You're arguing from ignorance, Edgar The Guest. One hardly knows where to begin, so one won't. The information you refuse to consider is all out there.

I understand that one of the biggest risks of being killed in a US blizzard to is to offer to help someone who's stranded.

By the way, anyone wanting to use one snowstorm as evidence against global warming may be interested to know that I was in shorts and t-shirt in sunny London this morning in a near-record 16°C, or 61°F. And that December was by far the warmest in England since records started over 300 years ago. But I won't use either fact alone in evidence to support man-made global warming, as that isn't what scientists do.
