    How Well is the World Protecting Ecosystems and Human Health?

    The new global environmental report card is out. The 2016 Environmental Performance Index graded 180 countries on how well they are protecting human health and their ecosystems. While the world is making progress in some areas, it is seriously falling behind in others.

    The Changing Face of Air Quality

    Looking at regional differences in PM2.5 concentrations gives us a sense of the changing face of air quality throughout the world.

  • Bad Ozone Days in Western U.S. Linked to Pacific Weather

    Bad Ozone Days in Western U.S. Linked to Pacific Weather

    A new study shows that ozone pollution in the western United States can be increased by La Niña, a natural weather cycle at the surface of the Pacific Ocean. The finding is the first to show that the La Nina-El Nino cycles directly affects pollution.

  • Bottom Up or Top Down? Another Way to Look at an Air Quality Problem

    Bottom Up or Top Down? Another Way to Look at an Air Quality Problem

    While not all countries have the financial wherewithal and capacity to deploy ground-based instruments for air-quality monitoring, and for some countries monitoring information is not available to the public, for example, through health advisories, another way exists to assess air pollution levels: through satellites.
