Action Requires Awareness
Long-term observations of earth’s environment and climate
Long-term records have the power to transform how we view the world.
Each year, due to lack of appreciation and support, we miss opportunities to collect crucial data.
We need environmental datasets like the Keeling Curve to track changes across the atmosphere, oceans, and land.
Our mission is inspired by the Keeling Curve
Our Mission
To extend Charles D. Keeling’s scientific legacy by advancing, promoting, and protecting long-term environmental observations
Continuing the Legacy of Charles David Keeling
Hawai'i 1958
Charles David Keeling initiated the long-term measurements of CO₂ at the Mauna Loa atmospheric observatory.
Early 1960s
His record – known as the Keeling Curve – set off alarm bells that fossil fuel burning was having a negative impact on the environment.
Program in Danger
Funding cuts in the 1960s seriously threatened the program. Few agencies saw value in supporting the same measurements each year.
Record-Setting
Charles David Keeling's long-term, persistent, and precise data tracking sets the precedent for environmental scientists across the globe.
Present Day
In 2022, the Keeling Curve Foundation was founded by Charles’ son, Ralph Keeling, to support other scientists who are similarly committed to long-term observations.
