Time ticks down for negotiators at COP29 to find deal to curb warming

With time running down, negotiators at the United Nations annual climate talks on Wednesday returned to the puzzle of finding an agreement to bring far more money for vulnerable nations to adapt than wealthier countries have shown they're willing to pay.

Pressure was building to drive a deal by the time COP29, as this year's summit is known, concludes this week. COP29 President Mukhtar Babayev asked negotiators to clear away the technical part of talks by Wednesday afternoon so they can focus on substance.

That substance is daunting. Vulnerable nations are seeking $1.3 trillion to deal with damage from climate change and to adapt to that change, including building out their own clean-energy systems. Experts agree that at least $1 trillion is called for, but both figures are far more than the developed world has so far offered.

Half the world away in Rio, Brazil, where the Group of 20 summit was wrapping up on Tuesday, the United Nations Secretary-General Antonio Guterres told the group of the world's largest economies that "the success of COP29 is largely in your hands."

"That goal, the financial goal, in its different layers, must meet the needs of developing countries, beginning with a significant increase in concessional public funds," he said.

And the president of Brazil, Luiz Inácio Lula da Silva, said developed nations should consider moving their 2050 emission goals forward to 2040 or 2045.

"The G20 is responsible for 80% of greenhouse effect emissions," he said. "Even if we are not walking the same speed, we can all take one more step."

Negotiators are fighting over three big parts of the issue: How big the numbers are, how much is grants or loans, and who pays. The "how big" question is the toughest to negotiate and will likely be resolved only after the first two are solved, COP29 lead negotiator Yalchin Rafiyev told The Associated Press in an interview Tuesday.

"There are interlinkages of the elements. That's why having one of them agreed could unlock the other one," Rafiyev said.

Alden Meyer of the European think tank E3G and veteran negotiations analyst summed up the state of negotiations on Wednesday by saying the word of the day at the talks is "circle… as in going around in circles."

"All presidencies must at this point show that they have what it takes to move from administration to leadership," German climate envoy Jennifer Morgan said. "They must set the expectation for ambitious outcomes across the board. ... It is now up to the presidency to ensure that we move at full speed towards a green future."

The current goal of $100 billion annually was set in 2009. Rich nations have so far been reluctant to offer a starting figure to replace that. Rafiyev said the conference presidency has sought to pressure them, telling them that the figure should be "fair and ambitious, corresponding to the needs and priorities of the world."

India's junior environment minister Kirti Vardhan Singh, who is at the Baku talks, said that "the Global South are bearing a huge financial burden."

"This is severely limiting our capacity to meet our developmental needs," he said.

The European Union is expected to finally offer a figure, likely ranging from $200 billion to $300 billion annually, Linda Kalcher, executive director of the think tank Strategic Perspectives, said Tuesday.

That wasn't enough for Debbie Hillier, climate policy lead for the humanitarian group Mercy Corps, who called it "wildly out of step with the needs of developing countries" and a failure by richer nations to live up to the agreement of the 2015 Paris climate talks.

"If $200-300 billion is indeed the ballpark for what developed countries will offer, then this is a betrayal — a betrayal of the communities around the world who, whilst least responsible for climate change, are bearing its most devastating consequences," she said.

Some wealthy nations were talking of loans that could be leveraged to attract other money — grants, more loans and private investment — to multiply the funds they can offer.

But poorer nations say they are already drowning in debt and most money should come in the form of grants.

"It is possible to find constructive, innovative solutions," said Denmark's climate minister Lars Aagaard. "But it requires trust."
