INTRODUCTION
Climate is referred to the weather condition of a region within a period of time. There
have been various changes in the climate of various regions within a few years. The activity
of climate change can be referred as changes in the various climatic terms such as pressure,
temperature, wind and precipitation of a location. The various human activities have led to
the changes in the climate. Perhaps, these changes have affected the humans and their
surroundings in a negative way. The study revolves around influence of human behavior
upon the changing climate. The report consists of a study on human activities and their
contribution upon the changing climate (Guo and et.al., 2020).
TASK
Climate change is a result of human activities
The change in climate has led to a lot of changes that have caused disruption in the
various life forms. The humans can be considered as a reason behind the changes caused in
the climate. The human activities have influenced the climatic conditions badly. The various
human activities include burning or exhaustion of the fossil fuels, deforestation and livestock
farming. The deforestation process has led to cutting down of trees which have reduced the
forest area on the globe. Also the greenhouse gases have had a huge contribution in the
greenhouse effect and global warming. The various causes behind the changes in the climate
have been discussed below.
 Greenhouse effect- There are various gases in the atmosphere that block the heat in
the earth’s atmosphere and prevents its escape. These gases tend to remain in the
atmosphere and hence have various physical and chemical effects in the atmosphere.
These effects have a huge effect and force the changes in the climate. There are
various gases that are a part of greenhouse gases such as water vapor, carbon dioxide,
Methane, Chlorofluorocarbons and nitrous oxide. Water vapor works as in a feedback
mechanism which allows occurrence of precipitation. Carbon dioxide is formed due to
various natural processes such as respiration and combustion. Methane is formed
during the decomposition process. Nitrous oxide is formed during the cultivation of
soil whereas chlorofluorocarbons are emitted in the atmosphere from the industries.
 Deforestation- The deforestation is also among the major causes behind climate
change. The deforestation has led to the cutting down of trees and hence resulting in
reducing the forest areas of the globe. Trees help in accumulating the rising Carbon
dioxide level but the lesser trees have reduced the oxygen level on the Earth which is
among the major cause of climate changes (Luan and et.al., 2021).
The various human activities that have led to above mentioned causes of climate change are-
 Burning of oil and coal lead to emission of carbon dioxide and nitrous oxide in the
atmosphere.

 Humans have cut down the forest areas in order to develop infrastructure of the areas
which have led to deforestation.
 Humans have emphasized more on the livestock farming and the waste produced after
digestion in livestock is a major source of methane gas.
 The use of fertilizers in the farming procedure has led to the increase in the nitrous
oxide level.
 The electronic products such as air conditioners emit Fluorinated gases that are used
to operate the products. These gases are over 23000 times harmful than that of the
Carbon dioxide emission in the atmosphere as these contribute in the warming effect
of the planet (Mu and et.al., 2020).
Effects of Climate change
 Biodiversity- The increasing temperature of the globe has resulted in disturbance of
the ecosystems and hence has a change upon the various reproduction processes of
living creatures on the planet. The scarce resources and the change in climate have
had impact upon the life habits of the various living species.
 Ocean- the global warming effect has led to the melting of ice in the region of poles
and thus has led to an increase in the sea level. The sea level has been rising at a very
fast pace which is a major threat.
 On Humans- Even the humans have not been unaffected by the climate changes. The
climate change has led to various imbalances in social, geopolitical and health
balances across the globe. Also there has been declination in the various resources
that have led to its scarcity.
 On weather- The weather has experiences a major effect of the climate changes. The
changes on weather have been really massive. The changes in weather have led to
serious conditions like floods, droughts and heat waves in various regions across the
planet. The number of natural disaster has been rising consistently such as storms,
hurricanes, forest fires, etc.
Recommendations to mitigate the effects
 Renewable energies- It is very important to switch upon the alternate to the fossil
fuels. Uses of fossil fuels have been depleting the nature as well as have effect on
environment too. The alternate sources to fossil fuels are wind energy, solar energy,
tidal and Hyde energies.
 Energy and water- It is very important to produce energy and those sources need to
produce clean energy without harmful emissions. People can switch to energy
efficient light appliances such as LEDs and waste saving techniques in order to save
water (Omer and et.al., 2020).
 Sustainable infrastructure- The people can shift upon the electronic appliances used
for heating or cooling the buildings which require lesser energy or are energy
efficient. These will help in reducing the carbon dioxide levels in the atmosphere.
These kinds of innovations are a need of the hour to mitigate the effects of climate
change.

 Sustainable transportation- The population can focus upon the various techniques to
promote sustainable transportation in the locality. People can switch to the hydrogen
mobility or electric transports that will have lesser impact upon the environment. Also
people must promote healthy habits like carpooling and use of public transportation
(Wu and et.al., 2020).
CONCLUSION
It can be concluded from the study that the climate has changed a lot in the last few
years. The change in climate is measured by the changes in the climate variables like wind,
precipitation, temperature and pressure. Climate is referred to the weather condition of a
region within a period of time. The study highlights the various causes of climate changes
and it also highlights the various recommendations to mitigate the climate change.
