The annual United Nations climate summit opens today in Lima, Peru. Diplomats from around the world are hoping to reach a draft agreement on a measure that would limit the greenhouse gas emissions that cause global warming. It would then be finalized at talks in Paris, France, next year. On the eve of the summit, activists from the group Greenpeace projected a message onto the historic Machu Picchu site calling for the use of renewable energy.

Martin Kaiser, Greenpeace climate chief: “Greenpeace is calling on the world leaders to transfer the energy system away from coal and oil towards a 100 percent renewable energy future by mid-century.”
