Portugal Colonial - UN climate summit runs overtime as fury mounts on fossil fuels

The Emirati president of the COP28 summit had pressed the nearly 200 nations to reach an ambitious deal by the official end of talks at 11 am (0700 GMT), in an effort to force decisions.

But after another late night, there was no sign that the talks were anywhere near completion, with negotiators waiting for a fresh text after wide criticism of a draft released Monday.

"We have time and we are prepared to stay a little longer," German Foreign Minister Annalena Baerbock said.

The team from the Marshall Islands -- which lies on average 2.1 metres (seven feet) above sea level and is threatened with submersion as ice melts -- vowed to stay until the end.

The Pacific archipelago's negotiator, John Silk, said that his country "did not come here to sign our death warrant".

Cassie Flynn, global director of climate change at the UN Development Programme, said it was still possible to reach a deal that goes beyond the draft's "watery" language on fossil fuels.

"Parties are working around the clock," she said. "Negotiators are scurrying around rooms and on phone calls to try to find the places where they can agree."

- 'Broken beyond repair' -

Campaigners had hoped the COP28 summit -- set in a glitzy metropolis built on petrodollars -- would take the historic step of calling for the first time for a global phase-out of fossil fuels, which account for three-quarters of greenhouse gas emissions blamed for the planetary crisis.

But climate decisions must be made by consensus and Saudi Arabia, the world's largest oil exporter, has led opposition to the threat to its financial lifeblood.

The draft put forward by COP28 president Sultan Al Jaber -- himself head of the UAE's national oil company -- only lists a series of options including reductions in fossil fuel production and consumption.

Clive Hamilton, a professor at Australia's Charles Sturt University and veteran watcher of climate negotiations, said the "extraordinarily weak draft" showed the influence of the fossil fuel lobby, which showed up at COP28 in record numbers.

"If anything like the current text is adopted, it will show the COP process to be broken beyond repair," he said.

Scientists say the planet has already warmed by 1.2 degrees Celsius (2.2 Fahrenheit) from pre-industrial times and that 2023 -- marked by lethal disasters including wildfires across the world -- has likely been the warmest in 100,000 years.

The 2015 Paris summit endorsed an ambition of checking warming at 1.5 Celsius -- a goal endorsed in the latest draft, but which critics say is virtually impossible without serious efforts to curb oil, gas and coal.

"This is a war for survival," he said in a closed-door session which ended at around 2:30 am.

Kerry has supported calls to phase out fossil fuels, even though the United States remains the world's largest oil producer and much of the rival Republican Party adamantly opposes action on climate.

- Revisions expected -

Former US vice president Al Gore, who won the Nobel Peace Prize for his climate advocacy, said that the "obsequious" draft looked as if it had been written by the OPEC oil cartel.

Jaber acknowledged Monday there was work to do, and a person familiar with the COP28 presidency's thinking called Monday's text "an opening gambit" that could be built upon.

The 21-page text does not go so far as to demand action on fossil fuels, only presenting measures that nations "could" take.

"This is not a menu in a restaurant. We have to do all of these things," Canada's Steven Guilbeault, part of a group of ministers tasked by Jaber to shepherd negotiations, told AFP.
