Can Biden woo the world on climate change?

President Biden hosts a virtual summit this week as the US seeks global climate action. But can he convince the rest of the world to go further and faster on cutting carbon emissions when the country has been out of the game for the past four years? Justin Rowlatt asks former US climate envoy Todd Stern and Isabel Hilton, founder of China dialogue. And, in a world where some countries are rolling back protections, can consensus still be found? We hear from the heart of the Brazilian rainforest, where the environmental police say they are losing the war against the loggers. Lisa Viscidi, director of the energy and climate change programme at the Inter-American Dialogue think-tank, says the summit provides an opportunity for Latin American countries.Photo: Climate protestors in Lyon, France hold up a sign saying 'SOS' (Credit: Getty).
