Video: NASA satellites capture the ground impact of droughts, from 2002 to today

While the effects of droughts reveal themselves in the short term through arid fields and withered riverbeds, their ongoing impact reveals itself most readily below the crust of the Earth. Ground water, both right under the surface and deep underneath it, suggests how months and years of dryness will affect us in the long run.

In the video below, NASA satellites capture these effects in color-coded -- and fairly alarming -- form. Spooling out are ten years' worth of data, provided by the Gravity Recovery and Climate Experiment (GRACE) science team and rendered visually by Chris Poulsen of the National Drought Mitigation Center.
