OS Conversations: Climate change activists

President Biden opened a major global climate summit with a call to world leaders to step up to the challenge. Mr Biden committed the US to an ambitious target of halving emissions by 2030. We hear a conversation between three young climate activists in Indonesia, South Africa and Australia about what action they think is needed globally. And we discuss solutions with experts and hear messages from around the world about what steps people are prepared to take to fight climate change.

We get more accounts of the coronavirus pandemic in India --the country has recorded the highest-ever daily number of new cases. There’s an acute oxygen shortage and we hear from those who have been posting appeals for oxygen on social media and also speak to a doctor in Mumbai.

We’ll also return to Minneapolis where the funeral of Daunte Wright is taking place today. Mr Wright was killed by a police officer during a traffic stop earlier this month.
