For the first time ever it appears that a red alert for air pollution has been issued for Beijing. More details on the color-coded alert scale and its implications can be found here. The high-resolution satellite image of the pollution, which was taken this morning and shows the pollution stretching far beyond Beijing, is almost too much to believe.
