Ozone pollution in India is damaging millions of tons of the country’s major crops, according to a new study by an international team of researchers. The pollution caused losses of more than $1 billion in a single year, destroying enough food to feed an estimated 94 million people.

An estimated 40 percent of the world's waste is burned in unregulated fires, emitting pollutants that can harm human health and the environment.

Researchers at NCAR and partner organizations this summer are using aircraft, ground-based sensors, computer models, and other tools to track the origins of summertime ozone, a significant health threat.

California will likely experience more large fires in forested areas this century because of rising temperatures and changes in precipitation along with development patterns, new research finds. The blazes could increase some types of fire-generated air pollution by more than half.

A new grant will help researchers measure pollution from open-fire cooking and better understand a problem that kills millions of women and children in developing countries.
