The agreement stipulated that countries come together every five years to update their climate action plans and nudge each other to do more. The goals of the summit are to have countries nudge each other to rein in their emissions, commit financial support to low-income countries to deal with the impacts, and iron out some of the rules of the Paris Agreement. “It was going to galvanize the raising of ambition on a global basis.” “Glasgow was never, ever going to get every country joining up in Glasgow or this year necessarily,” he said in a telephone interview Thursday. The United States climate envoy, John Kerry, who had recently described the summit as “the last best hope” last week tried to manage expectations. That is not within reach: Even if all countries achieve the targets they set for themselves at the 2015 Paris Agreement, average global temperatures are on track to rise by 2.7 degrees Celsius by the end of the century.
