Guest Post by Willis Eschenbach I got to thinking about the clouds again. They’re easily the least understood part of the climate. So let me start with what we do…

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…
Uncertain Clouds
Guest Post by Willis Eschenbach I read an interesting quote in the latest Climanifesto from the Intergovernmental Panel on Climate Change, their Sixth Assessment Report, known as “IPCC AR6” to…
Thunderstorm World: A Model to Explore Ideas from Willis Eschenbach
I’ve been thinking about some ideas that WUWT contributor Willis Eschenbach (WE) has proposed. In particular, WE has suggested that tropical cumulus clouds and thunderstorms provide a “thermostatic mechanism” that…
Clouds and Global Warming
By Andy May This post is inspired by an old post on the CERES cloud data by Willis Eschenbach that I’ve read and re-read a lot, “Estimating Cloud Feedback Using…
Clouds From Both Sides Now
Guest Post by Willis Eschenbach Clouds are said to be the largest uncertainty in climate models, and I can believe that. Their representation in the models is highly parameterized, each…
A 2021 Index to Willis’s Posts
Guest Post by Willis Eschenbach It’s February 3rd, 2021. I hadn’t updated my index since 2018, so I decided to do so. Not an easy task, but I beat it…
Podcast: The Calamity of Models (Guest: Willis Eschenbach)
Both climate and coronavirus models continue to fail. Why do we still look at them for deciding public policy? Our resident polymath Willis Eschenbach joins Anthony Watts to discuss the…
The Calamity of Models – Podcast with Willis Eschenbach
Computer models are sometimes useful, and often wrong. In the case of climate and Coronavirus predictions, “wrong” doesn’t even begin to describe it.
Clouds and El Nino
Guest Post by Willis Eschenbach After the turn of the century, I became interested in climate science. But unlike almost everyone else, I wasn’t surprised by how much the global…
A factual comment on Willlis Eschenbach’s and Christopher Monckton’s most recent posts, concerning clouds and ECS, respectively.
Guest opinion by Rud Istvan I have but little scientifically to contribute, since they have been mostly factually correct. But here I provide a little more scientific evidence, visual observational…
Clouds Down Under
Guest Post by Willis Eschenbach [See Update at the end] Sometimes climate research is just plain funny. I wrote before about Irish rain and investigated whether there is any effect…
Glimpsed Through The Clouds
Guest Post by Willis Eschenbach [See Update at the end.] [See Second Update at the end.] In a recent post, I discussed the new CERES Edition 4.0 dataset. See that post…
A New Index to Willis’s Posts
Guest Post by Willis Eschenbach Well, my old index to my posts was out of date, and I finally got tired of not being able to find things that I’ve…
CERES Edition 4 and the Cloud Radiative Effect
Guest Post by Willis Eschenbach One of the enduring questions in climate involves what is usually called “cloud feedback”. When the earth warms up a bit, the clouds change in…
Quote of the week: The clouds, the 1%, and the ‘holy grail’ of climate science
People send me stuff. Today my inbox got what some people might describe as an important clue to finding the “holy grail” of climate science. It’s a big step forward,…
Estimating Cloud Feedback Using CERES Data
.Guest Post by Willis Eschenbach As usual, Dr. Judith Curry’s Week In Review – Science Edition contains interesting studies. I took a look at one entitled “Cloud feedback mechanisms and…
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…
Willis and I walk the Planck
By Christopher Monckton of Brenchley I do apologize for not having replied sooner to my friend the irrepressible, irascible, highly improbable but always fascinating Willis Eschenbach, who on August 15…
Cooling and Warming, Clouds and Thunderstorms
Guest Post by Willis Eschenbach Following up on a suggestion made to me by one of my long-time scientific heroes, Dr. Fred Singer, I’ve been looking at the rainfall dataset…
Cloud Feedback
Guest essay by Stan Robertson In a recent post entitled “Changes in Total Solar Irradiance” (http://wattsupwiththat.com/2014/10/25/changes-in-total-solar-irradiance/ ), Willis Eschenbach showed a plot of the solar irradiance that impinges at the…
Splicing Clouds
Guest Post by Willis Eschenbach So once again, I have donned my Don Quixote armor and continued my quest for a ~11-year sunspot-related solar signal in some surface weather dataset.…
Study: lack of cloud physics biased climate models high
The Hockey Schtick brings this to our attention. It seems Dr. Roy Spencer was prescient with his observation: “The most obvious way for warming to be caused naturally is for…
Evidence that Clouds Actively Regulate the Temperature
Guest Post by Willis Eschenbach I have put forth the idea for some time now that one of the main climate thermoregulatory mechanisms is a temperature-controlled sharp increase in albedo…
