Adventures on the East Side
) So that was …. interesting.
First off, I’d like to thank the commenters for all of the suggestions and ideas to the previous post. They were certainly useful. In particularly, the connection with the difficulties faced by evolutionists in debates vs. creationists proved to be very a propos. Our side played it it pretty straight – the basic IPCC line (Richard Somerville), commentary on the how ‘scientized’ political debates abuse science (me, though without using the word ‘scientized’!) and the projections and potential solutions (Brenda Ekwurzel). Crichton went with the crowd-pleasing condemnation of private jet-flying liberals – very popular, even among the private jet-flying Eastsiders present) and the apparent hypocrisy of people who think that global warming is a problem using any energy at all. Lindzen used his standard presentation – CO2 will be trivial effect, no one knows anything about aerosols, sensitivity from the 20th Century is tiny, and by the way global warming stopped in 1998. Stott is a bit of a force of nature and essentially accused anyone who thinks global warming is a problem of explicitly rooting for misery and poverty in the third world. He also brought up the whole cosmic ray issue as the next big thing in climate science.
Update: The transcript is now available – though be aware that it has not yet been verified for accuracy. Audio + Podcast.

Global Warming debate
) 
Along with Richard Somerville (UC San Diego) and Brenda Ekwurzel (Union of Concerned Scientists), I’ll be appearing at a debate on Wednesday (March 14th) about whether Global Warming is a crisis (or not). That might have gone without notice (like most of my public talks), except that our opponents are Michael Crichton, Richard Lindzen and Philip Stott. The preliminary position statements (from me and from Philip Stott) are available on the ABCnews site. It’s sold out, but the proceedings will be broadcast on NPR (for instance, WNYC 820 AM on Friday, March 23, 2007 at 2PM) and there will be a podcast (though I don’t know if it will stream live). There’s an online poll as well for what that’s worth.
I’m quite looking forward to this, but I have to admit to conflicting thoughts. Does participating help perpetuate the idea that global warming per se is still up for debate? Is this kind of rhetorical jousting useful for clarifying issues of science that most people there will only superficially grasp? Can this be entertaining and educational? Or does it just validate the least serious opposition? Is it simply a waste of time that would be better spent blogging? ;)
I’d be interested in any thoughts people might have.
Hurricane Heat
) (
) (
) The big problem with much of the discussions about trends in hurricane activity is that the databases that everyone is working from are known to have significant inhomogeneities due to changes in observing practice and technology over the years. So it’s not surprising that a new re-analysis (Kossin et al, published yesterday) has been generating significant interest and controversy among the hurricane research community (see e.g. Prometheus or Chris Mooney). However, rather than this study being taken for what it is – a preliminary and useful attempt to make homogeneous a part of the data (1983 to 2005) – it is unfortunately being treated as if it was the definitive last word. We’ve often made the point that single papers are not generally the breakthroughs that are sometimes implied in press releases or commentary sites and this case is a good example of that.

Cold Case vs. CSI
) If you are a follower of TV crime shows, it is likely that you’ve come across one of the CSI offshoots (CSI stands for Crime Scene Investigation) and a slightly less well known show called ‘Cold Case‘. In both these shows, difficult crimes (usually murders) are solved using the most up-to-date forensic methods and incredible detective work. However, it will be obvious to even the most jaded TV watcher that the CSI crew get to have a lot more fun with the latest gadgets and methodologies. The reason for that is clear: with a fresh crime scene there is a lot more evidence around and a lot more techniques that can be brought to bear on the problem. In a ‘Cold Case’ (where the incident happened years before), options are much more limited.
Why bring this up here? Well it illustrates nicely how paleo-climate research fits in to our understanding of current changes. Let me explain….
The Physics of Climate Modelling

AGU Hangover
It turns out that there were almost 14,000 attendees at AGU last week, which apparently makes it the largest Earth Science meeting ever held. To be sure, not all of that is climate related – there was lots of seismology, planetary and more theoretical/small-scale stuff, but a lot of it was. At most times there were at least half a dozen sessions that I would have been interested to attend – and they were often discussing overlapping themes.
It used to be that one could go to a meeting like this and get a wide overview of the work being done much more efficiently (and speedily) than reading the journals. However, that is clearly no longer true. And of course, we can’t keep up with all the relevant journal articies in the wider field either, and so how do scientists manage?

Fall AGU
The Fall AGU meeting in San Francisco is always an exhilarating/exhausting (take your pick) fixture of the Earth Science calendar. This year will be no different, and since about half of us will be there, RealClimate will probably be a little quiet next week. Hopefully, we should be able to report on any highlights when we get back.
N.B. If any readers will be attending and want to say hi, I will be giving a talk on ‘Science blogging: RealClimate.org and the Global Warming debate‘ on Friday (PA53A, 13:40, MCS 309).
Update: AGU went well – lot’s of good stuff. The actual RealClimate presentation is available here – it’s pretty basic though (only 15 minutes worth)).
Inhofe’s last stand
Part of me felt a little nostalgic yesterday watching the last Senate hearing on climate change that will be chaired by Sen. James Inhofe. It all felt very familiar and comforting in some strange way. There was the well-spoken ‘expert’ flown in from Australia (no-one available a little closer to home?), the media ‘expert’ from the think tank (plenty of those about) and a rather out-of-place geologist. There were the same talking points (CO2 leads the warming during the ice ages! the Medieval Warm Period was warm! it’s all a hoax!*) that are always brought up. These easy certainties and predictable responses are so well worn that they feel like a pair of old slippers.

Historical climatology in Greenland
Gavin Schmidt & Michael Mann
Extending the instrumental record of climate beyond the late 19th Century when many of the national weather centers were first started is an important, difficult and undervalued task. It often is more akin to historical detective work than to climatology and can involve long searches in dusty archives, the ability to read archaic scripts and handwriting, and even Latin translations (for instance, when going through the archives of the Paris Observatory) (sounds like a recent bestseller, only less lucrative, no?).
