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 thatabsorbs the infrared radiation emitted by the earth’s surface. We are not accustomed to these gases bec...
“Even though these greenhouse gases hold the heat from the sun the greenhouse effect is what keeps the Earth’s temperature suitable for life. Without the greenhouse effect Earth would be frozen and no one would be able to live on it” (“Global Warming- Britannica”). Many people believe...
Greenhouse gas emissions refer to the release of gases into the atmosphere that contribute to the greenhouse effect and global warming. These gases, such as carbon dioxide and methane, absorb longer wavelength radiation and increase the atmospheric temperature. ...

1.2. Why focus on removing non-CO2 greenhouse gases? Though CO2 currently contributes the largest part (65%) to radiative forcing, with CH4 in second place at 17%, reduction of CH4 may have a disproportionately large effect in arresting future global warming. This is because of the role of...
However, the term net-zero needs some sort of definition, although this is currently missing from the UNFCCC text. One online source offers the following; Net phase out of GHG emissions means that anthropogenic emissions of greenhouse gases to the atmosphere decrease to a level equal to or smal...
The definition of "greenhouse effect"2. Read the passage again and answer the following questions.(1)What would happen if there was no "greenhouse effect"?(2)What kind of radiation can react with greenhouse gases?(3)How can we reduce the negative effect of the "greenhouse effect" on the ...
You will learn from this course about basic concepts, including the main greenhouse gases considered to be responsible for global warming, the classification of greenhouse gas emissions (scope 1, 2 and 3), the definition of the concept of carbon neutrality or the principles that an organization ...
The earth system, rather than ‘holding incoming energy back’, radiates whatever it needs to radiate to balance the incoming from the sun, from whatever level(s) convection brings the surface heat up to, from where the ‘radiatively active gases’ radiate it back out to space. (Without thei...
4a). Emitted gases accumulate in its chamber headspace. The change of mixing ratio can be analyzed with various gas sensors, e.g., gas chromatography (CO2, N2O, CH4), IR-spectrometry including NDIR and FID with and without pumps (CO2, CO, CH4), chemiluminescence (NOx), Cavity-Ring-Down...
