QuoteWith observations from satellites, however, it is now possible to directly measure the average global level of atmospheric CO2. According to CAMS, it rose by 2.9 ppm in 2024. That isn't a record, but it is one of the biggest increases since satellite observations began.So even though the Mauna Loa measurement is clickbait cherry picked OMG, 2.9 ppm a year keeps the upward trend going right along.
I also wonder at the statement "since observations began." The CAMS site isn't easily giving up data. Maybe those numbers reside elswhere in an easier to access form?
