Scientists say groundwater can be used to store greenhouse gas, but water wars are starting

Scientists have found that underground water can be used to store the main greenhouse gas, but Tara Lohan of The Nation reports that "The battle for control over the world's dwindling freshwater resources has already begun." Most of her story is about conflicts in Asia, but she also reports on tension between the U.S. and Mexico over the Colorado River and its recharge of groundwater.

The study about groundwater storage of carbon dioxide was done by researchers at the University of Edinburgh and the University of Manchester. For a story by Michael Kahn of Reuters, click here.
