It has become difficult to rely on natural cold and snow even in traditional winter sports venues. This is because of increased temperatures caused by global warming. This may not be the biggest problem caused by climate change, but it is one that has attracted a certain amount of helpful attention. Perhaps the North American visitation of the Arctic Vortex, which has made some people think that climate change is not real, is partly offset by a Winter Olympics with more than its share of problems, including injuries and lost medals, caused by crappy snow conditions.
Also, it is kind of a “First World Problem.” Such problems tend to receive extra attention and the demand for solutions may be more likely addressed. I imagine that the slopes of the better ski resorts are populated by a relatively high proportion of people who assume climate change can’t really affect them (because not much does), and perhaps by a larger percentage of people who feel, incorrectly, to be financially threatened by measures to curb climate change.
Meanwhile, science not only tells us that global warming is real, but it also tells us how to adapt, at least a little. From the American Chemical Association, a video on how they make snow:
