TL;DR: In this paper , the contribution of agriculture to radiative forcing of climate through emissions of greenhouse gases associated with land clearing and agricultural production is evaluated, focusing on three greenhouse gases, namely carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O), which is the balance between anthropogenic emissions, primarily caused by fossil fuel combustion and deforestation in the tropics, and uptake by terrestrial and oceanic sinks.
Abstract: This chapter evaluates the contribution of agriculture to radiative forcing of climate through emissions of greenhouse gases associated with land clearing and agricultural production. It focuses on three greenhouse gases, namely carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O). The increasing atmospheric accumulation of CO2 is the balance between anthropogenic emissions, primarily caused by fossil fuel combustion and deforestation in the tropics, and uptake by terrestrial and oceanic sinks. The current global average atmospheric concentration of CH4 is 1720 parts per billion by volume, more than double its pre-industrial value of 800 ppbv. The present global average atmospheric concentration of N2O is about 310 ppbv and it is increasing at a rate of 0.6-0.9 ppbv yr-1. While the contributions of industrial and agricultural activities to rising atmospheric levels of CO2, CH4, and N2O are documented, the quantitative impacts of other nitrogen gases, sulfur gases, and ozone are less certain.
