10,000 years ago we were in an ice age. The glacieres melted, agriculture was born, and the human race flourished. Wether the Earth warms or cools the climate changes and always has regardless of our use of incandescent, versus flourescent bulbs. At least with the technology we have now we are better equipped to deal with the climate whatever it does.

Washington, Adams, Jefferson, and Franklin would be shocked and ashamed.
