Peer Reviewed Climate Skepticism

Published July 8, 2024

A fine skeptical journal article waded through green pal review. Wonder of wonders!

The journal is the American Journal of Economics and Sociology. The article title is perfectly clear: “Carbon dioxide and a warming climate are not problems”. See

But it is an “Early View Online Version of Record before inclusion in an issue” so get it before it gets too hot for the Journal. I understand it is very popular so the green screams are deafening.

Alas it is paywalled but the lengthy free Abstract is as clear as the title. Here is the conclusion:

“Observations show no increase in damage or any danger to humanity today due to extreme weather or global warming (Crok & May,  2023, pp. 140–161; Scafetta,  2024). Climate change mitigation, according to AR6, means curtailing the use of fossil fuels, even though fossil fuels are still abundant and inexpensive. Since the current climate is arguably better than the pre-industrial climate and we have observed no increase in extreme weather or climate mortality, we conclude that we can plan to adapt to any future changes. Until a danger is identified, there is no need to eliminate fossil fuel use.”

The authors are Andy May and Marcel Crok and as the first parenthetical reference above indicates they are building on prior work. Their 53 References are not paywalled and quite interesting.

Both authors list as from CLINTEL making this a worthy CLINTEL effort. In fact Croc is a co-founder of CLINTEL. This work certainly supports CLINTEL’s World Climate Declaration that “There is no climate emergency”. See which offers an opportunity to sign, joining the almost 2,000 signatories and growing (including me).

The article is a clear discussion of the basic issues including some of the uncertainties. The overall position is moderate compared to some forms of skepticism (including mine). This makes it a good non-technical entering wedge for the climate debate.

Here is their overall conclusion:

“Clearly, there are two sides to climate change. It will be a problem in the future for some people in some places and a benefit for others in other places. Climate changes, it always has and always will. Is it changing more now than in the past? Or are we comparing current climate change to some fantasy world where climate never changes?

Warmer temperatures and more CO2 will mean more food at a lower price for nearly everyone, but in some areas, drought will increase and in others additional precipitation will cause flooding. However, with modern technology and cheap energy, we can build aqueducts to bring water to dry areas and build dikes and seawalls to protect areas prone to flooding. Sea level rise is currently a very modest two millimeters per year, it may be accelerating at about .02 mm/year, but the rise in the next century will be less than a foot, about a third of the normal average ocean daily tide.

Currently fossil fuels supply about 80% of our energy, reducing this to zero rapidly will devastate the world economy and cause widespread suffering, especially for the poor. Should we do nothing? If so, the President’s Council of Economic Advisors and the U.S. Office of Management and Budget projects that three degrees of global warming will cause a decline of <1% in U.S. GDP. Modern global warming, since 1950, has reduced GDP by <.5%, a trivial amount given that the economy has grown 800% in that time. Using IPCC scenarios, Lomborg estimates that economic growth will decline from 450% to 434% over the 21st century. Will anyone notice?

The infrastructure to replace fossil fuels does not exist and likely cannot be built in a short time. Current realistic estimates of future energy use suggest that fossil fuels will still supply half our energy in 2050 and beyond. Yet, no credible evidence exists that this is a problem or will become a problem. Recent research into climate change has suggested that nature plays some role, and certainly greenhouse gas emissions may play some role as well. What we do not know is how much of climate change is human-caused and how much is natural. No drastic changes to our economy are justified until we can figure this out.”

Please spread the word about this fine article. The more attention it gets the harder it will be to kill.
