The climate of the southwestern U.S. could be a lot drier by 2100. The climate of the northeastern U.S. could be a lot wetter.

"These visualizations communicate a picture of the impacts of climate change in a way that words do not," says Allison Leidner, Ph.D., a scientist who coordinates NASA's involvement in the National Climate Assessment "When I look at the scenarios for future temperature and precipitation, I really see how dramatically our nation's climate could change."

New visualizations of computer model projections show how precipitation patterns could change across the U.S. in the coming decades under two different carbon dioxide emissions scenarios.

The date seen in the bottom-right corner is the mid-point of the 30-year average being shown. To learn more about the National Climate Assessment, due out in 2014, visit here.
