DAVOS, Switzerland, Jan 17 (Reuters) - U.S. climate envoy John Kerry said on Tuesday that time was running out for the world to tackle climate change and he was not convinced it would get to a low carbon economy in time to avoid the worst impacts for some of the most vulnerable people.

What was most needed to tackle climate change and to deliver a low carbon economy Kerry said was "money, money, money". (Reporting by Alexander Smith; Editing by Andrew Heavens)
