Update: “Climate Sensitivity Estimates: Heading Down, Way Down?”

By Chip Knappenberger -- November 10, 2009

A previous post at MasterResource described the findings and implications of a new scientific study published by Richard Lindzen and Yong-Sang Choi, “On the Determination of Climate Feedbacks from ERBE Data” published in Geophysical Research Letters.

Lindzen and Choi’s concluded that climate sensitivity to atmospheric greenhouse gas concentrations is six times less than generally accepted—a conclusion that potentially overturns the current paradigm of scientific thinking.

Their paper is now under careful scrutiny–as it should be. As I wrote:

This is a major paper. And as with most findings with serious repercussions to our scientific understanding, it will doubtlessly be gone over with a fine-toothed comb and subject to various challenges. It is too early to tell whether Lindzen and Choi’s findings will prove to be the end-all-and-be-all in this debate.
