The EPA forecasts temperatures to increase by between 0.5 °F and 8.6 °F globally with a likely increase of 2.7 °F by the year 2100, and an average increase in temperatures in the US of between 3 °F and 12 °F by the year 2100. Furthermore, scientists predict that snow cover in the northern hemisphere will decrease by 15% by the end of the century with snowpack decreasing and snow seasons shortening concurrently. These predicted changes in temperature and snowfall patterns will induce ski resorts to rely more heavily upon artificial snow which uses significant amounts of water and electricity. As a result, ski resorts will further contribute to the production of greenhouse gases and the issue of water scarcity.
