On co2.earth, locate the annual atmospheric CO2 concentration data. From the table, identify the NOAA-ESRL Mauna Loa value for 2022, the SCRIPPS UCSD Mauna Loa value for 2021, and the NOAA-ESRL Global value for 2019. Also, state the latest update date for the NOAA-ESRL Mauna Loa data.
Navigate to 'https://www.co2.earth/' (or 'https://www.co2now.org/' which redirects). Click on 'CO2 Now' in the navigation menu. From the 'CO2 Now' dropdown, click on 'Annual CO2'. Locate the table displaying 'Atmospheric CO2 Levels Mauna Loa Observatory (MLO) & Global'. Identify the 'NOAA-ESRL MLO' annual mean concentration for the year 2022. Identify the 'SCRIPPS UCSD MLO (*)' annual mean concentration for the year 2021. Identify the 'NOAA-ESRL Global' annual mean concentration for the year 2019. Locate and state the 'latest update' date for the 'NOAA-ESRL MLO' data.
The NOAA-ESRL MLO annual mean concentration for 2022 is identified as 418.53 ppm. The SCRIPPS UCSD MLO annual mean concentration for 2021 is identified as 416.11 ppm. The NOAA-ESRL Global annual mean concentration for 2019 is identified as 410.07 ppm. The latest update date for NOAA-ESRL MLO data is stated as Feb. 5, 2024.
