Naturalist, Melanie Shipman presents Churchill, Manitoba through the seasons: Beluga whales, polar bears and the Northern Lights. This remote Canadian community is the center of unique nature experiences. In summer, hundreds of white whales follow the fish in shallow water as they sing and play around kayaks and divers. The polar bear males roam and snooze on the boulder beaches. With the cold, tourists flock to see polar bears from tundra buggies while spectacular northern lights dance overhead. Why do these experiences happen here and will they continue as the climate changes?
