Everywhere she goes, people ask for selfies and tell her how wonderful she is. But what’s it really like to be the world’s most famous climate campaigner when you’re still a teenager? In this revelatory personal essay which she wrote for Swedish Radio, Greta Thunberg describes her journey to deliver a speech at the UN General Assembly, observing the effects of climate change first-hand, her encounters with both powerful and ordinary people and a terrifying trip in a yacht across the Atlantic.

This Swedish Radio production is introduced by Justin Rowlatt, the BBC's chief environment correspondent, and Greta's essay is interspersed with excerpts of her favourite music.
