By now, you will know what the greenhouse effect is and how it contributes to causing the impacts of climate change. But do you know which greenhouse gases created by humans most contribute to global warming?

Not all have the same effect, nor do they come from the same sources, and in the same way each lasts for a different time in the atmosphere. To teach you a bit more about these gases, we’ve prepared a static infograph where you can check all this data about greenhouse gases simply, in a table.

We have excluded other variables such as the formation of water of anthropogenic origin and black carbon in snow for their lesser effect.

 

The effect of greenhouse gases

There are five gases of human origin that contribute most – together up to 95% of the total – to the increase in global warming. Here you will discover the source of their emission, the time they spend in the atmosphere and what percentage they contribute to the greenhouse effect.

Carbon dioxide is responsible for 53% of the level of global warming. It is the result of processes such as fuel use, deforestation and production of cement and other materials. Its permanence in the atmosphere varies, but it’s very high at all times: 80% lasts for 200 years and the other 20% can take up to 30,000 years to disappear.

Methane is the next of the greenhouse gases which has the biggest effect on global warming (15%). This is generated by activities such as livestock production, agriculture, sewage treatment, natural gas and oil distribution., coal mining, fuel use and is also given off from waste tips. It lasts an average of 12 years in the atmosphere.

Halogenated compounds such as CFCs, HCFCs, HFCs, PFCs, SF6 and NF3 are responsible for 11 % of global warming and generated as a result of the production of chemicals by diverse sectors such as refrigeration and air conditioning, electrical and electronic equipment, medicine, metallurgy, and so on. Depending on the type of compound, their duration in the atmosphere varies from a few months to tens of thousands of years.

Tropospheric ozone also has an 11% effect on global warming. This is a product of the reaction between the gases carbon monoxide (CO), nitrogen dioxide (NO₂) and VOCs (Volatile Organic Compounds), given off during the burning of fuels. These gases don’t last as long in the atmosphere as others, a matter of months at the most.

Finally, nitrous oxide also contributes around 11% to the global warming total. It comes mainly from the use of fertilizers, fuel use, chemical production and sewage treatment, and lasts longer in the atmosphere, up to 114 years. Greenhouse gases

How to avoid generating greenhouse effect gases

To avoid global warming, it is necessary to reduce greenhouse gas emissions. The best way is to commit to renewable energies, which generate clean electricity without harming the environment or polluting the air. Renewables also help preserve the oceans and forests, which are natural carbon sinks absorbing some of the carbon dioxide.

I have been published in peer review journals in thermodynamics, nucleation theory, tensile layers, capillary action etc and most recently on climate change (july 2019:EJERS). In 2017 and 2018 I published papers that rewrote kinetic theory so that it better matches known/accepted empirical findings for heat capacities of gases, than traditional accepted kinetic theory does (Journal Progress in physics). A consequence of my new kinetic theory is that intermolecular collisions are inelastic which differs from the traditional kinetic theory where all collisions are ill advised as being elastic. Inelastic collisions explains why temperature increases with pressure something that could not be explained in neither traditional thermodynamics nor kinetic theory. Also of importance is that I realized why work is lost by expanding system and this is basically a direct heating/potential energy increase of our atmosphere (In Journals: Physics Essays 2015 and Hadronic Journal 2019) A point of concern from all this becomes that so-called greenhouse gases may not be the main culprit in global warming (greenhouse gases are secondary). Rather our whole atmosphere (all polyatomic gases) will adsorb and re-radiate thermal energy, hence our whole atmosphere will act as a thermal blanket. This combined with lost work now representing the heating of our atmosphere means that it maybe man's activities rather than simply so-called greenhouse gases that is the route cause of global warming. The above has severe ramifications upon how we need to fight global warming. If you care to read my paper on global warming then please google EJERS and then go to archives and then click on July 2019. My paper is second from the bottom titled: "New Thermodynamics: Global warming and Man's Activities" I apologize if I come across as crass but the planet needs saving from humanity and this will require the likes of you to stand up and say so. Sorry but my voice does no get noticed no matter how loud I scream Sincerely Kent W . Mayhew
