Global Warming and its effects
We, human beings, are accidentally or deliberately destroying our Mother Nature. No
matter how we advocate our actions, the result we have caused are becoming seriously day by
day. One of those results is popularly called global warming which show that the Earth is
warming up. Global warming is an increase in the temperature on the surface of the Earth; this
term is mostly used to refer to the warming predicted to occur as a result of increased emissions
of greenhouse gases. The Intergovernmental Panel on Climate Change (IPCC) recently
concluded that increased concentrations of greenhouse gases are causing an increase in the
Earth's surface temperature.
In fact, there are still some people who are politics or oil company doubt on the real
causes of global warming. Perhaps, the reasons make them do that are benefits. It is clear that if
people stop using fossil fuels and change to alternative energy resources such as solar energy or
wind energy, the oil industry will be underinvestment. According to Husain, vice president of a
construction and trading firm in Saudi Arabia, if the investments in oil industry do not meet the
future demands, they may have to stop expanding some projects which may delay oil supplies to
the world. As a result, it may affect serious the world economy. Therefore, Oil Company and
politics would be the first ones who want to advocate that global warming has nothing to deal
with environment. However, the scientists have proven clearly that global warming is real, it is
caused by greenhouse gases, and we must work together to understand and to save this planet
before it is too late.
How Global Warming works?
Theoretically, according to Farley (2008), the greenhouse gases, which are carbon
dioxide, methane and CFCs, are will create an invisible blanket in the atmosphere. When the
sunlight hit towards the Earth, infrared radiation will be absorbed by the land and sea and will
also be reflected to the space. However, that invisible blanket will trap this re-radiation; as a
result, the Earth will be warmed one more time.
The industrial revolution and the increasing of human population have led to the
extremely large demand of fossil fuels such as oil, coal, natural gases to support the growth of
economy and personal demands. The use of these fossil fuels have resulted the carbon dioxide,
methane, and other gases (Johansen 2006).
In fact, the effects of greenhouse gases are extremely important because without them,
the average temperature of the Earth would be -18 degree Fahrenheit (Farley, 2008). However, a
good question is if global warming can be a problem or not. Most scientists have done many
researches to show that carbon dioxide is currently the strongest greenhouse gases and “if the
atmosphere’s carbon dioxide level doubles over preindustrial levels, which is likely (at present
rates of increase) during the twenty-first century, several climate models indicate that
