Mauna Loa CO2 record posts smallest yearly gain in its history - maybe
"The year end CO2 data for the Mauna Loa Observatory is out, and it shows that the trend of Co2 increase has slowed. This year saw the lowest increase in the annual mean growth rate ever in the Mauna Loa Co2 Record: 0.24 parts per million.
Whether this is real, a data error, or something else remains to be seen. As we’ve learned previously, the Mauna Loa record is not infallible and can be adjusted post facto. To MLO’s credit, they have been responsive to queries from myself and others, and have pledged to make improvements to the process. "
