An official announced Friday morning that the deadline to submit the final draft of the climate change deal had been pushed back to Saturday.
The French host of UN talks aimed at saving mankind from climate catastrophe said Thursday a historic accord was "extremely close", but called for unprecedented compromises during a second night of non-stop negotiations.
Eleven days of bruising international diplomacy in the French capital have failed to resolve a host of decades-long arguments between rich and poor nations over how to cut greenhouse gas emissions that cause global warming.
But, with feuding negotiators from 195 nations heading into a second night of talks, Foreign Minister Laurent Fabius submitted a new draft of the planned accord and said it was time to take the "decisive step".
