Looking up from my keyboard, I saw a perfect illustration of what’s happening underneath ice sheets in Greenland and Antarctica. Two recent snowstorms dumped eight inches of heavy snow, followed by an afternoon of very warm air and a sharp rain. The rainwater lubricated the snow packs on my neighbor’s roof and they began to slide. The temperature fell quickly with nightfall, leaving us with a perfect example of dynamic ice.
