On the temperature trends issue, I heard someone mention that ocean temperatures have actually dropped slightly in the last few years. Is there any truth to that? If yes, should we address that issue?

So I have to be selective, and also try to touch the main skeptic bases -- which is what I am trying to do. You are right re Lindzen. As he is one of the most credible of the skeptics (he is a very clever person with a top reputation outside of the global warming area) he gets higher priority. Just as an example, I've been involved in some published criticisms of work by Scafetta and West -- one example of the idea that the Sun is the dominant forcing, and this is only one of the skeptics ideas. We have spent weeks on this issue alone. Tom. +++++++++++++++++++ Joel Smith wrote: > Hi Tom > > Thanks for the update.
