Claim: In the 1920s and 1930s, scientists or authorities claimed that global cooling would kill the world.
5%Reasoning:
- The 1920s and 1930s were actually a period of documented warming, not cooling. Scientific and historical records show a "pronounced warming trend" during this era, particularly in the Arctic12.
- Media coverage from the late 19th century through approximately the 1920s focused on potential ice ages, but by the late 1920s and 1930s, media outlets shifted to reporting on warming trends instead34.
- The well-documented "global cooling" scare involving scientists and media predictions of a coming ice age occurred primarily in the 1970s, not the 1920s-1930s56.
- In 1933, the New York Times published an article titled "America in Longest Warm Spell Since 1776; Temperature Line Records a 25-year Rise," which directly contradicts the claim of a 1920s-1930s cooling panic4.
- The "global cooling" narrative that is sometimes cited by climate skeptics today is most commonly associated with a small minority of scientific papers and widespread media coverage in the 1970s, not the earlier decades57.
Conclusion: The claim is historically inaccurate. The 1920s and 1930s were marked by warming observations and concerns, not global cooling fears. The documented global cooling scare occurred decades later.
