New NASA images highlight U.S. air quality improvement

As something of a balance against the environmental issues we’ve been discussing, here is an encouraging sign of progress: New NASA images highlight U.S. air quality improvement — ScienceDaily.

Satellite data show that New York City has seen a 32 percent decrease in nitrogen dioxide between the 2005-2007 (left) and 2009-2011 (right) periods. The city tops the charts in terms of U.S. population, which usually means more air pollution. Even here, however, the air is on the mend. Credit: NASA Goddard’s Scientific Visualization Studio/T.

Anyone living in a major U.S. city for the past decade may have noticed a change in the air. The change is apparent in new NASA satellite images unveiled this week that demonstrate the reduction of air pollution across the country.

Of course, we shouldn’t take this as an excuse to be complacent, but it’s nice to see that progress is being made on some fronts.
