ABSTRACT Carbon uptake by forestation is one method proposed1 to reduce net carbon dioxide emissions to the atmosphere and so limit the radiative forcing of climate change2. But the overall


impact of forestation on climate will also depend on other effects associated with the creation of new forests. In particular, the albedo of a forested landscape is generally lower than that


of cultivated land, especially when snow is lying3,4,5,6,7,8,9, and decreasing albedo exerts a positive radiative forcing on climate. Here I simulate the radiative forcings associated with


changes in surface albedo as a result of forestation in temperate and boreal forest areas, and translate these forcings into equivalent changes in local carbon stock for comparison with


estimated carbon sequestration potentials10,11,12. I suggest that in many boreal forest areas, the positive forcing induced by decreases in albedo can offset the negative forcing that is


expected from carbon sequestration. Some high-latitude forestation activities may therefore increase climate change, rather than mitigating it as intended. Access through your institution
