BAKU, Azerbaijan (AP) — The United Nations climate talks neared the end of their first week on Saturday with negotiators still at work on how much wealthier nations will pay for developing countries to adapt to planetary warming. Meanwhile, activists planned actions on what is traditionally their biggest protest day during the two-week talks.

The demonstration in Baku, Azerbaijan is expected to be echoed at sites around the world in a global “day of action†for climate justice that's become an annual event.

Negotiators at COP29, as the talks are known, will return to a hoped-for deal that might be worth to poorer nations. Many are in the the costly impacts of . Several experts have said $1 trillion a year or more is needed both to compensate for such damages and to pay for a clean-energy transition that most countries can't afford on their own.

The talks Friday. Two former top U.N. officials signed a letter that suggested the process needs to shift from negotiation to implementation. And others, including former U.S. Vice President Al Gore, criticized the looming presence of the fossil fuel industry and fossil-fuel-reliant nations in the talks. One analysis found at least 1,770 people with fossil fuel ties on the attendees list for the Baku talks.

The conference’s chief negotiator, Yalchin Rafiyev, acknowledged that talks for a deal were proceeding too slowly, but pushed back on the criticism.

“The process has already delivered, the COP process so far, by reducing projected warming, delivering finance to those in need,†Rafiev said. “It’s better than any alternative.â€

Progress may get a boost as many nations' ministers, whose approval is necessary for whatever negotiators do, arrive in the second week.
