Cryogenic Future World?

A few weeks ago, the United States had rallies in many cities to draw attention to the threat of global warming, or more generally, climate change.  Now that is a subject itself, because what does one mean by "global warming?"  Does that mean "the earth's atmosphere is heating up and we need to understand and do something about it" or does it mean Al Gore's Imminent Apocalypse theory?  Might the reality of the situation lie somewhere in between?  My problem with such movements is when questioning the magnitude of the variables involved in climate change draws accusations of "global warming denial."  I didn't graduate with honors from a major research university for being a "blathering idiot," Congressman DeFazio.

Someday I'll go deeper into the global warming equation and models, but for now I'll go straight to the point that there's also significant evidence that the world is only a decade away from dipping into another Little Ice Age.
