There's a HUGE discussion going on in the blogosphere about the global warming data. My dad keeps sending me links on it.
I couldn't care less. If people that I respect say that that there isn't global warming, then okay. For the record, I need more evidence that than commentary from Powerline and Little Green Footballs.

Hey, I’m having this same with my husband (almost identical, actually, down to the links to Powerline, which I also said I would take as absolutely no authority whatsoever). My husband is actually quite knowledgeable about the subject (in a very ancient history, he actually modeled chemical reactions in the upper stratosphere, or something like that). So, it’s particularly frustrating when he sends me links to Powerline to prove something. Next, I ask him, will he send me something from Fox?
McArdle alluded to the discussion (which concerns the release of emails of a climate change institute in England) and dismissed it the same way that I would. Nothing that’s been released suggests that the practice of the science in the field is any different than in any other field.

I’ve read a number of threads on this, and I’ve seen several people state that the computer code used for the models is very amateurish and ad hoc. I wouldn’t know, myself, but it’s one angle of approach that would be accessible to a technically savvy non-climatologist.

My experience with people who know computer code is that they are quick to announce their superiority to anyone else. Climatologists aren’t necessarily code people; there is a certain amount of statistical know-how that needs knowing, but basically, when you do research, you rely on existing products, no? You don’t create code from scratch.
I’m a little sensitive on this subject and sympathetic to the scientists. In another life, my e-mail was hacked and the results were upsetting and thoughts were attributed to me that were taken out of context.

When it comes to coding, being “amateurish and ad hoc” does not necessarily mean the resulting calculations are incorrect. It could mean it’s not elegantly coded, or difficult to maintain over time (which again does not necessarily impair accuracy), or may perform sluggishly, not scale up, etc. You would have to see their QA plans and results to really know how bulletproof their work was.
I guess I see why even highly rational people are so eager to disavow global warming research. It’s really scary.

I can assure you that the climate models are not “amateurish and ad hoc.” Hundreds of people have spent years building up a base of climate modeling software, validating it along the way in comparison to the data we have from other sources. Some of the software is written in Fortran, which may be where the snide comments are coming from. But there hasn’t been any push to re-write all the code in some newer language because re-writing thousands of lines of code is a huge job, and then it will all need to be extensively re-validated before the results can be used. It’s easier to keep on training grad students in Fortran.
As Paul Krugman said on the Sunday morning policy wonk panel, those leaked emails are academics talking to each other. This is no different than the side conversation in any academic field. And probably in business, too. Can you imagine if the emails of CEOs with snide comments about their competitors were revealed?
Science is not some golden perfect one-time experiment, it is a process of proposing hypotheses, testing them, learning from your results and moving forward. Climate change science has a strong basis in fact, even if some of the details are still under discussion.

There’s lots of history of settled science and its defenders: Agassiz at Harvard against the Darwin theory of evolution, Lysenko and Lamarck for inheritance of acquired characteristics, gastroenterologists against infectious origin of ulcers, Lewontin and Gould et al against Wilson and sociobiology, and later against Jensen/Murray/Herrnstein on heritability of IQ. When I was a kid, there were inert gases, and one day suddenly somebody had made xenon hexafluoride – that one didn’t get much resistance, as you could see the crystals. Prions as a source of mad cow, that upset everybody, that proteins could replicate without nucleic acids. That one was messy. Copernicus, Galileo. Often, the settled science is absolutely right, and the challengers are obsessed nutters, I think the cold fusionists and AIDS-not-from HIV people would be in that area. So is Al Gore the new Trofim Lysenko? Is Phil Jones Alfonso X, making ever more complex epicycles?
Comments above sneer at Powerline, and that’s not where I’d look for knowledge, either. I have had doubts seeded by Warren Meyer at Coyote Blog, who has photoed a number of the temperature measuring stations and pointed out that they have been surrounded, over time, by asphalt parking lots and that this seems a plausible reason that temps recorded have gone up in the same location.
It seems to me that the attempts to squelch other views were unseemly, as was discarding that raw data. It’s prudent to try hard to reconstruct these conclusions from the ground up, and by folks who aren’t determined going in to produce their desired answer, before we spend trillions of dollars reconstructing the economy.

We’ve circled around this issue of science-based decision making on a bunch of other issues. Most recently, I encountered it on the report on established/emerging/useless (they didn’t use the last word) treatments for autism. The immediate fear in the autism community was that the decision making was financially motivated (i.e. saying that expensive treatments were emerging) and that the political decision makers would draw the line between what they would pay for between established and emerging. The intent of the scientists was certainly neither of those things . They were looking at the evidence, and some expensive treatments made it into the established list. They chose the word “emerging” to suggest that these treatments deserved further study.
But these nuances of science get translated into binary decision making (both in evidence based medicine) and in public policy. So, the scientists doing the science end up explaining, over and over again, why the nuances don’t make a difference for the big conclusions (for example, the asphalt around temperature sensors, which they are aware of and correct for).
Now, in spite of this understanding, I think these guys were playing a version of the game that I think is wrong — the explanations for the non-release of data are standard, among competitive j*ks who do not want to release their data, and, unfortunately neither journals nor granting agencies do a good job of enforcement (for selfish motives of their own). I’d rather people were more generous with data they control (remember the dead sea scrolls — that was terrible). I think that when people show an example, they should show their “average” rather than their best. But, those are all pretty standard elisions of purity. They rarely undermine the overall conclusions (and there’s no reason to believe that they have in this debate).

Very nice. I stumbled on it following Laura’s links to LGF. It’s cited, and addresses the things the skeptics will bring up head on. It’s going to be a good one to share.
BTW, the questions need to be kept separate in a scientific analysis. 1) is there a global rise in temperature? 2) is this change a new trend, or part of a cyclical pattern? 3) is the global temperature change a result of changes in CO2 concentrations? 4) is the change caused by human activity? 5) is the change caused by human production of CO2. Those are some questions about global warming.
What to do about it is a separate question, and where the real debate should lie.

There are huge distributional differences in how fast you transition and how you encourage/require that transition. That’s why I tend to assume the alarmist language is at least partially a ploy. Those putting out the alarmist language aren’t the ones who are going to be paying more of the cost of the transition so they want to start the transition before working out the details. Those more likely to pay the costs are going to want to hammer out more detail before starting.

Unfortunately, delay can always be an answer to anything — I’d say the right debate, from the point of view who either feel alarm, or think that something needs to be done, is to distribute the pain. Moving away from coal, for example, shouldn’t fall solely on the shoulders of the miners. Demanding that China limit it’s CO2 production can’t ignore the fact that China’s per capita emissions are 5/person and the US, Canada, and Australia are over 20/person. We need to talk about these things, and the costs. But, the details are irrelevant to the big picture that CO2 emissions are causing unprecedented global warming.

Yeah, that’s true, and the people in China feel that way about your car and refrigerator. But knowing that doesn’t avoid the issue of what to do if there’s a real and significant threat, one that can only be addressed very slowly. I think folks who want delay have to think about the math and what it means, too. Yeah, some of them might decide a p(of destruction of human civilization as we know it in X years (where X is sufficiently large and p is sufficiently small) is fine and dandy, but I want to hear that argument made straight out with different proposed p’s and X’s. We can balance those against present day costs, for everyone.
I for one, believe that hydro & nuclear (two non-CO2 emitting power sources that are not a favorite among environmentalists) & “clean coal” (i.e. coal sequestration) have to be explored further. That’s one of the points of the MacKay book — that small scale changes (don’t plug in your mobile phone, turn off the lights, turn the temperature down) aren’t going to reduce CO2 emissions significantly enough to make a difference.

MH, you may be right that scientists funded by industry would have a harder time getting their work accepted by peer review.

You talk about transitions and speeds of change, and that is all important to work out as part of the details of our response, as BJ said.

That sounds horribly plausible. Take, for example, the upshot of Cash for Clunkers (which was in part inspired by global warming fears, as well of course by the desire to prop up the US auto industry):
1. cheap, viable older cars were destroyed and removed from the market where they could have served poor folk as survival transportation
2. the carmakers got a temporary spike in sales
3. in a shaky economy with 10% unemployment, buyers lured in by Cash for Clunkers got tied down to a $400-a-month payment for the next 60 months (that’s approximately average for US car loans)
4. taxpayers have to pay $4500 per car engine destroyed
Cash for Clunkers was a bad idea on so many different levels, but I think that’s what we’re going to get more of if we jump from the science of climate change to the policy without an intermediary stop in economics or common sense.

Here’s an article on the damage done by the ethanol experiment:
http://www.washingtonpost.com/wp-dyn/content/article/2008/04/21/AR2008042102555.html
I’m a new subscriber to Mother Earth News (I subscribed because I liked a newsstand issue on gardening). Upon moving to Texas two years ago and having to deal with three $400+ electric bills in a row our first summer, I became suddenly very interested in geothermal (it’s 65 degrees deep down under the surface!) and solar water heating (although that’s basically what happens in the summer naturally–our water heating bill shrinks to nothing because it comes in warm). I’d also eventually like to set up a water capture system, because while it rains a lot here, it would be nice to save some for when we need it and I despise paying for water. In actual practice, as we’ve gotten used to local conditions, we’ve managed to cut our summer electric bills nearly in half, through some judicious switches to CF bulbs (mostly in areas where the lights are on a long time, and only after the incandescent bulbs burnt out), as well as by changing electric companies and adjusting to warmer indoor temperatures. We’ll do the LED thing when the time comes. We spend a maximum of about $100 a month on gasoline, and it’s generally quite a bit less than that, despite having a car that’s a bit of a gas hog.
Anyway, my point is that solutions need to be local and individual, bottom-up and not top-down so that
failures can be small, cheap and limited, rather than large, expensive and ongoing (it’s generally understood now that ethanol was a bad idea, but who is going to pull the plug now that midwesterners are used to the money?).
