Is "An ice age is imminent due to global cooling" true?
Newsweek's 1975 "Cooling World" piece helped turn a short stretch of colder weather into a full-blown ice-age scare, complete with charts that looked convincing at a glance. The evidence behind the chill was real, just short-lived: industrial haze and a cool decade, not a century-scale slide. Once scientists tracked the longer carbon trend instead of that temporary blip, the direction flipped hard toward warming, and it hasn't flipped back. NASA and the IPCC now treat that reversal as one of the clearest signals in climate science.
What you were taught
An ice age is imminent due to global cooling
What we know now
In the 1970s, some media outlets speculated that the Earth might be entering a new ice age due to short-term cooling trends and aerosol emissions. However, climate science has since evolved, and the overwhelming consensus now shows that human-induced global warming—primarily caused by greenhouse gas emissions—is the dominant trend. Evidence from NASA and the IPCC confirms that the current warming rate is unprecedented over millennia and directly linked to human activity.
Was "An ice age is imminent due to global cooling" taught in school?
Yes — and not as a joke question on a quiz. This science claim showed up in textbooks, worksheets, and classroom posters through the 1970s, which is why so many people still remember it as settled fact long after the science moved on.

When was this understanding updated?
The evidence had largely shifted by around 1988. Schools don't flip overnight, though — plenty of classrooms kept teaching the older version for years after researchers had already moved on.
