evidence: Greenhouse effect occurs in the troposphere (the lower atmosphere layer), where life and weather occur. In the absence of greenhouse effect, the average temperature on Earth’s surface is estimated around -19°C, instead of the current average of 14°C (Le Treut et al., 2007). Greenhouse effect is produced by greenhouse gasses (GHG). GHG are those gaseous constituents of the atmosphere that absorb and emit radiation in the thermal infrared range (IPCC, 2014). Traces of GHG, both natural and anthropogenic, are present in the troposphere. The most abundant GHG in increasing order of importance are: water vapor, carbon dioxide (CO2), methane (CH4), nitrous oxides (NxO) and ozone (O3) (Kiehl and Trenberth, 1997). GHG percentages vary daily, seasonally, and annually. [...] Nitrous oxide (N2O) and nitric oxide (NO) are GHG. During the last century, their global emissions have rised, due mainly to human intervention (IPCC, 2014). The soil emits both N2O and NO. N2O is a strong GHG, whereas NO contributes indirectly to O3 synthesis. As GHG, N2O is potentially 300 times stronger than CO2. Once in the stratosphere, the former catalyzes the elimination of O3 (IPCC, 2014). In the atmosphere, N2O concentrations are climbing up due mainly to microbial activity in nitrogen (N)-rich soils related with agricultural and fertilization practices (Hall et al., 2008).
