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 …
Monthly average surpassed 414 parts per million at Mauna Loa Observatory
Suggests that plants have achieved an optimum response to rising CO2 levels in the atmosphere
A hurricane bearing down on Hawaii prompted operators to shut down CO2 monitoring equipment at Mauna Loa Observatory on the Big Island.
Note: Readers have asked why there has been no stabilization in the measured levels of the greenhouse gas carbon dioxide in the atmosphere when reported emissions of CO2 have fallen. Scripps CO2 Group Director Ralph Keeling gave this response:
Scripps Oceanography lab monitoring atmospheric CO2 named National Historic Chemical Landmark
In response to a reader question on news of a slowdown in the rate of CO2 emissions rise, Scripps Institution of Oceanography, UC San Diego, geochemist Ralph Keeling said
Global mean temperatures have been flat for 15 years despite the increase in heat-trapping greenhouse gases, but a new Scripps study shows cooling in the equatorial Pacific Ocean explains the discrepancy
