0900 CET As we left for the airport this morning, Ed Miliband was fighting on, as Gordon Brown said last night that he and the UK would, in search of a global climate deal.
The climate change secretary was speaking in support of the Copenhagen Accord in the plenary session of this extraordinarily bureaucratic UN COP15 meeting. There is still opposition from some African countries, the Small Island States and some Latin American countries. They're still talking, and who knows whether it will finally get nodded through, or not.
The EU position remains fuzzy. It was pushed aside as the final bit of paper emerged late last night.
A lot of people will try very hard to make this sound like an outcome worth having, a first step on a long, long road. What's for sure is that this is a mess, and not just as a climate deal. It's being described as "a collapse of the UN process", "the end of multilateralism".
In the end, those who were suspicious of the US parachuting in a fix seem to have got it the most right. The Copenhagen Accord reads like a US-inspired, weak, agreement.
America, China, India, Brazil and South Africa are signed up to something. But what the group of five cooked up became progressively enfeebled during the course of yesterday.
Crucially, there are no numbers on emissions cuts, and no mention of a legally-binding treaty.
All that remains of note in this political text is an acknowledgement that scientists say that the increase in global temperature "should be below" 2C. There is also a promise of $30bn in short term money for poor nations to help them to tackle the effects of climate change, and move to a low carbon economy.
The promise from the developed world to create a $100bn fund of long-term finance remains in the balance
Even an aspiration to cut global emissions in half (against 1990 levels) by 2050 was eventually taken out, apparently in response to pressure from China. And America got the tougher language it wanted on the checks and balances that measure international emissions - the "transparency".
The EU will carry on talking, and meet up in the first few months of next year, with Angela Merkel as host. They will try again, I understand, to attach numbers to promises of emissions cuts. Last night the text contained none of the annexes with these numbers. They were taken out when it became plain that the best that was on offer amounted to too little to meet the 2C goal.
China played a harder game than many expected, and in the end Angela Merkel held out against stepping up the European offer of a 20% cuts in emissions to 30%, dependent on an ambitious deal. People are also blaming Germany for the removal of language that might have led to a legally-binding outcome - eventually.
Now, officials are admitting privately that the chances of a legally-binding treaty, of any complexion, remain slim. So what of the Kyoto Protocol? The world is left with what to many is a vacuum; no global regime on climate change, no carbon price. It will be hard for business to be more than lukewarm about this outcome.
The UN talking shop will continue, in an effort to pick up the pieces. But many still appear to be in shock at what just happened in Copenhagen.
1300 CET Lunchtime now, and the United Nations talks have produced a Copenhagen Accord. In the end the climate summit, including grumpy EU delegates, agreed to "take note" of a pact shaped by five major nations - the US, China, India, South Africa and Brazil. It's being described as a flawed, but essential first step forward.
