By Andy May Christian Freuer has translated this post to German here. In part one we discussed various estimates of climate sensitivity (ECS, TCR, and observation-based values) and what they mean, especially those reported in the latest IPCC report, AR6. In part 2 we discussed the uncertainty in estimating cloud feedback to surface warming, andContinue reading “The Mysterious AR6 ECS, Part 4, converting observations to ECS”

The Mysterious AR6 ECS, Part 2, the Impact of Clouds
By Andy May Christian Freuer has translated this post to German here. The yearly net impact of clouds on outgoing and incoming radiation varies over one W/m2 from year-to-year, according to CERES satellite data.[1] AR6 tells us that cloud feedbacks, to GHG surface warming, are the largest source of uncertainty in their assessment of theContinue reading “The Mysterious AR6 ECS, Part 2, the Impact of Clouds”

The Mysterious AR6 ECS, Part 1
By Andy May Christian Freuer has translated this post to German here. The climate sensitivity to CO2 and other greenhouse gases (GHGs) is arguably the most important number in the climate change debate. AR6[1] claims the sensitivity, which they call “ECS” or the equilibrium climate sensitivity, is three degrees per doubling of CO2, or 3°C/2xCO2Continue reading “The Mysterious AR6 ECS, Part 1”

The error of the mean: a dispute between Gavin Schmidt and Nicola Scafetta
By Andy May You can read this post in German here, courtesy of Christian Freuer. Here we go again, writing on the proper use of statistics in climate science. Traditionally, the most serious errors in statistical analysis are made in the social sciences, with medical papers coming in a close second. Climate science is bitingContinue reading “The error of the mean: a dispute between Gavin Schmidt and Nicola Scafetta”

The Exxon Climate Papers
A group of Democrat attorneys general and environmental activists are accusing ExxonMobil of lying about climate change. Is it true?

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”
