The documentary works surprisingly well, combining older films alongside recent shots of Iceland’s stark landscapes, to demonstrate the significant and continuing impact of global warming. Instead of relying solely on numbers and alarming data, Icelandic writer Andri Snær Magnason shares memories of his grandparents who have passed away, using a timeline based on their lives—and his own—to reveal glaciers they enjoyed skiing on during the 1950s, now reduced to piles of rock and rubble. It’s possible that without seeing those old films or pictures, one wouldn't even realize a glacier had once been present there. This immediate visual comparison is what powerfully reinforces the point he’s making, showing it as it unfolds. He mentions how processes that took thousands of years to develop are now being reversed within just one human lifetime. It seems likely that Iceland may eventually have to change its name. The film runs a bit long, but the beautiful photography of volcanoes blends with this moving family story, offering a very personal perspective on climate change, letting us witness the destruction as it occurs and continues to unfold.
