As part of an estimated 100,000-strong demonstration, Greenpeace campaigners, activists and volunteers marched through Copenhagen on Saturday to the Bella Centre, site of the UN climate summit, demanding a fair, ambitious and legally binding agreement at the COP15 negotiations. This video by Michael Nagasaki captures some of the atmosphere of the event.

It's not just on this country that people get so riled about climate change that they're driven into taking drastic action, action such as, oh I don't know, climbing a chimney stack in a coal-fired power station.

A new series of videos from our Indian office (compiled into one above) showcases six activists who explain why they climbed the chimney at Kolaghat power station in October 2007 and spent a few days in jail after their arrest. Read more »

Bailing out the planet in Brussels © Eric de Mildt/Greenpeace

Hundreds of Greenpeace volunteers from 16 countries arrived in Brussels today and set up a barricade around the conference centre where EU finance ministers are meeting to discuss funding options to tackle climate change. Linking arms to block the exits, the volunteers were determined not to let the politicians out until they agreed a proposal to bail out the planet.

(Twitter was a-buzz with regular updates from the scene - look back over the #climateaction tag.)

Climate camp will be more urban this year, but it'll still be great.

Stuck for something to do? Here's a few ideas: You could go give Gordon a piece of your mind, attend a glamorous awards ceremony, or go camping in the glitziest part of town. Who says it's boring being an activist? (Certainly not me.) If you're spending too much time stuck indoors in need of some excitement, maybe it's time to get out and enjoy some fresh air, courtesy of this lovely trio of exciting upcoming events.

The nuclear industry has hitched a ride on the climate change bandwagon, proclaiming that nuclear power will solve the world's global warming and energy problems in one sweeping "nuclear renaissance."

As you might expect, there's a catch. Nuclear energy faces escalating capital costs, a radioactive waste backlog, security and insurance gaps, nuclear weapons proliferation, and expensive reactor decommissioning that will magnify the waste problem.

The dispossessed

In 1969, Marie Aimee took her two children for medical treatment, a six-day voyage across the Indian Ocean from their home on Diego Garcia island to Port Louis, Mauritius. Her husband, Dervillie Permal, stayed behind to work at a coconut oil factory and tend the family garden and animals.

After visiting the doctor and picking up supplies in Port Louis, Marie and her children arrived at the quay for the trip home. However, a British Government agent refused to allow them onto the boat, stranding Marie and her children in Mauritius. Throughout the following weeks, other marooned islanders appeared, congregating in a local slum, living in boxes or tin shacks. Two years later, Marie's husband arrived in Port Louis with one small bag and a chilling story.

An excellent film from The Ecologist exposing the tactics used against environmental protestors - from espionage and legal threats to news manipulation and violence:

Via Plane Stupid.

There's been more creative campaigning in the capital from anti-Heathrow expansion activists - this time, a message glowing softly in the dark for any evening strollers along London's South Bank to see.

'No 3rd Runway' has been written onto the side of an old, defunct barge on the Thames, just near the Oxo Tower, with tiny magnetic LEDs (like the ones shown in this Make Throwies Not Bombs video). It's yet another voice in the growing opposition to Heathrow expansion - along with the four mayoral candidates, a whole raft of organisations and, well, tens of thousands of you. Get involved!

With reflections on the roots of activism, environmentalism, and Greenpeace’s past, present, and future, here's Rex Weyler - author, photographer, ecologist, Greenpeace International co-founder and long-time trouble-maker.

When the first Greenpeace boat sailed across the Gulf of Alaska in 1971 toward the U.S. nuclear test site in the Aleutian Islands, the crew and their supporters in Canada had no idea that the campaign would launch a global organization. Irving Stowe, Quaker leader of the Don’t Make a Wave Committee that launched the campaign, belonged to a dozen such groups and believed that after a campaign the group should disband. His idea of keeping things simple and grassroots has merit, but as we know, that’s not how things turned out. Read more »

The guys at Biofuelwatch have been cooking up a week of protests around (what else?) biofuels. Like us, they're concerned about the rising demand for biodiesel etc and the implications that has for the climate, as well as deforestation, food prices and a host of other related issues.
