Maine's 17 ski areas contribute $300 million a year to the state's economy, providing recreation for Mainers and visitors. Winters in the Northeast could warm by 8°F to 12°F by end of the century if emissions continue unabated. These milder winters are expected to shorten the average ski season, increase snowmaking requirements, and drive up operating costs in an industry that has already contracted in recent years. As shown in the graphic above, under the higher-emissions scenario, western Maine is projected to be the only area in the entire Northeast able to support viable ski operations by late-century. However, in order to stay open, resorts in this area would require substantial increases in snowmaking capacity and, therefore, operating costs.
