What this tells me is that there cannot be very high positive temperature feedback within the climate system if the “normal” or pre-industrial temperature record is totally flat.

Observational and theoretical evidence that cloud feedback decreases global warming
Guest Post by Willis Eschenbach Well, I decided to take a shot at publishing my views on the cloud feedback response to increases in surface warming. I wrote it up…
The Climate Feedback Debate
Unless somebody has a better explanation, it seems likely that the IPCC needed to keep the 3.0°C ECS for political reasons and simply altered the various feedback parameters to suit.
Outside the Black Box: Back to Basics
This cannot be a coincidence and clearly shows that the CERES data do not support the outcomes of GCM calculations:
Earth Can Regulate its Own Temperature Over Millennia, New Study Finds
Scientists have confirmed that a “stabilizing feedback” on 100,000-year timescales keeps global temperatures in check
Why It Matters That Climatologists Forgot the Sun Was Shining
Yet our result shows that official climatology’s conclusions, based as they are on the outputs of general-circulation models, are mere guesswork. They do not in any degree warrant or justify…
Refutation of the Forgotten-Sunshine Theory
The theory that feedback law rules out high ECS values is like the theory that there’s no greenhouse effect: although its conclusion is attractive, the theory itself is clearly wrong.
How Climatologists Forgot the Sun Was Shining: Your Questions Answered
Their error was so large that, after correction, the near-certainty of future global warming large enough to be catastrophic vanishes, and the tawdry notion of “climate emergency” with it.
Are Climate Feedbacks Strongly Non-Linear?
Is it possible that the Earth’s system is strongly buffered with strong positive ice and dust feedbacks prevailing at colder temperatures, and strong negative convection/evaporation feedbacks prevailing in warmer times?
The Greenhouse Effect In A Water World
There are multiple lines of evidence, however, that challenge the strong water vapour feedback to a small initial CO2 forcing. These strong positive feedbacks are central to the IPCC narrative.
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…
Cloud Feedback, if there is any, is Negative
Guest post by Mike Jonas, Maybe, after all the attention being paid to the Wuhan virus, it’s time to do a bit of climate science again. I have submitted a…
Models, Feedbacks, And Propagation Of Error
Guest post by Kevin Kilty Introduction I had contemplated a contribution involving feedback diagrams, systems of equations, differential equations, and propagation of error ever since Nick Stoke’s original contribution about…
Answer to a whigmaleerie about temperature feedback
By Christopher Monckton of Brenchley Some days ago, a prolix, inspissate whigmaleerie was posted here – a gaseous halation, an unwholesome effluvium, an interminable and obscurantist expatiation purporting to cast…
Climatology’s startling error of physics: answers to comments
Answers to comments from the original essay on WUWT, here. By Christopher Monckton of Brenchley I make no apology for returning to the topic of the striking error of physics…
Looping the loop: how the IPCC's feedback aerobatics failed
Guest essay By Christopher Monckton of Brenchley This series discusses climatology’s recently-discovered grave error in having failed to take due account of the large feedback response to emission temperature. Correct…
Another climate feedback found: ‘cooling effect of natural atmospheric particles is greater during warmer years’
From the University of Leeds and the “settled science” department, comes this new idea that combines measurements with a model. Understanding the climate impact of natural atmospheric particles An…
Evaporation Redux
Guest Post by Willis Eschenbach I got to thinking again about the question of evaporation and rainfall. I wrote about it here a few years ago. Short version—when the earth’s…
Feedback on Feedbacks
Guest essay by Rud Istvan In recent weeks, there have been a number of WUWT guest posts on climate sensitivity related matters. Sensitivity is determined by feedbacks to increased CO2.…
How Climate Feedback is Fubar
Guest essay by George White Feedback is the most misunderstood topic in climate science and this misunderstanding extends to both sides of the debate. This is disturbing because the theoretical…
Cloud Feedback
Guest Post by Willis Eschenbach In the comments to Christopher Monckton’s latest post, Nick Stokes drew attention to Soden and Held’s analysis of feedback in the climate models. I reproduce their Table…
Soil feedbacks are a big uncertainty in climate change
From the YALE SCHOOL OF FORESTRY & ENVIRONMENTAL STUDIES Managing uncertainty: How soil carbon feedbacks could affect climate change There is more than twice as much carbon in the planet’s…
Claim: Future global warming could be even warmer
From the UNIVERSITY OF COPENHAGEN – NIELS BOHR INSTITUTE and the “worse than we thought” department comes this claim by one researcher looking at the past climate events, specifically the PETM,…
Problems With Analyzing Governed Systems
Guest Post by Willis Eschenbach I’ve been ruminating on the continuing misunderstanding of my position that a governor is fundamentally different from simple feedback. People say things like “A governor…
