A climate change activist holds a birthday cake made from Danish pastries alongside a giant mask featuring U.S. President Barack Obama on the occasion of his 48th birthday, outside the White House in Washington, August 4, 2009. The protesters "celebrated" the President's 48th birthday by symbolically presenting a giant plane ticket for him to attend the December 2009 United Nations climate change conference in Denmark.
