The sample size isn’t large enough to know for sure one way or another, but given that AGW is accelerating rather than just steadily increasing, it’s worth keeping an open mind about his ideas. The snow decline is already happening in some southern areas, and it started before 2016. It’s a logical assumption to make that with additional warming since then, some areas farther north reached a tipping point. There isn’t anything wrong with discussing ideas about what the future holds and trying to figure out what is going on. There is no malicious agenda pushing going on here. If Bluewave is right he’s right, if he’s wrong he’s wrong. Maybe he’s right about some things, wrong about others (I would bet on this one). We all have our biases, but Bluewave is a fairly objective poster.
