Global groundwater crisis may get worse as the world warms!

NASA’s Gravity Recovery and Climate Experiment (GRACE) satellite system has recently shown that between December 2004 and November 2013, the Colorado River basin lost nearly 53 million acre feet of freshwater, which is double the total volume of the country’s largest reservoir — Lake Mead in Arizona.  What could this mean?  The redistribution of water around the planet by climate change, with wet areas getting potentially wetter and dry areas drier, could further stress global water supplies.  The poor management of ground water supplies in the coming decades could be extremely disruptive, in the form of declining agricultural production, reductions in energy generation and the possibility of huge spikes in food prices.  The picture below is an image obtained from GRACE satellite data showing California’s groundwater depletion in recent years.
