LE BOURGET, France — After almost two weeks of marathon negotiations, the lines for food and coffee on Friday night snaked through the temporary tent city here that has been home to the global climate talks. People made final bets in a five-euro pool on the precise hour the talks might conclude.

Others, needing to recharge for the final stretch of negotiations, jockeyed for spots on couches in the lounges.

The goal here is a daunting one: to get 195 countries plus the European Union to agree, for the first time, on a deal that would start reducing the risks of climate change by cutting their use of fossil fuels that create dangerous greenhouse gas emissions.

Early Saturday morning, United Nations officials said they had reached agreement overnight on new language for the final draft of the pact, which would be released publicly at 11:30 a.m. Paris time. The officials also said that the French foreign minister, Laurent Fabius, hoped to bring that text up for a final approval by Saturday afternoon.
