Debunking the myth that a key fingerprint of CO2-induced warming is missing. Updated Jan 2010 |
"The expected 'hotspot' in the troposphere is missing" This is a very technical argument, but it has been adequately debunked. See http://scienceblogs.com/In short, the "hotspot" is not a predicted fingerprint of warming due to increased GHGs. It is predicted to exist regardless of any warming or any cause of such warming. So its absence did suggest the models are not perfect, but it did not point suspicion away from GHGs. Recently it has been shown that the measurements were unreliable, and the hotspot has now been found. See also http://www.csiro.au/news/Are-Climate-Models-Inconsistent--ci_pageNo-2.html. |
