Farman, Gardiner and Shanklin: severe springtime Antarctic ozone loss

What changed

A severe seasonal Antarctic ozone-loss phenomenon became an evidenced scientific problem.

Scientific scope

The 1985 observation and proposed interpretation; full chlorine-catalysis mechanism, satellite follow-up and policy response are separate.

Evidence

The linked sources identify this contribution and its scope. WRS has not independently reconstructed the scientific claims. The paper’s observation and proposed chemical interpretation do not alone establish the complete chlorine-catalysis mechanism or later policy effects.
