Soaring living costs cloud U.N. climate talks
U.N.-led climate talks began in Germany on Monday on a global warming pact, facing a challenge from critics who say climate measures are partly to blame for high food and energy prices.
The meeting is the second in a series of eight which aim to secure a global climate deal by the end of next year in Copenhagen, to come into force after the first round of the Kyoto Protocol expires in 2012.
