The Role of Human Activities in Driving Global Climate Change

This essay examines the relationship between human activities and climate change, asserting that increased gas concentrations in the atmosphere, particularly since the industrial revolution, are largely due to human actions. It highlights the role of fossil fuel combustion, deforestation, and cement manufacture in increasing CO2 emissions. While natural factors like volcanic eruptions and solar variations also contribute, the essay emphasizes that human-induced greenhouse gas emissions, especially CO2, have had a dominant warming effect. Climate models support the conclusion that the warming observed over the past 150 years is primarily driven by human activities, outweighing natural influences. The essay also notes the impact of human activities on land cover and the release of other greenhouse gases like nitrous oxide and halocarbons. Ultimately, it concludes that human actions are the primary cause of global warming since the 20th century, with farming, livestock, and deforestation contributing significantly to the increase in greenhouse gas concentrations.

‘Is Climate Change a result of human activities?
Human Activities have nowadays has res in the increases in the gas concentrations in the
atmosphere. The nitrous, atmospheric concentrations of the carbon dioxide, methane and oxide
has began to increase approximately two hundred years ago with the change. In context to Co2,
there has been a continuous process of exchange among the die and decay, land and oceans, land
and marine plants grow (Maunder, 2019). Since the 19th century, the human induced C02
emissions from deforestation, fossil fuel combustion, cement manufacture have resulted in
creating a disturbance. In addition to that it has been observed that the recent case of global
warming resulted from the human activities. The cooling and climatic warming also arises from
the various changes in the flow of energies within the system change in climate (Powers, and
Jetz, 2019).The major drivers which resulted in last century involves volcanic eruptions,
increases in atmospheric C02 , change in the brightness of the sun, replacement of the darker
forests with grasslands and paler croplands, increase in tiny particles in the atmosphere.
Moreover, the changes in the greenhouses gas concentrations was dominated by the C02 that
lead to causing a large warming contribution. In addition to that as compare to other influences,
the effects of the solar variations is based on present warming are small. In addition to with the
use of climate models it was possible to divide the effect of the human induced and natural
influences on the climate.
With the use of climate model it can easily reproduce the warming in the last 150 years
which basically involved human and natural influence but not in the situation natural influences.
It also has been observed that global warming resulted from humans rather than natural
consequences. In context to human activities, it had contributed towards the climate change with
change that caused in the atmosphere of the earth that involved the cloudiness, greenhouse gas
and small participles (Thaler and Fuchs, 2020). The largest and the biggest contribution arises
from the fossil fuel’s burning that basically releases the gas of carbon dioxide to the atmosphere.
The aerosols and greenhouse gases affects the climate with alteration of the incoming of the
solar radiation and outgoing of the thermal radiations. With the change in the abundance and
properties of the particles and gases that can lead and result in cooling or warming of the climate

system. With the ear of the industrial industries and era there has been a overall effect and
influence of the human activities had a major impact. The human influence on the climate around
this industrial area has resulted in exceeding due to natural processes’ changes that involves
volcanic eruptions and solar changes. The human activities result in emissions of the four
principles of green house gases that involves the halocarbons, carbon dioxide, nitrous oxide and
methane. All these gases accumulates in the atmospheres that results in causing the
concentrations to increase within the time period. There also has been a significant increase in
the gases which occurs in the era of industries and all these has resulted in increasing the
attributes of the human activities( Nicholson, 2018). Moreover the carbon dioxide has resulted in
increase from the fossil fuel use in the manufacture of the cement, transportation, manufacture of
other goods and building cooling and heating. The another gas nitrous oxide has been also
emitted from the human activities that involves burning of the fossil fuel and fertilizer use and
also involves the natural processes in the oceans and so is and also release of the N20. Another
gas like halocarbon gas concentrations have also increased because of the primary reason of
human activities.
Human activities since the era of industries have changed the nature of the land cover
around the world and over the globe. Also the scientists have agreed that the main reason of
global warming is because of the human activities and human. Moreover, the evidence shows
that there has been a involvement of heat trapping gases that also involves the carbon dioxide
and also release of the harmful gases through burning of the fossil fuels such as gas, coal and oil(
Alvares, Sentelhas and Stape, 2018).The carbon dioxide gas is the major cause of increase in the
level of heat trapping gas in the atmosphere as compare to the data of the past several decades. It
had been also noticed that the major and the dominant cause of the global warming since the 20 th
century is the activities of humans. There has been a constant increase in the influence and
impact created by the humans and also there has been a major influence on the temperature of the
earth with farming livestock, burning of fossil fuels and cutting down the forests. It also resulted
in adding a enormous amounts of the greenhouse gases to gases naturally occurring in the
atmosphere with the increasing in the global warming and greenhouse effect. Humans and their
activities in daily lives have a major impact on the climate and the surroundings.
