Study finds steepest drops in areas of the Northern Hemisphere reliant on snow for water.Scientific data from ground observations, satellites, and climate models have not agreed on whether climate change is consistently chipping away at the snowpacks that accumulate in high-elevation mountains and provide water when they melt in spring. This complicates efforts to manage the water scarcity that
