In a world that’s constantly changing, consistent data tracking is crucial

The first to make long-term measurements of CO

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 scientists tracking long-term environmental data. 

Dr. Keeling’s son, Ralph, followed in his father’s footsteps. Through the Keeling Curve Foundation, he’s dedicated to preserving his father’s legacy and the importance of long-term observations of the environment through the Keeling Curve Foundation.

Precise measurements of the environment today are vital for the scientific efforts of tomorrow

After just a few years of research, Keeling Curve measurements in the 1960s rang alarm bells that fossil-fuel burning could have a negative impact on the global climate. Over the following decades, the Keeling Curve has served as a constant reminder to the world that cuts in emissions are needed in order to avert the dangerous effects of climate change.

Long-term measurements like the Keeling Curve document our failures and successes in averting the impacts of climate change

Long-term measurements have demonstrated successes in combating other environmental challenges, such as ozone depletion.

We look forward to when the Keeling Curve bends downward, transforming into a symbol of hope and progress in combating climate change.

Long-term observations of nature are vulnerable when underappreciated

Every year, long-term observations are at risk due to a loss of appreciation and interest. When we lose the data, we lose our ability to track our progress in combating climate change.
