Raymond Pierrehumbert has written an excellent overview on infrared radiation and planetary temperature. The article was published in Physics Today, and unfortunately behind paywall. Fortunately, Climate Clash has posted the article in full. I suspect that this article is digest of the corresponding chapter in his new book, Principles of Planetary Climate, which is hot off the press (published December 2010). On a previous thread, Chris Colose highly recommended Pierrehumbert’s treatment of infrared radiation and planetary temperature.
I think Pierrehumbert’s article is very good, and summarizes many of the topics that we have discussed at Climate Etc. on previous greenhouse threads:
- Physics of the Greenhouse (?) Effect
- Best of the Greenhouse
- Confidence in Radiative Transfer Models
- Radiative transfer discussion thread
So, if you have followed the Climate Etc. threads, the numerous threads on this topic at Scienceofdoom, and read Pierrehumbert’s article, is anyone still unconvinced about the Tyndall gas effect and its role in maintaining planetary temperatures? I’ve read Slaying the Sky Dragon and originally intended a rubuttal, but it would be too overwhelming to attempt this and probably pointless. Has anyone else read this?
I’m asking these questions because I am wondering whether any progress in understanding of an issue like this can be made on the blogosophere. Yes, I realize there are a whole host of issues about feedbacks, sensitivity, etc. But the basis of greenhouse don’t seem to me to provide much intellectual fodder for a serious debate. I’ve lost track of the previous threads (with over 1000 comments on one of them); can anyone provide a summary of where we are at on the various unresolved discussions?
I’m really wondering if we can get past exchanging hot air with each other on blogs, learn something, and collectively accomplish something? If you have learned something or changed your mind as a result of the discussion here, pls let us know.
