Before the world's leaders gather in New York for an international climate summit next week, a youth panel was held on Saturday. Swedish Greta Thunberg said only a few sentences that millions of people around the world have gathered to march - and that young people are unstoppable.

Secretary-General Antonio Gueterres said he is usually a keynote speaker, but this time he is a keynote speaker.

- One of the problems with world leaders is that they talk too much and listen too little, says Antonio Gueterres.

Prime Minister Stefan Löfven (S) and Minister of Climate and Environment Isabella Lövin (MP) will attend next week's meeting.
