Tree restoration is seen as a nature-based solution to climate change, because trees remove carbon from the atmosphere. However, tree cover can influence surface temperatures in other ways, for example by changing albedo and enhancing evapotranspiration. These impacts may, in turn, be affected by increasing atmospheric carbon dioxide concentrations. Here, the authors present simulations with a coupled atmosphere-land-slab-ocean model to investigate how doubled atmospheric carbon dioxide levels affect warming in a high-end scenario where afforestation covers a land area 35% larger than the USA.
