Angry developing nations have warned that UN talks aimed at averting catastrophic climate change are at risk without a deal on the hot-button issue of financing.  Negotiators from 195 nations are haggling in Paris over the ingredients of a universal accord to slash greenhouse-gas emissions that trap the Sun's heat, warming the Earth's surface and oceans and disrupting its delicate climate system.  Taking effect from 2020, the pact would target emissions from fossil fuels such as coal, oil and gas - the backbone of the world's energy supply today - and channel hundreds of billions of dollars to vulnerable countries.  The question of finance to help developing countries make the shift to cleaner energy sources is "make or break", said South African negotiator Nozipho Mxakato-Diseko, who spoke on behalf of the G77 group of 134 developing and emerging countries including China, on Thursday.  "It has to be clearly understood that finance is critical," she told a news conference.  Gambia's environment minister, Pa Ousman, demanded money for poor nations to pay for the fallout of climate change events - known as loss and damage.  "If loss and damage is not addressed adequately, there will be no agreement in Paris," he said. "There is not going to be any other, second Paris. This is the time. This is the moment."  More than 150 world leaders including President Barack Obama launched the talks on Monday, seeking to build momentum for the tough negotiations ahead with lofty rhetoric about the urgency of the task.  But after three days of grinding discussions over a hugely complex 54-page draft pact, bureaucrats unveiled a document just four pages shorter and with vast stretches of text yet to be agreed.  "I don't see any translation of the rhetoric of the leaders of the world into working towards tangible outcomes in Paris. This is very, very dangerous," Tuvalu Prime Minister Enele Sosene Sopoaga said.  Ministers from around the globe will descend on Paris on Monday to try to transform the draft prepared by diplomats into a universal climate accord to avert planetary overheating. The conference is scheduled to conclude on December 11.  "At this rate, when ministers arrive next week they will wonder what progress has been made since world leaders took to the podium in Paris," said Greenpeace's head of international climate politics Martin Kaiser.  At the core of the talks is the goal of limiting average warming to a maximum of 2C over pre-Industrial Revolution levels.  Kaiser said long-term goals were now clearer in the draft, though it did not call for fossil fuels to be phased out by 2050 so as to limit warming to 1.5C - a more ambitious target being pushed by low-lying island nations at risk of sinking into rising seas.
Climate negotiators in Paris have revealed a draft deal after three days of talks, disappointing activists who say too little progress has been made.
