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 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 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 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 [...]

The Climate Alarmist’s Greatest Fear

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 [...]

2022 Seventh Warmest Year: Warming Slows Down

Guest Post by Javier Vinós reposted from Andy May's Climate Blog No minimally informed person denies that climate changes. The climate has always changed. Since 1860 the predominant climate change has been warming, which is fortunate because if we had a winter like those of 1800-1850, we would be in for a shock. [...]

Meridional Transport, the most fundamental climate variable

By Andy May “The atmospheric heat transport on Earth from the Equator to the poles is largely carried out by the mid-latitude storms. However, there is no satisfactory theory to describe this fundamental feature of the Earth’s climate.” (Barry, Craig, & Thuburn, 2002) This is the transcript of the talk I gave in [...]

Are fossil-fuel CO2 emissions good or bad?

By Andy May This is the transcript, with minor edits to get it into blog post format, of my keynote speech to the AAPG Division of Professional Affairs, at the second International Meeting for Applied Geoscience and Energy Convention in the George R. Brown Convention Center in Houston on August 30, 2022. Andy May Petrophysicist [...]
