How to grow a glacier

This will sure become a major preoccupation in further years... To read the full article click on the link.

"BACK in the 13th century, when news of Genghis Khan and his marauding Mongol hordes reached what is now northern Pakistan, the people there came up with an unlikely means of keeping them out. According to local legend, villagers blocked the mountain passes by simply growing glaciers across them."

"Whether or not these stories are true, the art of glacier growing - also known as glacial grafting - has been practised for centuries in the mountains of the Hindu Kush and Karakorum ranges. It was developed as a way to improve water supplies to villages in valleys where glacial meltwater tended to run out before the end of the growing season. Now, as these remote mountain communities come under pressure from population growth and climate change, researchers and development agencies are starting to take a serious look at whether growing new glaciers can really stop mountain streams from running dry."
