This week will bring around 25,000 world leaders, business people, policy shapers and campaigners together in Glasgow for COP26, a global climate summit that’s seen as a crucial moment in the fight to curb global warming.

Among them will be young activists who in the last few years have made global headlines with the School Strike for Climate movement. Beginning with Greta Thunberg in Sweden in 2018, millions of young people have taken to the streets to try to get their voices heard.

We hear from three young people devoted to climate activism. In the Philippines, Mitzi Jonelle Tan grew up amid severe typhoons that would flood her bedroom. In India, Disha Ravi saw her grandparents struggle to get enough water for their farm. And in the United States, 19-year-old Jerome Foster has been invited to join President Biden’s Environmental Justice Advisory Council.

Do these young activists feel their voices are being heard? What action do they most want to see from world leaders at COP – and how realistic are their demands?

Presenters Kate Lamble and Jordan Dunbar talk to Disha Ravi, Mitzi Jonelle Tan, Jerome Foster and the BBC’s Environment Correspondent, Matt McGrath.
