Global temperatures experienced a negative anomaly between 1950 and 1980 due to aerosol masking
the verdict
SUPPORTED
the evidence backs this
confidence 83/100
Global temperatures experienced a pronounced slowdown or negative anomaly between 1950 and 1980, which multiple lines of research attribute to aerosol masking and global dimming offsetting greenhouse gas warming.

Contribution of solar radiation to decadal temperature variability over land.
2013 · cited by 20
Paper [1] notes a substantial decrease in surface solar radiation from the 1940s to the 1970s that caused significant cooling, accounting in part for near-constant global temperatures during that period.
