The 2020 Global Carbon Budget was released by the Global Carbon Project team of scientists in December 2020. The annual budget is an assessment of the sources of carbon dioxide emissions from fossil fuels and deforestation, the growth of CO2 in the atmosphere, and the uptake from terrestrial and ocean processes. The newest edition, uses a wide range of global observational datasets from in-situ monitoring and remote sensing, combined with data from process-models, the Global Carbon Project provides a multi-decadal perspective on the carbon cycle up to the most recent full calendar year, 2019, also providing a forecast for the following year, 2020.

Summarizing the major findings from this budget, Dr. Ben Poulter from NASA Goddard, one of the members of the the team, stated, 'The economic effects of COVID19 caused fossil fuel emissions to decrease by 7% in 2020, but we continue to see atmospheric CO2 concentrations increase, by 2.5 ppm, or about 5.3 PgC. This means that the remaining carbon budget to avoid 1.5 or 2 degrees warming continues to shrink, and that we need to continue to monitor the land, ocean, and atmosphere to understand where fossil fuel CO2 ends up'.

The U.S. Carbon Cycle Science Program Office has been collaborating with the Global Carbon Project since 2007. The Global Carbon Project is a Global Research Project of Future Earth and a research partner of the World Climate Programme (WCRP). As part of its mandate to promote international cooperation around global change research, the USGCRP coordinates activities with Future Earth and WCRP and contributes to their core funding.

2020 Global Carbon Budget figuresKey Highlights of the 2020 budget:      

-          For 2019, total emissions were 11.5 GtC (Gt=billion tonnes), the growth of CO2 in the atmosphere was 5.4 GtC (or 2.54 ppm), uptake by the oceans was 2.6 GtC and by the land 3.1 GtC.

-          Fossil fuel emissions in 2019 grew by 0.1% over 2018 emissions, distributed among coal (39%), oil (34%), natural gas (21%), cement (4%) and other sources (1.5%).

-          Atmospheric carbon dioxide concentrations in 2019 reached 409.9 ppm.

-          The 2019 land sink (3.1 GtC) was slightly lower than the decadal mean of 3.4 GtC.

-          The budget imbalance, an indicator of the budget uncertainty, grew to 0.3 GtC from the decadal mean of 0.1 GtC, meaning that unexplained sources of interannual variability in sources or sinks remain.

-          Because of COVID-19 related economic changes, the forecast for 2020 emissions expects approximately 7% decline in global fossil fuel emissions. But this depends on the recovery trajectory followed by industrialized nations.

 

'The Global Carbon Budget is produced by more than 80 researchers working from universities and research institutions in 15 countries working under the umbrella of the Global Carbon Project. This edition of the annual update includes contributions from multiple organizations and research groups around the world that generate original measurements and data used to complete the global carbon budget (NOAA 2020)', including many U.S. scientists and the work of U.S. Carbon Cycle Science Program or Carbon Cycle Interagency Working Group (CCIWG) member agencies and departments.

For instance, many NASA observations and models were used to formulate the 2020 budget. These include:

-          MODIS (Aqua/Terra)

-          GFED (fire emissions and deforestation fires)

-          LPJ (land surface carbon exchange)

-          Landsat (in LUHv2)

-          LUHv2 (land-cover change)

-          CASA (land surface carbon exchange)

-          ODIAC (surface fossil fuel emissions)

-          MERRA-2 (GMAO Reanalysis)

-          CGADIP (NASA contribution to aircraft CO2 concentrations)

-          OCO-2 XCO2

-         Different science teams such as those of the NASA Carbon Monitoring System (CMS), Interdisciplinary Sciences, OCO-2 Science, ABOVE, MODIS Science Teams. NASA Earth Science programs such as Land Cover Change, Carbon Cycle and Ecosystems Office, Airborne Sciences provide funding mechanisms for this work to be carried out.

'NOAA research efforts also contributed significantly to this global assessment. GOMO provided funding support for ocean carbon observation data collected by researchers at NOAA’s Atlantic Oceanographic and Meteorological Laboratory and Pacific Marine Environmental Laboratory. NOAA’s Global Monitoring Laboratory provided atmospheric carbon dioxide concentration data. Contributors to the 2020 paper include Simone Alin (NOAA-PMEL), David R. Munro (NOAA-GML/CIRES), Kevin O’Brien (NOAA-PMEL/CICOES) Denis Pierrot (NOAA-AOML), Adrienne Sutton (NOAA-PMEL), Pieter Tans (NOAA-GML), Rik Wanninkhof (NOAA-AOML), and Nick Bates (BIOS). NOAA’s Global Greenhouse Gas Reference Network, part of the Global Monitoring Lab provides atmospheric data for the Global Carbon Budget. The 2020 data show that the average rate of increase of CO2 in the atmosphere has been higher in the last decade (2010-2019) than at any other time in recorded history....NOAA’s Global Ocean Monitoring and Observing Program (GOMO) provides funding support for ocean carbon observation data that is used to determine the ocean sink, or amount of carbon absorbed by the ocean. A global collaboration called SOCAT (Surface Ocean CO2 Atlas) collects all surface water CO2 levels annually and is the cornerstone to quantify ocean CO2 uptake that is critical to the Global Carbon Budget. GOMO funded investigators provide over half the data for the SOCAT database, which is comprised of over 27 million observations spanning over six decades. In response to the atmospheric CO2 increase, the uptake by the ocean has increased as well; ocean CO2 uptake is influenced by oceanic processes and varies seasonally and decadally. The uptake has led to increasing levels of surface ocean acidification. The release of this year’s Global Carbon Budget comes ahead of the fifth anniversary of the adoption of the UN Paris Climate Agreement, which aims to reduce the emission of greenhouse gases to limit global warming. Cuts of around 0.3 to 0.6 Gt C (or 1 to 2 Gt of CO2) are needed each year on average between 2020 and 2030 to limit climate change in line with its goals. The magnitude of emission reductions, its verification, and impact on climate change depends, to a significant extent, on the ocean and land continuing to sequester CO2.  This requires a robust atmospheric, ocean and terrestrial CO2 observing system (NOAA, 2020).'
