Analyzing the Extent of Climate Change Due to Human Activities

This report examines the extent to which climate change is a result of human activities. It highlights how various human actions, particularly the combustion of fossil fuels and deforestation, contribute to the emission of greenhouse gases, leading to alterations in the Earth's atmosphere and energy balance. The report details the impact of greenhouse gases like carbon dioxide, methane, and nitrous oxide, as well as aerosols, on radiative forcing and climate warming. It also discusses the role of industrial activities, land use changes, and natural factors such as solar changes and volcanic eruptions in influencing climate patterns. The analysis concludes that human activities significantly exacerbate climate change, necessitating strategies to mitigate these environmental impacts. Desklib offers this report to aid students, providing a clear understanding of the complex relationship between human actions and climate change, and serves as a valuable resource alongside other study tools like past papers and solved assignments.

INTRODUCTION
Climate change is defined as the long-term shift in weather as well as climate temperature
pattern. Human activities are considered as the various actions for reactions that are done by the
human being (Asch, et. al. 2018). There are various human activities that impact the climate and
weather conditions in negative manner such as combustion of fossil fuel that altering climate
system. There are some human-driven changes that affect environment and its conditions. It is
important to take efficient actions and develop strategies to reduce these impacts on
environment. this report covers the extent that explains how human activities impact on climate
conditions.
MAIN BODY
Climate changes is causing due to contribution of human activities that leads to changes
in atmosphere of Earth in form of greenhouse gases, aerosols as well as cloudiness. It is a results
from burning of fossil fuels that releases different gases like carbon dioxide gas to atmosphere.
There are some other factors that also create impact over climate like Greenhouse gases and
aerosols that effect climate through alteration in incoming solar radiation as well as outgoing
infrad radiation (Child, et. al. 2018). It is a part of energy balance of earth. Changes occur in
atmosphere abundance as well as properties of parties and gases leads to warming or cooling in
climate system. Industrial era has started in the year 1750 and after that impact of human
activities has stated to influence over climate. Impact of human activities on climate is increase
that also leads to changes in natural process like solar changes, volcanic eruption.
Green House gases : Human activities in business also results in emission that is based on
different green house gases including carbon dioxide, nitrous oxide, methane as well a
halocarbons. All these gases can be accumulated in atmosphere that cause concentrations that
increase with time (Kasperson, et. al. 2022). There is increase in different gases which is
occurred during industrial era. There is increase in carbon dioxide due to increase from fossil
duel used in building heating, cooling, transportation as well as manufacturing of different
goods. Deforestation is also a factor that releases CO2 and contribute to reduce uptake through
plants. Release of carbon dioxide is also a component that take place in natural process like
decay in plant matter.

Release of Methane gases is also increase due to human activities that is related to
landfills, agriculture and natural gas distribution. It is a result of natural processes that occur due
to wetlands and other things. There is no increase in methane concentrations in present time in
atmosphere as growth rate is also decreased. Release of Nitrous oxide is also done due to human
activities like use of fertilizer, burning of fossil fuel and others. This N2O is lass release due to
natural process in oceans and soils (Visschers, 2018). Concentration in Halocarbon gas is also
increased from human activities. Natural process is also considered as small source of
halocarbon gas. Principle halocarbon is also including chlorofluorocarbons that is used
extensively as refrigeration agent as well as industrial process.
Ozone is considered as greenhouse gas that produced and destroyed in continuous
process in atmosphere through chemical reactions. In troposphere layer, human activities has
also increase through related of different gases like hydrocarbons, monoxide and nitrogen oxide
that react to ozone. Hydrocarbons is one that release through human activities and destroy ozone
in stratosphere and also cause ozone hole in Antarctica.
Water vapour is also a most important greenhouse gas present in atmosphere. Human activities
also create direct impact over atmospheric water vapour. Humans indirectly has potential to
create impact over water vapour through changing climate.
Radiate forcing of factors affecting human activities: Radiate forcing is contributing to
different factors that can be influenced by human activities. There are different values that can be
reflect from total forcing in relation to industrial era. There is also increase in different types of
green house gases that can be understood by human activities and are positive as all these gases
can be absorbs through outgoing infrared radiation in atmosphere. There is increase in Co2 gases
which is a part of green house gases and also causing largest force over a certain period of time.
Increase in tropospheric ozone also contributing to warming whereas decrease in stratospheric
ozone also contributing to cooling (Watson, 2018). Aerosol particles also create influence
through reflection as well as absorption of solar that infrared radiation into atmosphere. There
are some aerosols that cause positive forcing to others and cause negative forcing. It radiative
forcing is creating impact over type of aerosols which is a negative. There are also different
types of human activities also takes place in industrial era that is different from nature of land
and cover all over globe through changes in forests, croplands, pastures. Modification also have
occur in reflective properties of snow and ice. There is more solar radiation is reflected from

surface of earth that is a result of human activities and all these changes result in negative
forcing.
Aircraft also produce stable linear trails in condensation in regions that consist high
humidity and low temperature. Contrails is a types of cirrus cloud which show solar radiation as
well as absorb infrared radiation. There is also increase in linear contrails from global operation
of aircraft that increase cloudiness oner earth and is create positive radiate forcing.
Radiative forcing from natural changes: Due to various changes in solar and explosive
volcanic eruption, natural forcing occur. There is increase in solar output gradually in industrial
era that cause positive radiate forcing. It results in addition to cyclic changes in solar radiation
which follow cycle of 11 year. Solar energy is also creating heat in climate system and also
affect atmospheric abundance related to some greenhouse gases like stratospheric ozone. There
is also explosive volcanic eruption can also occur that create negative forcing thorough
temporary increase due to sulphate aerosol in atmosphere. Explosive volcanic eruption is also a
things that create negative forcing that can be through temporary increase in sulphate aerosol in
stratosphere.
CONCLUSION
From above mentioned project report, it can be concluded that climate changes is one of
problem occur for people as due to this changes in temperature is also occur. All these changes
can be occur due to human activities. Human are involved in different industrial and
manufacturing industry which create negative impact over climate. It cause release of different
harmful gases in environment that also create impact over ozone layer. In order to overcome of
this problem, it is essential for people to control impact of human activity of climate which is
essential for them.
