Teenage climate activist Greta Thunberg will interview Sir David Attenborough on BBC radio.
Thunberg is guest editing the corporation's flagship radio news program; the Radio 4 "Today" show.
The interview will take place during a special climate edition on December 30 at 6 a.m.
The 16-year-old from Sweden said on Friday that it will be the first time she has met Attenborough in person.
Attenborough defended Thunberg's appearance at the UN Climate Summit in October amid criticism.
