Today's email brought this link to an article about melting glaciers and the effect on global climate. Besides rising sea levels, the two biggest impacts are the shifts in the jet stream (you know, the high level air stream movement that keeps thunderstorms moving along rather than dumping all their rain in one place) and the loss of glaciers & snow packs as water reservoirs for areas where the regular runoff is used for drinking water and hydro-power production. In the US, that means Alaska, California, and probably many of the Rocky Mountain States. It's worth reading the article to get a better understanding of why people are saying this is a big deal.
