Update 6 Jan 10: They've been released! Our four activists endured 20 days in a Copenhagen jail following a peaceful protest at the State Banquet for world leaders attending the UN climate summit. The four activists still face trial in the Danish courts, and possible prison sentences. You sent over 12,000 letters to the Danish Embassy in London during their detention - thank you so much for your support ensuring their release.

Four of our activists face the prospect of Christmas in jail this year over charges relating to a protest at the Heads of State dinner at the Copenhagen climate summit. But the leaders who did practically nothing about the greatest threat to our planet got away.

While we're waiting to hear the announcements from Copenhagen - here's a blow by blow account of what's happened at the Summit so far - written by Martin Lloyd, our climate communications manager:

With thousands of negotiators and hundreds of points to agree it may be impossible to come up with a comprehensive account of what happened. But I'll try and list some of the highlights.

At the start of the year the game-plan for success when it came to getting a fair, ambitious and binding agreement looked like this.

1. Rich countries needed to show they were serious by offering significant and guaranteed funds to support action by the developing world.

2. The developing world would then have the confidence to commit to action

3. Which would let Rich nations commit to stronger action

4. The handful of holdout nations would then face a world united for climate action

As the talks started, despite two years of negotiations there was almost no progress to report. Only a series of commitments from the developing world, all conditional on the rich countries coming up with the money.

So, what happened? Read more »

More than 50,000 people turned out on Saturday in London and Glasgow to tell our leaders we want tough action on climate change. Well done and a huge thanks to everyone who came out, painted themselves (and each other) blue and joined in the wave.

A few of the volunteers on the roof explain why they are taking direct action for the climate.

A cold Anna talks about the importance of still being on the roof in the morning.

Just a rough edit but gives you an idea of how our volunteers spent their night - looks cold.

Another day, another banner - a final message from Anna and Paulo from the roof of Parliament, before the protesters began to make their down on Monday evening.

High above the Venice lagoon, Greenpeace demand strong climate leadership. from the G8.

Just as our tired activists in Italy were starting to settle in for a long night on top of the coal power stations yesterday, we got word that Greenpeace climbers in the US had rappelled down the face of Mount Rushmore with a banner that challenges Obama to show real leadership on climate change at the G8 this week.

Note - the live broadcast is no longer running.

We need to see real action from world leaders this year if we are going to save our climate. That's why over 100 Greenpeace activists from 15 countries occupied four coal-fired power stations across Italy today and they're demanding that the G8 Heads of State take decisive leadership on climate change. You can follow live updates from the Italy here.

And now our friends in the US have climbed Mount Rushmore and are challenging President Obama to be a leader on climate change, and they are broadcasting it live. The signal drops out occasionally, but when it works - wow. The park authorities have just reach the top of the monument.

The UK can set an example for the world by putting an end to new dirty coal-fired power plants. Tell Ed Miliband what you'll do if he consents a new dirty coal plant at Kingsnorth in Kent: The Big If

Rich risks office ridicule to explain why he is not a typical Greenpeace fundraiser in his submission to our office blog relay, but he's big enough to handle it. Click here to catch up on the other entries to our office blog relay, a whistle-stop tour of Greenpeace staff here in the UK.

The Kingsnorth Six made history last year: accused of causing £30,000 of criminal damage to Kingsnorth power station, their defence of "lawful excuse"was accepted by the jury - because they were acting to safeguard property around the world "in immediate need of protection" from the impacts of climate change, caused in part by burning coal.

When I applied for a job at Greenpeace and was then actually offered the job I couldn't believe it. In fact I asked them if they'd phoned the wrong person. A week before I was due to start I got a phone call asking if I could come in a bit earlier on my first day. At 4am in fact. Oh, and I'd be dressing up as a puffin and would probably get arrested. And I wasn't allowed to tell anyone about this phone call!
