Biden says Trump's withdrawal from Paris climate pact put us "behind the eight ball"

President Biden told world leaders the U.S. is "back at the table" to join and lead the world in combating climate change, he said at the opening of COP26, the United Nations climate change conference in Glasgow, indirectly referring to his predecessor's withdrawal from the 2015 Paris climate pact. 

He went further in remarks shortly afterward, taking the unusual step of apologizing for Mr. Trump.

"I guess I shouldn't apologize, but I do apologize for the fact that the United States, in the last administration, pulled out of the Paris Accord and put us sort of behind the eight ball," he said at another opening day event.
