An anonymous reader writes: Negotiators at the UN climate talks in Paris released a draft of an agreement to reduce greenhouse-gas emissions. No part of the draft has been finalized as many points remain in contention, particularly between developing countries and more wealthy nations. Laurence Tubiana, the French envoy for the talks, said: "We could have been better, we could have been worse. The job is not done, we need to apply all intelligence, energy, willingness to compromise and all efforts to come to agreement. Nothing is decided until everything is decided."
