Which now mentioned allows us to follow our chain of event’s leading to global warming into the next most defined cause… Methane gas. Methane is released into the atmosphere from a dozen major sources. These include natural and man made emissions. Natural release of Methane is primarily from wetlands, (including agriculture) termites, the ocean, and hydrates. Non-organic releases are based from, landfills, livestock, waste treatment, and biomass burning. (More energy production). Almost all of this is offset by the Earth’s ability to absorb around 97% of the methane released into the air. But that remaining 3% is a serious problem. The molecular structure of Methane makes it 20 times as powerful a Greenhouse gas than CO2. So while there is a great deal less Methane to contend with than CO2, it is still the second largest link in the global warming events chain.


Not every Greenhouse gas is as obvious a villain as Methane. The next most potent problem is simple H2O water. How can water be a cause of global warming? Our atmosphere contains a set parameter of water as vapor. This vapor absorbs and radiates heat as does every molecule in the air. But when the lower atmosphere (troposphere) has excess water vapor that gaseous H2O is a potent greenhouse gas.

Another of the more commonplace greenhouse gases is Nitrous Oxide. NO2 can make your car go faster, or make you relax at the dentist. It has quite few beneficial uses. But as a greenhouse gas all it manages to accomplish is to be one more ingredient in out atmospheric soup. Cars using catalytic converters, fertilizer plants, manufacture of nylon, and nitric acid as well as being produced naturally in our oceans and rain forests, produce Nitrous Oxide.

All of the above plus quite a few other greenhouse gases comprise the foundation of global warming. As above and in all discussion of global warming they are cumulatively referred to as greenhouse gases. To understand the importance of these as the start and endpoint of global warming we must digress into a brief explanation of the greenhouse effect.
