| Description | Forests mitigate climate change by absorbing $CO_{2}$. However, $N_{2}$O emissions in forests, which has 298 times larger global warming potential than $CO_{2}$, can diminish the climate mitigation role of forests. Thus, it is crucial to project not only $CO_{2}$ absorption but also $N_{2}$O emissions in forests to provide a scientific basis for the 1.5 °C Paris Agreement goal. This study used a biogeochemical model, called FBD-CAN, to project $CO_{2}$ absorption and $N_{2}$O emissions of South Korean forests from 2021 to 2080 under three climate scenarios, including the current climate, Representative Concentration Pathway (RCP) 4.5, and RCP 8.5. From 2021 to 2080, $CO_{2}$ absorption decreased from 5.0 to 1.4 Mg $CO_{2}$ $ha^{—1}$ $year^{—1}$ under the current climate with the aging of forests, while $N_{2}$O emissions increased from 0.25 to 0.33 Mg $CO_{2}$ eq. $ha^{—1}$ $year^{—1}$. Climate change accelerated the decreasing trend in $CO_{2}$ absorption and the increasing trend in $N_{2}$O emissions. The subalpine region had a faster decreasing trend in $CO_{2}$ absorption than the central and southern regions due to its older stand age. These findings provide scientific references for future greenhouse gas reduction plans and broaden our knowledge of the impacts of climate change on the climate mitigation role of forests. |
