Climate: Our Current Ice Age
I always had thought that we were living in an inter-glacial. Technically, no. Ice on the poles signifies a glacial period, and we are just fortunate enough to experience a minor retreat of the fluctuating glacier over the past ten thousand years. When the next glacial advance begins is a matter of debate, but it will turn New England back into a polar environment, buried under a mile of ice, when it decides to return. With dire results for our property values.
And now it turns out that greenhouse gasses may not protect us from that fate. Carbon dioxide may cause global cooling. Oh, man - not yet another reason for the enviro-anarchists to return us to the stone age.
