Northern Lights - Cornerstones: Alaska

Environmental journalist Jason Mark visits Alaska's remote northern rim, and on the shores of the Arctic Ocean at a barbecue with Inuits, he reflects on the impact of our lust for hydrocarbons. Whilst the ice melts beneath them, so the search goes on for oil in these northern parts. He tries to grasp what he sees as the bitter ironies of climate change, confirmed by his encounters with Inuit hunters and others who describe how much the weather is warming. Producer: Mark Smalley.
