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
As of February 21, 2021, the CO2 data from the Scripps CO2 program are reported on a revised CO2 scale, which has the effect of lowering the recent Mauna Loa record by ∼0.08 ppm compared to the previous scale.
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
