Politically, climate change is off this year's campaign agenda. Jobs, the economy and social issues are front and center.
But scientists are working as hard as ever to figure out how much the Earth is warming and what to do about it. Some now say it's time for a new strategy, one that gets faster results.
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.
