Impact of Climate Change on Snow Coverage

Research indicates that by the end of the century, significant areas in the United States, particularly in New England and the Midwest, will experience a dramatic reduction in deep snow cover due to climate change. Current projections suggest that only high-altitude regions in the Rocky Mountains will maintain their snow cover, while other areas can expect an almost complete absence of deep snow. This loss of snow is likely to have wide-ranging effects on local ecosystems, water storage, and seasonal flooding, as snow plays a crucial role in groundwater replenishment throughout the year. The implications extend to human activities, such as skiing, where resorts are already struggling to produce artificial snow, signaling a shift in winter recreational activities for future generations.
