M Jackson: How to grow a glacier

How to grow a glacier

In the 13th century, Genghis Khan embarked on a mission to take over Eurasia, swiftly conquering countries and drawing them into his empire. But, legend has it that there was one obstacle that even he couldn't overcome: a towering wall of ice, grown by locals across a mountain pass. M Jackson explores the ancient methods of growing glaciers and how they can be used to combat climate change. [Directed by Artrake Studio, narrated by Addison Anderson].

For centuries, communities in the Himalayas and Karakoram have grown their own glaciers, even 'marrying' male and female ice to create new reserves. These homemade glaciers serve as vital sources of water for drinking and irrigation, especially as climate change threatens traditional supplies. In Ladakh, farmers build horizontal and vertical ice structures, like 50-meter-high stupas, to store water through the dry season. Modern adaptations of these methods are spreading worldwide, helping people survive in some of Earth’s harshest environments.
