A new study indicates that expanding forests may have a limited impact on climate change mitigation due to offsetting factors.

A new study reveals that expanding forests could limit their potential to tackle climate change due to complex side effects. Using models of Earth's atmosphere, land, and oceans, researchers found that while forestation increases carbon dioxide removal, changes to other greenhouse gases and the reflectivity of the land surface may partially offset these benefits. The study, led by the University of Sheffield and published in the journal Science, suggests that the positive impact of forestation on climate change mitigation may be smaller than previously thought.
