Description: |
Dust storms on the scale of Black Sunday of the 1930s Dust Bowl may be a distant memory, but the U.S. Southwest and Great Plains still experience episodes of blowing dust that snarl transportation and threaten public health. These storms also spell trouble for the snowpack and water supply in the Rocky Mountains. Preliminary modeling research found human-caused global warming is likely to have widely diverging impacts on U.S. dust storms, with significant increases in the Southwest and Southern Plains in warm months, but decreases year round in the Northern Plains.
