Negotiators from 195 nations delivered a blueprint Saturday for a pact to save mankind from disastrous global warming, raising hopes that decades of arguments will finally end with a historic agreement in Paris.
The planned deal would aim to break the world's dependence on fossil fuels for energy, slashing the greenhouse gas emissions from burning oil, coal & gas that are causing temperatures to rise dangerously.
Tortuous UN negotiations dating back to the early 1990s have failed to forge unity between rich & poor nations, & the Paris talks are being described as the "last, best chance" to save mankind.
They began on Monday with a record-breaking gathering of 150 world leaders who sought to energise the process, & the next crucial phase ended Saturday with the adoption of a draft text of an agreement.
Negotiators finalised the draft following an often tense week of talks at a conference centre in Le Bourget on the northern outskirts of Paris.
And while many extremely contentious points still have to be resolved by ministers during a scheduled five days of talks starting Monday, delegates said they felt the foundations had been laid for success.
"We are very pleased to have this progress. The political will is there from all parties," China's chief climate envoy, Su Wei, told reporters.
After the draft was adopted to loud applause, South African negotiator Nozipho Mxakato-Diseko drew on her nation's revered democracy icon in a bid to inspire others.
"In the words of Nelson Mandela, it always seems impossible until it is done," she said.
– Exciting time in history –
More than 50 personalities committed to fighting climate change, from US actor Sean Penn to Chinese internet tycoon Jack Ma, moreover gathered at the conference Saturday to assist build momentum.
"Perhaps this is the most thrilling time in human history," Penn told a special event at the conference.
"Those illusions of having too many difficult choices have always created chaos. Now we live in a time where there are no choices. We have certainty."
Scientists warn our planet will become increasingly hostile for mankind as it warms, with rising sea levels that will consume islands & populated coastal areas, as well as catastrophic storms & severe droughts.
Small island nations most vulnerable to rising sea levels & stronger storms, which are often railroaded by the powerful in the UN talks, moreover expressed cautious optimism approximately the draft agreement.
"We would have wished to be further along than we are at this point, yet the text being forwarded so far reflects our key priorities," said Thoriq Ibrahim from the Maldives & chair of the Alliance of Small Island States.
– No guarantees –
But no one in Le Bourget is under the illusion that a December 11 deal is guaranteed.
"Let's be frank: all the difficult political issues remain unresolved," European Climate & Energy Commissioner Miguel Arias Canete said. "Next week is the week of compromise."
Greenpeace climate expert Martin Kaiser said there was cause for some optimism after feuding sides had showed some willingness to compromise.
"But that doesn't guarantee a decent deal. Right now the oil-producing nations & the fossil fuel industry will be plotting how to crash these talks," he said.
One of the reasons for optimism in Paris has been the submission by most countries of voluntary plans to curb their emissions from 2020, when the pact would come into force.
Scientists say these pledges, if fulfilled, would still fall far short of what is needed to cap warming at 2.0 degrees Celsius (3.6 degrees Fahrenheit) below pre-Industrial Revolution levels.
But the United States, China, India & some of the other biggest polluting nations want to enshrine 2 degrees C as the goal, which would allow them to emit more gases for longer.
Money has long been one of the biggest sticking points in the UN negotiations, & it remains so in Paris.
Poorer countries are demanding finance to pay for the costly shift to renewable technologies, as well as to cope with the impact of climate change.
At stake is hundreds of billions of dollars that would need to start flowing from 2020. But developing nations are complaining that rich countries are refusing to honour previous commitments to mobilise the cash.
