On Monday, world leaders in Copenhagen rallied to congratulate Canada on its about-face: a new pledge to toughen carbon emissions and to commit $13 billion in aid to the developing world. But Environment Minister Jim Prentice was anything but pleased—turns out that the announcement was a fake, part of an elaborate stunt by the Yes Men activist group to shame Canadian leaders into reversing their lax stance on climate change. The high-level stunt involved fake websites of the Wall Street Journal, the United Nations, and Environment Canada. It also involved a fake press conference staged after fake negotiations. At one one of those conferences, Harper spokesman Dimitri Soudas was tricked into lashing out at the activists.
