The COP27 summit in Egypt wrapped up Sunday with a historic deal on funding to help the most climate-vulnerable countries cope with the devastating impacts of global warming.
However, the climate damages fund deal at the fraught U.N. climate summit saw its share of anger over a failure to push further ambition on cutting emissions.
The two-week talks in Egypt's Red Sea resort of Sharm el-Sheikh, which at times appeared to teeter on the brink of collapse, delivered a major breakthrough on a fund for climate "loss and damage."
Pakistani Climate Minister Sherry Rehman said COP27 "responded to the voices of the vulnerable, the damaged and the lost of the whole world."
"We have struggled for 30 years on this path, and today in Sharm el-Sheikh this journey has achieved its first positive milestone," she told the summit.
Tired delegates applauded when the loss and damage fund was adopted as the sun came up Sunday following almost two extra days of negotiations that went round-the-clock.
But jubilation over that achievement was countered by stern warnings.
U.N. chief Antonio Guterres said the U.N. climate talks had "taken an important step towards justice" with the loss and damage fund, but fell short in pushing for the urgent carbon-cutting needed to tackle global warming.
"Our planet is still in the emergency room," Guterres said. "We need to drastically reduce emissions now and this is an issue this COP did not address."
A final COP27 statement covering the broad array of the world's efforts to grapple with a warming planet held the line on the aspirational goal of limiting global warming to 1.5 degrees Celsius (34.7 degrees Fahrenheit) from pre-industrial levels.
It also included language on renewable energy for the first time, while reiterating previous calls to accelerate "efforts towards the phasedown of unabated coal power and phase-out of inefficient fossil fuel subsidies."
But that failed to go much further than a similar decision from last year's COP26 meeting in Glasgow on key issues around cutting planet-heating pollution.
European Commission Vice President Frans Timmermans said the EU was "disappointed," adding that more than 80 nations had backed a stronger emissions pledge.
"What we have in front of us is not enough of a step forward for people and planet," he said.
"It doesn't bring enough added efforts from major emitters to increase and accelerate their emission cuts," said Timmermans, who 24 hours earlier had threatened to walk out of the talks rather than getting a "bad result."
Britain's Alok Sharma, who chaired COP26 in Glasgow, said a passage on energy had been "weakened, in the final minutes."
Germany Foreign Minister Annalena Baerbock said she was frustrated that the emissions cut and fossil fuel phase-out were "stonewalled by a number of large emitters and oil producers."
Criticized by some delegations for a lack of transparency during negotiations, Egyptian Foreign Minister Sameh Shoukry, the COP27 chair, said any missteps were "certainly not intentional."
"I believe I succeeded in avoiding that any of the parties were to backslide," he said.
The deal on loss and damage – which had only barely made it onto the negotiation agenda – gathered critical momentum during the talks.
Developing nations relentlessly pushed for the fund, finally succeeding in getting the backing of wealthy polluters long fearful of open-ended liability.
A statement from the Alliance of Small Island States, comprised of islands whose very existence is threatened by sea level rise, said the loss and damage deal was "historic."
"The agreements made at COP27 are a win for our entire world," said Molwyn Joseph, of Antigua and Barbuda and chair of AOSIS.
"We have shown those who have felt neglected that we hear you, we see you, and we are giving you the respect and care you deserve."
With around 1.2C of warming so far, the world has seen a cascade of climate-driven extremes, shining a spotlight on the plight of developing countries faced with escalating disasters, as well as an energy and food price crisis and ballooning debt.
The World Bank estimated that devastating floods in Pakistan this year caused $30 billion in damage and economic loss.
The fund will be geared towards developing nations "that are particularly vulnerable to the adverse effects of climate change" – language that had been requested by the EU.
The Europeans had also wanted to broaden the funder base to cough up cash – code for China and other better-off emerging countries.
The final loss and damage text left many of the thornier questions to be dealt with by a transitional committee, which will report to next year's climate meeting in Dubai to get the funding operational.
Scientists say limiting warming to 1.5 degrees Celsius is a far safer guardrail against catastrophic climate impacts, with the world currently way off track and heading for around 2.5 degrees Celsius under current commitments and plans.
"The historic outcome on loss and damage at COP27 shows international cooperation is possible," said Mary Robinson, former president of Ireland and Chair of The Elders.
"Equally, the renewed commitment on the 1.5 degrees Celsius global warming limit was a source of relief. However, none of this changes the fact that the world remains on the brink of climate catastrophe."
