Is Climate Change a Result of Human Activities?

This report analyzes the impact of human activities on climate change and global warming. It discusses the role of greenhouse gases, such as carbon dioxide and methane, and their increasing concentration in the atmosphere. The report also highlights the negative effects of human-driven climate change on biodiversity and species extinction.

Introduction
Human beings have increasingly influence the overall climate change on Earth’s warmth by
burning fossil fuels, farming livestock and cutting down of forest. It has added enormous amount
of greenhouse gases to the naturally taking place in the environment and also affected process of
global warming and greenhouse impact in long run (Dobrzinskij and et.al., 2021). Present report
is based on analysing the different situations of human activities that has resulted in to global
warming. Further, all these instances together are creating a difficult situation of frequent
climatic changes.
Main body
Scientists who are working on climate changes are comparing the climate pattern that the
observed with the patterns developed using several estimated models in the earth system. By
making a comparison between modelled and observed patterns scientist and optimistically
recognize various human fingerprints and for the characteristic the quantity of observing
warming process towards human activities. This fingerprints are establish in varied range of
records that a resulting from ocean earth surface and atmosphere. It basically includes increasing
level of carbon dioxide distinct atomic signature and unprecedented warming situation. All these
are left at the back in the atmosphere when fossil fuels are burnt resulting into rising carbon
dioxide levels (Li. and et.al., 2019). The above ground documents the carbon dioxide levels since
roughly 800,000 years ago starting in the 1760. There is a dramatic upwards by that is attributed
towards the industrial revolution. This data is compiled from the national oceanic and
atmospheric management and scripts of organization of oceanography.
The negative cost of human drive will persist to speed up the terrible impact on the external
environment (Tooley and Sheail, 2019) . The sea level is continued to rise and the foraging
habitat for Marine wildlife has lead to difficulty in survival of the marine life. All these indirectly
processor impact on the environmental functioning because human drive when climatic
transformation is a key driver of biodiversity disintegrate and extension of various class
(Rahimpour and et.al., 2021).
The overall atmospheric concentration of methane nitrous oxide and carbon dioxide has rise
around 200 years ago. All this is resulting into difficulty to manage the changes taking place in

the climate situation that arises mainly because of the recent global warming results from human
activities.

While all the observations are made as per the large scientific consensus it can be said that as per
the latest reports the intergovernmental panel on weather transformation is known over 95%
assurance that human activities have been the major causes of global warming. Normal climatic
cycles can modify the warmth but the change can be seen phenomenon at a scale & speed those
natural cycles cannot be explained. These cycles have affected the global temperature for years
and months (Zhang and et.al., 2021. There are long term changes like milankovitch cycles or the
solar irradiance that is also taking thousands of years. Apart from this there are many other
changes that are affecting the climatic change but the evidence is irrefutable. Human activities
like burning of fossil fuels have changed the mode land is used and is one of the foremost cause
of climate changes.
There are certain specific drivers of climatic change that may possess an impact on the
overall issues arising in the environment.

Carbon dioxide: carbon dioxide is shaped by majorly human activities and is one of the major
contributed towards global warming. In the coming year 2020, the concentration of atmosphere
has rise 248 % above the pre-industrial stage. Other greenhouse gases that are emitted by
individual activity in lesser quantity also affect the overall atmospheric conditions. Methane is a
powerful greenhouse gas as compared to carbon dioxide but it has a very short atmospheric
lifetime.
Apart from this there are neutral causes that include changes in the solar radiations are volcanic
activities that are found to do it towards plus or minus 0.1 degrees Celsius towards a total
warming between 1890 and 2010.
There are some of the causes that can lead to words rising of emissions.
Burning of oil and gas cool can produce nitrous oxide and carbon dioxide. Apart from this
cutting down of forest that is major human activities has led to impact on environment in a
negative manner that is adding to the greenhouse effect (Hsiang and Kopp, 2018). There is also
increasing livestock farming that is cows and sheep produce has led to large amounts of methane
while their digesting the food. Fertilizers that contain nitrogen produce nitrous oxide emissions
and for the flooring heated gases are also admitted from equipments that are using these gases.
These emissions have a very sturdy warming effect and are 23000 times superior as compared to
carbon dioxide.
Global warming: In the year 2011 to 2020 there is warmest climatic change that is recorded
where the global average temperature is reaching to 1.1 degree Celsius above the pre-industrial
levels in year 2019 (Asogwa and Onyegbulam, 2021). Human induce global warming is also
currently rising at a rate of 0.2 degree Celsius each decade.
The increasing 2 degree Celsius as compared to the temperature in pre industrial risk is
associated with serious negative impact on the human health and natural environment as well as
overall well being of people.
Human activates produce greenhouse gases in lot of different ways:
Deforestation: Forests are storing carbon dioxide from overall environment. Cutting down of
trees can lead to building up quicker since trees absorb it (Geng and et.al, 2020). For the trees
also liberate the carbon they are stored when they are burnt that results into increasing situation
of climate ham

Agriculture: rearing of animals and planting of crops also result into greenhouse gases into the
air. The main aspect is animals producing methane that is 30 times more influential than carbon
dioxide because of the greenhouse gases. The nitrous oxide that is used for fertilizers is very
worse and can lead to 300 times more potent as compared to carbon dioxide.
Human activities can be leading causes of climatic change is because of the human activity the
release of greenhouse gases and there are a lot of normal cause that can lead to change in the
climatic system. The natural cycles can lead to climate exchange between cooling and warming.
Natural factors are regarded as reports to climate change also regarded as forcing (Fatorić. and
Seekamp, 2017. These natural causes are contributing towards the climatic change as they are
not the chief cause but base on the scientific verification.
Solar irradiance: The changing energy from sun has lead to impact on the environment and
warmth of earth in the past few times. The increasing solar energy has created a situation where
the atmosphere of earth has become warm. The forming can be seen in the underneath layer only.
Volcanic eruptions: Volcanoes possess amazed consequence on the climatic change. Eruptions
have produced Arrow cell particles that is cooling earth but also releasing carbon dioxide that
warm set. Volcanoes are at reducing 50 times less carbon dioxide as compared to humans they
are not most important to major reason of global warming. But they are acting as a cooling
ingredient to reduce the dominant impact of greenhouse gases.

Conclusion
From the above discuss aspects it can be said that human activities consequence in emission
of four principal greenhouse gases that includes nitrous oxide, carbon dioxide, methane and
halocarbons. All these gases are accumulating in atmosphere that is leading to increasing
concentration with the time period. Carbon dioxide has increased from fossil fuels that are
resulting into heating and cooling impact on the external atmosphere. Nitrous oxide is also
admitted by human activities that are fertilizer use and fossil fuel burning which affects the
overall process of greenhouse gases resulting into globalisation and large amount of climatic
changes.
