New U.S. National Aeronautics and Space Administration (NASA) satellite images show conclusively that huge reductions of air pollution have occurred across the U.S. over the past decade. In particular, air pollution of the greenhouse gas nitrogen has been measured by the Ozone Monitoring Instrument (OMI) on NASA’s Aura satellite for the past 10 years. This ozone-forming nitrogen and its combustion cohort carbon dioxide (CO2) constitute about 60% of all climate related greenhouse gases, and are released from burning fossil fuels and vehicle exhaust emissions – see EPA pie chart above.
During the decade of OMI monitoring, levels of nitrogen dioxide in the atmosphere over major cities across the U.S. declined by 20 to 40 percent. Nitrogen dioxide is one of the six common pollutants regulated by the U.S. Environmental Protection Agency (EPA) to protect human health and climate change. (Science World Report, June 27, 2014)
The surprising reductions in these air pollutants is attributed to the extensive and costly U.S. system of environmental regulations developed over the last 40 years – costing about 5% of U.S. gross domestic product (GDP) annually. Note that the cleaner air conditions have come without Pres. Obama’s incessant and partisan calls for even more costly climate controls in his gratuitous “war on carbon.”
It appears that the massive system of U.S. air pollution regulations is sufficient to continue to protect our health and climate without more political pandering to the green lobby that can only rob us of prosperity and kill jobs in their perverse narcissism of saving the planet.
