Our World travels to the fastest-warming place on earth: Svalbard. Deep inside the Arctic Circle, it is home to the world's northernmost settlement, Longyearbyen, which is estimated to be heating at six times the global average.

Add to this an energy crisis in Europe fuelled by the war in Ukraine, which many experts believe is now undermining the fight against climate change. Nick Beake finds out what is being done to try to save Svalbard as we know it.
