SAN DIEGO, Aug. 22 (UPI) -- The American West continues to suffer one of the worst droughts in history. And as new GPS measurements confirm, the ground is actually rising as water continues to be sucked from the soil.
By analyzing ground positioning data collected by GPS stations across the West, researchers with Scripps Institution of Oceanography at UC San Diego estimate that, over the last two years, the intense heat and lack of rain -- plus the drinking needs or major cities and the water-sucking irrigation systems of area farms -- has sapped some 63 trillion gallons of water from the earth.
