Human beings are undoubtedly the cause of global warming
Among the many species of animals living on this earth, humans are undoubtedly the ones
that are cause of global warming. The activities of the human beings have resulted in the
phenomenon called global warming (Cook, et al 2016). Global warming is understood as
long-term increase in the average temperature of the climate system of the earth. Global
warming is an alarming situation that is having impact on the earth’s climate. Due to global
warming both flora and fauna gets affected. The impacts are drastic as it is having deeper
impact on the lives of the people. Global warming is resulting in average increase of the
earth’s temperature which is causing many types of weathers changes that has not been seen
before. This is either resulting in droughts or rainfalls which is taking lives of many people
all across the globe (Harvey, 2018). It is having impact on the production of the crops and
deaths of other kinds of flora and fauna species. In this essay there will be discussion about
the fact that how human beings are undoubtedly the cause of global warming.
Each year billions of tonnes of greenhouse gases are being released in the atmosphere. All the
reports by the international organisations have been suggesting that it is the human activities
that are causing this global warming. A conclusion was drawn in the Intergovernmental Panel
on Climate Change in its fifth Assessment Report that it is the human influences that is the
major cause of the global warming from the mid of the 20th century (Malm, 2016). The major
influences are in terms of greenhouse gases that are produced due to different types of
activities of the human. Some of the gases like nitrous oxide, methane, and carbon-dioxide.
Research shows that these greenhouse gases absorb the radiation and do not allow them to get
reflected back in the atmosphere. This absorption of the greenhouse gases increases the
overall temperature of the earth. The increase is not so fast that it can be visible so easily
rather the speed is very much slow but the effect is quite large. The research on the analysis
of the temperatures all across the globe suggests that in the past 100 years the average
temperature of the earth has increased by 1 degree centigrade (Chakrabarty, 2014). This
might not be looking such a big number but the impact can be clearly seen. Carbon in the
atmosphere has increased by 40% and methane by 150%. It is expected that the way in which
human activities are being carried out throughout the globe. This pace will be going to
enhance in the coming years.
Human beings are performing various activities such as generation of energy that is resulting
in the burning of the fossil fuels such as coal which is the major cause of the emission of

these greenhouse cases. The demands of the people increased rapidly and due to this
industrialisation got empowered. Due to this mass production started which resulted in higher
amount of emission of gases from the factories which paced up the process of globalisation
(Martens, 2014). In the mid-20th century the focuses of the companies were to enhance their
production so as to meet their global demands and they did not think anything about what
they are doing to the environment. These organisational practices were such that emission of
carbon become over increasing. It was the quest of the men for and more that has led the
world to reach to such levels where now it is a matter of higher concerns. This is also true in
the area of increasing energy need of the people where it is to be understood that with the
development of the people the use of electricity and other kinds of energy increased. For the
production of the electricity coals were burnt. This enhanced the amount of carbon that is
being released in the air. They kept on for long period of time. Another major industry that is
contributing in the increase in greenhouse effect is the cement manufacturing industry
(Fankhauser, 2013). The requirement of cement kept on increasing due to the numbers of
construction works being done in any nation. But in the manufacturing of the cement there is
production of the carbon dioxide in huge amount.
Transportation has also resulted in global warming. The numbers of transport on the road
kept on increasing decade after decade. Instead of using public transports people started using
their own vehicles for travelling on the daily basis (Leiserowitz, Maibach, Roser-Renouf,
Feinberg & Howe, 2013). Companies became global hence they needed transportation
mechanism to deliver the products of the home of the people. This added to the emission of
greenhouse gases. The movement of the people also resulted in increase of the numbers of
people on the road. The diesel vehicles which were the major source of transportation added
to this cause as they were the major emitters of the carbon pollutants.
Adding to this, human activities such as deforestation have also increased the pollution level.
This can be understood by the fact that trees consumes the carbon dioxide and since the
people started cutting trees for their own purposes the carbon content in the atmosphere
enhanced. In the name of the development and construction of basic infrastructures trees were
cut (Ma, et al 2010). This was done because of the fact that population of the whole world
kept on increasing and their needs are increasing day by day. According to the report by
World Bank just between the years 1990-2016 around 502,000 miles of forests have been cut
which is more than the area of South Africa (Mgbemene, 2011). Concrete jungles are
replacing the natural jungles. Every company, every nation wanted to become better than
