Climate change

Sagan didn’t predict Venus’s heat — he measured it with radio waves, and proved the greenhouse effect wasn’t just earthly.

Keeling didn’t prove humans cause climate change — he proved we can measure the signal.

The first person to experimentally prove CO2 heats more than air under sunlight was a woman in 1856 — and her apparatus was simpler than your kitchen thermometer.

A gas detector built for Mars revealed Earth’s pollution — and mistook it for safety.

Tyndall didn’t discover climate change — he discovered why the atmosphere holds heat at all.

A postdoc and a chemist proved your fridge coolant was eating the sky — and changed how the world governs chemistry.
