“It’s worrisome for the start of the season,” said Ms. Williams, 18, a member of the ski team at nearby Colby-Sawyer College. “The winter is obviously having issues deciding whether it wants to be cold or warm.”
Her angst is well founded. Memories linger of last winter, when meager snowfall and unseasonably warm weather kept many skiers off the slopes. It was the fourth-warmest winter on record since 1896, forcing half the nation’s ski areas to open late and almost half to close early.
Whether this winter turns out to be warm or cold, scientists say that climate change means the long-term outlook for skiers everywhere is bleak. The threat of global warming hangs over almost every resort, from Sugarloaf in Maine to Squaw Valley in California. As temperatures rise, analysts predict that scores of the nation’s ski centers, especially those at lower elevations and latitudes, will eventually vanish.
