Early in the morning, the UK's presidency of this climate conference issued a new draft final declaration, but the afternoon plenary session highlighted the still significant differences among the 200 or so signatory countries of the Paris agreement in 2016.

The world is still heading towards a "catastrophic" warming of + 2.7 ° C, according to the UN, despite the new commitments for the 2030 deadline announced just before and since the start of the COP.

One of the most disputed points: the financial envelope to help the poorest countries - the least responsible for climate change but on the front line in the face of its impacts - to reduce their emissions and to prepare to face storms, heat waves and increasing droughts.

"We must put the money on the table to help developing countries make the necessary changes (...) This is what must happen in the coming hours," Boris Johnson insisted on the BBC Friday after -midday.

Before the conference he had made "cash" one of his priorities.

"We will not be able to have everything at the COP, but we can start," he added, seeming less optimistic than before the start of this conference to achieve its proclaimed goal of "keeping 1.5 ° C alive. ".

"Broken trust"

In 2009, the countries of the North had promised to increase their climate aid in the South to 100 billion per year from 2020.

But the promise is still not kept, sharpening the resentment of developing countries amid a health crisis that adds to their burden.

The draft declaration calls on rich countries to fulfill, and even go beyond, their broken promises.

And to double by 2025 the aid specifically devoted to adaptation to the effects of climate change, while it is the financing of emission reductions that captures 75% of the total.

But these commitments are not enough, insist the developing countries.

"Our confidence has been shattered", notably underlined the representative of Kenya.

The poorest, who account for an insignificant share of global emissions, also insist that financing take into account the "loss and damage" they are already suffering at an increasingly frequent rate.

But on this point, the draft declaration just proposes to speed up the implementation of measures already planned, without quantified targets over time.

"We are extremely disappointed" that the proposal for a specific device was not retained, launched the Guinean representative on behalf of the G77 + China group (more than 100 developing and emerging countries).

"We want to see our proposal in the text," he insisted, especially "since it was made by the entire developing world", including large emerging countries.

Madness

All envelopes combined, the estimates of the financing needs of the groups of less developed countries now range from 750 billion to 1.300 billion dollars per year.

A range confirmed by a draft IPCC report obtained by AFP.

Another burning issue at the heart of the negotiations which were to officially end at 6:00 p.m. GMT, but which unsurprisingly fall into the extensions, fossil fuels, the main responsible for global warming.

While the Paris agreement did not mention fossil fuels, the latest draft declaration provides for the inclusion - softened compared to the first version - of the exit from their funding.

A mention supported in particular by the EU and the United States.

The American envoy John Kerry even lambasted the massive subsidies to these energies which are "the very definition of madness".

More generally, in an attempt to limit warming, the provisional text of the British Presidency calls on member states to raise their emission reduction commitments more regularly than provided for in the Paris agreement, starting in 2022. Even if the possibility of adjustments for "special national circumstances" has been added.

But while the 2015 climate pact calls for signatories to step up their ambitions every five years - with the next review slated for 2025 - some countries oppose what they see as a "rewrite" of the OK.

"We are not going to be able to stop the warming in Glasgow, we have to accept it, but we can keep alive the prospect of limiting the increase in the temperature of the planet to + 1.5 ° C by the end of the century, ”commented Boris Johnson.

While every tenth of a degree multiplies the extreme events, "it is much better than (...) + 2 ° C or more".
