Thousands march in the host city Belem calling for stronger climate action

Thousands of people have marched through the streets of Belém, Brazil, demanding stronger action to confront global warming as the UN climate summit reaches its halfway point.

Also in today’s programme: we speak with a Ukrainian opposition MP about a major corruption scandal engulfing the country’s energy sector, which is regularly targeted by Russia; and we ask why the Icelandic language is under threat. We speak to the country’s former prime minister.

Presenter Julian Worricker is joined by Karin von Hippel, defence and security analyst, and Timothy Garton Ash, British historian and author. He is Professor of European Studies at St Antony’s College, University of Oxford.
