BERLIN (REUTERS) - Faster action is needed to keep global warming to agreed limits and delays until 2030 could force reliance on technologies to extract greenhouse gases from the air, a UN report said on Sunday.

The study, drawing on the work of more than 1,000 experts, said a shift from fossil fuels to low-carbon energy such as wind, solar or nuclear power was affordable and would shave only about 0.06 percentage point a year off world economic growth.

"We have a window of opportunity for the next decade, and maximum the next two decades" to act at moderate costs, said Ottmar Edenhofer, co-chair of a Berlin meeting of the Intergovernmental Panel on Climate Change (IPCC).

"I'm not saying it's costless. I'm not saying climate policy is a free lunch. But it's a lunch worthwhile to buy," he said.
