GLASGOW -- The leaders of the U.S. and China, the world's two largest emitters of greenhouse gases, had strikingly different levels of visibility at the United Nations climate change conference here, but a similar message on one point: the need for action.
The Biden administration is "working overtime to show that our climate commitment is action, not words," the U.S. president told the 26th U.N. Climate Change Conference of the Parties (COP26), making a personal appearance at the summit.
