In Pictures: The Arctic struggle

At only 1,000km away from the North Pole, the Norwegian town of Longyearbyen stands at the frontier of climate change. Here, homes constructed on a thawing permafrost balance precariously on unstable foundations, residents are plagued by frequent landslides, and rain - instead of snow - falls in winter. In February last year, Vanessa Liu and Mark Cheong visited the northernmost town in the world to explore how climate change is affecting everyday life in the Arctic.
