Lindzen's views seem to have departed further and further from the mainstream over the years, to the point where he's now sometimes saying things that are flat-out wrong. Here's one of his recent essays: http://www.cato.org/pubs/regulation/reg15n2g.html in which one will find: > The main absorbers of infrared in the atmosphere are water vapor and > clouds.

This is a common talking point amongst the professional naysayers but Linzen should know better.
