The Role of Human Activities in Climate Change: An Environmental Study

This essay examines the profound impact of human activities on climate change, highlighting the role of greenhouse gases emitted from burning fossil fuels, deforestation, and industrial processes. It discusses the five major climate zones and how human actions exacerbate global warming, leading to consequences like rising sea levels, droughts, and floods. The essay also explores potential solutions, such as transitioning to renewable energy sources like solar and wind power, and emphasizes the urgency of reducing emissions to limit global temperature increases. The report concludes that mitigating climate change requires significant changes in human behavior and substantial investment in sustainable practices, with resources like Desklib providing valuable support for students studying these critical issues.

ESSAY

INTRODUCTION
The general Weather conditions of a particular location where conditions includes the
temperature, wind, storms, rainfall, etc. Global climates are separated into five categories.
Firstly, the tropical regions which have high average temperature and heavy amount of rainfall.
Example- Malaysia, Indonesia etc. Secondly, temperate region which have little amount of
rainfall but summers are tend to be quite warm. Example- Rome, cape town etc. Thirdly, the
polar regions consist of floating and pack ice. Example – arctic ocean etc. Fourthly, dry regions
with very little rainfall. Example- Sahara Desert, Sonoran Desert etc. Lastly, the cold regions
which have high seasonal variations in temperature. Example- Siberia, Greenland etc. This
division of climate is known as open climate classification system which is named after founder
Vladimir koppen (Nabil, Gustafson and Jensen, 2018). The below report is based on the human
activities which is affecting the climate severely.
TASK
Climate Change a extent result of human activities-
Climate change basically for long period shifts in the weather, temperature patterns.
which can occur by nature through variations of solar cycle. The climate is mostly affected by
the parallel, earth's alliance, movement of winds, the differences in sea, land and topography,
changes in orbit of earth, sun, plate geomorphology. But the main driver of climate change is the
activities done by Human related to the diminution the layer of ozone and the lack of fossil fuels
were burning includes gas,oil and coal which may lead to greenhouse effect. Burning the fossil

fuel generates greenhouse gas which is similar as a blanket around earth which traps the raising
heat and temperatures of sun. Humans have a big contribution in changing of the climate, since
the beginning of the industrial era there has been the warming influence and The impact of this
era is greatly exceeding. These activities result in four greenhouse gases which includes nitrous
oxide, methane, carbon dioxide, and the halo-carbons.
Dioxide Carbon gas has been increased by due to use of fossil in transport, cooling and
heating and manufacture of the cement as well as other. This gas is also released due to the decay
of plant matter and deforestation which reduces the uptake by plants.
Methane gas is also increased due to human activities related to landfills and agriculture. For
instance, in wetlands growth rates has been decreased over the last two decades and because of
this methane concentration has been reduced in the atmosphere (Beekaroo, Callychurn and
Hurreeram, 2019).
The nitrous oxide is emitted by the natural processes in soils like fertilizer use etc. and
the ocean also release the N2O.
The halo-carbons gas concentrations have been increased majorly by the humans. Halo
carbons include the chlorofluorocarbons which is used as refrigeration agents and in the other
process of industry. But before their presence was found in atmosphere to cause depletion of
stratospheric ozone. The chlorofluorocarbons gases have been decreasing now as international
regulations decided to protect the ozone layer. Usually the main emitters of these gases are
energy, Industry, buildings, transport, and agriculture.
1. Apart from these four gases there are two more things included in the greenhouse effect.
One of them is water vapour. A warmer conditions contains more water and the human
activity determinant the water vapour through CH4 emissions, which is caused due to
chemical destruction in the stratosphere. And the second one is the aerosols, which are
the little particles in the atmosphere with widely size, concentration and chemical
composition. They contain both naturally compounds as well as the compounds which
are emitted by the activities of humans. Natural aerosols include the mineral dust, sea salt
aerosols and volcanic eruptions. The aerosols emitted by the activities of humans are
surface mining and industrial processes. trees and forests degraded or completely cleared,
then they stores carbon which helps to be return into the condition as dioxide and also
contribute into change of climate. Scientists have recognised that if the forests get

protected from fire or any other vanishing activity then it would be helpful in tackling
climate change. the heat produced by the production of electricity emits the large amount
of CO2 and Some methods of production of electricity which produce no or few CO2
emissions includes geothermal, solar, wind, hydro power, and nuclear systems as
particularly. If the harvesting happened to generate fuel for the electricity, and not
replaced then global climate change could be expedited. Plastic is also the component
implicated in climate change (Barletta, Lima and Costa, 2019). Plastic is generated by use
of materials like propylene and ethylene which is made by fossil. The operation of
transporting fossil, then manufacture the plastic which creates the billions of gases of
greenhouse. For instance, annual petroleum industry by 4 percent of the world are
pleased to making of plastic, and other percent gets burned into the process of refining .
Now the heat and sunlight caused to the plastic to accomplishment the gases of
greenhouses, which is leads to an loop. changes of climate, change our planet like planet
gets more hotter, and the plastic breaks out into more ethylene & methane, which helps to
increase the rate of climate change. Global warming also changed the climatic conditions,
there are droughts somewhere and somewhere floods, this climatic imbalance resulted in
global warming. Also, the volcanoes are the natural contributor of climate change as they
emit smoke during the eruptions which goes directly to the atmosphere and effects the
climate. Scientists and government suggested agreed that rising of limiting global
temperature into 1.5 degree Celsius to avoiding the worst conditions of climate and
maintain the liveable climate. If this is not controlled then Humans would have to face so
many consequences like rising of the sea levels, water deficiency, flooding, polar ice
melting, fires, and so on of change of climate(Clayton and Radcliffe, 2018). This change
can affect the humans severely on their health, ability to grow food, etc. there are Many
solutions for change of climate which can give the benefits of economy for improving the
lives and protect the nature. The systems switching from fossil to renewable with wind
which can decreasing the changes of emissions driving of climate that will be required
the financial investments by governments and organisation. But it is to be started from
this point. When the countries growing organisation in 2050 has no emissions, and to cut
emissions into half which is placed by in 2030 to below warming at 1.5°C. The

production of Fossil require to decrease by 6 percent per annum roughly by 2020 and
2030. so humans are only one who can improve and control it to have a better future.
CONCLUSION
Summing up all the advantages, disadvantages, problems and solution, the conclusion of
this report is that the global climates are separated into 5 parts like polar, temperate, cold, dry
and moderate. The major climate change is causing by the burning of fossil fuels like coal, gas,
oil, and transport, building heating, land filling, agriculture, fertilizers, plastic, eruptions and
many more which is producing the harmful gases of greenhouses which includes nitrous oxide,
methane, and dioxide, and the halo-carbons. the human activities and actions are the major
problem of climate change rather than the natural causes. As the global warming is increasing
day by day There will be some consequences which had to be faced by the humans like droughts,
floods etc. if they did not control the activities which are harming the climate. Switching up
recent energy systems to solar or wind will help a lot in bettering the climate conditions.
