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…

The IPCC, 1990: "Detection of the Greenhouse Effect in Observations" – at odds with the 1988 Senate testimony of Dr. James Hansen?

I’m rather tired still from my trip, and so I don’t have the energy to get into a detailed read and analysis of this document which was posted up on…

Visualizing the "Greenhouse Effect" – Emission Spectra

Guest post by Ira Glickstein The Atmospheric “greenhouse effect” has been analogized to a blanket that insulates the Sun-warmed Earth and slows the rate of heat transmission, thus increasing mean…

Visualizing the "Greenhouse Effect" – Atmospheric Windows

Guest post by Ira Glickstein A real greenhouse has windows. So does the Atmospheric “greenhouse effect”. They are similar in that they allow Sunlight in and restrict the outward flow…

Visualizing the "Greenhouse Effect" – A Physical Analogy

Guest post by Ira Glickstein Albert Einstein was a great theoretical physicist, with all the requisite mathematical tools. However, he rejected purely mathematical abstraction and resorted to physical analogy for…

New paper – "absence of correlation between temperature changes … and CO2"

WUWT readers may remember way back when…I posted this from Joe D’Aleo: Warming Trend: PDO And Solar Correlate Better Than CO2 Joe wrote then: Clearly the US annual temperatures over the…
