In lieu of an actual climate change post, I'll just quote myself
TN writes, "I can find no evidence that you or any of the other prominent bloggers and columnists we cited have ever publicly rebuked Romm for his behavior, which is toxic to civil and healthy democratic discourse."
Nice addition of the "we cited" escape clause. If you look a little more broadly you get William Connolley at Stoat who went after Romm quite harshly long before your post here:
Now the funny thing about that is what Connolley had to say about the Superfreaks and how it contrasted with your approach:
"Joe Romm has a fairly characteristic attack; and just for a change I'll agree with him; though he chooses odd bits to assault."
Personally I think Connolley is over-harsh with Romm, while I also think Romm is insufficiently cautious about his interpretations of what he's learned.
It's more than clear, however, that Superfreaks wrote a horribly-flawed chapter. While I'm no one of consequence, I was able to write three posts critiquing Levitt and Dubner without once referencing Romm, and I doubt I'm the only one.
I think the most telling part of TN's post was citing favorably to Jon Stewart's puff-piece interview of Levitt, the shoddiest work I've ever seen from Stewart. It was a content-free response that ignored the many substantive criticisms to the chapter, and here we see it repeated again, beyond a few cursory acknowledgments of errors.
I've been meaning to write some kind of open letter to Joe Romm saying "don't blow it with your increased visibility, and be more cautious about your interpretations of facts". Maybe this will have to do. He can keep the vitriol if he wants, but he needs to be more careful on the factual interpretation.
UPDATE 2: post edited to lower the tone, remove unnecessary wisecracks on my part.

TigerHawk's right - Obama should apologize to conservatives about the state secrets privilege
The CIA had invoked the state secrets privilege, insisting that the case against one of its agents be dropped because he was working covertly and his identity couldn't be revealed. And they keptinsisting that even after his cover had been lifted. When Lamberth found out, he was not a happy judge.
More here. This is yet another data point that restates the obvious: just because the government invokes the state secrets privilege doesn't mean there really are state secrets involved. Congress and the courts, who know this perfectly well, would be wise to demand a wee bit more judicial oversight in these cases instead of allowing the executive absolute discretion. Pat Leahy's State Secrets Protection Act would be a good place to start.

First response to Williams and Zabel's anti-cap-and-trade legislation
Barack Obama wasn't on the ballot yesterday, and he won't be on the ballot in 2010. If his voters stayed home last night, many politicians will take that as proof that they'll stay home in 2010, too. That doesn't just make the map harder for Democrats. It also moves Democrats to the right, as their consultants will explain that a winning coalition requires more voters from relatively conservative blocs, like seniors and downscale independents, and thus a more centrist campaign strategy.

Superfreaking lame response on global cooling issue
The chapter opens with the “global cooling” story — the claim that 30 years ago there was a scientific consensus that the planet was cooling, comparable to the current consensus that it’s warming.
Um, no. Real Climate has the takedown. What you had in the 70s was a few scientists advancing the cooling hypothesis, and a few popular media stories hyping their suggestions. To the extent that there was a consensus, it was that there wasn’t much evidence for anything, and more research was needed.
The real purpose of the chapter is figuring out how to cool the Earth if indeed it becomes catastrophically warmer. (That is the “global cooling” in our subtitle. If someone interprets our brief mention of the global-cooling scare of the 1970’s as an assertion of “a scientific consensus that the planet was cooling,” that feels like a willful misreading.)
The headlines have been harrowing, to say the least."Some experts believe mankind is on the threshold of a new pattern of adverse global climate for which it is ill-prepared," one New York Times article declared. It quoted climate researchers who argued that "this climatic change poses a threat to the people of the world."A Newsweek article citing a National Academy of Sciences report, warned that climatic change "would force economic and social adjustments on a worldwide scale." Worse yet, "climatologists are pessimistic that political leaders will take any positive action to compensate for climatic change or even to allay its effects."Who in his or her right mind wouldn't be scared of global warming?But that's not what these scientists were talking about. These articles, published in the mid-1970s, were predicting the effects of global cooling.Alarm bells had rung because the average ground temperature in the Northern Hemisphere had fallen by .5 degrees Fahrenheit (.28 degrees Celsius) from 1945 to 1968. Furthermore, there had been a large increase in snow cover, and between 1964 and 1972, a decrease of 1.3 percent in the amount of sunshine hitting the United States. Newsweek reported that the temperature decline, while relatively small in absolute terms, "has taken the planet about a sixth of the way towards the Ice Age average."The big fear was a collapse of the agricultural system. In Britain, cooling had already shortened the growing season by two weeks. "[T]he resulting famines could be catastrophic," warned the Newsweek article. Some scientists proposed radical warming solutions such as "melting the arctic ice cap by covering it with black soot."These days, of course, the threat is the opposite. The earth is no longer thought to be too cool but rather too warm.

Pressure's on the Silicon Valley Chamber of Commerce
U.S. Chamber is a dinosaur on climate changeSilicon Valley's future, and the nation's, is clean technology....But the U.S. National Chamber of Commerce, which purports to be the voice of the nation's businesses, has turned into a dinosaur when it comes to clean energy. The chamber's strong opposition to climate change legislation makes clear its allegiance to the destructive oil- and coal-based industries of yesteryear.
PG&E took the extraordinary step of quitting the chamber earlier this month because of its "extreme rhetoric and obstructionist tactics." Valley companies and venture capital firms that have been proclaiming green credentials should follow suit. And the San Jose Silicon Valley Chamber of Commerce, along with other Bay Area branches, should make it clear that unlike their national umbrella, they look to the future.
....
The San Jose Silicon Valley Chamber of Commerce expects to take a position on this by the end of the year, according to Pat Dando, president and CEO. It has had discussions with the U.S. Chamber and the California Chamber as well as PG&E and several other members.
But on Friday, Dando clearly separated herself from the national chamber, saying that "there isn't anyone who doesn't realize that climate change is a man-made phenomenon and something we need to address and address quickly."
She says the position taken by business, legislators and community members on this issue may be the most important legacy this generation will leave for our grandchildren and great-grandchildren.
She's right.
We hope her organization agrees, and that individual valley companies make their voices heard in Washington — whether through the national chamber or despite it.

Greening the Chamber: the current Board of Directors is a challenge
- President and CEO Thomas Donahue: as the guy in charge, I assume he's personally responsible for the know-nothing approach, a Lee Raymond type who won't change except under threat to his career, if then. Also, former president of the trucking industry association.
- Chair Robert Milligan: runs an "animal and meat protein processing company" in the Midwest. Not likely receptive to the problems of climate change to meat use and the fertilizer intensive agriculture that supports it.
- Vice-Chair Thomas Bell: a mystery on the Chamber's page. According to Forbes, he's working for property owners, a theater chain, and a natural gas distributor. Could be a prospect, I suppose.
- Donald Shepard: an insurance guy - a possible realist? Unfortunately his background is life and pension insurance, but maybe he's been infected with some understanding of what property insurers think of reality.
- Steve Van Andel: from Amway, which isn't a problem, but also very Michigan-oriented, which could be.
- Those are the above-the-fold directors, then a huge list of others here. I don't have the hours of time to go through them all here, except to notice the first guy is from the Black Chamber of Commerce, who embarassed himself while insulting Barbara Boxer some months back.

Indigenous environmental damage and environmentalism
I've been interested for a while now in variations of the idea of prehistoric environmental damage and environmental management. There's no debate that island-hopping humans killed off many flightless bird species long before European sailors started doing the same thing. The evidence that humans killed off ice-age mammals in North America and that Mayan overuse of the environment caused their collapse also seems pretty strong to me.
The general concept would be that ancient humans exploited and damaged their environments to the full extent that their technology and population levels would allow - in other words, just like us. The main difference from moderns is their technology stabilized or changed slowly, limiting human populations, and a new equilibrium was reached until European peoples and technologies were introduced.
The few exceptions to this rule, where indigenous peoples could have damaged their environment but didn't, are even more interesting. The Polynesian concepts of taboos, tapu, and rahui all protected resources.
Another potential exception that I haven't seen discussed is salmon fishing. While native cultures couldn't wipe out salmon runs on rivers, they could do so on small creeks. The fact that they didn't is pretty interesting, and something I'd like to know more about. Maybe some other examples are out there, too.
And with that, I'll be traveling for a while, so no posting for ten days or so.

Nice to see Watts Up taken down a peg
To be completely accurate, YouTube presumably hasn't reviewed the copyright issue, instead they're just following DMCA procedures that allow them to restore content automatically without them being held liable. Watts theoretically could still bring a copyright claim against Sinclair, but the fact that he hasn't in the time period since Sinclair's counternotice went up suggests that Watts knows he has no case.
Apparently Watts hasn't said anything more on his site, which also suggests he's figured out the score.

What "torture doesn't work" actually means
1. "No accurate and useful information has ever been given by detainees while being tortured." No one, except for the shallowest, self-satisfied strawman builder would give the statement this possible meaning.
2. "The value of useful information given during torture is hidden and overwhelmed by the false information and false leads given during the detainees' attempt to stop the torture." Some people believe this; I don't know whether it's true.
3. Variation on number 2 above, adding "the torture prevents opportunities for rapport-building techniques that get better-quality information with fewer false leads." I think this is what expert interrogators actually believe. I suspect they're right except for the never-happened hypothetical ticking nuclear bomb situation (one other possible exception: during actual combat, where capturing an enemy soldier in the middle of a firefight could give very useful information).
4. Variation on number 2 above, adding "the interrogators are are also likely to believe the false information given by the detainee because the detainee is seeking to give the response that the interrogator wants to hear." I think this is what happened with a number of detainees who were willing to say Al Qaeda was tied to Saddam, and the interrogators actually believed it.
5. "The value of any good intel from torture is far outweighed by the harm done to the effort to win hearts and minds and separate the terrorists from public support." This is an independent reason that complements numbers 2 through 4 above and is the one that settles it, in my opinion. Of course, right wingers and the faux moderates who position themselves on interrogations could care less about what is the actual road to victory.

A tangent about additional rightwing nonsense: in discussing the National Review's current semi-defense of its 1964 opposition to civil rights, WF Buckley's alleged renunciation of prior racist views came up in the comments. I wrote a follow-up comment saying that I find much mention of his renunciation, but no actual quotes. If anyone's seen where Buckley comes clean, I'd like to know.

Chuck Grassley and stratospheric cooling
GRASSLEY: Well, I’d be foolish if I didn’t give—I’d be foolish if I didn’t give it some consideration because there’s a massive amount of scientists that feel that it does. But there’s also an increasing number of scientists that have doubt about it.
And so, not being a scientist, I don’t know exactly where to say only those things that are really quantifiable, and temperature has risen. But the scientific aspect that I still reserving judgment on is the extent to which it’s manmade or natural.
.....
Now, a lot of members of Congress and most environmentalists are—are absolutely convinced manmade is the—is the factor—chief factor here. But I—I want to, before I vote on it, be more conclusive in my judgment, and I haven’t reached that conclusion at this point.
Roberts is justified in feeling frustrated, and the arguments do read like multiple excuses for not doing the right thing. OTOH, Grassley's not using the "global warming is a hoax" language that Inhofe does. I think that it would at least be worth a shot to try and convince Grassley that there's no reasonable doubt about human-caused change.
One of the most persuasive arguments for why climate change is human-caused, I think, is stratospheric cooling. The reason why greenhouse gases cause stratospheric cooling is complicated (one explanation here, I'd welcome better references) and I don't think I've got a good grasp on it yet, but the key aspect is that solar influences can't explain why the stratosphere is cooling.
If you look at the first two images in this RealClimate post, one shows warming from greenhouse gases, and the other from solar radiation. At the top of each image, only greenhouse gases also show stratospheric cooling. If Grassley wants evidence, there it is.
What do the denialists have to explain the cooling? Nothing, that I can tell. There's a hilarious attempt by Steve Milloy to actually deny cooling through cherry-picked start and end dates that a fifth grader could spot (and even then I'm not sure his trend line fits the data). Not sure if anyone else has tried.
Milloy has no interest in the truth that I can tell, but there are some skeptics out there that actually believe what they say. I should ask them what they think.

Chimps like magic
All very entertaining, but also a demonstration of the chimp's intelligence. It's easy to get a surprise reaction in animals by startling them, but I don't think a dog or horse has enough of a mental framework of the universe to notice that something had just gone very wrong in each of the tricks. Also worth noting how young the chimp is - I'd guess about three years old or so, and probably as far away from adult mental development for chimps as a six year old human would be from adult intelligence.
Entertaining and maybe enlightening. I guess I should also wonder though about what happens to the chimps when they're not so small and cute.

$30-$60 million campaign to get climate legislation passed
In the latest one, they say the major enviro groups have gotten together and are hoping to raise $30-$60 million in a public campaign to get climate legislation passed. That's what a presidential campaign used to cost, not long ago. And while it sounds like a lot, they're also saying "In the first two quarters of 2009, Big Oil and other polluters have spent nearly $120 million trying to defeat clean energy legislation and will stop at nothing to do so."
Supposedly the groups are doing joint fundraising with money specifically dedicated for this campaign, but I can't see where they're doing it, or I'd kick in something. Anyone who knows more, please comment.

Random (non-climate-related) miniposts
"The word Fascism has now no meaning except in so far as it signifies 'something not desirable.'" From George Orwell in 1946, a generation before Jonah Goldberg's birth.
Same Facts has posted about the rightwing fascination with bringing guns to presidential events. Eddie Murphy anticipated the issue years ago (starts near 1:45, note the NSFW language).
UPDATE: I think Glen has a decent point in the comments, that two or three gun-toters doesn't equate to the entire conservative movement. OTOH, I think the widespread conservative defense of bringing guns to presidential appearances is pretty wacko.

More on the Mackey/Whole Foods boycott
Some thoughts:
1. If Mackey owned Whole Foods instead of working for it, I'd have no problem with a boycott and might have to join it myself.
2. Part of a successful boycott strategy is a coherent goal - so what's the goal here, when the boycott target, Whole Foods, has done nothing wrong? Get it to fire Mackey for his political opinions expressed on his own time? Is that ethical?
3. The ever-nuanced Jonathan Zasloff says what he wants from Mackey is intelligent disagreement, and not to shut him up. Fine, but the demand isn't being made of Mackey, it's being made of Whole Foods.
4. Matt Yglesias says shutting down CEOs from prominence in the public media isn't that bad/unethical anyway as they get undeserved attention to spout off on issues unrelated to their business. So do other people though, like Hollywood liberals. That's life. Anyway, it's Whole Foods that's being punished for something Whole Foods didn't do.
5. Somewhere in the Yglesias comment thread, someone says this isn't about ethics, it's about political maneuvering, and objectors like myself should get off our high horses. Interesting point, but Your "Ends Justifies the Means" Mileage May Vary (maybe I can invent a new Internet acronym, YEJMMMV).
6. Boycotts need both favorable sentiment and an organizer. A "Boycott Whole Foods" group has sprung up, but what they want is unclear. They call for a boycott, but don't say what they want Whole Foods to do. I think a successful boycott requires that the target company know exactly what it needs to do in order to make the problem go away.
7. Boycotts succeed not by turning customers away, but by affecting brand image and taking the time of important people. That's the sole advantage I see here for a boycott, in that Whole Foods relies heavily on its image.
8. The boycott may not be about Whole Foods or Mackey at all, but rather about health reform. That might make it more logical, but I'm not sure if it makes it the right thing to do.
9. Given his past, Mackey seems dumb enough to pull stunts like this again in the future. I remember hearing somewhere that company board members never want to see the company name in the newspaper, unless it's to report on record profits. Either he's really good at what his actual work entails, or the guy will eventually have to go.
*I should qualify these as "tactically" successful. We got the companies to withdraw, but have obviously failed on the broader strategic goal of forcing Burma's dictators to change.

Geoengineering jiu-jitsu and India
Leaving the cherrypickers behind us, I think discussing geoengineering might be a useful wakeup call to policy-makers in India, because the resulting drought effects from spewing sulfates into the atmosphere seems especially likely to hit India hard. If India doesn't want to do anything to stop emissions, then they can think about the consequences. Either with warming-induced loss of a snowpack or with sulfate induced droughts, India isn't getting water. Maybe they ought to consider emission reductions as an alternative, however unfair it might be with Republicans here in the US demanding that Indians produce one-tenth the emissions that they do per person.
Tangentially related is something else that might be useful for India and the black carbon problem beloved by bunnies, and that is home-cooking pyrolysis stoves that get rid of black carbon and leave soil-improving biochar as the result. This is no silver bullet - people have invented countless ways to improve upon traditional cooking fires that haven't been accepted. Biochar is basically charcoal, too, so you have to get people to bury it instead of cooking with it as well. Still, this is worth a shot (and even if they burn it, that's carbon neutral, while burying biochar is carbon-negative).

Defending Whole Foods from John Mackey and a boycott
I don't agree with a boycott. Mackey may be like the evil denialist Lee Raymond who funded anti-global warming astroturf groups when he ran Exxon, but the difference here is that Whole Foods isn't being used by Mackey to fight health care. I don't object to a corporation having a prominent officer espousing stupid beliefs on his own time.
Mackey did go slightly further, putting the unedited version of his op-ed on his part of the Whole Foods blog, but he says he did it to distinguish between his words and the edits by the Journal that made it expressly critical of Obama. IMO he shouldn't have posted it, but simply said that his views are only his own, and at most given a link to some personal blog he could set up independently of Whole Foods and rant to his heart's content.
That's a relatively minor sin, though, and I don't think it should be a requirement that corporations I use have every officer share my views.

Grass-fed beef and greenhouse gas - now with data! (Some data, anyway.)
In that Grist article I talked about earlier, someone named CL Weber showed up with data:
Not looking good for grass-fed beef. Story's not completely over, though. The commenter acknowledges earlier that indirect land use changes aren't accounted for. He or she thinks that could make cattle effects worse, but not necessarily. The main alternative use I'd expect of ranchlands in the San Francisco Bay Area in lieu of cattle would be sprawl. Also it doesn't include soil carbon, which would be a significant benefit I'd expect (maybe) from switching from tilled agriculture to pasturage.J Environ Qual 35:231-239 (2006) compared different types of suckler beef production, while Casey, J. W. and N. M. Holden. 2006. Quantification of GHG Emissions from Sucker-beef Production in Ireland. Agricultural Systems 90: 79-98 .... The JEQ article does indeed show (slightly) lower GHG emissions from organic production, at 11.2 kg CO2eq/kg-yr vs. 12.2-13 kg CO2eq/kg-yr for the conventional production schemes, which is still higher than the 10.8 kg CO2/kg-yr mean value calclulated in the Agricultural Systems piece....
However, again, my point is not that grass-fed is substantially worse than grain-fed but that they're pretty much in the same ball-park GHG-wise, and that the difference between them is in the noise when compared to the difference between beef and chicken (1.4 kg CO2e/kg in the US, according to Pelletier, N. 2008. Environmental performance in the US broiler poultry sector: Life cycle energy use and greenhouse gas, ozone depleting, acidifying and eutrophying emissions. Agricultural Systems 98(2): 67-73.)Obviously pastured beef can have much better impacts on many other things, like water and air quality, than CAFO beef, but a substantial GHG advantage can't be had without assuming large amounts of C sequestration and no land use impacts despite the large amounts of land needed.
Without those effects, beef is nearly ten times worse than chicken, which in turn is probably three times worse than vegetarian (my somewhat-eductated guess). It will take a heck of a lot to make up the difference between beef and vegetarian calories. Some interesting high-tech suggestions on page 120 of this UN FAO publication could be a start, if consumers will tolerate changing cattle's internal biota. Could be a split between the hippie and techno sides of the environmental movement.

Grass-Fed Beef and Methane, Part Deux: Still More Armwaving
Anyway, it was a data-free discussion, which is fine for what it's worth. Now comes a cattle rancher to make the same argument at Grist. To his credit he raises the methane issue, but after asking questions as to ways that, maybe, somewhat reduce methane emissions, concludes as to whether the methane is a problem, "The fact is clear. It is not the livestock; it is the way they are raised."
I may have been guilty of armwaving in my discussion with Michael, but at least I didn't jump from that to a conclusion. I left a comment saying as much, and a later commenter said it better:
It is conceivable to me that a steer that eats only grass from naturally fertilized pasture could have a negative carbon footprint. Root structures of grasses can be quite large, and soil can become a carbon sink, so the pasture could possibly sequester enough carbon to make up for the methane emitted by a steer during digestion. I'm also open to the idea that manure decomposes differently on pasture than at the feedlot. But someone needs to demonstrate it with some actual measurements and some real science.

California gridlock to reach national politics
National politics might be going the same way. Republicans retreat to conservative white base voters in the South, advocate those types of policies exclusively, and can never win the legislature (but might win the executive branch with an exceptional candidate). Senate supermajority rules let the Republicans retain enormous power to block action though.
It could go this way, or the Democrats could ram some decisions down the Republicans' throats, or a few Republicans could do the right thing. And eventually I expect the Republicans will follow the British Tories that they used to admire, but I think they'll have to lose at least two more presidential elections in a row before they become a responsible opposition party.
Other random California thoughts:
- New Jersey corruption shows the problems of a one-party state. This will happen to California too if the Republicans fail to reform themselves. I have trouble imagining ever voting for a Republican for national office, but I have voted for Republicans at the local and state level. If I were from New Jersey, I'd be thinking about doing the same there.
- Great news on establishing no fishing/no abalone diving marine reserves in California. National parks were established a century ago for the same reason: no hunting areas allowed animals to proliferate and spread out to where they could be hunted.
- Finally, the Aptera will soon be available, but only in California. This is the first vehicle I ever really wanted just for its looks, in addition to being electric. Not sure when or if that will happen though.

Using Dispute Finder on Bob Carter
So I downloaded it, signed on, and pulled up Bob Carter's useless "warming stopped in 1998" claim at the Telegraph. Users of the extension now see the claim is disputed, which somehow makes me feel better. I then tried the search function to mark dozens of sites parroting the claim, but that didn't work. Oh well.
I suspect the feature might be more useful for non-obvious disputes, but it still feels good to get it out there.

Mars Opportunity Rover on its way to clay-bearing rocks
The sequence of events as I understand it is that scientists believe that clay rock layers were deposited first. Then a large impact created the Endeavour crater, with crater rims sticking up above the surrounding rock. Then acidic waters left acidic rock deposits that covered the entire area except the crater rim. If Opportunity can get to it - it's still a long way away - it can find a type of surface more life-friendly than anything we've seen before.
I've wondered if the $20m annual cost of extending the rover missions has been worth it, but this would make it worthwhile if the rover successfully gets there.
