Activists made a big statement in Paris as the Climate Summit heads into the weekend. A group of Greenpeace activists scaled the Arc de Triomphe, unfurling banners that called for François Hollande to "renew the energy." They also painted Place Charles de Gaulle into an image of the sun. Police forces were deployed and several activists were arrested. The climate change activists are campaigning for 100% renewable energy by 2050. [Additional reporting by The Associated Press and Storyful]
