Human impacts of global air quality 'aren't random': NASA

How have humans impacted on global air quality? Changes in patterns over the last decade "aren't random", NASA says.

This NASA map tells the unsettling story.

Air pollution patterns around the world from 2005 to 2014 have been tracked in a new study, using global satellite maps of air quality indicators to help "quantify energy usage, environmental policy and civil unrest".

NASA looked at levels of nitrogen dioxide — a common emission from cars, power plants and industrial activity that can quickly transform into ground-level ozone, a major respiratory pollutant in urban smog.
