Is Global Warming a Natural or Man-Made Occurrence?

Global Warming is the increase of the worlds temperature. It was specifically stated in

ENCARTA Dictionary (2009) that it is partly caused by Greenhouse Effect. Greenhouse is a result of the

atmospheric pollution of gases. What I would like to reiterate however is the word partly. This

implies that there are other causes of what man consider as a curse of his generation. Man therefore is

to be partly blamed for global warming.

To fully understand global warming, one has to look to all its causes.

Microsoft Encarta (2008) has pointed out that the Earth has warmed and cooled many

times since its formation about 4.6 billion years ago. Several of the causes listed includes; a)

massive volcanic eruptions, which increased carbon dioxide in the atmosphere; b) changes inthe intensity of energy emitted by the Sun; and C) variations in Earths position relative to the

Sun, both in its orbit and in the inclination of its spin axis.

Seemingly, the earth has experienced several repeated retreat of the polar ice caps

which resulted to a cool and warm environment. The last warm environment happened about

125,000 years ago (Microsoft Encarta, 2008). During this period, greenhouse gases such as

carbon dioxide and methane naturally increase in the atmosphere from increased plant andanimal life.

In an internet article retrieved February 25, 2010 simple entitled GLOBAL WARMING,

it also highlighted that apparently the earth goes through a cycle of climate change which lasts

for about 40,000 years.
