Snow isn’t just a fun thing to slide on… It’s a crucial source of water, a major economic driver, and vital for natural ecosystems to function.

Here are the general trends scientists predict for the Intermountain region of Montana: 

■ More heat.Temperature increases in the West are likely to be even greater than the projected 3° to 10°F worldwide increase by the end of the 21st Century.

■ Smaller snowpacks.It is very likely that more winter precipitation will fall as rain.

■ Earlier snowmelt.Warming earlier in the year very likely will melt snowpacks sooner.

■ More evaporation and dryness.Higher temperatures would increase evaporation from streams and reservoirs, soil dryness, and the needs of crops and other plants for supplemental water.

■ More flood-control releases.Warming in the mountains in late winter and early spring very likely will increase snowmelt and river flows then, and reduce them later in the year.

■ Less groundwater.Snowpacks also are essential contributors to the West’s groundwater.

■ More legal restrictions.Environmental constraints, which sometimes now limit the water available for consumptive use in the West, may be triggered more often as a result of climate disruption.

■ More droughts.Climate disruption could lead to more intense, frequent, and longer-lasting droughts in the interior West.

A sufficient snowpack is essential for the ski industry in the west.

  • More than 23 million people participated in winter sporting activities (measured through visits to downhill ski resorts and snowmobiling), adding an estimated $12.2 billion in economic value to the U.S. economy, through spending at ski resorts, hotels, restaurants, bars, grocery stores, and gas stations.          

  • Some 38 states experienced added value to their economies from downhill ski and snowboard visits, and snowmobiling trips.
