     abstract = "{Changes in terrestrial water storage (TWS) are a critical indicator of
        freshwater availability. We use NASA GRACE/GRACE-FO data to show
        that the continents have undergone unprecedented TWS loss since
        2002. Areas experiencing drying increased by twice the size of
        California annually, creating ``mega-drying'' regions across the
        Northern Hemisphere. While most of the world's dry/wet areas
        continue to get drier/wetter, dry areas are now drying faster
        than wet areas are wetting. Changes in TWS are driven by high-
        latitude water losses, intense Central American/European
        droughts, and groundwater depletion, which accounts for 68\% of
        TWS loss over non-glaciated continental regions. ``Continental
        drying'' is having profound global impacts. Since 2002, 75\% of
        the population lives in 101 countries that have been losing
        freshwater water. Furthermore, the continents now contribute
        more freshwater to sea level rise than the ice sheets, and
        drying regions now contribute more than land glaciers and ice
        caps. Urgent action is required to prepare for the major impacts
        of results presented. Drying continents, extreme drought, and
        groundwater depletion are shrinking water availability and
        increasing sea level rise.}",
