U.N. climate talks in Bangkok will end Friday without progress on the pressing issues of emission targets for rich countries and financing for poor nations, who insist they will not sign a global warming deal unless those matters are resolved, AP reported. For months, negotiations have been deadlocked and delegates have begun raising doubts whether a new climate pact to rein in greenhouse gases can be reached by the time world leaders gather in Copenhagen in December. The pact would replace the Kyoto Protocol which expires in 2012. Rather than addressing the tough issues, U.N. climate chief Yvo de Boer said late Thursday that the failure by rich countries to agree on ambitious emission cuts and billions of dollars in financing to help poor countries adapt to climate change has increased the distrust between the two sides. Even before the talks ended Friday afternoon, environmentalists including the World Wildlife Fund and Greenpeace were already criticizing governments for leaving the fundamental issues to future meetings in Barcelona next month. -- SPA
