The developing world has been asking for sharply more assistance from the rich nations that are responsible for the bulk of global warming over history. But those industrialized nations have been reluctant to make any promises.

Now Biden, who also attended last year’s conference in Scotland, will have a chance to showcase the progress his administration has made in the past year – and to cajole other countries to make similar efforts. Climate advocates say the Inflation Reduction Act will help deliver a boost to green industries that can outlast the Biden administration, helping to bypass some of the climate whiplash that comes from sharply different visions toward global warming from Democrats and Republicans.

Globally, many climate policymakers have welcomed the legislation, even if some have also said they still wished the United States would commit more toward helping other countries around the world. So Biden will address a largely friendly audience – potentially a respite after the midterms – while being confronted with demands to help the most vulnerable nations.

The trip to Sharm El Sheikh, Egypt, will be the first leg of a multination trip for Biden that is expected to include stops in Cambodia and Indonesia for major global summits, including the G20.

“The President’s travel is not confirmed,” White House spokesman Abdullah Hasan said in a statement.

Some U.S. officials did not expect Biden to travel to the climate conference because it starts just before November’s midterm elections and overlaps with the summits in Southeast Asia. The president also must return to Washington by Nov. 19 to attend his granddaughter’s wedding at the White House.

Officials involved in the talks said that a visit from the U.S. president would boost the talks and were a good sign for the prospects of a deal.

“I’ve been taught as a diplomat to only send your principal in when there is a deal to be clinched or a game-changing announcement to be made,” said one European diplomat, speaking on condition of anonymity to speak frankly about private reactions to the visit. “So if I’m then reversing that logic, deciding to send the principal must mean there is sufficient confidence that such a moment will emerge. This could be a very helpful move.”

The diplomat said that in the rhythm of these negotiations, smaller agreements along the way can help spur more ambitious deals in the end. at last year’s climate negotiations in Glasgow, for example, a side agreement between the United States and China to cooperate more on climate issues helped spur more ambitious final commitments.
