DID YOU KNOW?
- Snow-based recreation contributes $67 billion annually and supports over 900,000 jobs in the United States.
- The Rocky Mountain region of the United States consistently records the highest total visitation rate in the US for snow sports; the Northeast is second.
- April snowpack in the Western United States has decreased by about 23% since 1955.
As air temperatures continue to rise and the winter season becomes shorter in the United States, the season for cold weather activities such as skiing, snowboarding, snowmobiling, outdoor ice hockey and skating, ice fishing, and winter hiking will also become shorter.
EPA. Change in Total Snowfall in the Contiguous 48 States, 1949-2015
Since 1949, nearly 80% of weather stations across the contiguous 48 states have recorded an increase in winter precipitation falling as rain instead of snow. With a future projected increase in temperature and reduction in snow cover, snow sports such as skiing, snowmobiling, and snowshoeing may become limited.
For ski resorts in the Northeast to stay viable they require average ski season lengths of at least 100 days, nights cold enough to produce artificial snow, and snow during winter holidays when winter tourism is high. Projections indicate that most resorts in the region will be vulnerable by the end of the century because warmer temperatures will prevent them from meeting these criteria. As a result, resorts will be required to produce more artificial snow, likely resulting in increased resort attendance costs due to increased costs associated with water and energy usage.
Snowmobiling and cross country skiing are projected to be even more vulnerable. Machine-made snow has not typically been used to support these sports because it cannot produce enough snow to cover miles of trails.
EPA: Change in Ice Thaw Dates for Selected US Lakes, 1905-2014
Freeze dates for Northern US lakes are occurring later in the year than they did in the past and thaw dates are occurring earlier, reducing the season for outdoor ice hockey and skating and ice fishing. Freeze dates are occurring at a rate roughly half a day to one day later per decade since 1905 and thaw dates have advanced up to 23 days earlier in the past 109 years.
The National Hockey League (NHL) has acknowledged in their 2018 NHL Sustainability Report that changing climates and increasing resource restraints adversely affects their sport. Mike Richter, NHL Green Ambassador and US Hockey Hall of Fame Goalie, has stated, “Our sport is affected by climate change more than any other. Our game was born on the frozen ponds of North America. The availability of free ice creates the culture we love. We want everyone to have access to our sport regardless of age or economic position. In order to do so, we need to preserve the outdoor rink.”
HIKING ON PUBLIC LANDS
Trends in April Snowpack in the Western US, 1955-2015
Snowpack attracts hikers and tourist throughout the year in many US National Parks, but decreases in snowpack have been observed in the western United States since 1955. In the winter, hikers are able to view snowcapped mountains and glaciers. As winters become warmer, the snowpack on top of mountains and the size of glaciers will decrease. For example, at Olympic National Park in Washington State, Blue Glacier on Mount Olympus lost three football fields in length between 1987 and 2010.
Warmer winters and decreased snowpack also impact the spring and summer hiking season, as there is less water for wildlife, plants, and humans living downstream. Yellowstone National Park now experiences approximately 30 fewer days per year with snow on the ground than there were in the 1960s. This has reduced the amount of spring snowmelt available to deliver freshwater that supports vegetation and wildlife such as migrating bison, spawning trout, and pollinators.
