In case you still think that Global Warming is a hoax (especially when looking at the deep winter conditions of January 2008 in the midwest of the United States), then contemplate the following picture which shows the European Alp's (still) largest glacier, the Aletsch glacier in 1900 and 2005:

According to Wikipedia, "the Aletsch Glacier receded by 100m (~100 yards) between 2005 and 2006."
