Greenpeace China kicked off a 10-month global warming campaign with two stunning projections on March 23, 2009. The aim of the campaign is to get Chinese President Hu Jintao and Hong Kong Chief Executive Donald Tsang to not only take aggressive measures at home to tackle global warming, but to also be global leaders at the UN climate talks that will be held in December in Copenhagen. The projections were done in Hong Kong and Beijing -- the latter being a countdown to Copenhagen projected onto historic Yong Ding Gate, originally constructed in 1553 and restored in 2005.
