Watching China Turn Off the Pollution 427

NewbieV points out coverage of the effort to assess Beijing's air pollution control efforts. Quote from one of the investigators: "This will be a very interesting experiment that can never happen again." Here's the main project scientist's site on the monitoring effort, and Newsweek coverage that brings out a paradoxical effect of reducing pollution on global warming. "Unmanned aerial vehicles are measuring emissions of soot and other forms of black carbon. The instruments are observing pollution transport patterns as Beijing enacts its 'great shutdown' for the Summer Olympic Games. Chinese officials have compelled reductions in industrial activity by as much as 30 percent and cuts in automobile use by half to safeguard the health of competing athletes immediately before and during the games."

    Carbon Dioxide (and other greenhouse gases) increase heat retention. Soot (and other opaque particulate matter) reflect heat before it reaches us. The trick is determining the effect of each in isolation. The temporary reduction in soot emissions in Beijing gives us a chance to see the effect of soot in isolation (or close to it).

    This isn't exactly new ground (we've previously observed the effect of increased particulate matter in the wake of large volcanic eruptions), but it's one of the few times we see it in reverse, triggered by human activity.

    Why is it, when there are more important issues, this ONE, probably a lesser issue, gets all the "controversy" air-time?

    Some reported facts and anecdotes:

    As told to velonews, air pollution builds-up because Bejing sits on the edge of the Gobi desert. A good rain is required to clear the air that's trapped in Bejing. http://www.velonews.com/article/81199 [velonews.com]

    As a former competitive cyclist living in Los Angeles, I can tell you from experience, you feel the pollution later, not really during the event.

    What *would* affect most outdoor performances more than pollution is the heat/humidity combination.

    Finally, the last olympics had major heat issues for road cyclists, so each location has issues. Smog is not a major one for Bejing.

    "It doesn't matter if global warming is true or not. We all want cleaner air."

    Except that "fighting global warming" isn't about cleaner air. It is about reducing "greenhouse gases", primarily CO2, which is an essential part of the atmosphere. So, it does matter if "global warming" is true, because people like Al Gore are asking us to cripple our economies to reduce CO2 emissions, which are only a problem if global warming is a problem.
    Which is a question that I rarely seen discussed. If Global Warming is true, is it really a problem?

    Chinese officials to citizens: We can move heaven and earth when we deem it sufficiently important; foreigners will enjoy proper breathing conditions. Once they are gone, you'll go back to sucking down the equivalent of a cigarette drag every time you breathe outdoors. STFU, coolies, and get back to work.

    Everybody is talking about how this will be the Chinese century, rah-rah, all is grand. History doesn't always go along with the popular consensus. The communist revolution was supposed to occur in advanced, capitalist countries, not a semi-feudal backwards backwater like Imperial Russia. Everyone was convinced the Shah's Iran was a model of western influence in the region and a shining bulwark against religious radicals. Hardly anybody saw the Iranian revolution coming.

    I'm not saying it will go one way or the other, I'm just proposing a scenario on how China could fail in a couple of broad brushstrokes.

    1. Eroding faith in government. We already saw how bad their construction was after that recent quake. 20 year old buildings stood up to the shaking, more recent buildings fell down. Government regulation and enforcement has failed.

    2. Shitty infrastructure. A lot of reports talk about how the Chinese are building a bunch of stuff but the quality has been poor. This is not infrastructure that will last for decades, this is just slapping stuff together as quickly as possible, Haliburton style. We already know Three Gorges Dam has a lot of problems, what happens when it fails during a quake? Go back to point 1, eroding faith in government.

    3. The pollution is freaking out of control. What kind of collapses and failures environmentally can they look forward to? The Gobi is expanding rapidly. What happens if they have famine?

    4. Economics. Right now they are holding an incredible amount of American debt but to what end? Is this an economic cudgel to use against us? What if they misjudge and the weapon turns out to do them more harm than us? If the US defaults on the loan, what next? Who are they going to sell their cheap shit to? Are their domestic markets ready to create demand and wealth?

    5. Disproportionate share of prosperity. The oligarchs are making out fine, what about the rest of the people? Will class resentment grow too powerful?

    6. Population time bomb. One Child per Family means there's a lot of boys and not many girls to go around. What are they going to do for wives when they grow up? And what of families who have lost their only sons in disasters like the quake. The Chinese put a huge premium on family, carrying on the line, etc. Could there be massive popular resentment against these policies when such disasters wipe out entire families such as we've seen?

    It seems like the current Chinese leadership has learned from the errors of their predecessors -- isolationist thinking in a violent world makes China a conquered country. They're now going to be actively engaged on the world stage. It will remain conflict to be sure, but how much will be diplomatic, how much economic, and will military be resorted to when the other two have failed? Will China get itself involved in wars it cannot win? Could a major loss see the fall of the party? What would the successor states be like? Would we see a return to the warring states period?

    Lots and lots of questions. I just think the whole "This is China's century" narrative is only one of several possible outcomes.

    Why is it, when there are more important issues, this ONE, probably a lesser issue, gets all the "controversy" air-time?

    I, for one, would like to hear a little more coverage of how the Chinese got all of their 16 year old female gymnasts to all look between the ages of 8 and 12. We know they're all 16, though, because, according to the broadcast, their passports confirm it. What's the point of the new "16 and over" rule if the only way they check ages is by looking at government issued passports? Surely the government would have no reason to lie! Sort of like the East German women that were all drug-free in the '70s and '80s, despite the adams apples and mustaches.

    The gymnastics events have always been sort of a joke as far as fairness is concerned, but the new incomprehensible scoring system and the apparently barely enforced 16 and over rule seems to have made things worse, not better.

    The BBC is measuring pollution themselves [bbc.co.uk], much to the annoyance of the Chinese government. August 10 was a really bad day. August 11, not so bad.

    The equestrian events are in Hong Kong, which also has high pollution, but the drastic control measures being used in Beijing aren't being applied to Hong Kong. That's a small-scale competition. Hong Kong's racing fans think dressage is boring, and more than half of the 10,000 spectators walked out yesterday.

    It would seem to me, not that I understand this being a layman, but, it would seem, that the effect of the year of burning oil fires in Kuwait after Sadaam's people torched them at the end of Gulf 1 would have been the single greatest contributor to global warming, carbon footprint, or whatever the term du jours is. How does Bejing rank compared to that massive injection?

    "Once they are gone, you'll go back to sucking down the equivalent of a cigarette drag every time you breathe outdoors"

    that reminds me, there was a new york city marathon runner, never smoked, and when they died their lungs were as black as a life long smoker of 60 years, a 3 pack a day smoker's lungs.

    even with 'tough' anti pollution laws, you can still get three packs a day worth of crud in your lungs just from running outdoors in a large city.

    If Global Warming is true, is it really a problem?

    Well if you are just looking for the economic consequences of global warming the Stern review must be the most well known work. Nicholas Stern was the chief economist of the World Bank, 2000-2003. Here is the Wikipedia summery [wikipedia.org]:

    Although not the first economic report on global warming, it is significant as the largest and most widely known and discussed report of its kind.

    Its main conclusions are that one percent of global gross domestic product (GDP) per annum is required to be invested in order to avoid the worst effects of climate change, and that failure to do so could risk global GDP being up to twenty percent lower than it otherwise might be. Sternâ(TM)s report suggests that climate change threatens to be the greatest and widest-ranging market failure ever seen, and it provides prescriptions including environmental taxes to minimize the economic and social disruptions. He states, "our actions over the coming few decades could create risks of major disruption to economic and social activity, later in this century and in the next, on a scale similar to those associated with the great wars and the economic depression of the first half of the 20th century." In June 2008 Stern increased the estimate to 2% of GNP to account for faster than expected climate change.

    The Stern Review has been criticized by some economists, saying that Stern did not consider costs past 2200, that he used an incorrect discount rate in his calculations, and that stopping or significantly slowing climate change will require deep emission cuts everywhere. Other economists have supported Stern's approach, or argued that Stern's conclusions are reasonable, even if the method by which he reached them is open to criticism.

    Smog is not a major one for Bejing.

    Tell that to anyone not living in that cesspool.

    All I had to do was travel to Toronto for few days and I was feeling scratchy throat and "like something was coating my lungs". That was NOT on a smog alert days which I think is when their particulate matter is over 50 or something. Well, Beijing has PM10 readings of about 4x that. 4x what in Toronto is a smog alert.

    Sorry, but I would not go there to compete about anything. And if you live there and think it is not bad, go somewhere without smog, like central Australia or central canada (eg. Manitoba) or mid-west US or someplace like that. Then I *dare* go back to Beijing and tell me that it is not too bad.

    I know what I speak off. I used to live in Poland with their coal fired house heating. After snow fell, it become coated with soot after a few hours (gray coating). Frankly, I never knew there is such a thing as *clean snow* until I came to Canada. Here, snow is as clean on the day it fell as it is 5 months later when it melts.

    People living in cesspools like that have NO IDEA the shit they are living in. You have to GET OUT and live someplace else for a while, then go back and compare.

    The only thing I can compare this too is like getting your first pair of glasses. You think you can still see fine, but your eyesight is crappy and foggy. Then you get your eyeglasses and you can't believe how sharp everything is! Same thing with pollution. It sneaks up on you until you can't breath anymore. And then you end up complaining that it must be the food or something unrelated.

    Wake up people. Wake up and put on your first glasses to see the crap you area breathing!

    The sixty million surplus boys will give their rifle female names. If you live in Siberia, get out now. China has an insatiable appetite for natural resources. They share a 4000 mile border with a country with oodles of said natural resources, and a population with the lowest fertility rate on Earth.

    A generation from now, China will annex all of Russia east of the Urals.

    Russia has nukes and will continue to maintain them for the foreseeable future. It took a while for me to wrap my head around this as a kid since it seemed like China and the USSR should be buddy-buddy since they're both communist. It was hard to understand that the USSR looked at China with as much suspicion as they looked at NATO. Many nuclear scenarios for WWIII saw the Soviets shooting both east and west.

    The Soviet bluff was that they believed they could survive a nuclear war. Now I say bluff, I think they were trying to scare us. But hell, maybe they really did think it would be winnable. We already know the Chinese philosophy concerning nuclear war: "So we lose a few million." (This offhand comment was made during the Korean War when MacArthur was demanding we go nuclear.) Honestly, I think the Chinese government would probably see a nuclear attack as doing them a favor. I do not relish the thought of a general war with China. I've got images of Japanese banzai charges but hundreds of times larger.

    We're looking at a future of scarcity and resource wars. The only way to truly avoid any number of uncomfortable scenarios is to grow the pie, provide more resources or use existing resources more efficiently so that everyone can have a seat at the table. Unfortunately, human nature says "Why should I work to double the milkshake supply when I can drink yours instead?" And there's Cheney with a straw.

    It is about reducing "greenhouse gases", primarily CO2, which is an essential part of the atmosphere.

    The incorrect implication being that we risk reducing CO2 too much, as it is 'essential.' It is unlikely that we even *could* do this, and we are certainly not at risk of doing so.

    So, it does matter if "global warming" is true, because people like Al Gore are asking us to cripple our economies to reduce CO2 emissions, which are only a problem if global warming is a problem.

    The cripple our economies claim is so non-sensical, I wonder if people actually believe it. Reducing carbon emissions != economic disaster. It will mean an adjustment that more accurately prices the use of carbon-heavy items (fossil fuels in particular) by accounting for the huge negative externalities they cause. So yes, oil will get more expensive, but cleaner technology will get cheaper. Capital investment will funnel towards greener technology at the cost of high-carbon-output technology. Rather than there being tons of profit in, say, mining coal, there will profit in, say, developing high efficiency refrigeration or higher temperature superconductors.

    The crippling-the-economy baloney assumes that our economy can not change and adapt to a different set of value models, something that is just clearly not true.

    If Global Warming is true, is it really a problem?

    If you care to believe science, climate change is true. If you think adapting 6 billion people to new shorelines, climates, and weather patterns is not a problem, then no..it might not be such a big deal. Seems to me, though, it probably will be.

    I went on a tour of the major cities (and some minor ones) back when they were awarded the Olympics. Massive slum-clearing and beautification projects were underway, partly for social reasons due to Olympic visitors, but the big reason was to increase the green space in Beijing. All of the highway bridges were installed with tree planters and trees were being grown in the outer suburbs and trucked in to the city in the hopes it would reduce pollution and alleviate the windy, dusty conditions that are, evidently, a normal part of Beijing life.

    Beijing does not really have a smog problem because smog requires humidity. This region suffers from excessively dry and dusty air in almost every season. We felt it almost immediately when we deplaned for the Beijing leg of our trip. It is an unfortunate ecology event that Beijing is not only dry and dusty but it also suffers from regular sand-storm-like weather events, though they don't really refer to them as sand-storms in Beijing. Some of the popular culture regrets the capital was moved to dry, arid Beijing when they fell it should have remained in temperate Nanjing, the "south capital."

    If you'd like to replicate this experiment in a NASA climate simulation yourself, the EdGCM [columbia.edu] project has wrapped a NASA global climate model (GCM) in a GUI (OS X and Win). You can add CO2 or turn the sun down by a few percent all with a checkbox and a slider. Supercomputers and advanced FORTRAN programmers are no longer necessary to run your own GCM.

    Within the last year, I visited Asia including Taiwan (*cough* sorry, that's "Chinese Taipei"), Hong Kong, Shenzhen, and Shanghai -- although not Beijing. Throughout my travels I saw a number of locals wearing masks in different places: bicyclist or motorcyclists, pedestrians, people in airports and on planes.

    High thin clouds have a different effect from low thick clouds with respect to surface temperature.

    High thin clouds reflect/reradiate more infrared energy downwards while low thick clouds reflect more incoming visible band radiation back to space. The infrared band energy radiated by the surface is heading out to space to balance the incoming (from the sun) higher frequency radiation. The result is that high clouds may warm the surface while low clouds cool it.

    Neat eh?

    I think the biggest opportunity that could be had here, besides the science, is that China's and specifically Beijing's residents will get to see what their city is like without much pollution. I hope that they come to the conclusion that they LIKE not having smog and pollution. There is the possibility, that the Chinese will demand that they want less pollution in their cities, and are willing to do what it takes to clean up their power plants, cars, and factories to do it. If only they we could do this once a year for all big countries. India, Brazil, Russia, China, the U.S., etc... We could get people really behind making positive changes.

    So what we found was a bunch of stuff that was kept secret but could be COMPLETELY INNOCENT (minus planes/missile engines), but could also possibly be used to bring up a WMD program full-scale in a month or so (i.e.: Very fast). Depending on the logic you apply, we found nothing or everything. Both sides have an argument.

    Except the Bush administration simply stated (and reiterated hundreds of times over) that there were WMD's in Iraq. Not "there might be" or "there could be resources that bring up a full-scale WMD program within a month."

    When this discussion comes up, I think a lot of people are just upset that they were lied to. The Bush administration definitely tried their best to make it seem like Saddam had stockpiles of nuclear weapons. Excluding the "Oops, we made an honest mistake" (easiest excuse to use when you get caught lying) argument, I really don't think both sides have an argument on this topic.

    Today, I heard a very interesting comment on an early-morning business/investment radio show that I listen to:

    One of the hosts was talking about how the Chinese stock market has gone South lately because of this "Great Shutdown", but he was trying to give his listeners encouragement by telling them that as soon as the Olympics are over, China will go back to their polluting ways and then all will be well for the investment community that depends on China in so many ways.

    It was a very clear window into a world where the business community absolutely prays for the bad things to happen to most of us, in order for the very very few to get rich. Honestly, there was a pause in the host's spiel during which it almost seemed as if he realized what he was saying, and the moral implications of wishing environmental disaster on a billion people so that he and his friends can offset their sub-prime losses.

    It made me realize that there are worse things than a severe downturn in the stock market. It might even do some good, except for the fact that so many of us have been suckered into putting our retirement savings into that fool's game. Can you imagine what might have happened if we'd listened to Bush and McCain and had privatized Social Security?

    Tell you what: China's economy is going to come on strong in the next few decades, and the US is thinking it's going to go along for the ride. The only problem is, once the Chinese figure out what this "economic boom" really means, they are going to be really really pissed.

    My wife's family lives on a rice paddy in rural Japan and the air looks exactly the same as it does in Beijing all summer long.

    (I've never been to Beijing in the summer, but I was in Beijing the week before the IOC got there and what I saw and breathed made Los Angeles and Tokyo look like pristine rural parks).

    It varies from place to place. Tokyo and the Kanto plains is quite polluted even in the rice paddies. So is Osaka/Kobe and Kansai. Higher up is clear.

    You do not see the air in the Philippines, usually even in Manila despite the humidity.

    The point is when the humidity level is that high, you can't tell visually how polluted a city is.

    From TFA:

    Data-gathering flights... will originate at the South Korean island of Cheju, located ... in the projected path of pollution plumes originating in various cities in China including the capital.

    But take one look at the map [ucsd.edu] in the article and ... hey, wait a minute... Jeju/Cheju Island [wikipedia.org] is located right smack in the middle of that blue blob in the lower middle of the photo!! And since the caption says "Areas in red depict the dimensions of the main aerosol mass emanating from Beijing", that means Jeju is exactly the WRONG place to gather data, since it's out of the aerosol stream.

    This is a factual inconsistency in the article, as the map and the text contradict each other. Granted, most Americans couldn't find Jeju on the map, but that's still no excuse for poor attention to geography on the part of the article writers.

    Which makes one wonder why these measurements aren't being taken in China. Oh wait, but of course they are. It's just that the measurements are being done by Chinese scientists ... and the fact that they aren't working in cooperation with the American scientists is just further evidence that there is a real information Great Wall between these countries...

    From our friends at Wikipedia on the Greenland Ice Cap (not sea ice): If the entire 2.85 million km^3 of ice were to melt, it would lead to a global sea level rise of 7.2 m (23.6 ft)[2]. This would inundate most coastal cities in the world and remove several small island countries from the face of Earth, since island nations such as Tuvalu and Maldives have a maximum altitude below or just above this number.
