A case against precipitous climate action

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 […]

Found: the hot spot? Not

The gap between real world data and thermometers is a make-or-break issue for the AGW theory. The models predict a hot-spot in the atmosphere above the tropics, but the weather balloons (called radiosondes) can’t find any sign of it. Most claims that the hot-spot has been found are not providing any new data, they are just massaging the same old numbers with a different statistical tool. Here are three variations (though the third is not a statistical-spin, it’s just nonsense).

1–Some AGW supporters claim that Santer et al has found the hot-spot. But his paper boils downs to a statistical reanalysis that suggests that due to noise and error, the hot-spot might be there. Santer hasn’t actually found the missing hot spot. He has a case, but it’s not a strong one. The statistical counterargument is at Climate Audit.
