Data and code for: Nature-based climate solutions can help mitigate the radiative forcing that follows deforestation

Widespread expansion of agriculture and forestry has altered the surface of the Earth, the composition of the atmosphere, and as a result, the climate. Here we quantify the radiative forcing caused by the deforestation of an ecoregion of the U.S. Upper Midwest and the adoption of eight nature-based climate solutions. We combined forest inventory data with over three decades of remote sensing and in situ data from a replicated land use change experiment. Deforestation of the region caused net global warming (1626 ± 44 µW m-2), mainly from the 76 % reduction of ecosystem carbon stocks, but also from the 84 % reduction of the soil methane sink and the 115 % increase in soil nitrous oxide emissions. The associated albedo increase offset 24 % of the greenhouse gas induced warming. For the adoption of nature-based climate solutions, we found that conservation agriculture provided a modest -39 to -76 ± 31 µW m-2 of climate mitigation, short/medium length forestry rotations provided more at -296 to -881 ± 44 µW m-2, and natural forest regeneration provided the most at -1555 ± 44 µW m-2. As the impacts of climate change on nature and society intensify, consideration should be given to the climate mitigation, habitat, and ecosystem services that nature-based climate solutions can provide.
