Re #8, Dave,
Yep, I cringe when I reread some of my old posts. Steve could add a paypal box for those of us who spent too much time looking out the window during english classes or suffer from bouts of low blood sugar.

It really annoys me that my spell checker can’t even catch “messsages” in your post .

John A. $.05 a word? How about $1.00 per logical fallacy? I’d like to think I’d only be nickel and dimed to death. Some here would lose the house.

Who needs AdSense with ideas like this?

Speaking of making a good impression. It’d be nice if at least the regulars would re-read and correct their spelling, grammar, etc. before posting. These messages are forever, essentially. Messages with lots of error indicate lack of forethought and reflection and therefore are easily dismissed.

I don’t know about the rest of you but I often spend a lot of time on what appear to be hasty posts just deciding what tone to take in a given messsage and I hate it when the occasional typo creeps in.

TCO, John A and others, right now. we’re getting lots of new hits resulting from the NAS Panel and are running at 15-16,000 per day, about 80-100% above normal. I’m going to delete a bunch of posts, including some backbiting. Let’s stay on main topics. There are a lot of people who visit here who don’t post – let’s try to give a little bit of a good impression – OK?

Let’s also not talk about computer screens. Either wait until another day or send emails to me or John A.

shoot write a paper on what type of study should be done. And publish that! Along with the other 20 papers that you are delinquent on. I’m still trying to figure out how much is not liking to write and how much is fear of criticism. I’ll shrink that head, though.

They are a government bueracracy. They fund the trendy stuff. They are unlikely to come to the table to sign up for doing rigorous feild studies unless it is directly funded by congress. Still there is other money out there. There are things that can be done with one-offs (if you frigging PUBLISH them, sheesh.)

#3. I’ve been involved in financing and organizing mineral exploratin projects and I know that end of the business (though there are people much better than me). Logging drill core and doing geology is a different job.

But I was really intrigued by one comment of Alley’s at the NAS panel – that the updating of proxies didn’t really fit with academic projects. I’m sure that I could put together a competitive bid to an update of tree rings in northern Canada (or anywhere else in the world) using geologists to organize logistics – they know how to do everything like that – hire a dendro guy to supervise the field work – get the geologist to do proper mapping and logging, which these guys have poor traditions of – then archive the results as soon as you get them even BEFORE you publish. Now I don’t want to do something like that, I’d never finish what I’m working on, but I could do it. So when I hear all these whining excuses about needing 6 years or 16 years to archive data, or even 2 years, it’s total crap. People got paid to collect the data. Until they got paid, they have a lien on the results, but once they’ve been paid, NSF shouldn’t allow them to hoard the data. While I partly blame the protagonists, most of the blame surely rests with NSF for weak-kneed administration.

Steve, ever considered doing your own feild study? One of the potential problems with all the compiled research is cherry picking. It would seem that doing your own field study, would show that results can be very variable. It’s not about forensically proving a particular individual (e.g. Jacoby) to have cherry-picked, but just to show that variation is larger then believed. It throws the whole enterprise into larger question. If they come back and say, you have to be a left-handed club-ward to know how to do the field work, you can say fine, publish the exact procedure. And until they do, you can keep going out and gathering more field work, to embarres them. Even if your field work justifies them, so WHAT!! That’s science baby.

Second, the scale of variation in Thompson’s decadal series is obviously much smaller than the annual ranges, which are very noisy.

Are the annual ranges really noisy, or is there an real high frequency component that dwarfs the low frequency response in this time frame? I’m assuming that these guys know what kind of repeatability to expect if they collect multiple cores from the same site.

Steve,

I had an opportunity to speak with Thompson last Friday. We both attended a reception after a screening of the Gore film at a theater near the Ohio State University campus. Thompson was being pulled around the reception, thus I could only ask a few questions.

I asked him about my concern that gases might be lost from ice cores (particularly deep cores) when they are brought to the surface. He told me that they try to keep the cores iso-thermal. I explained that I was not concerned as much about temperature effects as I was about gas losses from microfractures. Thompson explained that he has seen no bubbles in deep ice cores. He said that CO2 is in the form of clathrates. He said that after a day or so, bubbles form in these deep cores.

I also asked Thompson what percentage of GW he felt was anthropogenic. He said that he thought it was 80%.
