I'm flipping channels and come across the ScienceHD channel showing "Snowball Earth." The summary reads:
Scientists postulate that the Earth was once sheathed in ice and complex animals evolved when the planet thawed, due to the release of carbon dioxide.
Wow, carbon dioxide is good for little cuddly bunny rabbits and other living things? Who would've thought it?
Of course, this postulate and its focus on carbon dioxide, as opposed to water vapor, solar activity or cosmic rays shows that it's merely setting the stage from AGW theory. Of course, humans weren't driving SUVs to pull "snowball Earth" out of its icy covering its first time. In fact, humans weren't around at all.
Which brings us back to the religious nature of the AGW crowd. It obviously wasn't humans that caused this ancient warming, but this time around we know it's our fault.
