The world’s most famous climate activist has just turned 18 and is as uncompromising as ever.

In an extended interview, Justin Rowlatt asks Greta Thunberg how she intends to continue campaigning, now that she is back in school and living under lockdown at her family home in Stockholm.

Before the pandemic, the Swedish environmentalist had spent several months travelling around America in an electric vehicle lent to her by Arnold Schwarzenegger. A TV documentary crew shadowed her as she visited scientists, entrepreneurs and victims of wild fires, while also attending climate conferences and protesting.

She tells us what she learned, and why she believes the climate emergency is more dire than ever before.
