Trends in Measured Atmospheric Carbon Dioxide (CO2) and Surface Ocean Partial Pressure of CO2.
This figure appears in chapter 16 of the Second State of the Carbon Cycle Report (SOCCR2): A Sustained Assessment Report report.
Black dots represent atmospheric CO2 measured in parts per million (ppm) at the Mauna Loa Observatory in Hawai‘i beginning in 1958. Surface ocean pCO2 data (grey dots) are measured in microatmospheres (μatm) from the Hawai‘i Ocean Time-series (HOT) station near Hawai‘i (see Figure 16.4, p. 672, for site location). Black and grey lines indicate linear trends after 1990. Atmospheric CO2 increased by 1.86 ppm per year; surface ocean pCO2 increased by 1.95 μatm per year.
