Annotated Bibliography for Climate: The Movie

By |2024-04-12T12:11:27+02:008 April 2024|News, USA|Comments Off on Annotated Bibliography for Climate: The Movie

Reposted from Andy May Petrophysicist Many viewers of Climate: The Movie have asked for more information on the topics discussed. In response, I selected the following 70 key statements from the movie and provide references and context for the statements here. Sometimes the statements are slightly paraphrased from what was said for brevity. The [...]

Solar Activity: Cycle 25 Surpasses Cycle 24

By |2023-07-06T14:24:05+02:006 July 2023|News, USA|Comments Off on Solar Activity: Cycle 25 Surpasses Cycle 24

By Javier Vinós reposted from Andy May Petrophysicist 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 [...]

A Twitter Debate on Clintel’s IPCC AR6 Critique

By |2023-07-05T12:01:36+02:005 July 2023|CLINTEL, IPCC, News, USA|Comments Off on 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 [...]

Is AR6 the worst and most biased IPCC Report?

By |2023-05-19T10:25:18+02:0019 May 2023|CLINTEL, News, USA|Comments Off on Is AR6 the worst and most biased IPCC Report?

By Andy May This is the text of my presentation on Tom Nelson’s podcast which can be viewed here. The question and answers start at about 18:15 into the interview. The first IPCC Physical Science Basis report is called “FAR” and was first published in 1990. An updated 1992 version of the report contains this [...]

The error of the mean: a dispute between Gavin Schmidt and Nicola Scafetta

By |2023-04-15T11:25:02+02:0015 April 2023|News, USA|Comments Off on The error of the mean: a dispute between Gavin Schmidt and Nicola Scafetta

By Andy May You can read this post in German here, courtesy of Christian Freuer. Here we go again, writing on the proper use of statistics in climate science. Traditionally, the most serious errors in statistical analysis are made in the social sciences, with medical papers coming in a close second. Climate science is biting [...]

Atmospheric water vapor (TPW) and climate change

By |2023-03-22T14:13:39+01:0022 March 2023|News, USA|Comments Off on Atmospheric water vapor (TPW) and climate change

By Andy May In the latest IPCC major report, AR6, they report: “a best estimate of equilibrium climate sensitivity of 3°C, with a very likely range of 2°C to 5°C”.[1] They also report that CO2 concentration might control climate change.[2] This estimate includes the laboratory estimate that CO2 alone, if doubled in the atmosphere, would increase the average [...]

The Holocene Temperature Conundrum

By |2023-02-26T17:01:21+01:0026 February 2023|News, USA|Comments Off on The Holocene Temperature Conundrum

By Andy May As my regular readers know, I’ve been writing about the Holocene, especially Holocene climate, for over ten years. My colleagues, Javier Vinós and Renee Hannon, have also written extensively on this topic. This fills a void left by the IPCC, which ignores the Holocene, a fact made very clear in my [...]

Holocene CO2 and the earlier IPCC Reports

By |2023-02-24T15:27:47+01:0024 February 2023|News, USA|Comments Off on Holocene CO2 and the earlier IPCC Reports

By Andy May As I noted in my earlier post, “The IPCC AR6 Report Erases the Holocene,” the IPCC does not like to discuss the correlation between CO2 and temperature during the Holocene. It destroys their hypothesis that greenhouse gases and volcanos control Earth’s climate. Below is Javier’s plot of reconstructed Holocene temperatures, CO2 concentrations, methane [...]

The IPCC AR6 Report Erases the Holocene

By |2023-02-06T11:18:15+01:006 February 2023|News, USA|Comments Off on The IPCC AR6 Report Erases the Holocene

By Andy May Reposted from his website You won’t find much in the IPCC AR6 report on the atmospheric CO2 concentration evolution during the Holocene. They talk a lot about how CO2 concentration compares to global temperature during the years since 1850 and over the past 800,000 years, but very little about the changes since 12,000 years ago. On [...]
