Here is an interesting take on the Lemming principle as it relates to Global Warming. I wonder how many times throughout history a perceived majority consensus has led an entire nation astray? A couple notable examples come to mind.

The Science of Gore's Nobel

I particularly like this paragraph, as it pretty clearing identifies where much of this Global Warming fanaticism is coming from.

"Now let's suppose a most improbable, rhapsodic lobbying success for Mr. Gore, Mr. Khosla and folks on their side of the table--say, a government mandate to replace half the gasoline consumed in the U.S. with a carbon-neutral alternative. This would represent a monumental, $400 billion-a-year business opportunity for the green energy lobby. The impact on global carbon emissions? Four percent--less than China's predicted emissions growth over the next three or four years."
