The Concentration and Isotopic Abundances of Carbon Dioxide in the Atmosphere
Charles D. Keeling
Overview
Keeling reported the first precise, systematic measurements of atmospheric carbon dioxide, taken at Mauna Loa and the South Pole. The data revealed a regular seasonal cycle and the beginnings of the steady rise now known as the Keeling Curve.
Began the record that proved CO₂ is rising — the iconic 'Keeling Curve'.
Key findings
Methods
High-precision infrared gas analysis of air samples collected continuously at remote, well-mixed locations (Mauna Loa Observatory and Antarctica), with careful calibration to compare absolute concentrations.

Observational Evidence from Supernovae for an Accelerating Universe and a Cosmological Constant
By measuring distant exploding stars, this team found that the expansion of the universe is speeding up, not slowing down. The acceleration implies a mysterious 'dark energy' filling space — one of the great puzzles of modern physics.

Extraterrestrial Cause for the Cretaceous–Tertiary Extinction
The Alvarez team proposed that a giant asteroid impact caused the mass extinction that killed the dinosaurs. Their evidence was a worldwide layer of iridium — an element rare on Earth but common in asteroids — at the geological boundary.

A Measurement of Excess Antenna Temperature at 4080 Mc/s
Penzias and Wilson reported a faint, uniform microwave hiss coming from every direction in the sky that they could not eliminate. It was the cosmic microwave background — the leftover radiation from the hot early universe, and decisive evidence for the Big Bang.
