Synopsis
Glaciers have shaped the Earth for millions of years. Ice sheets formed from interconnected rivers of ice during glaciation 34 million years ago. As temperatures warmed, glaciers began to advance and retreat, balancing winter accumulation with summer melt. Colossal icebergs occasionally calved into the sea, marking a cycle that has persisted through time. Directed by Susan Schuppli, "Moving Ice" addresses the effects of climate change, pollution, and capitalism on these vital ice formations. The film runs for 49 minutes.
