Keeling, Charles

[person]

American marine geochemist born in Scranton, Pennsylvania (1928-2005). Keeling researched the greenhouse effect and subsequent changes in Earth's atmosphere. Keeling helped establish a station on Mauna Loa in 1958 where monthly atmospheric CO₂ measurements have been taken ever since. His dedication to producing a long-term record was critical to showing that atmospheric carbon dioxide levels have been increasing over time. His work resulted in a greater awareness of the human impact on global climate.
