Global Warming - Outline
Thesis Statement: The emergence and persistence of global warming has largely been attributed
to various human activities since the days of industrial revolution, and the continuous rise in
global temperatures have continuously affected the flow or energy and materials in all
ecosystems, affecting all abiotic and biotic factors.

Overview
• Global warming is defined as the unusual and rapid rise of the
temperature levels on the earth’s surface.

• It’s emergence and persistence in the modern environment has been

attributed to the rising levels of greenhouse gasses into the atmosphere.

• Over the last centuries, the global temperatures have persistently risen
compared to any other period in human history.

• The main source of the greenhouse gasses, which are responsible for

global warming, is the continued use of fossil fuels by human beings.

• However, scientists have historically attributed global warming to natural

causes which are not influenced by human activities and are still existent,
but their effects are too negligible to account for the rapid rise in global
temperatures (Riebeek, 2010).

• Despite the previous rise in global temperatures, its estimated that the

overall global temperatures will rise to the range of 2°C and 6°C before
the close of the 21st century.

• The predicted rise is inevitable and will be experienced despite any
measures to reduce the levels of greenhouse gas emissions.

• The inevitability is justified by the already recorded climatic and

environmental alterations that have emanated from global warming.

• The earth’s environment will in turn respond to the rising temperatures by
such occurrences as changing rain patterns, amplification of soil erosion
along coastlines, molten ice caps as well as glaciers, extinction of various
species, and overall climate changes.

Effects of Human Activities on the Community and the
Biosphere and how this has Led to Global Warming

• Since the times of industrial revolution, human activities have been

characterized by the intensive establishment of industries and other
energy consuming items such as automobiles.

• Generally, human activities have played a leading role in the generation
of the rising levels of greenhouse gasses to the environment.

• Among the main unnatural sources of greenhouse gasses is the use of
fossil fuels in human activities.

• The greenhouse gasses emitted to the environment are responsible for
significant imbalances of the system.

Effects of Human Activities on the Community and the
Biosphere and how this has Led to Global Warming

• The combustion of such fossil fuels such as petroleum and coal result in

such emissions as Carbon IV Oxide, Methane, Nitrogen IV Oxide, and other
gases known for trapping heat on the earth’s surface.

• The use of fossil fuels in the industrial as well as domestic sectors result
in the emission of Carbon IV oxide.

• Agricultural activities are blamed for the release of methane to the

atmosphere, while the application of fertilizers as well as fossil fuel
combustion result in nitrous oxides.

• Halocarbons such as CFC-11 and 12 are also produced from human
activities.
