NO₂ Polution from Space:

World's pollution hotspots revealed from space

Yup...looks like Switzerland is in trouble. Massive cloud all along the Italian border.

/sarcasm.

Seriously, China has he biggest aggregate problem and WE are the bad guys??

It is bs.

Notice how the biggest clouds of pollution in the US hang over the Blue states - coincidence?? I think not.

[Holicheese]

did you notice that the US pollution hot spots look exactly like the election map of Kerry counties?

That NO2 Pollution from Space picture you posted shows three elevated regions on the Australian continent where I live. Aside from the East Coast being the most populated area, I notice that the 'spots' shown are also where we generate power from coal.
In the case of China, (which buys much coal from other countries and also has numerous coal mines) I noticed in a recent documentary on China that the majority of households still use coal for cooking and heating, much as europe did in the early 1900's.
The map also shows Austria which is heavily polluted also due to coal fired industry such as steelworks. I am not a scientist, but I am inclined to believe that atmospheric pollution might be the direct result of heavy dependence on the use of coal.
The area around the Great Lakes in North America - just how much coal is being used there, I wonder?
