Colourful plastic animals representing Noah's Ark dot the Paris site of the UN climate summit, COP21 - clustered near several eating outlets and lining the so-called "Champs-Elysee" that runs between the huge halls.

Despite one very rainy day on Tuesday, the only flood this menagerie has had to face is the constant ebb and flow of conference attendees: negotiators, ministers, journalists, protesters, lobbyists and the myriad other people that make up COP21's 40,000-strong population.

The latest copy of the text will not be released until - at the earliest - 19:00 Paris time (19:00 GMT), the BBC has learned.

It is not clear whether there will be another round of the drafting process after that.

In the meantime, there is no shortage of activity around the Le Bourget site.

Former Archbishop of Canterbury Dr Rowan Williams addressed a press conference a little earlier - and now musician Sean Paul is speaking to journalists:

While the UN meeting in Paris heads towards its deadline, millions of migrant workers in Gulf states are increasingly worried they might have to leave if the region gets hotter due to global warming.

A formal meeting of the Conference of Parties (the main administrative body that convenes at meetings like COP21) is underway and handling decisions not relating to the Paris agreement text itself - such as reports from subsidiary bodies.

Delegates are filing into one of the big plenary rooms here in Le Bourget.

A fresh draft of the agreement text is expected during this afternoon.

Reverberations continue from our shock "go veggie" interview with The Terminator on Monday evening.

BBC Food has contacted us with these recipes so you too can protect the climate whilst building muscles like Arnie. Or not, as the case may be.

The president of France, Francois Hollande, said there were "still difficulties" as negotiators in Paris continue trying to secure a long-term deal on climate change - theoretically due at 6pm on Friday.

New versions of the draft text are expected in the coming hours as the representatives of almost 200 countries edge towards a compromise.

President Hollande said there were still problems over climate finance and this remains one of three key sticking points.

In drawing up their draft text, the French presidency have left open many options on the issue of cash, the demarcation between rich and poor and on the question of the long-term ambition of the deal.

There has been growing support for including a temperature rise limit of 1.5C from a wide alliance of countries, including the EU, African, Caribbean and Pacific Island states.

This so-called coalition of high ambition has now been boosted by the United States.

Securing a substantial agreement here will likely require this kind of broad based co-operation between rich and poor.

When asked by the BBC if there would be an agreement, Indian environment minister Prakash Javadekar said "it will happen, it will happen, God willing".

He did not elaborate further. His comment comes as a draft text for a deal is full of disagreements, mainly between developed and fast-emerging economies.

The formation of a new "high ambition coalition" with the US, EU and many countries from the developing world on board is being seen by some as another sign of deadlock between developed countries and fast-emerging economies like China and India.

Is it the calm before a storm or a measured build-up to a spectacular triumph of French diplomacy tomorrow? No one seems to know.

The place is buzzing with rumour and confusion.

Copenhagen-style collapse has long seemed unlikely but will the horse-trading over the text inevitably lead to a watering-down of the final document?

I am writing this in a lunch queue in which everyone has their heads down at their phones. Like me, they're waiting for news.

For a rundown of five key unanswered questions here at COP21, read Matt McGrath's blogpost, written in the wake of yesterday's draft.

He looks at:

1. What's it all about?
2. How do we get there?
3. Where's my money?
4. Can I trust you? And, perhaps most importantly...
5. When can I go home?

Some of the national negotiators are holding a press conference here at the moment.

There is still talk of a better, further revised draft text being released this afternoon - but no details on exactly what time, or what progress was made overnight.

Our science correspondent Rebecca Morelle, however, is beginning to detect the whistle of passing deadlines...

The document being hammered out here in Paris may be intended to protect the climate – but it will also formalise global shifts in politics and economics.

Debate used to be binary - rich vs poor, perpetrators of climate change vs victims.

Now it’s much more fluid, with developed and developing nations joining ranks on some issues, and developing nations in conflict among themselves.

The most vulnerable nations blame the rich for the problem, but also fear the rise in pollution from emerging nations like China, India and Brazil. The Americans partially agree – they say emerging economies must play a bigger role in curbing emissions and helping the most vulnerable states.

Emerging economies say the US can’t wriggle out of its historic pollution this way.

It’s not just posturing. These are deeply held views, and it’ll take some inspired drafting to enshrine fairness in a text which attempts to redefine the relationship between the history of emissions and the future.

Welcome back to the BBC's live coverage of COP21, the UN climate summit in Paris.

Parallel negotiations went through the night, with one session finishing at 04:00 local time and others even later.

These were closed-door negotiations and we are waiting to hear what state the agreement text is now in.

Last evening Laurent Fabius, the conference president, said he would convene ministers for an update in the early afternoon.

Stay with us for the latest updates.

With the UN climate talks set to end on Friday, there is a final push to reach a global deal.

With key issues yet to be resolved, further meetings have been scheduled for this afternoon.

Meanwhile, UN climate chief Christiana Figueres is calling for more finance for a fund that helps vulnerable communities in developing countries adapt to climate change.  

This live page will pick up again around 11:00 GMT.

On that note, we are concluding today's live coverage of COP21.

Once the plenary session finishes, negotiators and ministers will head into their parallel discussion rooms for the night.

This live page will pick up again at 11:00 GMT tomorrow, Thursday 10 December.

In the meantime, read this blogpost by our environment correspondent Matt McGrath, outlining "five unanswered questions" here at the talks.

And spare a thought for the delegates facing a very long night here in the Le Bourget conference centre.

In the brief meal break before they head into overnight meetings, they may well need an energy boost from a slice of conference cake...

While joining many other speakers in voicing enthusiastic thanks to Laurent Fabius for his - so far - very efficient presidency of COP21, the East Timorese representative went one step further.

If a Paris agreement is reached, he promised to support Mr Fabius's nomination for the 2016 Nobel Peace Prize.

Mr Fabius thanked him and added: "I was blushing for part of what you said, so hard that I can't recognise myself."

COP21 president Laurent Fabius has said he will now close the list of speakers; there are 10-15 countries remaining to take the floor in tonight's public session.

"After Tuvalu we will have had more than two hours of debate and I think all the points of view have been expressed," he said.

Mr Fabius said he is anxious that delegates get on with the business of further hammering out the text.

As the final few speakers take the floor, here's an overview of today's draft climate agreement from BBC science correspondent Rebecca Morelle, here in Paris:

Prakash Javadekar, India's lead negotiator, praised the INDC system of separate national climate pledges, calling it a "game-changer".

But he again called for greater support from the developed world:

Venzuela's Claudia Salerno said the Paris solution must not be one in which rich nations can "buy the right to pollute", but - like many other speakers - finished on an optimistic note, suggesting that an agreement will be reached.

Saudi Arabia's representative (pictured) questioned the way the text repeatedly requires action from those "in a position to do so"; what body will make that judgement?

Gurdial Singh Nijar of Malaysia, meanwhile, reiterated - in strong terms - his nation's concerns about "climate justice".

Despite everybody's desires to act, he said, "the world has not changed". And if the agreement does not ensure compensation for developing countries, "we will have no choice but to resist".
