Mexico's President Felipe Calderon (L) shakes hands with India's Rajendra Kumar Pachauri, chairman of the Intergovernmental Panel on Climate Change (R), as Mexico's Environment Secretary Juan Elvira Quesada (background) looks on, after they take part in the opening of the Green Solutions @COP16 in Cancun December 5, 2010. The United Nations climate change talks in Cancun have far lower ambitions than last year's Copenhagen summit, which fell short of an all-encompassing deal to help slow floods, droughts, heatwaves and rising sea levels.
