Is Climate Change a Result of Human Activities?

This article discusses the impact of human activities on climate change and its causes and effects. It covers topics such as greenhouse gases, fossil fuels, and the effects on agriculture and the environment. The article concludes with a call to action for individuals to prioritize environmental sustainability.

INTRODUCTION
The changes in the climate are mostly depends up on the human activities but are also affected
by natural activities such as volcano eruption, respiration, etc. some of the human activities that
has a grate impact on the atmosphere are burning of oil, fossil fuels, industrial waste, etc. the
human activities greatly affect the natural environment which in returns create ecological
imbalance (Breure and et. al., 2018.). The major effect of environment is on the agriculture
sector of the economy. The agriculture producers as well as consumer completely depends up on
the growth of crops but the imbalance n the environment makes it difficult for the crops to grow.
It is important for the industries as well as humans to understand the importance of the balanced
environment. The ozone layer depletion will cause the less reflection of the sunlight in the outer
space which makes some regions of the planets warmer whereas greenhouse gases can create
more reflection of sunlight which can create a more reflection of the sunlight in the outer space
which creates some regions cooler.
MAIN BODY
One of the major cause of climate changes and global warming is emission of harmful gases that
are creating a greenhouse effect and are combined of methane and carbon dioxide. The main
source of emission is because of burning of fossil fuels in order to ave energy consumption. The
additional contribution is made by deforestation, agriculture and manufacturing. The waste that
is produces by humans are also one of the major source of pollution. Riser in the temperature
increase the water vapour which is itself is a greenhouse gas and and is accelerated by climate
feedback. According to US energy secretary, 100% of global warming is caused by human
beings and they are responsible for all the pollution (Cetin, M., 2020.). Scientists have various
measures that determine the various factors that affect the amount of energy reaches and remains
in the earth's atmosphere known as “radiative forcing”. The factors that are determined by the
scientists includes that greenhouse gasses that trap the outgoing heat, aerosols which are caused
by both volcanic eruption or human activities. These reflects sunlight and influence in the
process of cloud formation. It will also influence the changes in solar output as well as reflection
of earth's surface. The radiative forces generally have long term changes in the climate and the
earth's atmosphere. The cycle of the energy from the sun reaching to the earth is of
approximately 11 years. It has been observed that there is a slight increase in the solar activities

but it has a lesser effect on the earth's atmosphere or climate as compared to the effect of other
radiative forces.
The warming from greenhouse gases are being offset by fossil fuel products and sulphur
dioxide which in returns atmospheric aerosols. The formed atmospheric aerosols then reflects the
incoming solar radiations back into the solar system which causes formation of reflective high
clouds which cause low temperature on the earth. On the other hand Ozone is a green house gas
that is short lived which have the ability to trap the outgoing heat and increase the temperature of
the earth (Goudie, A.S., 2018.). The Ozone is not emitted due to natural circumstances but due to
the emission caused by the human beings in the form of the gases such as carbon monoxide,
methane, volatile organic compound and nitrogen oxide that breaks down in the atmosphere.
Some of the other short term reasons for changes in temperature is because of volcanic eruption
which can have a cooling effect on the atmosphere due to the high amount of sulphate aerosols
that has injected into the atmosphere. The sulphate aerosols injected in the atmosphere remains
for the few years and reflects back the incoming sunlight back into the outer space. Another
reason for climatic change is caused by deforestation in the snowy region which ultimately
increases the reflection of the sunlight into the outer space which is an another factor that can
have a cooling effect on the climate.
By the research conducted by the scientists it has been observed that around 110% of observed
global warming is caused by actions of humans. The burning of more fossil fuels is also one of
the m,major reason of climate changes and causing a major effect on the earth's atmosphere.
Some of the major causes of global warming are:
Carbon dioxide: It is very important component in the atmosphere as it can be caused by
both natural reasons as well as human activities(Kundzewicz, Z.W. ed., 2019.). The natural
reason are volcano eruption or respiration whereas human activities such as land use changes,
deforestation, burning of fossil fuels, etc.
Methane: This gas is more active than carbon dioxide but is less abundant in the
atmosphere. This can also be caused by both natural sources or by human activities. This
includes agriculture, rice cultivation, wastes in landfills, manure management associated with
livestocks that are domestic.
Nitrous oxide: it is one of the most powerful greenhouse gas which is produced sue to
soil cultivation practices, use of fertilizers, fossil fuel combustions and biomass burning.

Chlorofluorocarbons: This is also a greenhouse gas that is dependant entirely on the
industrial origin. This is the gas that is largely used in the number of industrial activities and are
produced by human activities only (Wan and et. al., 2020.). However, the production and release
of this gas is restricted by the international agreement and the industries can produce and restrict
that gas but only up to a certain limit. The ability to destruct the ozone layer are reduced and the
industries have certain limits.
It is observed that the changing climates and the changes in the greenhouse gases are completely
dependent up on human activities. The burning of fossil fuels and the emission of greenhouse
gasses are completely depends up on the activities of human. As a result so9me of the regions of
earth may become warmer which cause more evaporation and and precipitation. This will make
some regions of the earth dryer and some become more watery(Wen and et. al., 2018.). As a
result of stronger greenhouse effect the more warming can affect the glaciers and ice sheet
partially which will increase the sea level. It is also observed that increase in the higher carbon
dioxide level in the atmosphere can have both positive and negative impact on crop yields. Some
experiments states that carbon dioxide increases the growth of the plants and on the other hand as
a negative impact of carbon dioxide in the atmosphere is changing in temperature, water and
nutrients constraints or ozone( Xia and et. al., 2018.). One of the major disadvantage of climate
extremes is that the livelihood of the agriculture producers and consumers largely depends up on
the climate changes. The cause are drought, floods, extreme temperature can also leads to loss of
crops. The climatic changes are also likely to increase weed and pests in the environment which
is not at all good for crops as well as for agriculture.

CONCLUSION
From the above report it is concluded that the interference of humans in the environmental
factors can have a severe impact on the climate as well as on the atmosphere. It is important from
human to understand that ecological and environmental balance is important in order to have a
suitable environment. People are getting concerned about the factors and are preferring
environmental as well as sustainable products but they are only few individuals. Until and unless
every human being is concerned about the environmental damage it is difficult to bring changes.
