deaths vastly exceeded by extra avoided cold deaths from the 1990s to the 2010s — the exact point I’ve made here.
Serious academics take into account population growth and aging
In a refreshing comment, Climate Feedback asks Philip Staddon, Principal Lecturer in Environment and Sustainability from the University of Gloucestershire to chime in. He says, that I’m wrong to criticize the lack of standardization from population growth and aging, because clearly “all serious academic research already takes account of population growth, demographics and ageing”:
I, of course, entirely agree with Staddon, that all serious academic research should do that. But the research that I have criticized has exactly not done so, resulting in unsupported claims. So, for instance, in the Facebook post that Climate Feedback discusses, I show how CNN believes that a study shows a 74% increase caused by the climate crisis:
This is based on not adjusting for population and age, and is actually from the press release of the paper (and in table S6 in the paper).
Likewise, Staddon might have noticed that a very high-profile editorial in the world’s top medical journals made that very amateurish mistake. They argue that temperature increases over the past 20 years have increased deaths among people 65 and older:
But they cite numbers that are not adjusted for age or population — indeed the world’s population of people above age 65 has increased almost as much:
I absolutely agree with Principal Lecturer Philip Staddon on the necessity of making sure that good arguments in the public sphere are adjusted for population and aging before blaming climate. Unfortunately, they often aren’t

Misinformed: Hyped heat deaths and ignored cold deaths

From the Fraser Institute
Whenever there’s a heatwave—whether at home or abroad—the media loves to splash it. Politicians and campaigners then jump in to warn that climate change is at fault, and urge us to cut carbon emissions. But they are only telling us one-tenth of the story and giving terrible advice.
Global warming indeed causes more heat waves, and these raise the risk that more people die because of heat. That much is true. But higher temperatures also cause a reduction in cold temperatures, reducing the risk that people die from the cold. Almost everywhere in the world—not just Canada—cold kills 5-15 times more people than heat.
Heat gets a lot of attention both because of its obvious link to climate change and because it is immediately visible—meaning it is photogenic for the media. Heat kills within a few days of temperatures getting too high, because it alters the fluid and electrolytic balance in weaker, often older people.
Cold, on the other hand, slowly kills over months. At low temperatures, the body constricts outer blood vessels to conserve heat, driving up blood pressure. High blood pressure is the world’s leading killer, causing 19 per cent of all deaths.
Depending on where we live, taking into account infrastructure like heating and cooling, along with vehicles and clothes to keep us comfortable, there is a temperature at which deaths will be at a minimum. If it gets warmer or colder, more people will die.
A recent Lancet study shows that if we count all the additional deaths from too-hot temperatures globally, heat kills nearly half a million people each year. But too-cold temperatures are more than nine-times deadlier, killing over 4.5 million people.
In Canada, unsurprisingly, cold is even deadlier, killing more than 12 times more than heat. Each year, about 1,400 Canadians die from heat, but more than 17,000 die because of the cold.
Every time there is a heatwave, climate activists will tell you that global warming is an existential problem and we need to switch to renewables. And yes, the terrible heat dome in BC in June 2021 tragically killed 450-600 people and was likely made worse by global warming. But in that same year, the cold in BC killed 2,500 people, yet these deaths made few headlines.
Moreover, the advice from climate activists—that we should hasten the switch away from fossil fuels—is deeply problematic. Switching to renewables drives up energy prices. How do people better survive heat? With air conditioning. Over the last century, despite the temperature increasing, the US saw a remarkable drop in heat deaths because of more air conditioning. Making electricity for air conditioning more expensive means especially poorer people cannot afford to stay cool, and more people die.
Likewise, access to more heating has made our homes less deadly in winter, driving down cold mortality over the 20th century. One study shows that cheap gas heating in the late 2000s saved 12,500 Americans from dying of cold each year. Making heating more expensive will consign at least 12,500 people to die each year because they can no longer afford to keep warm.
One thing climate campaigners never admit is that current temperature rises actually make fewer people die overall from heat and cold. While rising temperatures drive more heat deaths, they also reduce the number of cold deaths — and because cold deaths are much more prevalent, this reduces total deaths significantly.
The only global estimate shows that in the last two decades, rising temperatures have increased heat deaths by 0.21 percentage points but reduced cold deaths by 0.51 percentage points. Rising temperatures have reduced net global death by 0.3 per cent, meaning some 166,000 deaths have been avoided. The researchers haven’t done the numbers for Canada alone, but combined with the US, increased temperatures have caused an extra 5,000 heat deaths annually, but reduced the number of cold deaths by 14,000.

If temperatures keep rising, cold deaths can only be reduced so much. Eventually, of course, total deaths will increase again. But a new near-global Nature study shows that, looking only at the impact of climate change, the number of total dead from heat and cold will stay lower than today almost up to a 3oC temperature increase, which is more than currently expected by the end of the century.
People claim that we will soon be in a world that is literally too hot and humid to live in, using something called the “wet bulb” temperature. But under realistic assumptions, the actual number of people who by century’s end will live in unlivable circumstances is still zero.
The incessant focus on tens or hundreds of people dying in for instance Indian heatwaves makes us forget that even in India, cold is a much bigger challenge. While heat kills 89,000 people each year, cold kills seven times more at 632,000 every year. Yet, you would never know with the current climate information we get.
Hearing only the alarmist side of heat and cold deaths not only scares people—especially younger generations—but points us toward ineffective policies that drive up energy costs and let more people die from lack of adequate protection against both heat and cold.

We need to get smart about climate

APPEARED IN THE FINANCIAL POST
By: Bjørn Lomborg
Canada’s chattering classes claim that climate change is one of the country’s pre-eminent threats. This is extraordinary. Canada is experiencing a productivity slowdown, the worst decline in living standards in 40 years, and growth rates that lag most developed economies. Geopolitical threats loom, the healthcare system is under stress and education is faltering. Yet the federal government has spent or committed more than $160 billion on climate initiatives since 2015, and is funneling $5.3 billion to help poor countries respond to climate change.
Like most nations, Canada faces tough decisions in coming decades. Resources spent on climate will not be not available for health, education, security or boosting prosperity.
Global warming is a real problem. Science has shown quite clearly that more CO₂, mostly from fossil fuel use, increases global temperatures. Climate economics has shown how this brings both problems and benefits (for instance, more deaths caused by heat, fewer by cold) but, overall, more problems than benefits. More CO₂ means higher social costs, so reducing CO₂ does have real benefits.
But climate policies also have costs. They force families and businesses to use more expensive energy, which slows economic growth. You might have heard otherwise but if the new ways really were cheaper, no regulations or mandates would be needed.
If climate change were treated like any other political issue, we would openly recognize these trade-offs and try to balance them to get the most climate benefits for the least cost, recognizing that climate policies need to compete against many other worthy policies.
But in two important ways the climate conversation has gone off the rails.
First, people say — wrongly — that global warming is an existential challenge, risking the end of mankind. Of course, if the world is about to end, it follows that any spending is justified. After all, if a world-obliterating meteor is hurtling towards us, we don’t ask about the costs of avoiding it.
Second, it is also often claimed — somewhat contradictorily — that the green transition will make energy cheaper, societies safer and everyone richer. In this “rainbows and unicorns” scenario, there are no trade-offs and we can afford climate policy and everything else.
Both claims are repeated ad nauseam by Canadian politicians and activists and spread by media hooked on selling climate catastrophes and green utopias. But both are quite untrue.
That is why I’m writing this series. I will outline how many of the most sensationalist, scary climate stories are misleading or wrong and ignore the best climate science. Being data-driven, I will show you this with the best peer-reviewed data and numbers.
So: Is climate change the world’s all-encompassing problem today? One way to test this is to look at extreme weather, which we constantly hear is having an ever-larger impact on our societies. But the data paint a very different picture (see chart).
We have good evidence for the number of people killed in climate-related disasters, i.e., floods, storms, droughts, and fires. (We’ll look at temperature deaths next week.) A century ago, such disasters routinely killed hundreds of thousands, even millions of people in a single disaster. On average, about half a million people a year died in such disasters. Since then, the death toll has declined precipitously. The last decade saw an average of fewer than 10,000 deaths per year, a decline of more than 97 per cent.
Of course, over the past century the world’s population has quadrupled, which means the risk per person has dropped even more, and is now down by more than 99 per cent. Why this great success story? Because richer, more resilient societies with better technology and forecasting are much better able to protect their citizens. That doesn’t mean there is no climate signal at all, but rather that technology and adaptation entirely swamp its impact.
In the same way, climate’s impact on overall human welfare is also quite small. In proportion to the total economy, the cost of climate-related disasters has been declining since 1990. Looking to the future, the best estimates of the total economic impact of climate change come from two major meta-studies by two of the most respected climate economists. Each shows that end-of-century GDP, instead of being 350 per cent higher, will only be 335 per cent higher.
“Only” becoming 335 per cent richer is a problem, to be sure, but not an existential threat. Despite that, as this series will show, many of the most draconian climate policy proposals so casually tossed around these days will do little to fix climate but could dramatically lower future growth and the opportunities of future generations.
We need to get smart on climate. This series will map out how.
