Without getting too far into the global warming side of things, I think most, if not almost everyone, is in agreement the earth is warming, and what is under contention is under what timeframe, how much, and why.
The part I don't understand is conflating receding glaciers and ice with snowfall. The two can absolutely be independent.
The Wasatch gets a ton of snow, and has not had glaciers for 10,000-30,000 years. We get a ton of snow- no glaciers. To form, glaciers need both snow, and cool summers to minimize melt.
Just because one is disappearing doesn't mean the other is in imminent danger. My (exceptionally limited) understanding of the science is that certain areas can be expected to see more snow from a warming climate- the warmer climate allows more moisture in the air, orographic lift does the same thing it always does, only with more moisture to wring out. Other areas can see increased snowfall from receding sea ice- open water in the Arctic means evaporation, which means Alaska sees more snow as the air has access to a lot more moisture. Which happens to cause glaciers to form/grow in areas that currently do not see enough snowfall to do so in the upper latitudes.
Considering the alps have a ton of vertical relief to see said lift (and lots of high altitude- more in both regards than the Wasatch), I am skeptical of a blanket assertion that everywhere in the alps can be expected to lose snow. Weather patterns can be expected to change, in same ways dramatically. But this will not turn everywhere into a desert, which seems to be the assumption.
Which leads to the next obvious hole in Eagles' theory- Why would European skiers come to Park City instead of just going to higher-altitude and/or resorts in the alps that see more snow as a result of climate change (or just more snow than their competitors)? If we get to the point where there is no snow in 14,000 foot mountains, we have far greater problems than where we are skiing.
