A downturn in global fossil fuel use has been prompted by curtailments of travel and social gatherings in response to the spread of the coronavirus. Could this downturn be reflected in atmospheric carbon dioxide readings that comprise the record known as the Keeling Curve, which is managed by scientists at Scripps Institution of Oceanography at UC San Diego? Scripps Oceanography … Read More
In honor of the 60th anniversary of the Keeling Curve, Ralph Keeling of the Scripps CO2 Program shows how scientists make carbon dioxide measurements and gives a guided tour of the original instruments his father, Charles David Keeling, developed to start the famous record known as the Keeling Curve. In 2018, carbon dioxide levels are expected to exceed 410 parts … Read More
Suggests that plants have achieved an optimum response to rising CO2 levels in the atmosphere
We are now approaching the annual low point in the Mauna Loa CO2 curve, which typically happens around the last week of September but varies slightly from year to year.
A hurricane bearing down on Hawaii prompted operators to shut down CO2 monitoring equipment at Mauna Loa Observatory on the Big Island.
A failed disk that had prevented the reporting of daily readings was replaced on June 14 and the system is now running normally.
