“The revolution began in the mid-twenty-first century, after a few earlier false starts. It essentially happened when the Gulf Stream suddenly stopped. The methane released from melting tundra was too much. Only then did people walk out to the streets. They were completely non-violent, but it was positively everyone. Civilization basically shut down. Each person brought something to make noise with, and the sound was deafening. Many had gathered in the centers of power and raised the decibel level.”
