The trouble is, things are heating up out there. That could mean shorter seasons and less snowfall. The reason is global warming, caused by heat-trapping pollution. We can fix the problem, as long as we start soon. That’s why the Natural Resources Defense Council and the National Ski Areas Association have teamed up to Keep Winter Cool. Keep Winter Cool is a partnership between NRDC (Natural Resources Defense Council) and the National Ski Areas Association (NSAA) to raise visibility and public understanding of global warming and spotlight opportunities that exist right now to start fixing the problem.
