Climate change activists climb onto train's roof at London's Canary Wharf

Two climate change activists climbed onto the roof of a train at Canary Wharf's Docklands Light Railway station in London as part of a third day of action to pressure politicians to take more radical measures to protect the environment. A man dressed in a dark suit and a woman wearing a black coat stood on the roof of a train in the station holding a banner which read: "Climate Emergency. Act Now."
