A last-minute fight over emissions-cutting and the overall climate change goal is delaying a potentially historic deal that would create a fund for compensating poor nations that are victims of extreme weather worsened by rich countries’ carbon pollution.

Iran PressAfrica: COP27 summit makes progress on funding for poorer countries but wrangling continues over the final agreement

By early morning Sunday, delegates at the United Nations’ climate conference in Egypt were still locked in negotiations, hours after the European Union and a coalition of more than 100 developing countries had come to a tentative agreement with outlines of a fund to help vulnerable countries deal with the consequences of climate change.

It was a development that could pave the way to a successful end to weeks of negotiations after the conference, known as COP27, had gone into overtime.

“We are extremely on overtime. There were some good spirits earlier today. I think more people are more frustrated about the lack of progress,” Norwegian climate change minister Espen Barth Eide.

He said it came down to getting tougher on fossil fuel emissions and retaining the goal of limiting warming to 1.5 degrees Celsius (2.7 degrees Fahrenheit) since pre-industrial times as was agreed in last year’s climate summit in Glasgow. 219
