- • We present a carbon cycle with an uptake proportional to the CO2 concentration.
- • Temperature dependent natural emission and absorption rates are considered.
- • The average residence time of CO2 in the atmosphere is found to be 4 years.
- • Paleoclimatic CO2 variations and the actual CO2 growth rate are well reproduced.
- • Human emissions only contribute 15 % to the CO2 increase over the Industrial Era.
