The definition of a greenhouse gas is at the same time very simple and very complicated for the ordinary man (or woman !) : such a gaz is “just” a gas mixed in the atmosphere that absorbs the infrared radiation emitted by the earth’s surface. We are not accustomed to these gases ...
In this 2-yr field study, three different severities of drying were compared to a continuously flooded condition to quantify effects on rice yields, greenhouse gas emissions, GWP and yield-scaled GWP (GWPY). The AWD treatments in order of increasing drying severity were: Safe-AWD (AWDS) where...
There are two ways to deal with climate change: mitigation of Greenhouse gases (GHG) emissions and adaptation to new climatic conditions. To achieve mitigation goals, accurate quantification of GHG is required. For this reason, GHG emission inventories are prepared. In order to calculate all GHG ...
Each GHG possesses a unique heat trapping power and lifetime in the atmosphere. Having taken CO2as thereference pointof GHGs,GWPis a tool to compare the potential of various gases in terms of their heat trapping capacity in the atmosphere with that of CO2over a specified period. The Kyoto ...
In the Global Warming Potential (GWP) framework, for any gas, CO2-eq is calculated as the mass of CO2, which would warm the earth as much as the mass of that gas: it provides a common scale for measuring the climate effects and global warming impacts of different gases. In practice, ...
In this paper, in order to contribute to the definition of mitigation measures by the local administration, the balance of emissions and removal of greenhouse gases, assessed following the IPCC guidelines, for an Italian city (Reggio Calabria) on the date of 1 January 2020 is presented. Several...
industrial processes and are also considered greenhouse gases. These include hydrofluorocarbons, perfluorocarbons and sulfur hexafluoride. Although they are present in the atmosphere in very small concentrations, they trap heat very effectively, making them high "global warming potential" (GWP) gases. ...
methane (CH4), nitrous oxide (N2O), and ozone (O3).2 Because different greenhouse gases absorb and re-radiate different wavelengths of infrared light, and because they remain in the atmosphere at different levels and lengths of time, each type of greenhouse gas traps a different amount of ...
The output of greenhouse gases (GHGs) has also increased in the same way. Carbon dioxide (CO2), Nitrous Oxide (N2O), and Methane (CH4) is the most significant greenhouse gases (GHGS) that are producing a variety of disastrous consequences due to climate change. Despite the fact that CH4 ...
in the soil, which in turn increases the rate of decomposition of organic material, resulting in high CO2emissions from drained peatlands5,6,7. In addition to CO2,peatlands also emit the powerful greenhouse gases (GHG) CH4and N2O8,9,10. The emissions of these gases are known to be ...
