Ski Resorts Are Reinventing Themselves in the Face of Global Warming

Marshall Heaven of Greenwich, Connecticut got tired of waiting for the snow to fall, so he bought two Backyard Blizzard snowmakers and can now promise 15-foot drifts as early as late November .... Even though it's late January in Mason Township, Maine, Steve Crone of New England Dogsledding tethers his eager canines to a golf cart. "We'd rather have snow," he says with some embarrassment ... Fifteen-year-old Cameron Sonley of Peterborough, Ontario, where the winter was two degrees warmer than usual in the 2006-2007 season, complained last March that because of high temperatures he was only able to go snowboarding four or five times, instead of his usual dozen .... In Staten Island, New York, skaters have been thwarted for three straight years as pond ice failed to thicken ... Janisse Ray, an outdoor recreation enthusiast in Danville, Vermont, got so frustrated when the West River hadn't frozen by last January that she donned a wetsuit and floated downstream in an inner tube, holding aloft a sign that said "Where's winter?"

Where indeed? Since 1970, average winter temperatures in New England have increased 4.4 degrees Fahrenheit. In the U.S., 2006 was the warmest year on record, and 1998 is number two. The last eight five-year periods were the warmest since we began taking national records 112 years ago. During the past 25 to 30 years, says the National Climatic Data Center, the warming trend has accelerated, from just over a tenth of one degree Fahrenheit per decade to almost a third of a degree.

By the end of the century, temperatures in the Northeastern states are likely to rise by eight to 12 degrees Fahrenheit (at which time snow-covered days will have been reduced to half of what we traditionally experience). A 2007 report from the Union of Concerned Scientists on the Northeast predicted that, under some higher-emission scenarios, "Only western Maine is projected to retain a reliable ski season by the end of the century, and only northern New Hampshire would support a snowmobiling season longer than two months." Warmer weather and changing precipitation will result in a fundamental change to winter recreation and what the report called "the winter landscape."

Our Changing Climate

When Nat "King" Cole sang about "Jack Frost nipping at your nose" and "folks dressed up like Eskimos" in 1946, a white Christmas was standard fare in many parts of America. But with today's milder winters, Jack Frost is not such a regular visitor and hats and gloves are spending more time in the closet.

The Hood Museum at Dartmouth College recently mounted a major exhibit of Inuit clothing, tools and art -- materials adapted to one of the coldest places on Earth. But the once-stable climate there is changing. The Arctic Climate Impact Assessment said in 2004 that Arctic temperatures are now rising at nearly twice the rate of the rest of the world (as much as 14 degrees Fahrenheit on average over the next 100 years), reducing sea ice and melting frozen soils. It's been widely reported that Alaska's polar bears are probably doomed by 2050, but the scale of this climatic shift will likely do much more -- completely changing the culture of the Arctic region.

Though there are still a few diehards, the overwhelming majority of scientists now believe that climate change is at least partly responsible for our steadily rising thermometers. Obviously, global warming science is complex and hardly monolithic -- some parts of the world continue to experience very cold temperatures and record snowfalls, just as the climate models say they will. You might even be reading this as a blizzard fulfills the promise of a white winter. But the overwhelming trend is clear: it's getting warmer, and winter is losing force, intensity and duration, changing America's ingrained habits in the process. If you've ever enjoyed ice skating, sledding, skiing, snowboarding or building a snowman, you should know that the future of these enshrined institutions is by no means guaranteed.
