is responsible for up to 60 percent of changes contributing to dwindling water
supplies in the arid and growing West, a new study finds.

Those changes are likely to accelerate, says the study published Thursday
in Science magazine, portending "a coming crisis in water supply for the western
United States."

The study is likely to add to urgent calls for action already coming from
Western states competing for the precious resource to irrigate farms and quench
