Talk to Durwood Zaelke, for example. Zaelke is a grizzled veteran of the climate wars: He was in Kyoto in 1997 when the world's nations drafted a treaty promising to curb warming, and he has watched that promise fizzle while the planet's temperature continues to rise.

Zaelke says the Kyoto treaty focused too much on the main greenhouse gas: carbon dioxide.

"I mean, it's like picking a fight with the biggest bully in the schoolyard," he says with a note of lament. "You know, you get your lunch money stolen, you get your pants pulled down, and you get sent home humiliated. We've made about that much progress with CO2."
