Wildfires are an annual phenomenon across the arctic region, but this year they are far more intense than usual, we look at the drivers for these extreme fires and the consequences, in particular long term environmental change across the region. We visit Naples which is built on a super volcano. A new analysis is designed to help predict when it might erupt.
We hear from young scientists around the world on their hopes for the future and hear about the discovery of a new potentially earth like planet.Presenter: Roland Pease
