2 Charts That Put the Chinese Pollution Crisis in Perspective

No one now alive has experienced anything similar in North America or Europe, except in the middle of a forest fire or a volcanic eruption.

Everyone "knows" that China is badly polluted. I've written over the years, and still believe, that environmental sustainability in all forms is China's biggest emergency, in every sense: for its people, for its government, for its effect on the world. And yes, I understand that the same is true for modern industrialized life in general. But China is an extreme case, and an extremely important one because of its scale.

Here are two simple charts, neither of them brand-new but both easily comprehensible, that help dramatize how different the situation is there. The first, by Steven Andrews for China Dialogue via ChinaFile, compares official Chinese classifications of "good" air conditions with those in Europe or North America. 

Here is the point of this graphic: The green and yellow zones in the left-hand column, showing official Chinese government classifications, are for "good" or "OK" air—while those same readings would be in the danger zone by U.S. or European standards. When you're living in China, it's impossible not to adjust your standards either to ignore how dire the circumstances are, so you can get on with life, or to think that any day when you can see across the street is "pretty good."

The scale for all countries stops at 250 (micrograms per cubic meter). Everyone who has spent time in Beijing or other bad-air cities knows what it is like with readings of 500 or above. Even Shanghai had a 600+ "airpocalypse" this past winter. No one now alive has experienced anything comparable in North America or Europe, except in the middle of a forest fire or a volcanic eruption.

Here's the other chart, comparing the 10 most-polluted Chinese cities with the 10 in America. It is from The Washington Post a few weeks ago:

The U.S. readings on this chart show something about challenges in the Central Valley of California, which is where six of the seven most-polluted cities are. (And the other is Los Angeles.) More on that shortly, in our American Futures series. But the scale difference of Chinese pollution is sobering. Even the worst American cities would be in the tip-top most excellent bracket in the chart at the top.

More sobering still: Air pollution, while the most visible (literally), is not the most serious of China's environmental problems. Water pollution, and water shortage, are worse.
