Negotiators at this year's U.N. climate talks in Glasgow appeared to be backing away Friday from a call to end all use of coal and phase out fossil fuel subsidies completely, but gave poor countries hope for more financial support to cope with global warming.

The latest draft proposals from the meeting's chair called on countries to accelerate "the phaseout of unabated coal power and of inefficient subsidies for fossil fuels."

A previous draft Wednesday had been stronger, calling on countries to "accelerate the phasing out of coal and subsidies for fossil fuel."

While the chair's proposal is likely to undergo further negotiation at the talks, due to end Friday, the change in wording suggested a shift away from unconditional demands that some fossil fuel exporting nations have objected to.

U.S. climate envoy John Kerry said Washington backed the current wording. "We're not talking about eliminating" coal, he told fellow climate diplomats.

On government funds flowing into fossil fuels, Kerry said: "Those subsidies have to go."

"We're the largest oil and gas producer in the world and we have some of those subsidies," he said.

Kerry said it was "a definition of insanity" that trillions were being spent to subsidize fossil fuels worldwide. "We're allowing to feed the very problem we're here to try to cure. It doesn't make sense."

But there was a mixed response from activists and observers on how significant the addition of the words "unabated" and "inefficient" was.

Richie Merzian, a former Australian climate negotiator who directs the climate and energy program at the Australia Institute think tank, said the additional caveats were "enough that you can run a coal train through it."

Countries like Australia and India, the world's third-biggest emitter, have resisted calls to phase out coal any time soon.

Swedish climate activist Greta Thunberg told The Associated Press she feared that "as long as our main goal is to find loopholes and find excuses, not to take real action, then we will most likely not see any big results in this meeting."

Thunberg, who attended the start of the talks in Glasgow, spoke at her weekly protest outside Sweden's parliament Friday morning.

The question of how to address the continued use of fossil fuels responsible for much of global warming has been one of the key sticking points at the two-week talks.

Scientists agree it is necessary to end their use as soon as possible to meet the 2015 Paris accord's ambitious goal of capping global warming at 1.5 degrees Celsius (2.7 Fahrenheit). But explicitly including such a call in the overarching declaration is politically sensitive, including for countries, such as Saudi Arabia, that fear oil and gas may be targeted next.

Another crunch issue is the question of financial aid for poor countries to cope with climate change. Rich nations failed to provide them with $100 billion annually by 2020, as agreed, causing considerable anger among developing countries going into the talks.

The latest draft reflects those concerns, expressing "deep regret" that the $100 billion goal hasn't been met and urging rich countries to scale up their funding for poor nations to reduce emissions and adapt to climate change — an issue with which developed countries are also grappling.

It also proposes creating a fund to help poor countries tap existing sources of aid when they face the devastating impacts of climate change. But rich nations such as the United States, which have historically been the biggest source of human-caused greenhouse gas emissions, are opposed to any legal obligation to compensate poor countries.

Discussion on the issue, known as loss and damage, is likely to go to the wire, negotiators said.

Environmental campaigners expressed concerns about possible loopholes in agreements for international cooperation on emissions reduction, which includes the rules for carbon markets. Businesses are particularly keen to balance out excess emissions by paying others not to emit a similar amount.

"The invitation to greenwash through carbon offsetting risks making a farce of the Paris Agreement," said Louisa Casson of Greenpeace. "If this goes ahead, governments are giving big polluters a free pass to pollute under the guise of being 'carbon neutral', without actually having to reduce emissions."

Negotiators from almost 200 nations gathered in Glasgow on Oct. 31 amid dire warnings from leaders, activists and scientists that not enough is being done to curb global warming.

According to the proposed decision, countries plan to express "alarm and utmost concern" that human activities have already caused around 1.1C (2F) of global warming "and that impacts are already being felt in every region."

While the Paris accord calls for limiting temperature to "well below" 2C (3.6F), ideally no more than 1.5C, by the end of the century compared to pre-industrial times, the draft agreement notes that the lower threshold "would significantly reduce the risks and impacts of climate change" and resolves to aim for that target.

In doing so, it calls for the world to cut carbon dioxide emission by 45% in 2030 compared with 2010 levels, and to add no additional CO2 to the atmosphere by mid-century. So far the world is not on track for that, and developed countries are expected to be asked to submit more ambitious targets for cutting emissions next year.

U.N. Secretary-General Antonio Guterres told The Associated Press this week that the 1.5C-goal "is still in reach but on life support."

If negotiators are unable to reach agreement by Friday's official deadline, it is likely the talks will go into overtime. This has happened at many of the previous 25 meetings as consensus from all 197 countries is required to pass decisions.

The annual meetings, first held in 1995 and only skipped once last year due to the pandemic, are designed to get all countries to gradually ratchet up their efforts to curb global warming.

But for many vulnerable nations the process has been far too slow.

"We need to deliver and take action now," said Seve Paeniu, the finance minister of the Pacific island nation of Tuvalu. "It's a matter of life and survival for many of us."
