Simply (or maybe not so simply)...I think those that have such responses, and snow lovers in general, don't want to admit it's a possibility (not 100% certain but possible) that the snow climo could be permanently altered. I don't think any of us WANT that to be true...so is the resistance/cognitive dissonance really such a surprise? And of course there are those that don't want to be wrong anyway, lol
I think we need to be real about where things may be, yet understanding of how we're feeling about the POSSIBILITY of a new reality. No matter what, anybody that loves snow may have to adjust if it's true because it would potentially suck for everybody...so let's just be patient with each other as we grapple with that possibility.
