More than half of the Colorado River's water is used to grow crops, primarily livestock feed, a new study finds. The river and its users are facing tough decisions as the climate warms.

Scientists looked at trees to better understand the interplay between temperatures and droughts in the Western U.S. Human-caused climate change is exacerbating both.
