Imagine our world in the not-too-distant future? In parts of the northern hemisphere, the temperature plummets to -90 F. At 130 below, public transportation fails. Those caught outside freeze to death.
Buildings collapse under the weight of snow and ice. The power goes out, society collapses, and anarchy takes its place. Could this be a vision of our future? In this documentary, Naked Science examines what may cause temperatures to plummet and how this could spell disaster for our planet.
