GLOBAL CLIMATE CHANGE AND ITS IMPACT
1
Introduction
The issue of global warming is one of the crucial issues around the world and this
issue affects the global climate irrespective of the developing and developed countries of
different parts of the earth. In this essay, the issue of climate changes due to the excessive
emissions of the greenhouse gases is discussed in the country of Papua New Guinea (PNG).
Furthermore, the issue of global warming in Papua New Guinea is mainly reported due to the
population growth of the country and it in various studies it is stated that excessive
population growth is associated with the high emission of greenhouse gases in Papua New
Guinea.
Section I.
Background
The term greenhouse gas indicates towards those gas that can absorb and emits
radiant energy in between the thermal infrared range and as result the thermal energy only
enters into the surface of the earth and will unable to goes back to the atmosphere. Therefore,
it can be stated that more emission of greenhouse gas in the environment creates a layer in the
atmosphere and thus the heat cannot pass through that layers and deflected back to the earth.
As a result the average temperature of the earth is enhancing day by day. According to the
study of Anderson, Hawkins and Jones (2016), it is stated that the greenhouse gases have a
power to absorb the heat energy and thereby release those absorbed energy in the earth’s
surface. The amount of greenhouse gases in the atmosphere is directly proportional to the
average temperature of the environment. As these gases has the ability to hold the
temperature, thus enhanced amount of greenhouse gas can contribute to the climate change
issue of different countries of the world. In case of PNG, the growth of population has
contributed most to the issue of greenhouse effect in the country as an enhanced number of

populations in the country causes combustion of natural fuels such as coal, petroleum and
thereby the amount of the greenhouse gases in the country has enhanced greatly. In this
regard, it can be stated that combustion of such natural fuels in the environment causes
emission of greenhouse gases such as carbon di oxide, chlorofluorocarbon, methane and
ozone (Brechin 2016). As per the report of Sathre (2014), it is stated that the combustion of
carbon fuels has greatly contributed to the accumulation of the greenhouse gases in the
environment and thereby the shielding effects of those gases come into play and as a result
the heat cannot return to the atmosphere completely. Therefore, this shielding effect of the
greenhouse gases gradually contributes to the overall enhancement of the earth’s temperature.
Section II.
Problems for the Developing World
From various studies, it is reported that most of the developed countries are dependent
on different types of industry for their economic development that is those countries focus
primarily on the development of the industries for their overall growth. Therefore, it can be
stated that in order to help the economy dependent on the industry, the combustion of natural
fuel such as coal, petroleum is mandatory. According to the most recent data, it can be stated
that China is responsible for producing maximum amount of greenhouse gases around the
world (Agarwal, Narain, and Sharma 2017).
In terms of economic impact of the climate change due to greenhouse gas in the world
is mainly associated with various negative impacts. According to the study of Wu et al.
(2016), it is stated that the effect of such global climate change mostly affect the developing
countries of the world as most of the developing countries are dependent on agriculture and
so any kind of alteration in the climate affects the overall rain fall, average temperature of
that country and thereby the agriculture of the country will be effected in a negative manner.
