The COVID-19 pandemic caused carbon dioxide (CO2) emissions from fossil fuels to drop in 2020 by seven percent compared to 2019. This decrease in emissions slowed the increase in atmospheric CO2 compared to what would have occurred without the pandemic. It was too small and too brief, however, to stand out strongly in individual CO2 records, such as the Keeling … Read More
Researchers Richard Betts from the UK Met Office Hadley Centre and Ralph Keeling of Scripps Institution of Oceanography, UC San Diego issued the following statement today regarding new record levels of CO2 in the atmosphere in the context of the Covid-19 pandemic. The full text of the statement with graphics is available with graphics through this link and is included … Read More
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
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
