Charles David Keeling (April 20, 1928 – June 20, 2005)
Early life and early career
Keeling was born in
At Caltech he developed the first instrument able to measure carbon dioxide in atmospheric samples with consistently reliable accuracy.[5] Keeling camped at Big Sur where he used his new device to measure the level of carbon dioxide and found that it had risen since the 19th century.
Work with Scripps Institution of Oceanography, 1958–2005
Keeling worked at the Scripps Institution for 43 years during which time he published many influential papers.
Keeling started collecting carbon dioxide samples at the base in 1958.[3] By 1960, he had established that there are strong seasonal variations in carbon dioxide levels with peak levels reached in the late northern hemisphere winter. A reduction in carbon dioxide followed during spring and early summer each year as plant growth increased in the land-rich northern hemisphere. In 1961, Keeling produced data showing that carbon dioxide levels were rising steadily in what later became known as the "Keeling Curve".
In the early 1960s, the National Science Foundation stopped supporting his research, calling the outcome "routine". Despite this lack of interest, the Foundation used Keeling's research in its warning in 1963 of rapidly increasing amounts of heat-trapping gases. A 1965 report from President Johnson's Science Advisory Committee similarly warned of the dangers of extra heat-trapping gases, which cause the temperature of the Earth to rise.
The data collection started by Keeling and continued at Mauna Loa is the longest continuous record of atmospheric carbon dioxide in the world and is considered a reliable indicator of the global trend in the mid-level troposphere. Keeling's research showed that the atmospheric concentration of carbon dioxide grew from 315 parts per million (ppm) in 1958 to 380 (ppm) in 2005, with increases correlated to fossil fuel emissions. There has also been an increase in seasonal variation in samples from the late 20th century and early 21st century.
Personal life
Keeling was an enthusiastic outdoorsman who made many hiking and camping trips to the Western mountains, particularly the
Keeling married Louise Barthold in 1954. They had five children, one of whom (
Keeling died in 2005, aged 77, of a
Legacy
- At a White House ceremony held in July 1997, Keeling was presented with a "special achievement award" from Vice President Al Gore. Keeling was honored "for 40 years of outstanding scientific research associated with monitoring of atmospheric carbon dioxide in connection with Mauna Loa Observatory".
- The Keeling Curve is "engraved in bronze on a building at Mauna Loa and carved into a wall at the National Academy of Sciences in Washington." It was also a chart on the wall in a classroom at Harvard University where Revelle had moved to teach in the 1960s and where among others, student Al Gore would see and "marvel" at it. In 2006, Gore featured the graph in the book and movie An Inconvenient Truth.[5]
