Former US vice president Al Gore has said he had a "productive" meeting with Donald Trump.
Mr Gore met the president-elect at Trump Tower and spoke briefly to reporters afterwards.
He categorised his meeting as a "sincere search for common ground".
Mr Gore also dubbed it "an extremely interesting conversation" but when asked what was discussed, he only said "to be continued" before leaving.
He said he also met Ivanka Trump, the president-elect's daughter.
Transition officials said earlier that the two would discuss climate change, which is Mr Gore's signature issue.
The president-elect called man-made climate change a hoax and has pledged to undo a number of regulations to protect the environment.
