Reforestation efforts to restore stocks of depleted forests are important for addressing climate change and for sequestering and restoring carbon from the Earth's atmosphere. These types of solutions to reduce carbon emissions are critical after 2023 turned out to be the warmest year on record. However, some models were found to be inaccurate. New research from Michigan State University found that the carbon removal potential of some afforestation models was overstated—and not by a small factor—but by as much as threefold. The goal set by the 2015 Paris Agreement for countries to limit global warming to 1.5 degrees is now close to being met. (From Michigan State University, more at phys.org)
