Climate Change: Momentum, But Much Work Remains

Climate change might take a back seat to global financial challenges at this G20 Summit, but it's still a top priority for some groups.
Jennifer Havercamp of the Environmental Defense Fund is hoping this G20 lays the groundwork for a successful agreement at the Climate Conference in Copenhagen in December.
"I'm encouraged by momentum but still a lot of work is (left) to be done."

Havercamp says the fact that G20 nations are felling financially strapped is a real concern......"A lot of money is needed but the cost of inaction is greater, and if we wait, the cost will only increase."

She says a global cap on carbon would lead to much less expensive ways to reduce emissions.
