RIO DE JANEIRO — Diplomatic tensions over global warming spilt over into the G20 summit negotiations in Brazil this week, with sources saying the 20 major economies reached a fragile consensus on climate finance that had eluded UN talks in Azerbaijan.

Heads of state arrived in Rio de Janeiro on Sunday (Nov 17) for the G20 summit and will spend Monday and Tuesday addressing issues from poverty and hunger to the reform of global institutions. The talks must now also grapple with how to address escalating violence in Ukraine after a deadly Russian airstrike on Sunday.

Still, the ongoing UN climate talks have thrown a spotlight on their efforts to tackle global warming.

While the COP29 summit in Baku, Azerbaijan, is tasked with agreeing a goal to mobilise hundreds of billions of dollars for climate, leaders of the Group of 20 major economies half a world away in Rio are holding the purse strings.

G20 countries account for 85 per cent of the world's economy and are the largest contributors to multilateral development banks helping to steer climate finance.
