With negotiations on climate finance in Baku at a standstill, leaders are turning to the G20 meeting in Brazil for a breakthrough .

United Nations talks on getting money to curb and adapt to climate change resumed Monday with tempered hope that negotiators and ministers can work through disagreements and hammer out a deal after slow progress last week.

Heads of state arriving in Rio de Janeiro on Sunday for the G20 summit will spend Monday and Tuesday addressing issues from poverty and hunger to the reform of global institutions. Still, the ongoing U.N. climate talks have thrown a spotlight on their efforts to tackle global warming.
