What's worse than skiing on mud? How about snowmobiling on rocks? Snowmobiles may become relics as heavy snowfalls retreat to the far north. Unlike skiing, snow-making machines won't be capable of bailing out snowmobiling. Blasting across miles of snowpack requires more snow than any machine can realistically produce.
Since snow-making can't help, snowmobiling season may drop to less than 50 days in many regions, warned research published in Mitigation and Adaptation Strategies for Global Change.
Besides killing snowmobile sports, less snow build-up over the winter results in lower flows in streams and rivers in the spring. Many species evolved to depend on the rush of spring waters. Humans, too, may go thirsty, since many cities, including Los Angeles, draw water from melting snow in distant mountains.
