During last month’s major climate-change summit at the United Nations, the Yes Men, above left, and associates distributed fake copies of the New York Post, intended to draw attention to global warming and the need to stop it. Below right, police officers confiscated the bogus Posts in Midtown near the offices of the paper’s News Corporation. The subject of a new “mockumentary” with a serious message about global warming — “The Yes Men Fix the World” — the “gonzo political activists” also were involved in producing a fake issue of The New York Times that was distributed last year.
