On the 25th anniversary of the Exxon Valdez oil spill in Alaska, Greenpeace activists take action in Norway against an ExxonMobil oil rig scheduled to drill in the Russian Arctic. The activists protest against the West Alpha rig and are holding banners reading "No Arctic Oil." One activist is dressed in a polar bear costume. Greenpeace is calling for a ban on offshore oil drilling in the Arctic and for renewed efforts to fight climate change.
