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…

Mathematical Proof of the Greenhouse Effect

As a physicist, I’m as certain of the reality of the Greenhouse Effect as I am that 1 + 1 = 2.

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.

Review of Seim and Olsen paper: “The influence of IR Absorption and Backscatter Radiation from CO2…”

Thus, not only does the calculated irradiance seem in error by about 20% over erroneous use of the Stefan-Boltzmann law, but the known bias of the sensor combined with the…

Study: “Venus was once more Earth-like, but climate change made it uninhabitable”

Despite the unsettling title, the authors are not trying to say Earth will end up like Venus if we don’t mend our wicked ways. But the Forbes article and study…

Comments on Dr. Ollila’s Claims that Greenhouse Effect Calculations Violate Energy Conservation

From Dr. Roy Spencer’s Blog March 12th, 2020 by Roy W. Spencer, Ph. D. Once again I am being drawn into defending the common explanation of Earth’s so-called “greenhouse effect”…

What if there is no Climate Emergency ?

Reposted from edmhdotme What if there is no Catastrophic Risk from Man-made Global Warming ? What if Man-made CO2 emissions are not the “Climate Control Knob” ? What if Man-made…

Arctic Layer Cake

Guest Post by Willis Eschenbach There’s a recent paper paywalled here, called Arctic winter warming amplified by the thermal inversion and consequent low infrared cooling to space. Fortunately, the Supplementary Online…

New WUWT-TV segment: Slaying the 'slayers' with Watts

As readers may know, Dr. Roy Spencer and I have had a long running disagreement with the group known as “Principia Scientific International” aka the Sky Dragon Slayers after the…

Great moments in activist climate science – NRDC's Dr. Laurie Johnson: 'CO2 makes your car hot'

People send me stuff. This makes Bill Nye’s recent CNN fail look almost forgivable. My friend Lars Larson, who runs a nationally syndicated radio show out of Portland, OR sent…

The Spencer Challenge to Slayers/Principia

Dr. Roy Spencer has made a challenge to the Slayers/Principia folks who keep insisting the greenhouse effect doesn’t exist at all. For example, see the front page claim at right…

The R. W. Wood Experiment

Guest Post by Willis Eschenbach Pushed by a commenter on another thread, I thought I’d discuss the R. W. Wood experiment, done in 1909. Many people hold that this experiment…

Myths and Facts about Global Warming

From Friends of Science. Be sure to visit their page and bookmark it. COMMON MISCONCEPTIONS ABOUT GLOBAL WARMING MYTH 1:  Global temperatures are rising at a rapid, unprecedented rate. FACT: …

Earth's entire thermal infrared spectrum observed

From AGU highlights, interesting, but readers should note that this is one point on Earth in Chile, not a summation of the  atmospheric absorption, emission, and transmission of infrared radiation…

Clive Best gives evidence for negative water feedback in Earth's climate system using the faint sun paradox and CRUTEM4 data

Excerpts from Evidence for Negative Water Feedback by Clive Best Abstract: Positive linear climate feedback for combined water effects is shown to be incompatible with the Faint Sun Paradox. In…

Pilot video for a series: Bill Scientific – "The Greenhouse Effect"

Guest post by Bill DiPuccio, Science Teacher Let’s face it, high school science videos can be boring and ineffective. I like my science with a twist of comic exaggeration. So…

The UK Independent asks: "Is catastrophic global warming, like the Millennium Bug, a mistake?"

I remember vividly the panic leading up to year 2000. People were racing to Y2K their computers and systems. TV news crews had reporters stationed at bank machines, at train…

Support for the saturated greenhouse effect leaves the likelihood of AGW tipping points in the cold

From The Hockey Shtick, word of a new paper that supports Miskolczi’s theory of saturated greenhouse effect. We’ve seen this before, in the form of this graph. In 2006, Willis…

Unified Theory of Climate: Reply to Comments

Foreword – I’ve had this document since January 17th, and it has taken some time to get it properly reproduced here in full due to formatting issues. Some equations have…

A Matter of Some Gravity

Guest Post by Willis Eschenbach A couple of apparently related theories have been making the rounds lately. One is by Nikolov and Zeller (N&Z), expounded here and replied to here…

Unified Theory of Climate

Note: This was a poster, and adopted into a blog post by the author, Ned Nikolov, specifically for WUWT. My thanks to him for the extra effort in converting the…

Warming 101 primer

Submitted by D.B. Stealey This article went viral when it was first published. Well worth reading: “Our planet has been slowly warming since last emerging from the “Little Ice Age”…

Visualizing the "Greenhouse Effect" – Molecules and Photons

Guest Post by Ira Glickstein This series began with a mechanical analogy for the Atmospheric “Greenhouse Effect” and progressed a bit more deeply into Atmospheric Windows and Emission Spectra. In…

Stratospheric water vapor at Boulder up slightly in 30 years

Via press release from the AGU: Stratospheric water vapor increase at Colorado site Water vapor in the atmosphere is responsible for a significant portion of the greenhouse effect, and even…
