US Special Envoy for Climate, John Kerry, makes a strong case for the G20 countries to see it as a responsibility to provide funding for developing countries to deal with climate change.

Since last week, African leaders led by President Akufo-Addo have taken a swipe at the G20 countries for reneging on their promise to help Africa and other developing countries fight climate change.

Some 100 billion dollars promised these countries annually to support their climate change efforts have not been honoured.

Former US Secretary of State John Kerry added his voice to calls for the developed nations to prove their commitment to the climate change discussion.

He says they emit more and so it is only fair they support. He was speaking at the UN Climate and Clean Air Coalition.
