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””

New Book: A Disgrace to the Profession, by Mark Steyn

Mark Steyn has written a wonderful new book on Dr. Michael Mann’s hockey stick and the controversy surrounding it. It is difficult to overstate the significance or impact of Mann’s Hockey Stick (Mann, Bradley, Hughes (23 April 1998), “Global-scale temperature patterns and climate forcing over the past six centuries” (PDF), Nature 392 (6678): 779–787, Figure 5, the paper is oftenContinue reading “New Book: A Disgrace to the Profession, by Mark Steyn”

Notes on the APS Workshop on Climate Change

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 change and atmospheric physicsContinue 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”
