Charles David Keeling (April 20, 1928 – June 20, 2005) [ 1 ][ 2 ] was an American scientist whose recording of carbon dioxide at the Mauna Loa Observatory [ 3 ] confirmed Svante Arrhenius 's proposition (1896) of the possibility of anthropogenic contribution to the greenhouse effect and global warming, by documenting the steadily rising ...
Apr 20, 2021 · When Keeling died in 2005, global CO 2 levels had risen to 380 ppm. This year, on April 3, 2021, we surpassed 420 ppm for the first time in recorded history. These measurements were both taken at the Mauna Loa Observatory, Keeling’s legacy. Yet, sixty-three years after its establishment, human-induced climate change is still a topic of ...
The first to make long-term measurements of CO₂. Charles David Keeling was the first scientist who committed his entire career to the long-term observation of climate change through the Keeling Curve, which has measured the earth’s CO₂ concentration since 1958. Because of the curve’s precision and simplicity, it sets a precedent for ...
Jun 11, 2010 · The influence of Charles David Keeling (1928−2005) was described in 2005 with little exaggeration by his colleague C. F. Kennel at the Scripps Institution of Oceanography: “Keeling’s measurements of the global accumulation of carbon dioxide in the atmosphere set the stage for today’s profound concerns about climate change.

Sep 22, 2023 · Introduction to Dr. Charles David Keeling Dr. Charles David Keeling, an American scientist born in 1928, made significant contributions to our understanding of climate change. He is best known for his pioneering work in measuring atmospheric carbon dioxide (CO 2) levels, which laid the foundation for our understanding of human-caused climate ...
Charles David Keeling was affiliated with Scripps Institution of Oceanography, University of California, San Diego, from 1956 until his death in 2005. His major areas of interest included the geochemistry of carbon and oxygen and other aspects of atmospheric chemistry, with an emphasis on the carbon cycle in nature and the abundance and air sea ...

Apr 30, 2015 · The atmospheric fraction appeared to be approximately 55%, meaning that roughly half of all CO 2 released by coal, oil and natural gas was remaining in the atmosphere, thus causing the Keeling Curve’s annual rise. This figure, reported by Keeling and colleagues at Scripps in 1973, is known as the “airborne fraction.”.
