G20 - little chance of deal in Copenhagen
European leaders voiced growing doubts on whether the world will meet a December deadline for a new climate deal as a summit here looked set to take up global warming in generalities.
Twenty leaders who represent 90 percent of the global economy were holding two days of talks in the eastern US city of Pittsburgh, itself billed as a model of transition from decaying steel town to a green technology hub.
The summit opened two days after a high-powered climate meet at the United Nations, where Japan and China offered new pledges on how to save the world from rising temperatures predicted to threaten entire species if unchecked.
But with just a little more than two months before a conference in Copenhagen -- designated two years ago as the venue to seal the successor to the landmark Kyoto Protocol -- pessimism was growing.
"When it comes to the negotiations, they are in fact slowing down; they are not going in the right direction," said Swedish Prime Minister Fredrik Reinfeldt, the current head of the European Union.
"We are very worried that we need to speed up the negotiations," he said.
German Chancellor Angela Merkel also sounded a sour note.
"There has been progress, in particular from the Chinese side, from the Japanese side now, and the UN meeting with (UN Secretary General) Ban Ki-moon," Merkel told reporters in Berlin before heading to Pittsburgh.
"But I have to say that when I consider what still has to be achieved before Copenhagen, we cannot be happy," she said.
