UN summit urges ambitious climate deal

UNITED NATIONS, New York – World leaders are urging ambitious action to combat climate change, but pledges remain well short of goals, with a year to go for an accord.

At a UN summit held after tens of thousands rallied around the world, France promised $US1billion ($F1.91b) to the Green Climate Fund — making it the only contributor other than Germany to the new institution that would help the worst-hit countries.

But UN Secretary-General Ban Ki-moon called the meeting more to build momentum than to reach concrete achievements. 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.
