Climate action 'bringing our countries closer together' -Biden

Biden called the meeting with dozens of heads of state to declare the United States back at the climate leadership table after his predecessor, former President Donald Trump, withdrew from the Paris Agreement to cut greenhouse gas emissions.

Biden also said he was "heartened" by a call by Russian President Vladimir Putin on Thursday for the world to collaborate on advanced carbon dioxide removal and that the United States looked forward to working with Russia and other countries on the technology.
