CO2 is not smog. Despite the photographs selected to illustrate MSM global warming propaganda, Beijing’s air quality problems are caused by NOx, SOx, volatile organic compound, and particulate matter emissions, not CO2.
There’s a curious fact about Beijing air quality. By focusing on CO2 emissions, environmentalists make it more difficult to reduce real air pollution; that is, the type of air pollution that make the air that Beijing-ren actually breath so foul. Air pollution control equipment takes energy to operate and reduces the efficiency of generating electricity.
