I read today that the EU is using an estimate of US$68 per tonne of CO2 emissions for the purported cost of the damages done by CO2. This is known by a Newspeak term as the “Social Cost Of Carbon”.
It made me wonder—using this estimate, what is the overall total estimated damage done by humans from emitting CO2?
The answer is $97 TRILLION dollars since 1950.
YIKES! That’s about five times the 2020 US Gross Domestic Product (the value of everything produced in the US during that year).
So I thought I’d take a look at the various largest weather-related disasters. I got the big-disaster data from Wikipedia here and arranged it by type of disaster. All values are in 2020 dollars, that is to say, they’re adjusted for inflation. Here is the result.

Hmmm … no matter how you slice it, that’s less than two trillion dollars …
Now, to be sure, there must be a variety of smaller disasters that didn’t make the list. So let’s be conservative, and call the disaster total four times that, or $8 trillion dollars.
To check that value, I looked at the EMDAT Disaster Database. It contains no less than 11,654 detailed records of flood, wildfire, drought, storm, and extreme temperature disasters since 1950. The smallest of these had damages of $4.6 million dollars ($0.0000046 trillion). So it’s catching even very small disasters.
In 2020 dollars, the EMDAT database says that the total cost of those disasters since 1950 is about $10 trillion dollars.
So let us make the obviously incorrect and untenable assumption that 100% of those disaster costs are ascribable to the evil influence of CO2. It’s obviously not true by an order of magnitude or more, but let’s assume that each and every disaster is all 100% from CO2 for the purposes of discussion.
And given even that incorrect and wildly exaggerated assumption, the obvious question is … where is the other $87 trillion dollars of purported CO2 damages from weather-related disasters since 1950?
And it gets much worse if we don’t assume that 100% of the responsibility is due to CO2. Suppose we say (still an exaggeration) that 10% of the responsibility comes from CO2. That would mean that we are missing, not $87 trillion in disasters, but $960 trillion in disasters …
(Let me say that this kind of error, of just picking a random goal like “Net-Zero 2050” or just calculating a value for something like the “Social Cost of Carbon” and not testing the result for reasonableness against real-world data, is far too common in the world of climate “science”. I discuss this issue about “Net-Zero 2050” in my post “Bright Green Impossibilities“.)
And to repeat … where are the missing $87 trillion dollars in damages purportedly caused by so-called “climate disasters”?
My best to all,
w.
AS ALWAYS: I ask that when you comment you quote the exact words you are discussing. I can defend my own words. I cannot defend your interpretation of my words. Thanks.
I would suggest that a fair amount can be figured in damage to the economy. If you calculate all the failed companies that were paid for or bailed out by tax dollars, the increased cost of anything with an engine to cover emissions standards, the inefficiencies of refineries because you can’t build new ones due to environmental policy, etc. etc, you may find the total cost to the economy and drain on wealth will eat up a chunk of that missing $87 trillion.
The disaster is there alright – between all of them’s ears

I thought the damages included future damages, and damages included stuff like economically valuing impacts to humans and the environment.
The estimate of SCC is based on estimate upon estimate.
Using Dhaka as an example.
Say – Dhaka has 15m people of which 5m are impacted by flooding.
In 2100 it is estimated that the population of Dhaka to be 45m and their economic wealth doubles, and the area of the city subject to extra flooding doubles.
It would mean the level of impacts or forever suffering grows by a factor of 12. ( it is automatically assumed the extra rich people will move to the flood zones)
It is my understanding that SCC includes all these future exaggerated damages/impacts/sufferings.
Nice analysis, WE. I just looked up the SCC estimates for US. Under Trump, a maximum of $7. Under Biden, a minimum of $51. Now that’s real Bidenflation.
What about the Social Benefit of Carbon?
Consider, direct impact on, Life expectancy, infant mortality, health in general, education, and womens rights, for energy exporting countries such as Norway and indirect impacts on everyone else.
And one must also offset the costs of climate disasters that did not happen thanks to CO2.
The utter absurdity of this accounting is hurting my brain.
So basically, they are claiming that everything bad that has happened since 1950 was caused by CO2.
Everything about the claims has its own inflation – it’s continually worse than we thought
Willis:
You’re forgetting the valuation for Greta’s stolen childhood, which I guess accounts for most of that missing $87 trillion. On the other hand, some people think Greta’s childhood is the disaster.
There is a specific definition of the “Social Cost of Carbon” (SCC). It does not refer to past damages as you have stated:
“I read today that the EU is using an estimate of US$68 per tonne of CO2 emissions for the purported cost of the damages done by CO2. This is known by a Newspeak term as the “Social Cost Of Carbon”.”
The SCC refers to future NET damages (costs less benefits) resulting from each additional ton of CO2 emitted. The future damages/bebefits are discounted to net present value using a suitable discount rate.
Of course there is huge uncerainty in the calculations such as the discount rate used, equilibrium climate sensitivity, population growth/decline, etc. The uncertainty is so great that the calculated SCC has little value.
With apologies to Will Rogers:
Admiral Nimitz made a similar observation in response to Japanese claims of sinking multiple US carriers:
Thanks Willis. I always enjoy your lateral thinking take on “factchecking”. As an engineer involved for many years in electricity supply issues I have frequently had to deal with regulatory questions on the economist’s concept of “social cost of carbon (SCC)”. it seems to me that this number is far too elastic to inform any energy policy or planning.
I have seen proposed SCC estimates ranging from -$50 to +$400. Considering the well documented benefits of a mildly warmer environment and promotion of floral growth, I think it plausible that SCC has a net negative value. In other words by the same logic behind carbon pricing or taxation, we should receive carbon credits for burning fossil fuels 🙂
The reality is that, based on the paleoclimate record and the work done with models, the climate change we have been experiencing today is caused by the sun and the oceans over which mankind has no control. Despite the hype, there is no real evidence that CO2 has any effect on climate and there is plenty of scientific rationale to support the conclusion that the climate sensitivity of CO2 is zero. So CO2 is not responsible for any environmental disasters. On the other hand CO2 has enabled life as we know it on this planet. That has got to be worth something,
Not to mention the social benefits of emitting CO2…
Chicken Little says that the Sky is Falling and that it will cost us $97 Trillion dollars to fix it up in the Virtual World.
All weather related disasters have plummeted since the early 20th century- https://ourworldindata.org/natural-disasters
Willis, I’ll bet that the fruitcakes pushing unlimited disasters and inflated social cost of carbon never saw you coming! Prozac futures are going through the roof!
Only 4 days to go before BBC One screens The Trick and nothing from WUWT.
Phil Jones will be declared a hero after being hounded by climate change deniers for 12 years.
FFS wake up!
Its similar to the fossil fuel subsidy calculation.
In the subsidy studies, the largest “subsidies” are the difference between actual carbon taxes and whatever the study team thought they SHOULD have been, and depreciation of assets.
The largest part of the “cost of carbon” is what they think those disasters SHOULD have cost.
“but $960 trillion in disasters …”
Should be mi$$ing (97-1) = $96 trillion in disasters.
Another way to put it is that we’re missing (96/97)*100 = 99.0% of the damage purportedly caused by CO2 since 1950.
We know where it’s gone, don’t we. It ran off with Trenberth’s missing heat.
It’s so nice, isn’t it, when a new insight explains data that’s been sitting neglected and lonely in the literature. You’re welcome, Ken.
Even though you probably can’t show the governments pays for much of those disaster costs, ten percent is not to much lower than most charities deliver.
The actually issue should be where does all that carbon tax their citizens pay go?
Seems kind of high prices for indulgences for those exhaling and using energy. Those carbon taxes are likely part of a pyramid scheme.
Thanks WE for all your work.
“And given even that incorrect and wildly exaggerated assumption, the obvious question is … where is the other $87 trillion dollars of purported CO2 damages from weather-related disasters since 1950?”
A large error could be in thinking that the only damage from CO2 is disasters. You really need to find out what their definition is.
Willis has some form on this. See https://rosebyanyothernameblog.wordpress.com/2018/12/15/the-social-benefit-of-carbon/ where he works out:
“As Figure 6 shows, the benefit that we get from emitting that additional tonne of carbon dioxide into the atmosphere is an increase in goods and services of $4,380 … which dwarfs the assumed social cost of carbon of $40. When we do an actual cost/benefit analysis, the result is almost all benefit.”
(Note- seems the pictures there don’t show, may need to refer to https://wattsupwiththat.com/2018/12/15/the-social-benefit-of-carbon/ to get the pictures.)
Thus even with the !diots claiming that our CO2 emissions have cost us $97T since 1950, we’ve gained around 10 times that from the use of that energy.
From Willis’ calculations above, though, looks like the actual SCC is an order of magnitude less than the EU estimate, so the cost/benefit ratio for using those fossil fuels gets even better. Apart from that, of course, there’s the slight problem that without that cheap energy we couldn’t feed the population we have.
$97 TRILLION dollars since 1950!! What’s the value of the estimated 10% – 15% of increases in C3 crop yields (rice, wheat, potatoes…) over the past half century or so?
