Willie Soon, Ronan and his father Michael Connolly released a new interesting video about the snow cover debate. Clintel covers this debate in chapter 4 of our report The Frozen Climate Views of the IPCC. The three scientists published a paper in 2019 comparing snow cover in climate models with observations. In [...]
Professor Dr. Hoesung Lee, Chair of the IPCC, c/o World Meteorological Organization 7bis Avenue de la Paix C.P. 2300 CH -1211 Geneva 2, Switzerland. The Hague, May 25, 2023 Dear Dr. Hoesung Lee, With the recently published Synthesis Report, the IPCC finished its sixth assessment cycle, consisting of seven reports in [...]
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 [...]
© Clintel Foundation / Tuesday May 9, 2023 Amsterdam, 9 May 2023 * IPCC hides good news about disaster losses and climate-related deaths * IPCC wrongly claimed the estimate of climate sensitivity is above 2.5°C; it is more likely below 2°C * IPCC misleads policy makers [...]
An international team of scientists from the Clintel network has looked into parts of the Working Group 1 and Working Group 2 reports of the IPCC Sixth Assessment report. The report will be released on Wednesday 26 April. To stay informed about this and other Clintel projects, please subscribe to our newsletter. Clintel [...]
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 [...]
Senator John Kennedy tried to get an estimate of the cost of net zero in a recent hearing By Christopher Monckton of Brenchley The New Pause has lengthened to 8 years 9 months. The least-squares linear-regression trend on the UAH monthly satellite global-temperature dataset shows no global warming from July 2014 to March [...]
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 [...]
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 [...]
By Javier Vinós Most people don’t have a clear understanding of the greenhouse effect (GHE). It is not complicated to understand, but it is usually not well explained. It is often described as “heat-trapping,” but that is incorrect. Greenhouse gases (GHG) do not trap heat, even if more heat resides within the [...]
