3. Sarah Palin
Retired half-term governor, Alaska
No state suffers more from global warming than Alaska, where glaciers are already melting, methane is bubbling up through the permafrost, and animals are being forced to alter their migration patterns. Yet Palin, the host of Sarah Palin's Alaska, continues to ridicule climate change as a "bunch of snake-oil science." On her reality show, Palin tromps through the wilderness gushing about what she has called "the grandeurs of God's creation." But in the real world, she disses climate scientists, trashes clean-energy jobs and throws her political weight behind candidates who deny the reality and risks of global warming. (More than half of the 64 candidates she endorsed in the midterm elections won.) Her low point came during the BP oil spill in the Gulf, which, with typical bang-your-head-against-the-wall logic, she blamed on "radical environmentalists" who had locked up "safer drilling areas" like the Arctic National Wildlife Refuge.
