China’s size and the magnitude of its industrial activities do indeed cause it to generate large amounts of air pollution, but every country contributes to the “world’s pollution.”
The air travels across the Pacific Ocean from China to the West Coast of the United States in about five days. Scientists here at Scripps Institution of Oceanography, UC San Diego, and elsewhere have been able to observe the movement of that air and the pollution it carries from flights aboard research aircraft, at stations on the ground and by using satellite imagery. There is evidence that particulate pollution from Asia affects precipitation in California and hastens the melt of snow in the Sierra Nevada because the pollutants darken the snow, which then absorbs more solar energy than does clean snow.
