Sensitivity experiments
A positive climate feedback is associated with the carbon cycle (Klepper and deHaan, 1995) due to a different response of ocean and land CO2 uptake when the climate warms A large uncertainty exists about the rate of this feedback (20 to 200 ppm among CGCM, Friedlingstein et al., 2006) Oceanic uptake...
