As we mentioned in our last pot, two-thirds of countries signed up to the UN climate convention need to be present for decisions to be made.

This is known as the “quorum”.

It has become a particularly pressing issue now that the group of small island nations known as AOSIS has walked out of the talks in protest.

And some countries will have to go home soon.

These conferences often come at great financial cost to poorer nations, so some may be unable to change their flights.

Remember the conference was meant to finish yesterday.

So eventually there’ll come a point where there aren’t enough countries left to reach a deal.

That is why time is running out.

We’ve now got sight of the agenda items for this plenary - it doesn’t include the draft agreement about cash or the Article 6 text that I just mentioned.

The other items are largely procedural UN issues that have to be gavelled at these meetings. It doesn’t look like this meeting will get the talks any closer to a deal.

But it could tell us which countries are still in Baku - two-thirds of countries who signed the UN climate convention must be here to pass a deal.

Once the meetings no longer has the required number, it is over.

We're hearing now from Marina Silva, Brazil's environment minister, who is addressing the meeting with the hosts at COP29.

She acknowledges that Brazil will be hosting the next COP, COP30, thanking Azerbaijan for their hospitality this year. Although, this is not an official handover.

Looking forward to the next climate summit, she says it is "fundamental" that we have an alignment within our countries on how best to move forward.

The sense of urgency and willingness to collaborate with each other is another alignment, the environment minister adds.

The COP29 president Mukhtar Babayev has urged the nations that are inside the plenary hall to "bridge the remaining divide" between countries.

"The eyes of the world are focused on us, however time is not on our side and I ask you to now step up your engagement with one another," he said.

A plenary has started - that's normally the final meeting where a deal is agreed.

But it would be extremely surprising if this was the final meeting, considering some nations have walked out and there is no agreement.

Instead this meeting is more likely to be about something called Article 6 - which is about carbon markets - but even that is controversial.

It's a risky strategy from the COP presidency.

This video I filmed on my phone gives you a sense of just how chaotic things are here now.

Adonia Ayebare, the chair of the G77+China group of developing nations had just left negotiations, pursued by a gaggle of journalists.

At one point he trips over, as his shoe comes off. At the end you can hear me trying my luck: “Sir will you be coming back to the talks?”

Nice try but he’s far too busy and keen to stay tight-lipped, for even a “no comment”.

I'm writing these posts in a back corridor in the maze-like COP venue, using a water fountain as a desk, as we await to hear from this year's hosts, Azerbaijan.

I was waiting to see if I could catch them to ask if these talks are over for good. But no luck.

Earlier my colleague Esme Stallard was sitting on the floor by the meeting rooms, surrounded by TV cameras and journalists.

It's chaotic for the diplomats here - but also for journalists, as we race around trying to find the latest updates.

The terms “developed” and “developing” crop up a lot in talks around climate cash – but what do they actually mean?

Essentially, “developed” means richer, industrialised countries, such as the UK and the US, and “developing” means poorer nations or emerging economies.

These classifications largely go back to the original UN Framework Convention on Climate Change in 1992.

They are important because they dictate which countries are obliged to contribute to climate finance.

There are currently 23 “developed” countries that have to contribute.

But many developed countries want to see this group expanded, arguing that the global landscape has shifted a lot since 1992.

China and the Gulf states, for example, are still classed as developing nations despite their increasing contributions to global warming.

This row is all about a new draft proposal. It’s not yet been published online but we’ve managed to get our hands on a copy.

The text is about how much money poor nations would get from richer ones to deal with climate change.

These are the changes, compared to the last draft text:

• It’s an increase of money, from $250bn to $300bn. But we know poor countries want closer to $500bn
• The text "encourages" developing nations to also give money - under the Paris Agreement 2015 only the richer nations should be giving money. We had already been told this is a major red line for many developing nations
• But developing nations may like that there is a commitment in there to triple the amount of money going specifically to protecting people from climate change. Historically most of the money has gone to just reducing greenhouse gas emissions.

What would it take for developing countries to accept this draft deal? Could increasing the amount of cash to $500bn be enough?

As we've said quite a few times now, it is manic here and I am conscious we have been throwing acronyms at you left, right and centre.

So a quick rundown of how these talks work.

All of the world's nations are present and are negotiating for the best outcome for their populations.

But power is in numbers.

So many countries get together and agree a common stance on something, and negotiate as a group.

And there are many different groups.

The European Union is one of them, but the largest and perhaps most powerful group here is one called the G77+China.

This the group of the world's developing nations, and it's now much bigger than 77 countries - but that's how many were in the group when it first started.

Another one is AOSIS - that's the group of small island countries.

They negotiate together as they have a common shared experience of being at the forefront of climate change particularly rising sea level.

The head of an influential group representing poorer countries says climate talks are continuing.

"Still locked in intense consultations," writes Evans Njewa, chair of the Least Developed Countries group, who is from Malawi.

On social media platform X he writes:

“We’re doing our utmost to build bridges with literally everyone," EU Climate Commissioner Wopke Hoekstra has said.

"It is not easy, neither on finance nor on mitigation. It is also a fair ask to stay constructive," he says.

This seems like a coded plea to those nations that we heard earlier were threatening to pull out to keep talking.

And it may be working.

We have heard from another delegate here that the EU is currently meeting with the COP president, the island states and the world's poorest nations - the Least Developed Countries group.

How serious is the collapse of these talks?

The sense here is that this is as bad as COP15 in Copenhagen, when talks famously ended without agreement.

That is as bad as it gets.

"The only time I can remember it happening was when the Africa Group did the same in Warsaw in 2013," Paoli says.

But she says the group did return to the talks, leading to a breakthrough.

"So walkouts have proven successful in the past," she adds.

Hundreds of people remain inside these wide, glaringly-bright halls.

Behind closed doors are the countries who have not walked out. Plus civil society observers who are allowed to watch UN meetings.

Every time someone walks out, a crowd of journalists with cameras chase after them.

Along with many others, I just ran at speed after a man in a suit flanked by security officers and press, thinking they might say something useful.

But it turns out it was someone from an NGO group, on his way to the toilet.

“Shame” shouted some climate campaigners, “pay up!” shouted others.

The object of their venom was John Podesta, who is the US climate envoy, and was being escorted from a meeting room in chaotic scenes here in Baku.

COP29 has taken a dramatic turn here this afternoon, with walkouts from developing countries from meetings with the Azerbaijani presidency over climate finance.

There was palpable anger among the least developed countries and island states that they were being messed around by richer nations.

They say that the financial offer being negotiated is insulting, they feel excluded and ignored.

In this atmosphere, campaigners turned on Podesta shouting that the US had sold out, and hadn’t paid their fair share.

Podesta seemed unperturbed, telling my colleague Justin Rowlatt that he hoped “this was the storm before the calm”.

In the middle of the chaos, I grabbed a veteran climate talks observer - Mohamed Adow, of Power Shift Africa.

I asked him why the least developed nations and AOSIS walked out?

He said it's because the latest draft deal is even weaker than past versions.

Adow says it no longer specifically requires rich nations to contribute to cash for tackling climate change. Instead, it says the money could come from any country.

"It’s a great escape effectively," he says.

Developing countries think this is the richer world running away from its responsibilities.

He accuses the US of being behind this.

"This is largely as a result of the fear of the incoming Donald Trump administration," he says.

Colombia's Environment Minister Susana Muhamad kept her cards close to her chest when I asked how she was feeling after the news that other developing countries might pull out.

Earlier this year Colombia hosted the UN biodiversity summit - very similar to COP but all about protecting the world's animals and plants.

So Muhamad is very experienced at handling tricky negotiations.

Clearly some of the countries here are trying to keep things calm, as all around me the world's press sprint from meeting room to meeting room in the hope of making sense of what is going on.

The clock has ticked past 18:00 local time - that means we're now running more than 24 hours past the original deadline for these talks to wrap up.

And it's now very unclear if there will be a deal at all...

COP29 is now teetering on the verge of collapse, observers are saying, after walkouts from negotiators from poorer countries struggling with the impacts of climate change and ongoing deep arguments over finance.

So what's gone wrong?

Developing countries are incensed that the richer world waited until very near the end of this COP to put a figure for climate support on the table.

They are also upset that the $250bn (£199bn) offer was so low – the G77 and China group of developing countries are now said to want public grants of $500bn per year.

Richer nations say this is impossible in the current economic circumstances.

Uniting all parties here is disdain for the Azerbaijani COP presidency – they are said to be weak and simply don’t have the experience or the clout to drive this gathering to a successful outcome.

All is not lost. Some observers believe the EU with small island states and the UK will have to wrest control of this meeting from the Azerbaijanis to turn it around.

But time is short.

“We are in a near-perilous state,” said one seasoned participant.

Dozens of protesters have been making their voices heard on the sidelines of COP29 today.

While many attendees have left the conference, some representatives from environmental and human rights groups remain.

Chanting "no deal is better than a bad deal", they are keen to put pressure on developing countries to push for more financial support from richer countries.

Here are a few of the groups we've seen:
