The Arctic Circle is a remote, beautiful, and critical part of our planet. Covering one sixth of the Earth’s surface, and over twenty-four time zones, this region is home to more than four million people, and is critically important to keeping our world’s climate, weather, and oceans in balance. Like most everywhere in the world, the Arctic is being shaped by the forces of globalisation and is seen as a frontier of new economic opportunity, but perhaps more than anywhere on Earth, the Arctic is at the front-line of climate change. In this interview, I speak to H.E. Ólafur Ragnar Grímsson (Chairman of the Arctic Circle; President of Iceland, 1996-2016) on the crucial role of the Arctic Circle in the future of our planet, why we need to act now on climate change, and the huge economic, social, and cultural opportunities presented by the region if we engage in dialogue and cooperation.
