DHAKA: UN Secretary General Ban Ki-moon and actor Leonardo di Caprio will join thousands in a march for climate action in New York on Sunday.

The Manhattan demonstration is part of a global protest, with over 2,000 marches taking place around the world.

Ban will also tackle the issue with 125 heads of state and government on Tuesday at UN headquarters.

It will be the first such gathering since the unsuccessful Copenhagen conference in 2009, reports BBC.

The meeting will attempt to push forward political momentum towards a new universal agreement on climate to be signed by all nations at the end of 2015.
