Carbon uptake by forestation is one method proposed to reduce net carbon dioxide emissions to the atmosphere and so limit the radiative forcing of climate change. 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 lying, and decreasing albedo exerts a positive radiative forcing on climate. Here I… Expand
Implications of albedo changes following afforestation on the benefits of forests as carbon sinks
Abstract. Increased carbon storage with afforestation leads to a decrease in atmospheric carbon dioxide concentration and thus decreases radiative forcing and cools the Earth. However, afforestationExpand
Climate warming feedback from mountain birch forest expansion: reduced albedo dominates carbon uptake.
TLDR
An empirically based projection of mountain birch forest expansion in south-central Norway under climate change and absence of land use finds that the current forest line of the region is circa 100 m lower than its climatic potential due to land-use history. Expand
Title Radiative forcing of natural forest disturbances Permalink
Forest disturbances are major sources of carbon dioxide to the atmosphere, and therefore impact global climate. Biogeophysical attributes, such as surface albedo (reflectivity), further control theExpand

[1] We estimated the magnitude of the radiative forcing (RF) due to changes in albedo following the forestation of peatlands, and calculated the net RF by taking into account the changes in both theExpand

Contribution of Semi-Arid Forests to the Climate System
TLDR
It is reported that a shift in peak photosynthetic activities from summer to early spring would, indeed, cause carbon accumulation by the forests, but that a suppression of reflected longwave radiation effect would complement the better-known (shortwave) albedo effect, doubling the amount of potential warming.

Incorporating changes in albedo in estimating the climate mitigation benefits of land use change projects
Abstract. Some climate scientists are questioning whether the practice of converting of non-forest lands to forest land (afforestation or reforestation) is an effective climate change mitigationExpand
