While some would call global warming a theory, others would call it a proven set of facts. Opinions differ vehemently. Let us consider global warming to be both a premise that the environment of the world as we know it is slowly, but very surely increasing in overall air and water temperature, and a promise that if whatever is causing this trend is not interrupted or challenged life on earth will dynamically be affected.

The prevailing counter opinion is that all that is presently perceived to be global warming is simply the result of a normal climactic swing in the direction of increased temperature. Many proponents of this global warming ideology have definitive social and financial interests in these claims.

Global warming and climate change are aspects of our environment that cannot be easily or quickly discounted. Many factions still strongly feel that the changes our Earth is seeing are the result of a natural climatic adjustment. Regardless of one’s perspective the effects of global warming are  a quantifiable set of environmental results that are in addition to any normal changes in climate. That is why the effects of global warming have catastrophic potential. Global warming may well be the straw that breaks the camel’s back. It could turn out to be the difference between a category three hurricane and a category four. Global warming as caused by greenhouse gas emissions can lead us to a definite imbalance of nature.

The premise of global warming as an issue of debate is that industrial growth coupled with non-structured methods we as humans use to sustain ourselves has created a situation where our planet is getting progressively hotter. We have seemingly negatively effected our environment by a cycle of harmful processes that now seem to be feeding upon themselves to exponentially increase the damage to our ecosystem.

Let us start our examination of Global warming with a study of its causes. Global warming is an overall state of existence that is the cumulative effect of hundreds of environmental factors. All of these join together in both a linear and random model to show global warming as a chain of events.

Most modern attention to the problem of global warming began with discussion of depletion of the Earth’s Ozone layer. Ozone (O3) is a molecular form of Oxygen. The Ozone layer is a relatively thin strata of these molecules set in the lower portion of the Earth’s stratosphere.
Depletion of the Earth’s Ozone layer has resulted in a large increase in Ultra Violet Radiation reaching the surface of the earth. Does this increase in UV rays equate to global warming? Not really. In fact most scientific opinion is that depletion of the Ozone layer results in cooling of both the stratosphere and troposphere. So why mention depletion of the Ozone layer as regards to global warming? Because it represents a needed balance between harmful radiation being allowed to reach the earth’s surface and our desire to stem the rapid increase in our air and water temperature. Remember, we are viewing global warming as a chain of events.

The primary cause of global warming is Carbon Dioxide emissions. CO2 is being pumped into our atmosphere at an insane pace; 8 billion tons of CO2 entered the air last year. Of course some of this is due to natural activity such as volcanic eruptions and people breathing. But the Earth is equipped to easily absorb those into the normal regenerative process. No, the beginning of global warming was caused by fossil fuels being burned and emitting plenty of CO2.

Currently in the world 40% of all CO2 emissions are caused by power plants. These are burning coal, natural gas and diesel fuel. Some power plants burn garbage. Some burn methane made from garbage. And discounting those super green electrical generating plants designed to issue negligible pollutants, all of our power plants let loose into the atmosphere CO2.

33% of all the CO2 sent forth is the product of cars and trucks. Internal combustion engines burning fossil fuels…gasoline and diesel spew forth a retching amount of CO2.

3.5% of all CO2 emissions are released from aircraft traveling our friendly skies. Unfortunately, jets and other aircraft deliver their payload of pollutants directly into the troposphere.

12% of all CO2 released into the atmosphere is related to buildings. This figure varies from one source to the next. Some place the percentage of emissions from buildings as high as 33%. What most of these figures do not address is the actual cause of the CO2 emissions. In newly constructed buildings, production of materials used in building and energy used during construction are sited as the cause of carbon dioxide emissions. In existing buildings the CO2 created by the energy upkeep of the building is the root of the emissions quotient. The general comparison is that buildings consume energy in the way that cars burn fuel. But the pollutants created in providing power for heating, air-conditioning, lights and other usage in buildings has already been factored. Honestly this double billing accounting is more the product of auto manufacturers looking to point the blame for global warming away from gas guzzling cars.

The point to remember is that 98% of all CO2 emissions are related to energy production and 80% of these emissions become greenhouse gases.

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.
