Global Cooling (not to be confused with Global Warming) is the largely accepted theory that the earth is gradually getting cooler due to human activities. Global has recently been cast down in the media spotlight, as Global Warning takes center stage. People believe Global Warning to be a much more pressing issue, because of the attention the government has given it.

Global Cooling was around more in the 1970s, until the conspiracy concocting scientists realized Cooling wasn't very scary. So they switch to warning, scarier and more threatening.
