The great snow cover debate: Are we seeing more snow or less?

According to current computer models, snow cover should have been decreasing year-on-year since the mid-20th century. The models make this claim because of global warming. They also predict that this trend will continue and even accelerate. They suggest that soon many countries will no longer experience snow.Show more

But, what has actually happened to snow cover?

In this video, we compare the claims of the computer models to the observed historical records. We find the models got it wrong for all four seasons.
