Typically, it takes seasons for a standard drought to develop — with a flash drought, however, expedited drying arises in just weeks. Thus, it’s quite difficult to prepare for them. However, scientists at NASA’s Jet Propulsion Laboratory in Southern California may have a solution. At the end of April, they released a study about their discovery of a way to recognize signs months in advance of a flash drought event. Signs from space, that is. You just have to look for the glow — or, well, lack thereof. It would appear that, in anticipation of a flash drought, the “glow” of a plant begins to dim, and it’s possible to capture such dimming with spacecraft orbiting our planet.
