Joint Program researchers call for ongoing investigation of, stricter controls on U.S. cross-state air pollution (The Conversation) (Republished in Salon)
Scientists estimate that each year in the U.S., outdoor air pollution shortens the lives of about 100,000 people by one to two decades.
As it turns out, much of this pollution originates not in a person’s own neighborhood, but up to hundreds or even thousands of miles away in neighboring...

The Science
Statistical emulators of global gridded crop models are designed to provide a far less computationally intensive way to assess the impact of climate change on crop yields. This study advances statistical emulators to provide an accessible tool to assess the impact of climate...
