Greenpeace activists show their support for the Arctic 30 at the COP19 'Climate Justice' march in Warsaw.

At events across the world, thousands of people take part in a day of solidarity to mark two months since the Arctic 30 were detained following a peaceful protest against Arctic oil drilling. A Russian court has charged the Arctic 30 (twenty-eight Greenpeace International activists, as well as a freelance videographer and photographer) with both piracy and hooliganism.
