Without getting in to the whole climate changing thing - I just read that the polar ice cap and a lot of old Greenland ice is going away rapidly. How much does it have to diminish so that we don't get polar vortexes and the jet stream doesn't get ahold of any cold air because there isn't any? It has been discussed at length about how winters are not what they used to be as far as snowfall and overall duration of 'winter'. Or are we in unknown territory?
