Changes In Earth's Orbit Were Key To Antarctic Warming That Ended Last Ice Age 180
vinces99 writes "For more than a century scientists have known that Earth's ice ages are caused by the wobbling of the planet's orbit, which changes its orientation to the sun and affects the amount of sunlight reaching higher latitudes, particularly the polar regions. The Northern Hemisphere's last ice age ended about 20,000 years ago, and most evidence has indicated that the ice age in the Southern Hemisphere ended about 2,000 years later, suggesting that the south was responding to warming in the north. But new research published online Aug. 14 in Nature (abstract) shows that Antarctic warming began at least 2,000, and perhaps 4,000, years earlier than previously thought."

I mean, you don't let ice build up on your roof, in your freezer, or on airplanes... ice is always bad unless it is in my drink!
Earth's balance off because of too many people? (Score:4, Funny)
Maybe the earth's orbit changes right now are because there are too many people living in one area and they are weighing down the earth like a seesaw? Like if too man people live on one side of an island the island tips over?
