Yesterday afternoon, Hollywood actor Alec Baldwin spoke to BBC radio outlets from the conference in Paris.

He was here as a guest of the UN Development Programme, for whom he presented theEquator Prizes, external, which recognise "community efforts to reduce poverty, protect nature and strengthen resilience in the face of climate change".

Meanwhile, indigenous communities were protesting here at COP21 this morning. They want their human rights recognised in Article 2 of the Paris text, which sets out the long-term goal of the agreement.

Poor nations are winning their battle to get their vulnerability to climate change recognised.

They have long argued that the rather arbitrary 2C maximum temperature rise that’s been the UN benchmark for years was too dangerous for them.

"Climate vulnerable" nations, particularly island states facing the consequence of rising sea levels, have long campaigned for a target of 1.5C as a limit on warming.

The negotiating text already includes a target of holding temperature rise “well below” 2C - which is already a notional score for vulnerable nations, even though the pledges offered by all the countries here in Paris are nowhere near to delivering this.

And last night a facilitator told the conference that most countries were now willing to have the 1.5C figure also reflected in the final deal. 

It would be a victory for poor nations, but only in principle – we are inexorably heading for emissions that will produce a 1.5C rise. But if the climate gets nasty that 1.5 figure may be brandished as a legal weapon.

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

It is day 10 and the French hosts' Friday deadline is looming, as the conference president reiterated yesterday:

A new "clean" draft of the agreement text is expected this afternoon.

Environment correspondent Matt McGrath previews the day ahead:

Our live video Q&A has concluded - thank you for watching and contributing.

This COP21 live page will be back in action at 11:00 GMT on Wednesday 9 December, as the summit in Paris heads into its final days.

Environment ministers from around the world will be on the scene from Monday and the 40,000-strong conference will be up against a deadline.

Check back for the latest developments in the complex quest for a deal.

And in the meantime, listen back to BBC environment analyst Roger Harrabin's documentaries on Radio 4, "Changing Climate".

To finish, Matthew points to the oil jack behind him in Electra, Texas.

This is what brought oil to this town and started the boom, he explains. This is oil country.

But the boom is gone and the town is just emerging from a drought that had settled over the state for much of this century. And climate scientists predict longer, even hotter spells in the future.

Earlier, Matthew explained that many farmers in the area talk about the government 'regulating them out of business' by insisting that they adopt greener technologies.

Ian Jones comments: 

Matthew asks Dr Winguth about what can be done. "You're not going to stop Texans eating their steaks," he says.

Dr Winguth explains that there are attempts underway, by modifying farming methods and equipment, to reduce emissions in the beef industry. Once those measures are in place, he says, the carbon contribution from meat is "comparably small" compared with electricity generation.

Claudia Pingle asks:

We need to find a consensus, "even with the critics", Dr Winguth said, and take action.

Matthew describes a system in nearby Wichita Falls, which sees waste water no longer left to flow downstream, but processed and reused within the town instead.

Is sufficient being done to prepare for climate change compared with trying to stop?

Dr Winguth explains that fluctuations in CO2 in the atmosphere have occurred over the centuries and, if anything, we would expect even greater temperature change due to the carbon humans have put into the air.

The oceans appear to be the answer, he added - absorbing more than we had expected of the heat that the planet is accumulating.

@GilchristBlake tweets:

How did the Earth's climate change such as from the Ice Age to what we have today without human pollution?

Mr Lalk talks about what might - or might not - come out of the talks in Paris. If a deal is not reached, he says, there will be consequences.

He also says that people in the area have adapted to try to use systems that emit less carbon into the air.

Matthew talks to Trevor Lalk, a local farmer, about the grim forecasts for how the climate will change.

Once, Matthew explains as he drives through Electra, "This was really quite a thriving little town, built on oil."

But now, with oil prices falling, it has fallen on hard times.

Matthew asks Dr Winguth about the impact of the Paris climate summit.
