I just finished drafting up a blog post entitled 'a cloudy outlook for low climate sensitivity'.  It focuses mainly on the recent Lauer et al. paper which concluded that based on their model, which simulates recent changes in eastern Pacific cloud cover more accurately than global climate models, climate sensitivity appears to be on the high end due to a positive cloud feedback.  But I also discussed a few other papers with similar conclusions in the blog post.

Feedback would be much appreciated.

Oh and I'd also like to get this up in the next day or so, since with John gone there's been a bit of a gap in posts.  I think it's in pretty good shape at the moment, but I always appreciate feedback.

Thanks for that post, Dana. Very informative and well written. Skeptical Science at its best!

Is there any way that you could post a link to a better resolution figure?

Thanks Andy.  As I said in the article, if you click the link I provided to the paper, it's Figure 1 on Page 6.  The file (jpeg) itself is here, where it's clearer, but small.

cloud-feedback on climate-sensitivity were low as some hope, this would only apply to the increase of temperature, but it wouldn't prevent further ocean-acidification, would it?

So, from the "evil twin of climate change" point of view clouds don't really play a role (or am I missing something?). I often have the impression that ocean acidification is kept out of the limelight by "skeptics" as many of their lines of thought like cloud-feedback or geo-engineering don't help with that at all.

Absolutely correct, Baerbel.  Skeptics very rarely discuss ocean acidification for that reason.  While they can hope AGW is wrong somehow or some negative feedback will prevent dangerous warming, it's pretty hard to come up with a reason why ocean acidification isn't still a major problem.  In fact when I've 'debated' the subject with skeptics, usually their main argument is just silly semantics, that the oceans won't become an acid therefore "acidification" is "alarmism".  I've really never seen a valid argument why we shouldn't reduce CO2 to prevent acidification.  I think it's another one of those situations where skeptics just hope it's not as dangerous as scientists think.

We should probably do some more posts on acidification, now that you mention it.  Maybe I'll tackle that next, although it's not a subject I know a terribly lot about.  There is one really good acidification paper I know of, but it's a few years old now.
