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 ...
Oct 29, 2021 · Keeling instead used direct sampling with what is now called Keeling flasks. Surprisingly, they are still in use today: “Hold your breath and walk into the wind, then open the valve,” says Tim Lueker, a researcher in the CO2 Research Group at Scripps Institution of Oceanography, UC San Diego.
Starting in 1958, Charles Keeling used the scientific method to take meticulous measurements of atmospheric carbon dioxide (CO 2) at Mauna Loa Observatory in Waimea, Hawaii. This graph, known as the Keeling Curve, shows how atmospheric CO 2 has continued rising since then. The scientific method is the gold standard for exploring our natural world.
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.”.
Sep 22, 2023 · Dr. Charles David Keeling’s groundbreaking work in measuring atmospheric CO 2 levels and the creation of the Keeling Curve have been instrumental in advancing our understanding of human-caused climate change. His dedication to scientific inquiry and meticulous measurements laid the foundation for climate science as we know it today.
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 ...

Keeling presented his findings to Harry Wexler (1911–1962), director . of the Weather Bureau’s Division of Meteorological Research. Wexler was impressed by Keeling’s methods and offered him the job of leading the Weather Bureau’s proposed CO. 2. program. Shortly after, Keeling received an offer from Roger Revelle (1909–1991), director ...
