==Climate change==
Winter season lengths are projected to decline at ski areas across North America and Europe due to the [[effects of global warming]]. In the United States, winter season lengths are projected to decline by more than 50 percent by 2050 and by 80 percent by 2090 if greenhouse gas emissions continue at current rates.<ref>{{cite journal |title=Projected climate change impacts on skiing and snowmobiling: A case study of the United States |journal=Global Environmental Change |volume=45 |pages=1–14 |doi=10.1016/j.gloenvcha.2017.04.006 |year=2017 |last1=Wobus |first1=Cameron |last2=Small |first2=Eric E. |last3=Hosterman |first3=Heather |last4=Mills |first4=David |last5=Stein |first5=Justin |last6=Rissing |first6=Matthew |last7=Jones |first7=Russell |last8=Duckworth |first8=Michael |last9=Hall |first9=Ronald|last10=Kolian|first10=Michael |last11=Creason |first11=Jared |last12=Martinich |first12=Jeremy |doi-access=free}}</ref> About half of the 103 ski resorts in the Northeastern United States operating in 2012 may not be able to maintain an economically viable ski season by 2050.<ref>{{cite journal |url=https://www.academia.edu/3208898 |title=Managing for climate change in the alpine ski sector |journal=Tourism Management |volume=35 |pages=244–254 |format=PDF |publisher=Elsevier |access-date=February 3, 2019 |last1=Scott |first1=D. |last2=Dawson |first2=J. |doi=10.1016/j.tourman.2012.07.009 |year=2013}}</ref> In Europe, half of the glacial ice in the [[Alps]] has melted and the [[European Geosciences Union]] projects snowpack in the mountains could decline 70 percent by 2100 (however, if humans manage to keep global warming below 2&nbsp;°C, the snow-cover reduction would be limited to 30 percent by 2100).<ref>{{cite web |url=https://www.egu.eu/news/323/less-snow-and-a-shorter-ski-season-in-the-alps/ |title=Less snow and a shorter ski season in the Alps |format=PDF |publisher=European Geosciences Union |access-date=February 3, 2019}}</ref>
