Tens of thousands stage world's largest climate march in Copenhagen

Tens of thousands of climate activists marched in Copenhagen yesterday as part of a worldwide "Day of Action" to urge negotiators at UN talks to agree a strong treaty to fight global warming.

The rally was mostly held in a carnival atmosphere, but riot police detained about 900 activists at the rear of the march after bottles were thrown and a window at the Danish foreign ministry was smashed. The activists were forced to sit down on the street, with hands tied behind their backs.

The number of people on the march was estimated at 25,000 by police and up to 100,000 by organisers. Banners read, "There is no planet B", and "Change the politics, not the climate". Some activists dressed as polar bears and penguins with signs reading: "Save the Humans!" Some held a giant inflatable snowman under threat of melting from warming caused by burning fossil fuels, writes The Independent.
