How much CO2 was there before?
Measurements of CO2 levels in Ice cores collected in Antarctica and Greenland indicate that the preindustrial carbon dioxide level was 278 ppm. Between 1000 and 1800 A.D. that level varied by no more than 7 ppm.
What about human activities?
The CO2 levels have now reached 386 ppm, which means human activities have increased the concentration of atmospheric CO2 by 109 ppm or 39 percent.
Notes:
MMT: Million Metric Tons
GT: Gigatons (billion tons)
Sources: CASF/MSRB; CDIAC; Netherlands Environmental Assessment Agency; Earth Systems Research Laboratory; Mauna Loa CO2 monthly mean data.
The following data were used to calculate the total mass of atmospheric CO2 :
1. Mass of dry air: 5.1352 × 1018 kg
2. The mean molar mass of air: 28.9625 g/mol.
3. Molar mass of CO2: 44.0095 g/mol.
4. Mauna Loa CO2 monthly mean data: 385.60ppmv
[On various websites reporting the carbon dioxide emissions, the total amount produced by human activities since 1750 varies from about 1.3 – 1.8 trillion tons. On one website the amount is published once as 1.36 trillion tons and again as 1.71 trillion tons of CO2 on separate pages.]
