Not exact matches
Even though the relationship between co2 in air and dissolved in fluid is well known, and dozens of independent
calculations of
residence time center around a 5 to 6 year
residence time.
-- Mass balance
calculations, however, indicate that co2 concentrations should be twice as high as they are given the known emissions and the long
residence time, indicating a missing sink.
You are using the 5 years
residence time in all your
calculations which doesn't change the total amount of CO2 in the atmosphere with one gram per year, while you should have used the e-fold decay rate.
13 - C / 12 - C isotope mass balance
calculations show that IPCC's atmospheric
residence time of 50 - 200 years make the atmosphere too light (50 % of its current CO2 mass) to fit its measured 13 - C / 12 - C isotope ratio.
