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.
