Global cooling

For other uses, see Global cooling (disambiguation).

Global cooling was a conjecture, especially during the 1970s, of imminent cooling of the Earth culminating in a period of extensive glaciation, due to the cooling effects of aerosols or orbital forcing. Some press reports in the 1970s speculated about continued cooling; these did not accurately reflect the scientific literature of the time, which was generally more concerned with warming from an enhanced greenhouse effect.

An overall warming trend from the late Industrial Revolution did slow and reverse slightly from the 1940s to the 1970s, but then continued sharply upward into the 2020s.
