New Ice Age Predicted — But Averted by Global Warming?

Deep ice sheets would cover much of the Northern Hemisphere thousands of years from now–if it weren’t for us pesky humans, a new study says.
Emissions of greenhouse gases–such as the carbon dioxide, or CO2, that comes from power plants and cars–are heating the atmosphere to such an extent that the next ice age, predicted to be the deepest in millions of years, may be postponed indefinitely (quick guide to the greenhouse effect).
“Climate skeptics could look at this and say, CO2 is good for us,” said study leader Thomas Crowley of the University of Edinburgh in Scotland.

Basically, Crowley and company are suggesting that the Fallen Angels premise is correct–without the additional carbon dioxide from human activities, the Earth would be heading toward another Ice Age.
