So the percentage change in the concentration is (400 - 280) / 280 x 100% view the full answer Previous question Next question If the standard concentration of CO2 in the atmosphere is 280 ppmv (another subjective number because the real one was fixed by scientific associations and boards, and its value is 350 ppmv), the anomaly in the temperature of the lower troposphere (the layer of air just above the ground and in contact with the surface with not more than one meter thick) caused by CO2 (Partial Pressure from 381 ppmv [CcdL] = 0.00034 atm-m) under a total atmospheric pressure of 1 atm is: Thus if it takes as long to increase atmospheric CO 2 from 560 to 1120 parts per million by volume (ppmv) as it did to rise from 280 to 560 ppmv, for example, then the associated warming at the Earth's surface will be roughly linear. So the question then becomes, how fast do we expect atmospheric CO 2 to rise over the next century? All human civilization and agriculture developed when the CO2 level was about 280 ppmv and the (mean global annual surface) temperature was 286-287 K. Serious deviations from that either way have the potential to badly disrupt our agriculture and our civilization. Approximately a decade later, CO 2 reconstructions based on marine geochemical proxies indicated consistently low late Pleistocene (glacial-like) CO 2 values of ≈200–280 ppmv (11, 12). Consequently, the Miocene has been regarded as a geological period in which climate and the carbon cycle were essentially decoupled. than the around 280 ppmv which is measured in Antarctic ice cores. 280 +/- 10 ppmv is assumed to be the pre-industrial amount of CO2 in the atmosphere by the scientific community.
