Abstract

This work examines the impact of replacing forests with farmland and grazing areas on atmospheric composition. Using a global climate-chemistry model, we found that deforestation reduces biogenic volatile organic compounds (BVOCs), increases farming emissions, and shifts ozone chemistry. These changes result in a slight cooling effect on the climate. Restoring natural vegetation could reverse some of these effects.
