global cooling
Earth temperature decline
Global cooling is the hypothesis that Earth's average temperature is declining, or a period when such decline occurs.
The term gained attention in the 1970s when some scientists predicted cooling trends, though this was never the scientific consensus.
Today it appears most often in arguments disputing global warming: What about the global cooling scare in the seventies?
