Video: Greenpeace activists surprise commuters with Shard protest Crowds gathered and commuters stopped to take pictures of the protesters as they progressed up the 87-storey Shard tower in central London during rush hour this morning. The group are believed to have got on to the structure by climbing on to the roof of the adjacent London Bridge Station. The lead climbers are 'free-climbing', scaling the building without assistance, but are fixing safety ropes as they go. Greenpeace wants the area around the North Pole to be made a global sanctuary, off limits to industrialisation. More than three million people have backed their call at savethearctic.org.
