Global temperatures have already increased by around 1.3C above pre-industrial levels, but this warming is not spread evenly across the planet. The Arctic, despite being one of the coldest regions on Earth, has become a hotspot for global warming.

Local temperatures there are rising as much as four-times faster than in other parts of the world. This rapid warming is unsettling the delicate environmental balance, causing significant ice loss – with implications for both the region and the wider world.

In a previous episode on the Arctic region, Graihagh Jackson explored the impact that climate change was having on the people – and ice sheet – of Greenland. In the second part of The Climate Question's focus on the High North, she explores the implications of an increasingly ice-free region on global politics, military relations, and trade.
