Kat J. Bormann, Jet Propulsion Laboratory, Caltech . Data & Results: . There is extensive surface and satellite-based evidence of significant declines in Northern Hemisphere spring snow cover starting in the mid 1980’s in response to recent warming. However, our ability to monitor snow cover and trends in mountain regions is severely hampered by limitations in current satellite systems. Consequently the trends in the mountains are much less clear..
