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 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 [...]
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 [...]
By Andy May Tom Nelson interviewed Dr. Javier Vinós on January 31, 2023, the interview can be seen here. Or click on the image below. Part of the interview was a prepared presentation. The text and some of the illustrations from Javier’s presentation are given below. The recorded interview has more illustrations [...]
By Andy May Is it just me, or are the climate alarmists more unhinged than usual lately? Al Gore screaming about boiling oceans and rain bombs is just part of it. As Eric Worral has reported, the BBC blamed global warming for the lack of snow, just after they blamed global warming for colder winters. And, who [...]
"If it [a scientific hypothesis] disagrees with experiment, it’s WRONG." – Nobel Prize winner Richard Feynman The popular but mistaken belief that weather extremes are worsening because of climate change has been bolstered in recent years by ever increasing hype in nearly all mainstream media coverage of extreme events, despite a [...]
On Tuesday, CFACT lost another friend, Dr. Jay Lehr. What a man he was! Dr. Jay Lehr CFACT’s friends and readers have been treated to a brilliant weekly science update from Jay. He has served as a Senior Policy Advisor to CFACT since 2020. The day before we lost him, we published a [...]
"If it [a scientific hypothesis] disagrees with experiment, it’s WRONG." – Nobel Prize winner Richard Feynman According to the climate change narrative, modern global warming is largely the result of human emissions of CO2 into the atmosphere. But a recent lecture questioned that assertion with an important observation suggesting that ocean surface temperatures, not [...]
