NASA Releases Orbital Photos of Beijing's Air Pollution
skade88 writes "This story should remind us all that air pollution controls are not just about addressing global warming. They also help us have cleaner air and fewer health problems resulting from smog and haze. Starting earlier this month, Beijing, China started having worse than normal air pollution issues. On January 14, 2013 the U.S. embassy's air pollution sensors in Beijing found the density of the most dangerous small air particles, PM 2.5, at 291 micrograms per cubic meter of air. The World Health Organization's guidelines for air pollution state that PM 2.5 above 25 micrograms per cubic meter of air is dangerous to a person's health. To put the problem into perspective, NASA has released two orbital photos of Beijing showing before-and-during images of the air pollution. The photo from January 4 shows parts of Beijing still visible from space. The photo from January 14 shows nothing but a huge, thick cloud of haze with no buildings visible."
In a rather Bender-esque way, the literal translation from Mandarin for its populi (the PM2.5 breathers) is "Meat vacuums", and not in a good way I might add.

I remember from my youth that's what LA used to look like in the 70s. Those were back in the days we had to walk 5 miles to school each day in the dirty gray snow. Course once we realized it was not actually snow, but several inches of dusty sooty crud, we stopped wearing our parkas.
Go go gadget smokescreen!
Smog in some US cities was bad way back in the '70's but nowhere near what it's like in Beijing this month. When you call US environmental conditions "woeful" attached to an article about the pollution going on in China, it really lets your ignorance shine. The US environment isn't perfect, but yes, it is vastly superior.
on days like these, you can see it, smell it and... taste it.
PM 2.5 stands for particulate matter smaller than 2.5 micrometers.
According to the Wikipedia particles of this size cause a broad array of terrible consequences in the body.
Perhaps Americans should consider improving their own woeful environmental standards before throwing stones at other countries, as good as it may make them feel.
Aaaannndddd there it is.
I propose a new 'law', similar to Godwin and others.
Any discussion pointing out a countries problems will include, within the first 20 comments, a reference to how the USA is worse with regard to that particular problem.
We could call it the 'Dumbfuck Law'.
Nice try, but no. Beijing isn't that big of a manufacturing center (relatively speaking) - most of the pollution comes from IC engines and (especially important this time of year) the decentralized system of coal powered hot water plants that provides most of the cities heating.
US standards are PM2.5 of 15ppm annually and 35ppm over 24 hour average, and regions are considered "non-compliant" and have to take corrective action if they don't meet that. China hit 800ppm on 1/12/13. And you know who's fault that is? China's. Don't even pretend their government is somehow owned by US interests. It's getting closer to the other way around.
So, yes, the US is a HELL of a lot better environmentally. Please do the tiny bit of research it takes before saying stupid shit like that.
China has replaced their "One Child" program of population control with a new "One Lung" policy.If you can't get rid of the babies, at least you can weed out the weak, the old, and the heavy breathers.

Table-ized A.I.
The EPA has actually made huge strides in the U.S. To the point that big cities which used to have smog constantly and you could see the air are now clear.
So, naturally, Republicans want to end the EPA. Can't let the hippies win!
I live ze unknown. I love ze unknown. I am ze unknown.
Relatively speaking?
Have you been outside the 5th ring road? Ive seen factories the likes id never seen in my life. Sprawls of smokestacks just chugging away. Not to mention the fact that DAMN NEAR EVERY RESTAURANT AND MANY HOMES STILL USE COAL.
During the Olympics in 08 they had all the factories shut down for a month prior and seeded the clouds for a week to wash the city and air. Worked wonderfully.
Cars are a problem - and a growing one to say the least - but dont be too quick to discount the manufacturing and a city of 16 million still using coal.

You really need to learn about what exactly bankruptcy entails.
Iceland went bankrupt a couple of years ago. The effects make a good case study.
We send manufacturing over there because it's cheaper. A major reason why it's cheaper is the lack of regulations. No need for smoke filters, no worries about dumping waste in waters. Then we take pictures and post it on the internet. And we feel good about our yard and complain about theirs.
