Desuden øges mængden med 1,2 – 1,4 ppmV årligt. Den gennemsnitlige koncentration nåede, i februar 2010, 390 ppmV (0,0390%), hvor det førindustrielle niveau lå på 278 ppmV, 315 ppmV i 1958, 330 ppmV i 1974 og 353 ppmV i 1990. (ppmv= parts per million by volume). The increase has accelerated the last 10 years, and the CO 2 level now has passed 390 ppmv. CO 2 concentration data from before 1958 are from ice core measurements taken in Antarctica and from 1958 onwards are from the Mauna Loa measurement site. Plants were grown under ambient CO 2 [390 parts per million by volume (ppmv)] or high CO 2 (780 ppmv) with or without abiotic stresses. We subjected plants to low pH or low N stress because both stresses are important in agricultural and ecological fields (Sawaki et al.

With additional CO 2 transferred to the oceans, pH would decline further; under worst-case scenarios, seawater pH would drop to between 7.8 and 7.9 by 2100. Recent proxy estimates that are better constrained indicate Pliocene atmospheric CO 2 levels of ∼390 ppmv (Pagani et al., 2010), which are comparable to today's levels (∼385 ppmv). However, if we place our estimates of Pliocene Arctic TSTs in a global context, most of the temperature response to climate forcing is due to increased temperatures at high latitudes. 2 of 390 ppmV. Calculated using the equilibrium coefficients of DICKSON and MILLERO 1987 and the CO 2Sys programme of LEWIS and WALLACE (1998).

ppm vs ppmv Both “ppm” and “ppmv” are abbreviations used in scientific calculations. They are dimensionless quantities. While using these terms one should be very specific and not be confused in using one in place of the other. ppm “ppm” stands for “parts per million”.
