                                                       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 a 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. Most proponents of
this global warming ideology have definitive social and financial interests in these claims.

Global warming is real. It is not the result of a natural climatic adjustment. It is 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 is the straw that breaks the camel’s
back. It is the difference between a category three hurricane and a category four. Global warming is
an imbalance of nature.

The premise of global warming 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 hotter by the
minute. 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

Causes of Global Warming

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.


What is the most significant cause of global warming?

                                                       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.


The numbers can be confusing

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.


Continuing the chain…

                                                      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.
