copenhagen

Erratic monsoons, the highest summer temperatures for 50 years, disrupted summer rainfall patterns - just some of the impacts of climate change which are threatening the Indian city of Delhi.

In this second Voices for Change video, Delhi born photographer Ishan Tankha describes how the weather in India has changed during his lifetime, and ponders the consequences for himself and his fellow citizens.

The Copenhagen Climate Change Summit this December represents the best chance we have of reaching a deal to reverse current emissions trends in time to prevent climate chaos.

This is the first in a series of videos, Voices for Change, which talks to some of those who're already suffering aroung the world as a result of climate change. We'll be publishing more in the weeks running up to Copenhagen.

While our leaders continue to talk about what's "politically possible," the world continues to warm and precious days go by. The latest science shows that runaway global warming is even closer than we feared. We can't continue to allow our leaders to sit back and play political games when our future is at stake.

That’s why on October 24th, Greenpeace is joining with 350.org and a broad coalition of groups to participate in an international day of action. Events are already planned in over 100 countries around the world. Some are big, some are small - but every single one of them is absolutely necessary.

After spending the night on top of the Palace of Westminster, all the Greenpeace volunteers who took our 'Change the politics, save the climate' message to the heart of our democracy have been arrested, and are now in various stages of the process of being bailed and released.

Talking to some of the activists who put their liberty at risk to demand that politicians get serious about tackling climate change, it’s obvious that they are not attention seeking troublemakers, as some in the media try to portray them. Over fifty people from all walks of life, nationalities, and aged from early 20s to over 70, felt compelled to take action. Reasonable people like you and me who perhaps a year ago wouldn't have considered climbing up there. Why? Because time to act is running out and our politicians, for all their fine words, are still stuck in their old ruts - essentially fiddling while Rome burns.

After spending the night on top of the Palace of Westminster, Greenpeace activists laid out a banner on the roof, visible to MPs returning for the new Parliamentary session. Its message "Change the politics, save the climate", is a reminder that time to act is running out, and that we desperately need politicians who are willing to rise above the dogmas of party politics and actively meet the greatest challenge of our time.

Update, Monday 7pm: after nearly 28 hours on top of the Palace of Westminster, the remaining 31 volunteers have been been taken into police custody after ending their protest peacefully. Thanks to everyone who's been supporting them!

Update, Monday am: 31 volunteers are still ocuppying the roof this morning, 24 came down last night and were arrested and all have been bailed to return.

Fifty-five Greenpeace volunteers scaled the walls of the Houses of Parliament and are now occupying the roof to call for a new style of politics in Britain, one capable of rising to meet the challenge of climate change.

Tomorrow MPs return from their summer break and the government's own Committee on Climate Change will publish a progress report on UK carbon emissions. They make it clear that Britain is not doing enough to meet its commitments, and insist that a "step change" in emissions cuts is needed. With just 60 days go until the critical climate summit in Copenhagen - which faces a very real chance of failure as things stand - Britain has yet to show true commitment to making the process a success. We need politicians who are thinking about the next generation, not just the next election.
