- Description: Atmospheric carbon dioxide concentration during the past 417,000 years (kya = one thousand years ago; i.e., present is at zero, right-hand side). Carbon dioxide levels are expressed as parts per million (volume). The blue part of the curve comes from historical carbon dioxide records from ice cores drilled at the Vostok station in Antarctica. The red part of the curve, on the other hand, illustrates the CO2 increase to 380 ppm between 1800 and today due to anthropogenic emissions from fossil fuels. This increase happened (and happens) on a time scale below the resolution (and outside the time frame) of the Vostok data. The values are taken from other sources instead (see Image:CO2-Temp.png and Image:CO2-Mauna-Loa.png)
