The promises arrived at a rapid clip over two weeks in Glasgow last year. There, along the banks of the River Clyde, leaders from nearly 200 nations vowed to do more – and move faster – to combat climate change.

They forged pacts to halt deforestation and cut emissions of methane, a powerful greenhouse gas. Rich nations agreed to spend more to help vulnerable countries adapt. And in recognition that the world is still moving too slowly, leaders pledged to “revisit and strengthen” their climate goals within a year if possible – a much tighter timeline than in the past.
