SUMMARY

1 min 52 sec

Signs of a drought are easy to recognize when the ground cracks, plants shrivel and lake levels plummet. But surviving a drought requires planning and the ability to recognize the markers of the problem before the drought gets severe. How do we know when a region may be experiencing an early drought? Dr. Heidi Cullen talks to NASA scientist Molly Brown, who relies on sophisticated satellites for the answer.
