About David Keeling  

In 1955 Keeling was the first scientist to successfully measure carbon dioxide in Earth’s atmosphere. He continued to measure CO2 for the the next 50 years despite indifference and opposition from U.S. government agencies that failed to understand the importance of his work. Today in the National Academy of Science in Washington, the Keeling Curve stands beside Darwin’s finches and the double helix of DNA, as the scientific icon that most clearly illustrates the steady rise of CO2 in Earth’s atmosphere.

The Keeling Curve. It shows the relentless rise of CO2 in Earth’s atmosphere from 310 ppm in the 1950’s to more than 400 ppm in 2018.

350 ppm, the CO2 level in 1988, is considered the acceptable safe limit for CO2 in Earth’s atmosphere.

A history of CO2 between 1700. As you can see, CO2 in 1700, just before the industrial revolution, was at about 278 ppm. As factories and industries developed, by 1800, CO2 gradually rose to 282 ppm, 300 ppm by 1900 and 310 ppm by the 1950’s when Keeling began taking his measurements. The growth of CO2 after 1960 when has been extraordinary and unprecedented in climate history. In the 1980’s, thanks to research on CO2 inside ice cores, Keeling and other scientists began learning about ancient temperatures and CO2 levels hundreds of thousands of years ago. See below.


This is a record of CO 2 levels over the past 800,000 years. During this period, there have been at least nine warming periods Can you pick out the nine high pointed peaks of high CO2? Also the eight low in between valleys of low CO2?
 Lower CO2 levels have caused and accompanied ice ages while higher CO2 levels have caused warming periods such as the one we have been for the past 11,000 years.


These two graphs show CO2 levels in blue (top) and temperatures (bottom) in red in Antarctica over the past 400,000 years.
 Can you see the striking correlation between CO2 levels & temperatures?
