I don't know whether it's controversial, but rather, uncomfortable. A "controversial" reaction seems more like emotion to me! We all have uncomfortable things we either don't want to/aren't ready to accept. And there's mental resistance/negative reaction when seeing said realities. All the reaction is stemming from that place of not wanting it to be true, and the emotions tend to outweigh the logical side of things in conversation because of it. Psychologically, we don't tend to enjoy seeing a reality that points to getting less of something you get joy out of.
So yeah, logically, it's getting warmer. But I challenge ya to find any snow lover that doesn't feel a certain way about that, lol Some handle it better than others!
