Indonesian activists display banners during a protest in Jakarta on November 4, 2009 to ask developing countries to reject the 15th Conference of Parties (COP 15).

But even the UN climate chief, Yvo de Boer, has said it will be impossible to reach a comprehensive treaty in Copenhagen, Denmark. Getty Images logo Getty Images 27 months ago
