The Earth is warming. That's observable data and is not up for discussion or denial (which differentiates it from an opinion or belief).
Politically, you can argue who is to blame and start pointing fingers, but there's really no "warming crowd". There's just going to be a lot of "dead" when the ecosystem changes due to climate (this one is my opinion, but we can wait till it becomes an observation).
But back to the OP: Glacier is open year round, as someone already stated. I'd buy/rent a -40º sleeping bag if you're visiting during the winter months, and keep it in the car with you while you drive.
