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 [...]
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 [...]
Tony and Kirye Name: Tony Heller Country: USA “Hello, this is Tony Heller from realclimatescience.com, setting the record straight on climate.” This is the standard opening sentence in the many Youtube-videos that Tony Heller has put online. Heller has become a well-known figure in the public climate debate, with his website, his [...]
Earlier this week a video about climate science appeared on social media by Sabine Hossenfelder1. Dr. Hossenfelder, who did her Ph.D. in Theoretical Physics at Frankfurt, Germany, should be congratulated for popularizing science on the internet2. In this particular video, she discusses the greenhouse effect: I Misunderstood the Greenhouse Effect. Here's How It Works. [...]
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 [...]
