If Russia invades Ukraine, what could happen to natural gas supplies to Europe?

As frantic diplomatic efforts continue to avert a Russian invasion of Ukraine, Europe’s reliance on Russian gas supplies – and what would happen to them in the case of a war – remains an ever-present threat.

We speak to two experts on the geopolitics of natural gas about the history of the energy relationship between Russia and Europe, and the role gas supplies play in the current diplomatic efforts to avoid war. Featuring Michael Bradshaw, professor of global Energy at Warwick Business School at University of Warwick in the UK and Anastasiya Shapochkina politics lecturer at Sciences Po in France.

And, the Beijing winter Olympics are the first games to use 100% artificial snow. We talk to a Madeleine Orr, lecturer in sport ecology at Loughborough University in the UK about what that might mean for the athletes – and for the environment around the Olympic sites. (Listen from 30m30)

Plus, Haley Lewis for The Conversation in the Canadian capital Ottawa recommends some recent analysis of protests by truckers against COVID-19 restrictions that continue to block the city's streets. (Listen from 42m50)
