At a UN summit held after tens of thousands rallied around the world, France promised $1 billion to the Green Climate Fund -- making it the only contributo rother than Germany to the new institution that would help the worst-hit countries.

It was the first such event since the Copenhagen summit on climate change ended in disarray in 2009 and aims to set the tone for a conference next year in Paris designed to seal a new global agreement.
