Planet-warming carbon dioxide emissions from oil, gas and coal rose to record highs this year, according to preliminary research from an international network of scientists at the Global Carbon Project.
The report came as leaders gathered in Azerbaijan for COP29 climate talks aimed at reaching a deal to boost funding for poorer nations so they can adapt to climate shocks and transition to cleaner energy.
The research found that to meet the Paris agreement's ambitious goal of limiting warming to 1.5 degrees Celsius, the world now needs to reach net-zero CO2 emissions by the late 2030s -- instead of 2050.
"This is what the presidency has been promoting since the beginning of this year -- the time window is narrowing, shrinking -- and we need to act urgently," Yalchin Rafiyev, Azerbaijan's lead negotiator for COP29, told AFP.
"There are still possibilities for keeping 1.5C within reach", and striking a deal on climate finance "will definitely pave the way for us to realise this opportunity".
The warning comes with growing concern about the future of global climate action after the election of Donald Trump, who has vowed to again pull the United States out of the Paris agreement after taking over the presidency in January.
Some leaders in Baku defended fossil fuels during two days of speeches, while others from countries plagued by climate disasters warned that they were running out of time.
Some of the strongest words came from Albanian Prime Minister Edi Rama, who complained that "our speeches full of good words about climate change, change nothing".
Rama skewered the many leaders who skipped this year's event, saying their absences added "insult to injury".
- 'Slower' path -
Italian Prime Minister Giorgia Meloni, meanwhile, urged a "realistic global outlook" that did not prioritise decarbonisation over "our production and social system's sustainability".
"We must protect nature, with man at its core. An approach that is too ideological and not pragmatic on this matter risks taking us off the road to success," the far-right leader said.
"Currently, there is no single alternative to fossil fuel supply."
And Greek Prime Minister Kyriakos Mitsotakis warned that countries "cannot drive ourselves into industrial oblivion".
Those views stood in sharp contrast to the line from countries beset by climate catastrophes and rising sea levels.
Tuvalu's Prime Minister Feleti Penitala Teo insisted that for Pacific island nations like his, "there is simply no time to waste".
He urged countries to "deliver a clear signal that the world is promptly phasing out fossil fuel".
- Money fight -
As leaders spoke, negotiators released a fresh draft deal on finance that includes a raft of options to raise funding but leaves unresolved sticking points that have long delayed an agreement.
Most developing countries favour an annual commitment from wealthy countries of at least $1.3 trillion.
This figure is more than 10 times the $100 billion annually that a small pool of developed countries -- among them the US, the EU and Japan -- currently pay.
Some donors are reluctant to promise large new amounts of public money from their budgets at a time when they face economic and political pressure at home.
They want instead to promise private sector mobilisation, an option NGOs describe as "wishful thinking".
"They always like to look at the private sector as the magic money tree," said Debbie Hillier, global climate policy lead for Mercy Corps.
US climate envoy John Podesta said a deal should include "new contributors" -- code for China, which is not labelled a developed nation despite being the world's second largest economy and largest polluter.
Already buried under debt, developing countries want new aid in the form of grants instead of loans.
Philip Davis, the prime minister of the Bahamas, which is vulnerable to hurricanes, said that small island nations have spent 18 times more on debt repayment than they have received in climate finance.
"The world has found the ability to finance wars, the ability to mobilise against pandemics," Davis said.
"Yet when it comes to addressing the most profound crisis of our time, the very survival of nations, where is that same ability?"
Nations far apart in COP29 climate finance talks
Baku (AFP) Nov 13, 2024 -
A fresh draft of a UN climate deal released Wednesday offers wide-ranging options to raise funding for poorer countries, signalling that tough negotiations remain at the COP29 talks in Baku.
Landing a new agreement to boost money for climate action in developing countries is the top priority of negotiators at the summit in Azerbaijan.
But it is deeply contentious, and consensus has eluded negotiators from nearly 200 nations for the better part of a year.
Most developing countries favour an annual commitment from wealthy countries of at least $1.3 trillion, according to the latest draft of the long-sought climate finance pact.
This figure is more than 10 times the $100 billion annually that a small pool of developed countries -- among them the United States, the European Union and Japan -- currently pay.
Some donors are reluctant to promise large new amounts of public money from their budgets at a time when they face economic and political pressure at home.
"It is their responsibility to convince their electorate," a key negotiator from a developing country told AFP.
An earlier version of the draft was rejected outright by developing countries, which considered the proposed terms weighted too heavily toward wealthy nations.
- Three options -
Fresh submissions were called, and the new document summarises three broad positions.
The first argues that rich, industrialised nations most responsible for climate change to date pay from their budgets.
The second option calls for other countries to share the burden, a key demand of developed countries, while the third puts forward a mix of the two.
A bloc of least-developed nations, mostly from Africa, are asking for $220 billion while small-island states at threat from rising seas want $39 billion.
Brazil's environment minister, Marina Silva, said "there is a convergence that these resources must be in the order of trillions" in public and private money.
Another Brazilian official, Andre Correa do Lago, criticised the negotiating tactics of richer nations.
"We think that the discussion was diverted by developed countries instead of responding as they should by the rules of negotiation that are taking place," he told reporters.
Friederike Roder from Global Citizen, a non-government organisation, said the draft proposes "more concrete options" for an agreement on a total amount and "specific objectives" for the poorest and most vulnerable nations.
"Unfortunately, this search for precision stops there. The proposals aimed at clearly defining what constitutes climate finance, and ensuring close and transparent monitoring, remain insufficient," she told AFP.
The latest 34-page draft reflects all the options on the table, said David Waskow, director at the World Resources Institute, a think tank.
"Negotiators now need to work to boil it down to some key decisions for the ministers to wrestle with next week," he said.
COP29 runs until November 22 but climate talks often run into overtime.
