shweet: the problem is that until recently they haven't receeded this early/much. hence, resorting to blankets.
uart has the right idea. kinda.
it WILL work, but not on such a large scale i suspect. blankets insulate. things that insulate prevent the transfer of energy... in this case heat. so a blanket keeps you warm by preventing heat from leaving your body. a blanket would keep a glacier cold by preventing heat from entering.
