The featured image is a photograph of the Big Bend area in Texas in October 2015 when the drought index was moderately moist. The photo was taken by the author. Stories of some sort of current catastrophic drought in the western U.S. are greatly exaggerated (apologies to Mark Twain). While the western U.S. [...]

The following is based on remarks delivered by Steven Koonin and Mark Mills at an MIT Free Speech Alliance debate, which can be viewed here. Reposted from RealClearWorld.com The climate change debate continues to rage. Though the science remains “unsettled,” what does seem settled is that President Trump will withdraw, again, from the [...]

To read this post in German see here, translation by Christian Freuer. The IPCC and the climate “consensus” believe that essentially all warming since 1750 is due to man’s emissions of CO2 and other greenhouse gases as shown in figure 1 here or in (IPCC, 2021, p. 961). This has led to a 45-year search for the value of [...]

This post is a comment on Cobb, 2024, the paper is entitled “The politics of climate denialism and the secondary denialism of economics.” The paper defines climate denialism, discusses the reasons it exists, and the effect of widespread “denialism” on society. The paper was written in response to a paper I wrote with my [...]

I last wrote about Climate Change and Civilization for the past 4,000 Years in 2016. Since then, a lot has changed, and I’ve learned a lot more about the subject. First, we learned that various air and sea temperature proxies, such as ice core δ18O or tree rings, are all different. For a discussion of some temperature [...]

“Consensus” scientists do not believe that solar variability, internal climate variability (in this model simplified to the ~67-year stadium wave), or volcanism influence net global warming or climate change since 1750, yet considerable evidence exists that these factors have an impact. I’ve previously built a model of the HadCRUT5 global average temperature (see here) from seven [...]
