U.S is obstructing progress in the Climate Talks
European nations threaten to boycott U.S. climate talks
BALI, Indonesia (AP) -- Former Vice President Al Gore said Thursday the United States is "principally responsible" for blocking progress at U.N. climate conference.
Gore urged delegates at the conference to take urgent action to reduce emissions of greenhouse gases blamed for global warming.
"My own country, the United States, is principally responsible for obstructing progress here in Bali," he said. The United States has opposed including in a final conference document a suggestion that industrialized countries reduce emissions by between 25 percent and 40 percent by 2020.
European nations will boycott U.S.-led climate talks next month unless Washington accepts a range of numbers for negotiating deep reductions of global-warming emissions, Germany's environment minister said Thursday.
