For many states, the rainy season is over, and most of the Western United States is now locked into a fourth consecutive year of drought. The imminent dry summer is particularly foreboding for California, where more than 44% of land area is engulfed in an exceptional level of drought. This was the highest such share nationwide and the kind of water shortage seen only once a century.
According to a study by the National Aeronautics and Space Administration (NASA), “Droughts in the U.S. Southwest and Central Plains during the last half of this century could be drier and longer than drought conditions seen in those regions in the last 1,000 years.” The likelihood of such a drought is 12%, NASA scientists estimated.

The drought in California is persisting even after significant rainfall. It’s a bad situation, but it is absolutely nothing compared to what is in store for the Central Plains and Southwestern region of the United States in the next 100 years.
Scientists had already found that the Southwestern United States were at great risk of experiencing a significant megadrought (in this case meaning drought conditions that last for over 35 years) before the end of the 21st century. But a new study published in Science Advances added some grim context to those predictions. Continue reading
