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.
