SUSAN DONALDSON JAMES, ABC NEWS - A study co-written by researchers at
Columbia and Princeton universities confirms that long-term drought is
already under way in the American Southwest - one that may last the rest
of this century, if not longer. These scientists attribute this new
climatology in one of the fastest-growing regions of the United States
to global warming.
Senior researcher and geophysicist Richard Seager . . . and his
colleagues at Lamont-Doherty, and at the National Oceanic and
Atmospheric Administration's Geophysical Fluid Dynamics Lab at Princeton
looked at 19 different computerized climate models from around the
world. Similar to those used for weather forecasting, the models dated
back to 1860 and projected to 2100. The models showed a marked increase
in arid climate beginning around now and worsening through the current
century. . .
Meteorologists report that summer temperatures are running 10 to 15
degrees above normal in states like Utah and Nevada. . .
The study predicts that the drought could be as severe as the Dust Bowl
of the 1930s. . .
Five of the 10 fastest-growing states are in the Southwest, and nearly 1
million newcomers moved to Arizona, Nevada, Texas, Utah and Texas last
year, according to 2006 census data.
