By Andy May It is difficult to compare 1840 to 2015, so much of what we have today didn’t exist then. But, they had to move people and goods from place to place as we do now. They had farms then as we do now. They used wagons pulled by horses, mules or oxen. WeContinue reading “The Value of Petroleum Fuels”

Holocene Thermal Optimum
By Andy May The Holocene Thermal Maximum, also called the Holocene Thermal Optimum or the Holocene Climatic Optimum, occurred at different times in different parts of the world but generally between 10,000 BP and 4,000 BP. I use BP to indicate years before 2000. The world ocean was probably 0.7°C warmer than today 8,000 BP.Continue reading “Holocene Thermal Optimum”

Dr. Harold Lewis, why he resigned from the American Physical Society (APS)
Dr. Harold Lewis was a towering figure in physics. He resigned from the APS and detailed his reasons in an important open letter. In his view government research grants corrupted the APS. The environmental community has tried to demonize privately funded research as “corrupt” so that “pristine” government funding has a monopoly on research. InContinue reading “Dr. Harold Lewis, why he resigned from the American Physical Society (APS)”

Dr. Benny Peiser’s notes on the UK Met Conference on Avoiding Dangerous Climate Change
Dr. Peiser’s notes on the 2005 UK conference are worth a read. He notes that Professor Yuri Israel, the chief climatologist at the Russian Academy of Science estimated that attempts to stabilize the world’s climate may cost 18 trillion US dollars! He encouraged adaptation and little mitigation. He was rudely and disrespectfully admonished by theContinue reading “Dr. Benny Peiser’s notes on the UK Met Conference on Avoiding Dangerous Climate Change”

A Short Summary of Soon, Connolly and Connolly, 2015; “Re-evaluating the role of solar variability on Northern Hemisphere temperature trends since the 19th Century”
By Andy May Soon, Connolly and Connolly (2015) is an excellent paper (pay walled, for the authors preprint, go here) that casts some doubt about two critical IPCC AR5 statements, quoted below: The IPCC, 2013 report page 16: “Equilibrium climate sensitivity is likely in the range 1.5°C to 4.5°C (high confidence), extremely unlikely less thanContinue reading “A Short Summary of Soon, Connolly and Connolly, 2015; “Re-evaluating the role of solar variability on Northern Hemisphere temperature trends since the 19th Century””

Notes on the APS Workshop on Climate Change
By Andy May In January, 2014 the American Physical Society (APS) held a one day workshop on climate change and invited six climatologists to participate. A full transcript of the workshop can be found here. The six speakers are all very eminent climate scientists. The discussion was limited to the physical basis of climate changeContinue reading “Notes on the APS Workshop on Climate Change”

On the new EPA Carbon Dioxide emission rule for power plants on Regulations.gov
This is a comment I put on regulations.gov about the proposed new rule. The key assumption in this rule is that man-made Carbon Dioxide is harmful to the environment by altering our climate. I do not think this is proven. The key elements of the debate on man-made catastrophic climate change are actually pretty simple.Continue reading “On the new EPA Carbon Dioxide emission rule for power plants on Regulations.gov”
