Assuming levels of atmospheric CO2 are 390 ppm [Average CO2] What is the pH of rainwater due to presence of carbon dioxide? Assumptions: Water temperature: 25 C and atmospheric pressure: 1 [atm] Now using MS-Excel calculate the pH of water for atmospheric CO2 of 500 [ppm] calculate the pH of water for atmospheric CO2 of 600 [ppm] calculate the pH of water atmospheric CO2 of 780 [ppm] plot a

In the big picture, 400 ppm is a low-to-middling concentration of CO2 for the planet Earth. Some 500 million years ago, when the number of living things in the oceans exploded and creatures first stepped on land, the ancient atmosphere happened to be rich with about 7,000 ppm of carbon dioxide. Earth was very different back then: the Sun was cooler, our planet was in a di Data are reported as a dry air mole fraction defined as the number of molecules of carbon dioxide divided by the number of all molecules in air, including CO 2 itself, after water vapor has been removed. The mole fraction is expressed as parts per million (ppm).

5290 Converting The Units: % = 390 Ppm CO2 (v/v), = I M- L 15L= Mi, = Ul 25 Ml = Cm3 Ppm, 390ppm CO2 today: This is more than what had happened naturally over a 20,000 year period (from the Last Glacial Maximum to 1850, from 185 ppm to 280 ppm). The time series below shows global distribution and variation of the concentration of mid-tropospheric carbon dioxide in parts per million (ppm). The atmospheric CO2 concentration currently is 390 parts per million by volume (ppmv), and continuing on a business-as-usual path of energy use based on fossil fuels will raise it to ˆ¼900 to 1100 ppmv by the end of this century (see the first figure) (1).
