Will afforestation in temperate zones warm the Earth?

July 2011

For decades, forest researchers have known that planting trees on cropland or pastures (that is, afforestation) can lower the surface albedo and that landscapes with low albedo absorb more solar radiation than more reflective surfaces. Consequently, afforestation will typically darken the Earth’s surface (when compared to grasslands or deserts). In spite of this knowledge, many believe that afforestation will cool...
