The water is getting warmer, and the ice cap is melting. Thor, the walrus, is at risk of losing his homeland. Thor lives in the seasonally ice-covered waters of the Arctic Circle with his mother, his friends, and the elders. The ice is brittle and breaks easily. Thor hears the elders talk about climate change and wonders what it means. Being named after the god of thunder, Thor decides he is a brave walrus who will one day embark on an adventure to explore far-off lands to find out more. One night, the ice breaks, and Thor floats away, leaving his mother, his friends, the elders, and his homeland behind. Thor's adventure has begun. As he enters warmer waters, his floating iceberg gradually melts until it disappears. Thor is on his own and swims for hours, looking for food and a place to rest. He visits coastal villages and a herring festival where the air is thick with the smell of fish. Every time Thor stops to rest and regain his strength, a crowd gathers, and Thor wonders why. He feels lost and alone, listening to the crowds. People were excited to see him. Men in orange coats kept the crowds at bay, but Thor was never far from the water's edge and would grunt if people came too near. He kept hearing the words 'global warming,' 'climate,' and 'change.' If people didn't act, his homeland would be lost. Thor decided that his journey could make a difference. While he majestically and playfully showed himself off, he hoped that Thor the walrus would never be thaw-forgotten.
