The opposition leader Sir Keir Starmer has described the summit as a "missed opportunity", but acknowledges the agreement represents "modest progress" towards limiting global warming.

The Labour party leader says: "But we have seen too many promises for tomorrow, not the action that the climate emergency demands today."

"Glasgow has been a missed opportunity - a summit too often of climate delay not climate delivery".

Starmer also accuses Prime Minister Boris Johnson of not treating the climate summit with sufficient seriousness or building trust critical to its success, saying he "bears some responsibility" for the lack of action in the agreement.

Boris Johnson hasn't commented yet on the summit.

Alok Sharma just received a standing ovation as he spoke to the plenary, which is still meeting and discussing various parts of the agreement.

He thanked the many parties who have "sacrificed wording that you held dear for the sake of an agreement" and also those who "held their nerve" as tempers frayed.

“I think we can say we have kept 1.5 within reach, but its pulse is weak. It will only survive if we keep these promises," Sharma said.

He once again held back tears as he said: "History has been made here in Glasgow."

It's not over yet though. It's just gone past 21:00, but they still have things to discuss.

"We can't go for dinner yet," he quips.

It's safe to say Greta Thunberg is not impressed with the agreement - summarising its contents as "Blah, blah, blah" on Twitter.

She's used the phrase many times during this summit.

Glasgow Pact will keep hope alivepublished at 20:51 Greenwich Mean Time 13 November 2021

While the last-minute row over phasing down instead of phasing out coal will be seen to have weakened the agreement, the Glasgow Climate Pact is still an ambitious attempt to rein in rising temperatures.

The actual text of the final agreement is quite progressive, getting countries to come back again with strengthened plans next year.

There’s also a significant doubling of money to help poor countries adapt to the impacts of climate change – and the prospect of a trillion dollar a year fund from 2025.

The UK, as chair of the talks, encouraged countries to pledge new limits on deforestation, methane and coal that will have positive impacts if everyone lives up to their promises.

These are all significant steps – and they will help to bend the emissions curve which will rein in temperatures in the longer term.

But will they keep the world from warming by more than the critical threshold of 1.5C?

The atmosphere unfortunately responds to emissions and not decisions made in a conference. Glasgow will keep hope alive - but the real world impact of COP26 won't be known for several years.

Matt McGrath has been covering climate change for the past 15 years, reporting from 10 COPs along the way.

Environmental group Greenpeace is giving their verdict on the deal - and the last minute change to the wording on coal.

In case you missed it, an earlier commitment to "phase-out" coal was watered down and replaced with the wording "phase-down".

“They changed a word but they can’t change the signal coming out of this COP, that the era of coal is ending," says Greenpeace international executive director Jennifer Morgan.

“It’s in the interests of all countries, including those who still burn coal, to transition to clean renewable energy, and richer countries need to do more to support the shift. Our future depends on it.”

On Friday, Greenpeace used helium balloons to fly a sign reading "not for sale" over the massive COP Earth hanging from the venue ceiling.

UN Secretary-General António Guterres says the world must "go into emergency mode" on climate change, as the agreement does not go far enough.

However, he acknowledges it establishes "important building blocks for progress" and is a compromise reflecting the "interests, contradictions and state of political will" around the world.

In a message to young people, indigenous communities and other people at the forefront of climate change activism Guterres says: "I know you are disappointed, but the path of progress is not always a straight line.

"Sometimes there are detours, sometimes there are ditches. But I know we can get there."

Elizabeth Kité is an activist in Nuku'alofa,Tonga. I just called her to ask what she thinks of the deal. It doesn’t do enough to save her island home in the Pacific from one day drowning, she says.

She calls the summit a stage for big countries to “flex how much they can pay small nations”.

Elizabeth gets emotional describing her pride in watching how hard the Pacific Island negotiators worked in Glasgow.

“We are friendly people and we are usually very peaceful. It’s unnatural for us to come out so strong - and I’m sad the deal doesn’t reflect how hard we tried,” she explains.

But there is progress, she says. It’s the first time fossil fuels and coal have been included in COP texts. And she says the promise of proper dialogue around funding for loss and damage - money to help countries pay for climate impacts they can’t adapt to - is a big step forwards.

Global climate diplomacy laid barepublished at 20:16 Greenwich Mean Time 13 November 2021

It’s rare that we get to see climate diplomacy laid so bare.

But in the final stretch, a live video feed relayed in remarkable clarity how conference chair Alok Sharma shuttled between delegations.

Carrying a large notebook, he was first deep in discussion with the US envoy John Kerry before walking fast across the hall to the Chinese team.

After huddling over the text, their brief but animated conversation ended with nods and then it was back to the Americans and on to the EU delegation.

At one point in this flurry of negotiation, Sharma pulled his mask aside, presumably finding it easier to make a point.

Next stop: the team from India, notebook still in hand – he would return to them a few minutes later .

Amid bitter disappointment over the wording of phrase about the future of coal, Sharma's voice caught in his throat as he apologised for how the final deal was reached.

But, he reiterated, they were doing what they must to reach an agreement.

Well, that was a last minute twist - so what happened?

Countries have been wrangling over fine details all day - but in the final moments India and China both pushed to water down of the wording around coal.

The previous draft said countries would "phase out" the use of unabated coal - that's coal-burning which is carried out without some form of carbon capture and storage to counteract the emissions it produces.

But that wording has now been changed to "phase down".

The move prompted angry responses from European nations and several island states.

However, every party still agreed to the deal, as many said the overall package was better than no deal at all.

And as the gavel strikes the table, it’s official: the Glasgow Climate Pact has been agreed.

All 197 parties of the United Nations have signed up, despite strong reservation and disappointment voiced by many.

Alok Sharma chokes up as he says he is "deeply sorry" for the way this process has unfolded.

"I understand the deep disappointment. It's also vital we protect this package," he continues.

The Marshall Islands joins others in voicing "profound disappointment" with the change in the language on coal from "phase out" to "phase down".

The country is deeply threatened by sea level rises - it is a nation of more than 1,200 low-lying isles in the Pacific Ocean only 2m above sea level.

Tina Stege, the clmate envoy for the country, says they will accept the change with the "greatest reluctance" and only, she stresses, because there are critical elements of the deal that are a "lifeline" for her people's future.

The European Union "wanted to go even further" on moves to phase out coal power in the draft text, the body's negotiator Frans Timmermans says.

He describes the proposal by India to change the language of the agreement to call for the "phase-down" rather than the "phase-out" of dirty coal power as a "further disappointment".

"Because we know the longer you take to get rid of coal, the more burden you put on the natural environment, but also the more burden you put on your economy.

"Because coal is simply not a smart economic proposition either, that's why we want to speed up the exit."

But he said the wording change should not stop the world agreeing a deal in Glasgow, which would nonetheless represent a "historic decision".

Switzerland is expressing "profound disappointment" at last minute changes to the wording of the deal.

They say the language that has been agreed on for coal and fossil fuel subsidies has been "further watered down as the result of an untransparent process".

"Let us be clear: we do not need to phase down, but to phase out coal and fossil fuel subsidies," she says.

She adds Switzerland do not want to risk leaving Glasgow without an outcome - so have agreed to the new wording.

But she ends with a warning: "This will not bring us closer to 1.5C but make it more difficult to reach it."

The Indian delegate has just called for a change to the wording of the draft climate agreement.

He asks for the line to call for the "phase-down" not the "phase-out" of unabated coal power.

This would be a major change to the text.

The line around coal and fossil fuels is seen as unprecedented language in a COP agreement.

"It is now decision time," COP26 president Alok Sharma tells his colleagues as they gather for the final meeting.

The negotiations have been far from easy, he says, but adds: "Each and every one of you... has stepped up here in Glasgow."

He says the deal places an "unprecedented focus" on loss and damage - the principle that richer countries, which bear the main responsibility for the global warming, should pay compensation to poorer ones because of climate impacts.

And this is it, we've reached the final mile: we are going to find out whether the Glasgow Climate Pact will be officially agreed - or not.

COP26 president Alok Sharma is kicking off the formal plenary session now.

Remember - all 197 parties must agree to sign up to the deal.

Most countries have admitted the deal isn't perfect - each have their own priorities and concerns - but some have been more critical than others.

Stick with us as we bring you the latest.

Things have gone a bit chilly in the plenary room – and not just because the organisers are cutting down on the carbon heavy heating.

It’s rumoured that China has taken umbrage at the wording of the key passage on fossil fuels and coal.

The text currently calls for the phase out of unabated coal and inefficient fossil fuel subsidies.

Tempers are said to have frayed as China insisted on a change in a huddle with the US, UK and EU.

Apparently they want the phrase “phase-out” to be changed to “phase-down”.

The other big powers are set to go along with it.

Will it make a difference? That’s hard to say – but it clearly shows the clout of the world’s biggest emitter.

As we head into the final meeting of this summit - which could see the agreement approved and COP26 formally end - let's recap what is in the current draft.

Here are some of the most important bits:

• Firstly, it says that limiting global warming to 1.5C to avoid the worst impacts will require big emissions cuts, including net zero by 2050
• It includes an unprecedented call for the phasing out of "unabated coal power and inefficient fossil fuel subsidies" (Unabated coal is coal produced without the use of technology to capture the emitted carbon.)
• But it also recognises "the need for support towards a just transition" - which is something developing countries argued for, given the power needs of their growing economies
• Countries are asked to "revisit and strengthen" their 2030 emissions-cutting targets by the end of 2022, "taking into account different national circumstances"
• Developed countries are urged to at least double their collective provision of climate finance - to help developing nations adapt to climate change - from 2019 levels by 2025

This closing session could see any final objections or proposals for amendments before the text is passed and the final "gavel" banged.
