Climate models indicate that as global temperatures increase, global precipitation also will rise, but that it will become more heterogeneous as well. How will that affect soil moisture, a quantity that often is ignored but has large impacts on agriculture, flooding, and weather? Wu et al. report results from a suite of climate models that show that soils in middle and high northern latitudes will get wetter in the wettest months and drier in the driest months. This increase in the annual range of soil water content will affect water resource management, plant adaption, and agriculture, particularly in regions where snowmelt supplies a significant portion of the seasonal water supply.
