Charles David Keeling

Charles David Keeling was an American scientist renowned for his groundbreaking work in climate research, particularly for establishing the Keeling Curve in 1958, which graphically represented the continuous rise of atmospheric carbon dioxide levels at the Mauna Loa Observatory in Hawaii. His meticulous measurements revealed the impact of human activity on greenhouse gas concentrations, fundamentally changing the understanding of climate science and highlighting the urgent need for action against climate change.
