Biogeochemical and biophysical effects in 2100 for four different forest management portfolios over Europe. The business as usual simulation which served as a control, was repeated three times with slightly different initial atmospheric conditions (see Methods “Equilibrium climate for the management portfolios”). The variability between these three repetitions was considered the minimal model noise of the climate model. The reported noise was taken to be the definition of one standard deviation. TOA denotes the radiative imbalance at the top of the atmosphere.
