New research suggests that huge domes of carbon dioxide hover over urban areas, which is prompting some scientists and policymakers to stress the importance of cities as the frontlines of the war on greenhouse gas emissions.
"Mark Jacobson, professor of civil and environmental engineering and director of the Atmosphere/Energy Program at Stanford, has been vocal about the need for a complete clean-energy transformation. This week, with the political world consumed by health care, his work offers a reminder that carbon pollution is a serious health problem. It makes traditional air pollution-such as particulates and ozone-more harmful, so it poses particular threats to the places with the worst air pollution-cities."
