How would Al Goreleone explain this snowfall history? In the 1970s, when Newsweek claimed we were heading into a new ice-age, there were several years of below average snowfall. During last year's below average snowfall, people claimed it was further proof of global warming. Climate trends vary dramatically. An average of 30 feet could be the result of 10 feet in year one and 50 feet in year two. Can you say "standard deviation"?
