Global Air Pollution, From Above

neutron_p writes "Based on satellite observations, the high-resolution global atmospheric map of nitrogen dioxide pollution makes clear just how human activities impact air quality. I'm a bit surprised not to see that many red blobs above US and the strange one is on the east of Russia."

    Take note everyone, the biggest red blob is over China (insert communist jokes here). For all the whining and complaining about how the US should have joined the Kyoto accord, it's very easy to see that China is the #1 offender, and that Europe is not doing so hot itself. What good would Kyoto have done if it exempted the country who needs it most?

    That being said, China is still developing. Pollution should be a big concern for them, but it's an unfortunate fact of life for now. As their technology improves, the pollution levels should drop. With one caveat, that is:

    Many modernized countries have sent their manufacturing to China. Thus placing restrictions on countries to reduce their emissions will do little good when we've already sent the real pollution over there. I'm not sure how we can respond to the situation, but it's important to pay attention to it.

    The blob over Canada is actually a bit surprising, but I'm guessing that's related to the earlier article on the odd increases in pollution levels. I do have a thought on why North America sees less pollution than Europe, however. Since the North America has a massive amount of farmland and forest land, a good deal of the pollution is sapped up by these massive carbon sinks. This doesn't actually impact NO2 levels, but it does explain some of the pollution reduction.

    FWIW, it seems that NO2 is primary produced by cars. Moving to the hydrogen vehicles of the future may help stop almost all NO2 production.

      I'm a bit confused by the angle of your post. It seems to me that you would want China to reduce its emmissions too. However according to wikipedia China emits 2.3 tons per capita of CO2 while the U.S. 20.1 tons per capita (Europe at 8.5 tons per capita.) and isn't this the way to look at emissions? I believe that there is a base energy requirement to support one person and that for most of the world this - sadly - means burning fossil fuels. (At least at present time.) Thus shouldn't China really be allowed to release 5 times (gross product) as much as the U.S?

      Now there aren't AFAIK any restrictions on China or other developing countries, but China has ratified the agreement and when they really step up as an industrialized country they will have restrictions imposed thus it is in their interest to stay within the future requirements.

      Had there been placed restrictions on China or other developing countries they probably never would have signed the agreement because it might have inhibited their growth. (Now what is the real reason the U.S. isn't signing?)

      Furthermore I don't think the true objective is reduced emissions, we're far to spoiled to let that happen. The point is getting a situation under control before it gets out of hand.

  2. I'm not suprised, because I have a clue by jmorris42 · · Score: 5, Insightful

    The submitter is suprised, but I'm not. Wealthy nations can AFFORD the luxury of enviromentalism, unlike poor ones like the former Soviet block and the third world. The solution is obvious, encourage more nations to become wealthy by helping them become free.

    No serious student of current events can escape the reality that political freedom and economic prosperity are linked. The old soviet empire attempted to foster economic openness to gain it's productivity benefits while keeping political freedom in the hands of the Party. They failed. China is making the same attempt and the signs are they are also going to fail. Freedom is the natural state of affairs and you can't supress it in one sphere while keeping it in the others.

    Rising standards of living solve most of the pressing problems facing the world today. Birth rates are lowest in the free/wealthy nations and highest in the poor/oppressed ones. Wealthy/Free nations don't tend to make war on each other. Wealthy nations don't tend to produce terrorists either.

  6. One step China has taken - by Tristan7 · · Score: 5, Informative

    China has prohibitted the burning of wood by anybody, and has undertaken a massive reforestation project across the nation. Wood fires produce incredible amounts of pollutants, especially open cooking fires. By reforesting wherever they can, various types of pollution will be reduced. Of course, all this takes time, but it is a good step.
