With Bali's biggest decision now made, the media pack has rushed off to file stories, source reaction, or get drunk on the beach. But the action here in plenary is not quite done.

In a meeting under the ‘Kyoto track', countries have just signed up to the kind of ambitious goals that were washed out of the main Bali declaration.

This decision affects all countries that have ratified Kyoto (most of the world other than the USA).  This includes Australia. For the first time, it expressed "strong support" for a goal of reducing rich country emissions by 25-40% by 2020, from a 1990 baseline.

A rolling post, updating the tortuous path towards a Bali agreement. Update 1: a tentative agreement that will be debated further, 8am tomorrow morning. Update 2 (the next morning): the agreement begins to unwind. Update 3: misprint in the text! Update 4: farce. Update 5: Shameful scenes - Yvo de Boer in tears. Update 6: Just when it seemed impossible, Bali roadmap agreed. Update 7: De Boer returns.

A sobering review of progress from the G77 and China, whose Chairman just complained bitterly about the pressure developing countries were coming under to make concessions.

Unspecified countries - probably the US and Canada, and possibly Japan as well - had threatened trade sanctions if the developing world refused to take on commitments to reduce or limit their emissions, Munir Akram told us.

Negotiators are hitting the pain barrier here in Bali, as they press on in search of an agreement after catching only a few hours' sleep last night.

But the rest of us have spent the day in the doldrums. Press conferences have been scheduled and cancelled, and any news that has percolated out has just been more of the same.

We're still fighting over the same issues. How ambitious will the roadmap be? What kind of commitments will developed and developing countries be negotiating over the next couple of years?

The next announcement is scheduled for an hour's time. We'll all turn up and wait for it to be postponed yet again. Who knows when this will end? I will be happy to get out of here before the sunrise tomorrow - but we could still be sitting around sometime tomorrow afternoon.

Last night, we reported on the bombshell proposal from US negotiators to give all countries targets, based on their levels of economic development.

Talks broke up acrimoniously at 3.30, with a plethora of counter-proposals on the table. As he left, Yvo de Boer pronounced himself ‘confident' about reaching agreement - but I think he was joking.

A late night update from the UN climate conference, where the US has thrown a hand grenade into the talks on the Bali roadmap.

It's close to 1am and the negotiators are still arguing about two main issues:

"My own country, the United States, is principally responsible for obstructing progress here in Bali," Al Gore told Bali this evening, to ecstatic applause, putting the blame for any failure to reach agreement firmly in the Bush administration's court.

But he told the people who applauded his words they had a choice. They could get cross with America, and risk derailing the Bali agreement, or they could skirt around the country, leaving a ‘blank space' in the Bali roadmap for a new administration to fill in.

There is growing evidence that the EU has threatened to boycott the US major economies process on climate change, "unless there is a substantive outcome" from Bali.

Bali is turning into an asymmetrical battle. The EU badly needs everyone to agree a deal, while the US only needs a few countries to object if it decides to derail the negotiations.

But an EU boycott of US-sponsored talks would be a major slap in the face for the Bush administration. It represents one of the few negotiating cards the EU holds at these talks.

The story has been circulating since yesterday evening, when the French environment minister was said to have had an acrimonious meeting with Paula Dobriansky, head of the US delegation.

Some of the sticking points here in Bali are incredibly trivial and technical.

There's been a collapse on capacity building, for example, where the US has blocked progress on the deal that is on the table.

What's going on here?

The aim is to provide money for developing country governments to participate fully in negotiations, but the US has blocked agreement on the issue.

Two slightly different accounts of why.

According to the UN's Yvo de Boer, the US has said that it wants capacity building to be linked to developing country effectiveness in reporting its progress on tackling climate change. If they do a good job, they get money to invest in expertise.

"I am very concerned by the pace of things," was Yvo de Boer's sobering assessment of the state of play at lunchtime today.

De Boer is worried that so many issues are now linked that the ‘whole house of cards could fall to pieces' as the negotiations get frenzied over the next couple of days. There's also a chance that inadequate logistics could play a role...

The Europeans don't like the message they're getting from the Americans that the IPCC goal of a 25-40% target is based on insufficient evidence to be a useful guide.

"We don't need new studies and research," the German Environment Minister, Sigmar Gabriel. "If we ask the scientists, they're just going to tell us the same thing. We have to reduce 25-40% in developed countries if we want to be on target for 2050.

"It's not a question of known science. It's a question of mathematics. These questions of mathematics are clear since the Egyptians taught us to count."

"We want to launch a process that is open and does not predetermine or preclude options."

This innocuous phrase represents the key fault line here in Bali - symbolising an ongoing tussle between the Europeans and North Americans.

It represents US willingness to talk about a deal, but only if concrete numbers are stripped out of the Bali declaration.

A downbeat mood in Bali today, where there is shock at the attack on the United Nations in Algeria. The ‘high-level segment' of the conference has just started with a minute's silence. Security has been stepped up a notch, delegates are back in suits, and Ministers and heads of state fill the plenary room.

UN Secretary General, Ban-Ki Moon starts proceedings by condemning the ‘outrageous' attack to the media throng here in Bali. UN staff, who served the ‘highest ideals of humanity', and innocent bystanders have died in a cowardly act, he says. Innocent civilians have also been murdered.

Sir Nicholas Stern - these days a minor deity in the international firmament - spoke at a debate this evening on the new UNDP report on climate change and development.

Stern (whose name is invoked an average of 3,421 times an hour around the Bali conference centre) has become an unrivalled oracle for what climate change will cost, both if fixed and if left unchecked.

But one fact seldom noted is that his report focuses on keeping greenhouse gases below a level of 550ppm - a target that now looks quite dated, with most commentators talking about 450ppm or even lower.

This afternoon saw a sparky press conference from the Brazilian foreign minister, Celso Luiz Nunes Amorim.

Amorim represented Brazil at the weekend's talk on trade and climate, where he found himself in a public spat with the US trade rep over the exclusion of biofuels from a proposal to cut tariffs on environmental products.

The move is rank protectionism, he told me, and is still furious about the rejection of what he regards one of the few proven technologies for lowering carbon emissions.

Today sees a new tactic here at Bali - free massages. Yes, the Committee for a Constructive Tomorrow (CFACT) are helping members of the media ‘relax, unwind and chill out' with a massage and booze on tap.

Presumably, CFACT will use the opportunity to warn journalists about the scientists, media and politicians that they accuse of hyping climate change for personal gain. Or will such 'special services' require an additional payment?
