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

At events at 265 cities in 43 countries 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 on September 18. 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.
