Delegates at the annual U.N. climate summit in Baku are concerned about U.S. commitment to climate finance after Donald Trump's re-election. Developing countries are demanding up to $1 trillion in annual climate finance. The summit's negotiating priorities are competing against economic concerns, wars in Ukraine and Gaza, and Trump's climate-change denial. Azerbaijan, the host of COP29, will need to keep countries focused on agreeing to a new global finance target and transitioning away from fossil fuels. Before the talks can begin, countries must agree on an agenda, including China's proposal to address trade disputes related to carbon border tariffs.
