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?
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!
