The Mauna Loa carbon dioxide (CO2) record, also known as the “Keeling Curve,” is the world’s longest unbroken record of atmospheric carbon dioxide concentrations.
Continue reading What Does This Number Mean?
The Scripps Institution of Oceanography, UC San Diego O2 and CO2 programs have received funding from multiple sources that put these operations on a relatively secure footing for the next few years. Continue reading A Keeling Curve Funding Update – April 2015
The rate of growth in carbon dioxide concentrations in the atmosphere has accelerated since the beginnings of the Keeling Curve. Continue reading Is the Rate of CO2 Growth Slowing or Speeding Up?
Supports continued operation of the iconic measurement series Continue reading Wendy and Eric Schmidt Award $500,000 Grant to Keeling Curve
The story of the Keeling Curve is beautifully animated in this new video. The American Museum of Natural History will host a Google+ Hangout Sept. 9, 2014 on the topic of the Keeling Curve.
Scientists make CO2 measurements in remote locations to obtain air that is representative of a large volume of Earth’s atmosphere and relatively free from local influences that could skew readings. Continue reading How are CO2 Data Processed?
In a recent comment, a reader posted a graphic in which CO2 and sea-level rise appear to be correlated throughout the last 700,000 years. Continue reading How do CO2 levels relate to ice ages and sea-level?
