Meet Charles David Keeling

---

Charles David Keeling was a notable American scientist who is renowned for his pioneering work in measuring atmospheric carbon dioxide levels, which led to the discovery of the Keeling Curve.

Keeling began measuring the levels of carbon dioxide in the atmosphere at the Mauna Loa Observatory in Hawaii. He discovered a consistent rise in carbon dioxide concentrations, which is now known as the Keeling Curve. This research provided crucial evidence of human-induced climate change.

Keeling conducted research on the ocean carbon cycle and discovered that the oceans absorb about a quarter of the carbon dioxide released into the atmosphere. This finding has significant implications for understanding the Earth's carbon cycle and how it affects climate change.

Keeling conducted research on paleoclimate, using ice core samples to reconstruct atmospheric carbon dioxide levels dating back to 1000 years. This research provided critical insights into the natural variability of atmospheric carbon dioxide and the human impact on climate change.
