The IPCC AR5 report was published in 2013 and the CMIP5 climate models they used, have been shown to predict faster warming than observed in the tropical troposphere at a statistically significant level by Ross McKitrick and John Christy.[1] This problem is acknowledged and discussed in the latest AR6 report, published in 2021, but brushed aside as unimportant. In [...]
In my last post, I explained how the IPCC attempts to use climate models to show humans have caused the recent global warming. Models are useful for testing scientific ideas, but they are not proof an idea is correct unless they successfully and accurately predict future events. See the story of Arthur Eddington’s test [...]
The featured cartoon is by Josh, who graciously gave me permission to use it, his website is here. This cartoon is in Josh’s 2022 calendar, I think he still has a few to sell.

As Holman Jenkins explains in yesterday’s Wall Street Journal (Jenkins, [...]
by Judith Curry “The current thinking and approaches guiding this conceptualization and description have been shown to lack scientific rigour, the consequence being that climate change risk and uncertainties are poorly presented. The climate change field needs to strengthen its risk science basis, to improve the current situation.” – Norwegian risk scientist Terje Aven [...]
Guest essay by Larry Hamlin The Climate Intelligence Foundation (CLINTEL) has cataloged significant errors in the UN IPCC AR6 Summary for Policy Makers (SPM) and distributed this error listing and analysis to the IPCC Chair and other world leaders to inform them of these errors. The identified errors result in the SPM failing to meet standards of [...]

This means the court cannot intervene in the case. However, the lower appeals court did say, according to the Texas Civil Justice League: “The court of [...]
You are built almost entirely out of carbon dioxide and water. So is all the food you eat. Likewise for all the energy you use moving about and staying alive. Carbon dioxide and water! In short the carbon dioxide in the air is the global food supply. This is why all life on Earth [...]
By now most people will have heard about the podcast of Joe Rogan. His concept is simple: invite an interesting guest, don't prepare the interview too much and talk for a couple of hours. Rogan was accused of spreading 'misinformation' about Covid during interviews with Robert Malone and Peter McCullough. Rogan has become [...]
By Andy May This is the transcript of a talk I gave to the ASME (The American Society of Mechanical Engineers) South Texas Section January 20, 2022 Federal money allows unelected bureaucrats to control scientific research. They dictate the projects, and often the outcomes. They use selective leaks to the press to embarrass anyone [...]
