Well, I’ve been reading the fine print of the IPCC AR6 WG1 Report. The authors are to be congratulated for preparing a document that is vastly more intellectually sophisticated than…

CMIP6 ECS
It is apparent that those who believe in anthropogenic global warming do not understand the intractable fundamental problem with their climate model approach. They are digging themselves a deeper hole.…
A WUWT “Comment Rebuke”
To summarize without any math, the GHE exists. It experimentally must, and easily provably does. The GHE issues are how much when (ECS), not if. Any ‘skeptical’ arguments to the…
Climate ECS Closure
There are two notions of ECS. The first is without feedbacks (mainly water vapor and clouds). It estimates a simple non-condensing gas CO2 doubling. AR4 implicitly had that at a…
An Electronic Analog to Climate Feedback
Here we simulate a “test rig” for illustrating the difference between Christopher Monckton’s approach to projecting equilibrium climate sensitivity (“ECS”) and what he says climatology’s approach is. (ECS is the…
Why Models Can’t Predict Temperature: A History Of Failure
The bottom line is that climatology is simply wrong about the magnitude of future global warming. No government should pay the slightest attention to anything it says.
Compensation between cloud feedback + ECS and aerosol-cloud forcing in CMIP6 models
The new open-access paper – the senior author of which, Gabriel Vecchi, is a well known professor of geosciences at Princeton University – provides further evidence that high ECS CMIP6…
How much global warming should IPCC’s next report predict?
Mainstream climate scientists have been busy in the last two years, publishing updated climatological data in time for IPCC’s forthcoming Sixth Assessment Report. The availability of those recent mainstream data…
Disconnect in the relationship between GMST and ECS
Abstract. An analysis is presented of he disconnection between the CMIP5 and CMIP6 Historical and Future periods when considering the relationship of the individual model GMST changes and the climate…
Crisis looms in alarmist climate science
Climate science is dominated by alarmists addicted to the idea that increasing carbon dioxide will cause dangerous global warming. How much warming is thus the central scientific question.
Emergent constraints on TCR and ECS from historical warming in CMIP5 and CMIP6 models
I note that Earth Systems Dynamics published the paper despite one of the two peer reviewers recommending against acceptance without further major revisions. But neither of the reviewers appear to…
Two more degrees by 2100!
From Dr Judith Curry’s Climate Etc. Posted on December 27, 2019 by curryja | by Vaughan Pratt An alternative perspective on 3 degrees C? This post was originally intended as…
What’s the worst case? Climate sensitivity
Posted on April 1, 2019 by curryja | Reposted from Climate Etc. by Judith Curry Are values of equilibrium climate sensitivity > 4.5 C plausible? For background, see these previous…
Climate Insensitivity
Guest Post by Willis Eschenbach I’ve been wanting to [take] another look at the relationship between net top-of-atmosphere (TOA) radiation changes on the one hand and changes in temperature on…
The Fatal Lure of Assumed Linearity
Guest Post by Willis Eschenbach [note new Update at the end, and new Figs. 4-6] In climate science, linearity is the order of the day. The global climate models are…
