One fact which is obvious to everyone except (1) climate scientists and their (2) useful idiots, is that colder winters have greater snow cover. Mosher (category 2) was arguing this with me last night, before I finally blocked him on twitter.
When winters are colder, the freeze line moves closer to the equator and snow extent increases. During warmer winters, the freeze line moves towards the pole, and snow extent decreases.
North American winter (December-February) snow extent has been increasing for fifty years.

US winter maximum temperatures have generally been declining, after some very warm winters in the 1930s and 1950s.
Plotting winter snow extent vs. average winter daily maximum temperature, the relationship is obvious. Warmer winters have smaller coverage of snow.
The relationship between cold and snow is also obvious to everyone outside the climate science community.
