Here the spacecraft is only 100 km from the center of the moon. (Phobos is only about 25 km in diameter.)
The resolution of this photograph is about 3.7 m/pixel.
The Russian Phobos-Grunt mission, to be launched next year, plans to land on Phobos and return a soil sample to Earth.
Mars is getting to be a very crowded place.

Sometimes it's scary how many things can go wrong with the human organism -- and I suspect any nondoctor probably doesn't even know the half of it. On the other hand, there is something I find morbidly fascinating by pictures of pathologies, too. The New England Journal of Medicine has a weekly feature called Image Challenge, which is worth perusing if this is also your guilty fascination.

The first thing Evans wrote was
1. The greenhouse signature is missing. We have been looking and measuring for years, and cannot find it.I thought this was one of the primary signatures of anthropogenic global warming...
(bottom three graphs)
Comparing a model to observations doesn't prove the model works. It's encouraging to the model builders, but it's not proof. For instance, the model could just be lucky. (And I'm a model builder!)I don't know how else you could prove a model works, but anyway. He went on:
The GCM models omit cloud complexities. They simply assume relative humidity is constant (observations in the last few decades shows in fact it drops steadily as the temp went up), so as temp rises there are more high clouds....
Also, the GCM models totally omit solar magnetic effects [ie. Svensmark]
Given their omissions, my guess is that the GCMs got "lucky" to get the Fig 9.2 results. For instance, I can make a model of plant growth predict global temperatures if you wish (obviously absurd), with sufficient tuning and funding :)

Mayor-elect Sam Adams accurately states, of The Great Paper/Plastic/Cloth Use Debate: "It's a simple behavioral change that we have to ingrain in ourselves."
And in a free society we do, indeed, ingrain behavioral changes in ourselves, freely, as we, individually, perceive the necessity to do so.
In a totalitarian society, however, behavioral changes are ingrained in the citizens by the government, for ends perceived by the state to be beneficial, or, in this case, by some Little Caesar in City Hall.

Oregon's total electricity consumption in 2006 was 6100 MW, or about 1640 W/person. (Per capita = 14,400 kW-hr/yr.) So this wind power would represent a decent chunk of that.

Here in Portland, every time the state or city decides to spend a few thousand dollars on improvements for bikes, the righty car owners whine and complain that bikes aren't paying their fair share of the roadway. It looks like, in fact, they aren't either -- or rather, that we all are.
Water is a big deal in the west, even in Seattle.

"...one must conclude that no mistake is too dumb for someone, somewhere to make if they think they can spin it into supporting their anti-science agenda. For them complexity is something to be abused rather than a challenge to be understood, underlining quite clearly (again) the difference between science and propaganda."

A city commissioner here, Sam Adams (to become mayor in Jan 2009) is proposing banning them (he floated the idea several months ago), which I think is a good idea. I used to oppose it, for no better reason than that I use those bags for cat litter, but a month ago I bought a clothe sack from Safeway for $0.99 and I have to admit I love it. It's bigger and sturdier, plus you feel you're doing a little good for this crappy world. You just have to get in the habit of taking it with you when you plan to go to the store.
Adams wants to charge 5 to 20 cents per bag if you don't have a reusable sack and use a plastic or paper bag from the grocery. I hope it's 20 cents -- 5 cents isn't enough incentive.
Only 52 percent of the paper and 5 percent of plastic grocery bags given out in the United States are recycled, said Stephanie Barger, executive director of the Earth Resources Foundation in Costa Mesa, Calif.I don't know what I'll do with cat poop once my (humongous) supply of plastic bags is gone. Probably have to buy other plastic bags just for that purpose. That defeats the purpose of the ban somewhat, but at least the bags won't end up in the oceans.
It takes 16 cc of oil to produce one plastic bag; 430,000 gallons to produce a hundred million of them. About 5 trillion plastic bags are used annually, requiring 500 million barrels a year, about 2% of all oil use.

A few years ago my old graduate school officemate Tobias took me and another grad school friend Joe on a tour of SLAC, where he was working at the time. It was a Sunday in the summer and the place was deserted. We got to poke all around and if you ever get the chance to do that in an accelerator (or anywhere, really), be sure to take advantage of it.
Got a copy of Mann and Kump's Dire Predictions yesterday, and spent the evening reading most of it. It's done in an interesting way--not your typical prose book, but an "illustrated guide" with lots of graphs and colorful pictures on glossy paper. And it's structured so that you can pretty much pick it up and look anywhere within and find something interesting to read. You can learn something no matter at what level you already understand climate change, but it would be especially suited for people who are not scientifically-oriented but want a nontrivial introduction to the topic -- below a Scientific American level. Or for kids -- I would have eaten this book up when I was in 7th or 8th grade.

This is the best case scenario if the US, as currently configured, were to try and be oil independent.
"The U.S. Department of Energy estimates that drilling in ANWR would only reduce the price of gasoline by less than four pennies per gallon—20 years from now!"The LA Times has a front-page piece on Peak Oil today, but it doesn't really say anything new -- maybe we're there, maybe not, probably screwed in any case.

First of all, I don't live in the southwest (but in Oregon) and I don't cover the southwestern water beat (I generalize among the physical and environmental sciences).
Anyway, I agree that there are some valuable blog posts out there, covering things that would otherwise be ignored by the MSM. I just don't see them coming from fishbowl blogs like Matthew Yglesias or Andrew Sullivan or Instapundit or anyone who feels compelled to post 35 times a day. They're so worried about the next post and bringing traffic to their sites that they hardly focus on their current post.
These posts too often lack depth, and they go into my brain and immediately bounce back out like a light beam off a mirror. It's like spending all day watching Good Morning America -- sure, once in a while they point to an interesting thing or two, but overall it's a big waste of time.
If, as Frank Lloyd Wright said, television is chewing gum for the eyes, then the blogosphere is increasingly chewing gum for the brain. Which is too bad.
With nothing learned or enjoyed, it's just a waste of time, and they're all little wastes of time but they add up to minutes and hours. They could easily add up to your whole day if you let it--you know exactly what I mean. Is this what 21st century life is going to be -- pinging back and forth between blogs, gossiping about every belch that comes out of John McCain's sixth-in-line advisor, checking the headlines 8 times a day, dissembling what Chris Matthews said this morning or enraged at something stupid Jonah Goldberg wrote on The Corner? This isn't healthy, physically or intellectually, or individuals or for society. Is this really how I should spend my latest half-hour, or should I read a paper from Science, polish the latest draft of a manuscript, or take a walk along the Williamette?
The world has never been more complicated and we've never needed to understand so many issues in so much depth. This medium is the answer. And yet more and more of the Web, and especially the blogosphere, seems to take us away from that depth and offers us tidbit for the microsecond. Yes, there are always a few good posts out there amidst the billions, some by smart and thoughtful writers with unique talents, many by educated specialists who want to share their work and their field, things that might even change the patina of your day. I'm going to focus on what I can learn there, and stop caring what Matthew Yglesias thinks of OpenLeft's latest quip about Instapundit's "heh" placed after today's 16-word anecdote disproving anthropogenic global warming.
Steve Milloy at JunkScience.com does the task here. His minions propagate it forward.
But put the report in context:
- The newsletter is calling for a review and debate, and is hardly a declaration. And in any case, it comes only from the editors of Physics & Society, which is only one newsletter among many at the APS and comes from only one forum of the APS and not the APS itself. I've been following the physics community for years, and until yesterday never even heard of this newsletter.
- In fact, on its front-page today the APS says:
APS Climate Change Statement
APS Position Remains Unchanged
The American Physical Society reaffirms the following position on climate change, adopted by its governing body, the APS Council, on November 18, 2007:
"Emissions of greenhouse gases from human activities are changing the atmosphere in ways that affect the Earth's climate."
An article at odds with this statement recently appeared in an online newsletter of the APS Forum on Physics and Society, one of 39 units of APS. The header of this newsletter carries the statement that "Opinions expressed are those of the authors alone and do not necessarily reflect the views of the APS or of the Forum." This newsletter is not a journal of the APS and it is not peer reviewed.
- If you actually read the newsletter, you'd see that in actuality what they're presenting are two papers, only one of which disagrees with the consensus. The other paper is in agreement with the consensus. So why focus on one or the other? Both papers are mathematical and unlikely to be understood by anyone without a science degree. Therefore people are going to pick the one that backs their ideology.
- I think Monckton cherry-picks his data to show a cooling trend from 2002-2008. I plotted my NASA GISS data and did get a negative slope for the linear regression over this interval. However, if I choose, say, 1998-2008, I get a positive slope.
- One 8-page paper by one scientist hardly undoes the work of hundreds of scientists putting together the evidence for AGW in a thousand-page report.
- CO2 is still a greenhouse gas, still responsible for about 30% of our earth's natural greenhouse effect (33 deg C), and it's basic common sense that more of it in the atmosphere is going to cause higher temperatures.
Of course, that's exactly what Milloy is paid to do, let's not forget.

It's certainly not that I think Matthew Yglesias is vapid or unintelligent or Andrew Sullivan or any of them. They're obviously all very smart guys with things to say, though perhaps limited by the need to post 25 times a day.
I guess I am just disgusted with the superficiality in our society, which has now taken over much of the blogosphere, especially the political blogosphere, which seems to have rapidly sunk into that hole. Maybe you care if Obama's third-to-main advisor has a pastor who once had dinner with a former Black Panther who once quoted Nietzsche when he was a 19-year old sophomore wearing dredlocks -- maybe that's all campaigns revolve around now -- but if so it is an utter fucking waste and I have absolutely no interest in it and I mourn for the death of my country. Paying attention to it all gets me nowhere, and why else to tune in to Yglesias or Sullivan 5 times a day except to find out the latest gossip. Is that what the blogosphere is about now -- gossip? Maybe.
I just don't see that they have much original to say, and so why am I spending my time there and not reading great books by Robert Pirsig and Charles Dickens and Chellis Glendinning and Edward Abbey and Thomas Kuhn and Warren Siegel and Stanislaw Ulam and Updike and Rick Bass and John Irving and Henry Roth and people who are writing for the ages and not for the current 15 minutes?
Yes, there are gems in the blogosphere, issues not discussed anywhere else (and certainly not on cable TV or even mainstream newspapers). But they are farther and farther apart and I can't spend time trying to dig them out.
And Obama, who once seemed like he might be an answer for those ready to give up, is clearly not that at all, but just another one of them. A product of the system, spit out at the top.
Some responses to my rant said that blogging is a conversation, and maybe I'm just not a good conversationalist. I live too much in my head.
Anymore most blogs just feel like things that get in the way of me living my life, really living it, instead of sitting in front of the damn computer for 12 hours a day trying to stay abreast of it all. Fuck it. It's disturbing my life and, I suspect, the lives of lots of other people. All this crap is not life. Instead I'm going to go out for a walk or up to the library or meet a friend for lunch or go sleep in a tent up in the mountains for a few days and get rained on, and then I'm going to focus on what little I can understand and can write about and communicate, in a manner and depth that matters.
I gave up TV a year ago and maybe the blogosphere is next. Who knows, maybe I'm on my way to living off the grid in a small cabin in the Cascade Mountains, a heartbroken hermit, but I just hate wasting my time on gossip and trivialities and every stupid thing they try to divert you with.
There are so many huge issues in our society and it seems clear to me that we are on a precipice and our future really hangs in the balance. Our economy is taking, we are at Peak Oil, 1/6th of the fucking country has no serious access to the health care system except for pitiful clinics at Wal-Mart, we are clearly not going to even begin to address climate change, our youth are wasting their lives in the Middle East securing oil profits, politicians lie rampantly and the media are pussies and those with power are clearly bought and sold by international corporations. We spends hundreds of billions on war, enriching the oil companies and the defense companies, and can't even pay Medicare doctors the minimum of what they're worth. And... I don't know, Americans don't even seem to care. They just go to work and go out to eat afterward, and polls show them to be happier and happier. So why am I getting angrier and angrier?

"A major fight is brewing – it may be called war. On the one side, we find the short-term financial interests of the fossil fuel industry. On the other side: young people and other beings who will inherit the planet. It seems to be an uneven fight. The fossil fuel industry is launching a disinformation campaign and they have powerful influence in capitals around the world. Young people seem pretty puny in comparison to industry moguls. Animals are not much help (don’t talk, don’t vote). The battle may start with local and regional skirmishes, one coal plant or other issue at a time, but it will need to build rapidly – we are running out of time."

But you have to salute them for trying. Climate change is clearly the most serious threat the future has ever faced, besides maybe worldwide nuclear war (and who worries about that anymore?), and it is now clear that the powers-that-be will take no action at all that would threaten the profits of the world's corporations -- or, if they do take any action, it will be so weak and timid as to hardly address the problem at all. It really is a sort of war, and what else can you do except sit back and take it? Protest. James Hansen has called for uprisings from the younger generation whose future is being threatened and perhaps ruined -- it will be interesting to see what he has to say about this.
Mario Savio said, during the Berkeley free speech protest in 1964:
There is a time when the operation of the machine becomes so odious, makes you so sick at heart, that you can't take part; you can't even passively take part, and you've got to put your bodies upon the gears and upon the wheels, upon the levers, upon all the apparatus, and you've got to make it stop. And you've got to indicate to the people who run it, to the people who own it, that unless you're free, the machine will be prevented from working at all!I do think people have given the world's governments enough time to have taken a significant chunk out of this problem -- 20 years now -- and hardly nothing has been done whatsoever.
UPDATE: Here's a video clip of Savio's speech.

I suspect the science of climate modeling has changed a little in the last 11 years.
Why is Climate Change Daily pointing towards 11-year old articles as evidence against global warming? I haven't been very impressed with this site since its inception last year -- I'm not sure I can ever trust it now.
Some interesting facts from an op-ed in today's Oregonian on biofuels:
What about biofuels as a way to reduce our dependence on fossil fuels? Biofuel production, especially corn ethanol, is energy intensive. Even if we used the entire U.S. corn crop of 12 billion bushels to make ethanol, the net contribution would amount to just over one-half of 1 percent of our fossil fuel energy consumption. And even that number is highly optimistic.What about cost effectiveness? The cost of using the nation's entire corn crop for ethanol would be about $7.6 billion. By comparison, studies estimate that raising the gas tax or tightening fuel economy standards could achieve 10 times as much in fossil fuel reductions for the same cost.

Pledging to “move toward a low-carbon society,” leaders of the world’s richest nations endorsed Tuesday the idea of cutting greenhouse gas emissions in half by 2050, but did not specify whether the starting point would be current levels or 1990 levels, and refused to set a short-term target for reducing the gases that scientists agree are warming the planet.Is it possible for a civilization to commit suicide?

Lenny Susskind's lectures are the kind of thing that television should have been all along. Thank god for the Web. You can watch and almost feel that you're in the audience.

The Riemann Hypothesis, now 149 years old, is probably the most famous unsolved problem in mathematics, since Fermat's Last Theorem has been proven. (Had the RH appeared on a roll of toilet paper or something, with a flippant remark or a curse word beside it, it might well have eclipsed FLT in fame.)
The author is Xian-Jin Li of Brigham Young University, a mathematician amidst a group of people who have been making a serious push to solve the RH for several years. Li posted his proof on Tuesday at 12:43 pm MDT. Peter Woit blogged about it yesterday, and yesterday evening at 7:28 pm MDT Terry Tao of UCLA claimed to have found a problem in the proof.
But a new version of the proof (v3) was posted by Li last night at 8:44 pm MDT, so perhaps the story is not yet finished.
Li's proof is not long and does not look overly complex (of course, I'm not an expert in analytic number theory) -- you'd almost think you could understand it. There are even some integrals, which I did not realize were still allowed in modern mathematics.
Yang said there are two kinds of mathematical papers, the kind you can't understand past the first page and the kind you can't understand past the first sentence. Wouldn't it be amazing if the proof of the RH was the former!
PS: There is no shortage of purported proofs of the RH....

What a disincentive towards entrepreneuralism.
The whole system is literally breaking down before our very eyes. It is amazing to me how passive politicians (at all levels) are about this. My own state representatives to whom I've written could hardly seem to care less.
