Glaciers were a huge part of The Little Ice Age. At one point, thirty percent of the Earth was covered in ice. Numerous villages were threatened by impending glaciers that continued to creep closer and closer to their farms. In the French Alps, the glaciers became such a threat that people believed them to be possessed by demons. Because of this belief, priests were sent out to exorcise the demon from the glacier. When the exorcist attempts failed, it became obvious that the only way to avoid destruction was to retreat from the glacial front.
