This is part of a series that Tony Cox and I are doing that references the most important points and papers, as a definitive resource about the evidence. The missing hotspot is not just another flaw in the theory, it proves the models are wrong: not just “unverified”, not just “uncertain”, but failed. Apologies to those who feel I harp on about this! This is a condensed review, squishing years of a scientific battleground down to it’s bare bones… — Jo
It is not well known that even the IPCC agrees that the direct effects of CO2 will only increase world temperatures by 1.2°C. All of the projections above that (3.3°C , 6°C etc) come from model projections based on assumptions of what water vapor and clouds will do (these are the feedback effects of the original 1.2°C).[i] Are the feedbacks correct?
If the IPCC models are right about the feedbacks, we would see a hot spot 10km above the tropics. The theory is that with more heat, more water will evaporate and rise, keeping relative humidity constant at all heights in the troposphere. The point has been conclusively tested with 28 million weather balloons since 1959.[ii]

(I’m revisiting older important papers and setting up resource pages, largely thanks to Tony Cox’s prodding. In this post I found it interesting that Lindzen’s work, which was so controversial because it proved the IPCC is wrong, was in many ways merely confirming earlier results. — Jo) Guest Post: Tony Cox and Jo Nova Satellite measurements agree with the ocean heat content measurements. As the Earth warms, more radiation escapes to space.
If feedbacks are positive (as the IPCC estimates), then as the Earth warms the amount of energy being radiated to space will shrink (thus warming the Earth even further). If feedbacks are negative, as the Earth warms more energy will radiate away.
Multiple studies show that feedbacks are negative.
Lindzen and Choi analyzed short periods of warming looking for changes in the outgoing long-wave radiation leaving from the top of the atmosphere. The satellite observations show, repeatedly, that as the Earth warms, the climate system shifts and lets more of the infra red or long-wave energy out to space.[1],[2] It’s like a safety release valve. This means that the system has negative feedbacks (like almost all known long-lived or stable natural systems). The changes dampen the effects of […]
Ladies and Gentlemen this is the front line trench of modern science. If climate science is so important, and there is no time to waste, why does the system try so hard to discourage dissent (because they don’t want to find the truth, only the “correct” answer)?
This paper by Lindzen and Choi was submitted and rejected by GRL in 2009, then rejected twice more by PNAS. (And in part because it needed to meet impossible standards. In the end, it was supposed to include “the kitchen sink” but fit into a sandwich bag — see below). The paper could have been out for discussion in 2009, and while it has improved upon revision, was it worth the two year wait? Those gains could have been made in two months (or two weeks) online.
Even the reviewers understand how significant these results would be if they are right. One admits the new paper shows the models don’t match the observations.
Science needs free and open criticism, and competing theories. If Lindzen’s analysis is revolutionary, but potential wrong, is it so bad to publish those results? He is one of the most eminent researchers in the […]
UPDATED (see below)
Richard Lindzen is unarguably one of the top meteorologists in the world, with over 200 publications to his name, as well as awards, medals, prizes and is a member of the NAS, AAAS, AGU, AMS. He is The Alfred P. Sloan Professor of Atmospheric Sciences, Massachusetts Institute of Technology and his work includes major contributions to our understanding of the Hadley Circulation, small scale gravity waves on the mesosphere, as well as atmospheric tides and oscillations in the tropical stratosphere. From the beginning, he has questioned the claims that there is a crisis due to carbon dioxide emissions, pointing out that even with the poor resolution of ice cores back in the 1980’s it was still evident that there was a lag—as temperatures declined, carbon stayed high for thousands of years, something which didn’t sit well with the idea that carbon had a strong and constant force on the climate.
What follows are his thoughts on the current state of the science. They must make it awkward for those who can’t help themselves but believe in authority. Here’s a man who knows more than most of us could ever hope […]
