Key Climate Changes:

  • Since the 1970s, December-February temperature increases have ranged from 1 to 2 degrees in the Pacific Northwest to about 4 degrees in the Northeast to more than 6 degrees in Alaska.
  • Winters are getting shorter, too. Spring arrives 10-14 days earlier than it did just 20 years ago.
  • Global warming is bringing a clear trend toward heavier precipitation events.

    • Many areas are seeing bigger and more intense snowstorms, especially in the upper Midwest and Northeast.
    • Large economic uncertainty and potential losses are in store for many communities, especially in regions where winter recreation provides significant tourism revenue.
      • A number of Northeastern ski areas are likely to see a 25-45% decline in the length of their ski season by the 2070s.
      • Lakes across the Midwest are freezing later and have thinner ice, often leading to ice conditions to dangerous for safe ice fishing
      • The report also includes recommendations for reducing the risk:
        • Curbing global warming pollution to minimize future oddball winter weather.
        • Accounting for greater variability in snow removal and flood management programs.
        • Safeguarding wildlife, fish and habitats from more unpredictable winter weather.
