Fabius said he remained on track to present a final agreement today, a day later than planned, that could be adopted by consensus among the almost 200 countries negotiating in the French capital.

The last stumbling blocks were over money, specifically how to structure hundreds of billions of dollars in funding from rich nations to poor ones to help them adapt to climate change.

Despite late-in-the game delays and a frustrating night of talks late on Thursday, many participants said the momentum towards an agreement was unlikely to be crushed at this stage.

"There are some very strongly held views but I also think there is a spirit of compromise," Australian Foreign Minister Julie Bishop said as talks moved to yesterday night, past the hour where Fabius had pledged to have the deal wrapped up.

The negotiators are trying to seal an agreement that would bind both rich and poor nations to cut rising greenhouse gas emissions.

UN Secretary-General Ban Ki-moon called a 27-page draft text on the table 'a good basis' for a deal to help avert more powerful storms, droughts, desertification and rising sea levels.
