After the Arctic's warmest winter ever recorded, the residents of Svalbard are witnessing the effects. Professor Chris's students measure a glacier, Alex takes a tour to a Russian mining settlement, and Lara spends a day cleaning up after 200 dogs.

Visitors are a big deal in lonely Svalbard. See how the residents react when Christine's sister visits from England, Mary Ann's son travels 1700 kms to save her disastrous kitchen, and an international opera singer arrives from Copenhagen.
