  1. aridity index (AI), annual sums of precipitation (P, mm yr−1), annual means of global radiation (Rg in W m−2), annual minimum and annual maximum air temperature (Ta min-max in °C), annual means of changes (Δ = F−NF) in shortwave and longwave net radiation (ΔSWnet and ΔLWnet in W m−2), and changes in average annual sum (15 y) of net ecosystem productivity (NEP in gC m−2 yr−1). The last three columns present the years needed to balance between the warming effect due to SW and LW forcing by the cooling effect of carbon stock change (‘Break even time’ in years) according to Eq. 7.
