I was curious. Is snow coverage increasing or decreasing in N. America. I know there a lot of dire predictions out there concerning the future of our sport, considering global warming models made by scientists.
Rutugers U apparently does the definitive data tracking of snow coverage on a monthly basis. Coverage = Extent.
I grabbed the N America minus Greenland numbers (we don't ski much there) and imported Jan/Feb into excel and then created a graph of the Jan/Feb average from 1967, which is the earliest data that is available. (I couldn't add March because the free version of OutWit Hub which I used to grab the number from the web page only allows a limited amount of data imported)
The trend is up since 1967 - that's the solid black line. The blue line is the Jan/Feb average million sq km for each year. The black squiggly line is the 5 year moving average, which has been on a solid uptrend the past 10 years.
