Keeling (CO2) Curve 50th Anniversary

Keeling (CO2) Curve 50th Anniversary

The 50th anniversary of the work started by Charles Keeling at Mauna Loa, Hawaii in the 1950s is honored in this cover story from the December 6th, 2007 issue of Nature Journal: Earth monitoring: Cinderella science.

According to Nature Journal, “The Mauna Loa measurements constitute the longest continuous record of atmospheric CO2 in the world. The steady rise in CO2 that they record now forms the accepted backdrop to today’s climate science and economic and political decision making. As well as being an important resource in itself, the Mauna Loa record highlights the vital importance of Earth monitoring programmes.”

NOAA In Situ Carbon Dioxide (CO2) Measurements
According to the National Oceanic and Atmospheric Administration (NOAA), “Mauna Loa observatory has grown to become the premier long-term atmospheric monitoring facility on Earth and is the site where the ever-increasing concentrations of global atmospheric carbon dioxide were discovered.” The observatory is part of the NOAA – Earth System Research Laboratory (ESRL) – Global Monitoring Division (GMD). LI-COR’s LI-7000 CO2/H2O Gas Analyzer plays a role in ongoing research at the Mauna Loa observatory.

The Keeling Curve Turns 50
Scripps Institution of Oceanography created this special 50th anniversary Web site devoted to honoring Charles Keeling’s work. Scripps provides articles, a 50th anniversary video, and research papers that pertain to the significance of the Keeling Curve.

50th Anniversary of the Global CO2 Record Celebration and Symposium

This November 2007 conference included a symposium of presentations and panel discussions that addressed topics relevant to the carbon dioxide record. Several discussions were focused on managing carbon today and in the future, with visions of the kind of research needed to support these efforts.
