This is the idea behind recent proposals to plant more trees in Alaska, Greenland and Iceland. However, we recently published a paper in the journal Nature Geoscience arguing that tree planting is not a climate solution in…

Planting trees in high Arctic latitudes could accelerate rather than slow global warming, scientists say
Direct and indirect effects of afforestation on climate forcing at high latitudes and their relative magnitude over the life of the plantation. a, Plantation establishment disrupts previously intact soils and increases microbial carbon decomposition (1). This is exacerbated by enhanced soil insulation caused by increased snow entrapment and decreased snow cover (2). Growing trees exude carbon from their roots, accelerating…
