So, six ppm from May 2023 to May 2025 means 12 billion tons and change more CO2 in the air in two years.

When Charlie Keeling began direct observation of trace gases like CO2 in 1958, we were at 315 ppm, though large-scale increases in atmospheric CO2 through human activities really got going back in the 19th century.
