Q&A: Beavers, solar panels in the Sahara and nuclear waste

The Climate Question panel answer your queries. Do beavers protect the planet? Should we put solar panels in deserts? And why does the world need to upgrade its electricity grids?

Host Graihagh Jackson puts your head-scratchers to Justin Rowlatt, BBC climate editor; Akshat Rathi, senior climate reporter for Bloomberg News and host of Bloomberg's Zero podcast; and Caroline Steel, presenter of BBC CrowdScience.
