INTRODUCTION
Climate change describes as long-term shifts in the weather and temperatures patterns.
These shifts may be occurs through natural activities like variations in the solar cycle or through
some human activities such as burning of fossil fuels like oil, gas and coal. The human activities
are considered as primarily action that create change in the climate. The following essay is
prepared for the topic of “to what extent is Climate Change a result of human activities?”.
MAIN BODY
Most of the scientific activity are believe that there are many human induced activities tat
are significant contributor in changing the levels of global carbon dioxide and climate. Carbon
Capture and Storage is a process where CO2 is captured through hydrocarbon based power plant
as well as other point of sources as well as subsequently stored in deep saline water bearing rock
formations which represents a promising mitigation strategy (Cook and et. al., 2013). There are
many human activities which affecting the climate which includes combustion of fossil fuels that
are altering the climate system. Humans are also creating changes in land cover and land use
which includes urbanisation, deforestation as well as shifts in vegetation patterns which also
change the climate which results in alteration in reflectivity of the earth surface, urban heat
island effects, emissions from burning forests as well as changes in the water cycle. All these
activities of the human creating the changes the environment which results global warming due
to which their life are also affects. This makes important for the human in order to understand
how the some activities conducted by them affecting the climate and environment due to which
their life also get dangerous.
Changes in solar radiation, in the atmospheric, abundance of greenhouse aerosols and
gases as well as in land surface properties create alternation in the energy balance of the climate
system. These changes are also be considered as radiative force that are used to compare how a
level of natural and human factors create cooling or warming influences of the global climate.
The TAR, new observation as well as related modelling of the greenhouse gases, land surface
properties, solar activity and some other factors of aerosols can help in improving the effect of
radiative forcing in better manner (IPCC, 2007). The most important anthropogenic greenhouse
gas is carbon dioxide. It has increased to 280 ppm to 379 ppm3 a pre-industrial value in 2005
which was exceeds by the far natural range as which was determined through ice cores. In

overall increase in carbon dioxide it create changes in the climate as it cause many problems for
in the environment such as global warming and many more which does not affects the natural
beauty of the place as well as it become more dangerous for the common life of people in order
top survive it in effective. As these changes in the climate created by the natural and human
activities. Natural activities are not to be changed or stop but the activities which is created by
the human can be stop or reduced in order to reduced its affects on the climate in better manner.
The General Circulation Models is important as it provide regional impacts on the
anthropogenic greenhouse gases like increase in carbon dioxide. It is important to take validation
from the GCMs for the quantification of anthropogenic CO2 forcing impacts and their
connection to the global warming along with other natural and human factors that force climate
change. It is also important for the reduction of common deficiencies to stimulate crucial
variables of the climate (Soon and Baliunas, 2003). Basically GCMs are described as computer
based model which is used to forecast weather, understand the climate as well as projection of
climate change. This basically help in understanding how the natural and human activity are
affecting the climate. This will helps in altering people about the changes in the climate which
helps in understanding people to know that climate are changing rapidly due to certain activities
performed them. This makes people to stop and make reduction in their activities in order to
prevent climate from the change.
Arctic sea ice extent to melt in the end of September but it had declined sharply from
1953 to 2006. Because of the loading on atmospheric greenhouse gas the Arctic sea ice extent
will decline in 21st century. By fostering large heat fluxes to the atmosphere as well as delaying
winter and autumn ice growth will promote the increases in the air temperature of the surface of
the Arctic Ocean that are considered as outsized while comparing with the whole globe. Due to
loss in ice it affects mid-latitude patterns of atmospheric precipitation and circulation (Stroeve
and et. al. 2007). Due to increase in global warming, it cause climate change and it results in
rapidly decline in Arctic Sea ice. The global warming is increased due to certain activities of
human as it affects the nature of the world. This is also make important for the humans to stop or
decreases doing certain activities which creates changes in the climates and various other
problems are also get affected due to this.
The climate changes on different timescales, but the main factor of change is humans as
well as they are like to be remain so for the next few centuries. The climate change which is

induced by the human caused global warming. This will directly influenced on drought, heavy
rainfalls as well as storms and it greatly affects the environment and society in effective manner.
In between 5 to 15 % climate change are modest after it limit crossed things are break down as
well as damages increases non- linear manner (Trenberth, 2018). These are not properly affects
the climate change as well as it prepare for the expected effects which is exacerbating damage
and woefully inadequate issues. The activities that are performed by the human are increase the
carbon dioxide as well as other heat-trapping greenhouse gases which create change in the
composition of the atmosphere which results in global warming.
CONCLUSION
From the above mentioned report, it has been concluded that that activities that are
performed by the humans will affects the climate in order to change. The change in climate cause
global warming which also affects the environment and place of the country. The Arctic sea ice
is also declining fast from the last few years due to global warming.
