More on the statistical dispute between Scafetta and Schmidt

By Andy May The argument about the proper way to estimate error in the European Centre for Medium-Range Weather Forecast (ECMWF) ERA5 weather reanalysis dataset between Nicola Scafetta and Gavin Schmidt has finally been published by Geophysical Research Letters. Schmidt, Jones, and Kennedy’s comment is here (Schmidt, Jones, & Kennedy, 2023), and Scafetta’s response isContinue reading “More on the statistical dispute between Scafetta and Schmidt”

Wall Street Journal Article on Exxon’s “beliefs”

By Andy May Open letter to the authors of the Wall Street Journal article: “Inside Exxon’s Strategy to Downplay Climate Change,” by Christopher M. Matthews and Collin Eaton. Dear Mr. Matthews and Mr. Eaton, I was quite surprised to see your article in the news section of the September 14, 2023 issue of the WallContinue reading “Wall Street Journal Article on Exxon’s “beliefs””

The Buzz about The Frozen Climate Views of the IPCC

By Andy May Our new book, The Frozen Climate Views of the IPCC: An Analysis of AR6, is creating a lot of attention and excitement around the world. It is the first authoritative critique of the new IPCC (Intergovernmental Panel on Climate Change) climate change report, “AR6.” AR6 ignores all climate change research that goesContinue reading “The Buzz about The Frozen Climate Views of the IPCC”

How the 2015 Major El Niño Was Predicted Years in Advance using a Lunar Cycle

By Javier Vinós The Earth’s oceans contain a vast mass of cold water beneath a thin layer of warm water, and the limited amount of mixing between them plays a crucial role in our existence. Tides, primarily influenced by changes in the moon’s orbit, are the main force behind this mixing, which has the potentialContinue reading “How the 2015 Major El Niño Was Predicted Years in Advance using a Lunar Cycle”

Understanding the role of the sun in climate change

By Nicola Scafetta Although the sun provides nearly all the energy needed to warm the planet, its contribution to climate change remains widely questioned. Many empirically based studies claim that it has a significant effect on climate, while others (often based on computer global climate simulations) claim that it has a small effect.

My CO2 Presentation to Clintel

The presentation was given to the public at the beautiful Hotel Villa Flora in Hillegom, Netherlands, on June 20, 2023. It was organized by Marcel Crok, director of Clintel. You can watch the whole presentation on “Are fossil-fuel CO2 emissions good or bad?” here. I discussed the 2016 debate between Professor David Karoly, Professor ofContinue reading “My CO2 Presentation to Clintel”

Solar Activity: Cycle 25 Surpasses Cycle 24

By Javier Vinós Over the past two decades, solar activity has been characterized by an extended solar minimum spanning two solar cycles, known as the Clilverd Minimum. This phenomenon is currently affecting the climate, but before we can understand its impact, we must address the significant discrepancy between the solar effects observed in paleoclimate proxyContinue reading “Solar Activity: Cycle 25 Surpasses Cycle 24”

A Twitter Debate on Clintel’s IPCC AR6 Critique

By Andy May In May 2023, Clintel published a book (see figure 1) criticizing AR6 (IPCC, 2021), a publication that was supposed to summarize climate science research to date. We found that AR6 was biased in its reporting of recent developments in climate science, and they ignored published research contrary to their narrative that humansContinue reading “A Twitter Debate on Clintel’s IPCC AR6 Critique”

A Critique of AR6

By Andy May Read in German here, courtesy of Christian Freuer. After more than two years of hard work, Marcel Crok, I, and 11 other scientists have finally published our critique of the Intergovernmental Panel on Climate Change (IPCC) sixth report (AR6). The entire book has been extensively peer reviewed and a low-resolution pdf ofContinue reading “A Critique of AR6”

The Holocene CO2 Dilemma

Guest Post By Renee Hannon This post evaluates the relationship of global CO2 with regional temperature trends during the Holocene interglacial period. Ice core records show that CO2 is strongly coupled with local Antarctic temperature and slightly lags temperature over the past 800,000 years (Luthi, 2008). Whereas the emphasis has been on CO2 and temperatureContinue reading “The Holocene CO2 Dilemma”
