Globally, precipitation over land has likely increased since 1950, consistent with increases in total atmospheric moisture. Climate models project an increase in Arctic precipitation, a transition from snowfall- to rainfall-dominated climates, and a higher frequency of heavy precipitation events.
Ice loss from the Greenland Ice Sheet has immediate and global influence on sea level rise, with impacts including coastal erosion, saltwater inundation of freshwater resources, and increased flooding frequency.
