Here's the thing: we don't know what's going to happen in any particular year or over the short term, but we do have significant risk, and even probability, that anthropomorphic (human activity-caused) climate change will at some point in the future make life very different, and often very difficult for much if not most of the world's population. Best probabilities I have seen is that what we experienced in 2014-15 will be the norm in about 50-70 years, at least in the PNW. This impacts water management and agriculture pretty seriously. As far as skiing, it will likely be pretty volatile and unpredictable. You might have major ski resorts that can operate some years, and not others, which impacts the viability of ski resorts to operate at all.
So (I can hear the arguments), what about that uncertainty of when this will have an impact or if it will happen at all? Why take it too seriously now until we know for sure, for sure?
Well, why take than kind of chance? Do you care if you kids or grandkids get to ski? I'm sure we all will be able to enjoy skiing and boarding throughout the rest of our lifetimes, but the experience may deteriorate over that time, be less predictable and reliable than it is now (or even less so than it is now), and not available at all for subsequent generations.
So why take that chance, when the costs of energy efficiency and green power are not actually that much of a burden (IMHO)? Actually business and individuals that reduce their carbon footprint tend to save money in the process. So what's really the issue? Hate the idea of being wrong?
