PROJECT WORK ON GLOBAL WARMING
INTRODUCTION:
Global warming has
emerged as a major problem which the whole world is facing today
Its consequences can
prove dangerous not only for us but also for our future generations
I have chosen this
project to warn people of the ill effects of global warming
So let’s understand
what is global warming
What is global warming?
Global warming is the
increase of average world temperatures as a result of what is known as the
greenhouse effect. Certain gases in the atmosphere act like glass in a
greenhouse, allowing sunlight through to heat the earth's surface but trapping
the heat as it radiates back into space. As the greenhouse gases build up in
the atmosphere the earth gets hotter.
This process is leading to a rapid change in climate, also known as
climate change.
IMPORTANCE:
Global warming is
important since it helps determine future climate expectations. Through the use
of latitude, one can determine the likelihood of snow and hail reaching the
surface. You can also be able to identify the thermal energy from the sun that
is accessible to a region. Global warming is the scientific study of climates,
which is defined as the mean weather conditions over a period of time. A branch
of study within atmospheric sciences, it also takes into account the variables
and averages of short-term and long-term weather conditions. Global warming is
the unequivocal and continuing rise in the average temperature of earth's climate
system. Since 1971, 90% of the warming has occurred in the oceans. Despite the
oceans' dominant role in energy storage, the term "global warming" is
also used to refer to increases in average temperature of the air and sea at
earth's surface. Since the early 20th century, the global air and sea surface
temperature has increased about 0.8 °c (1.4 °f), with about two-thirds of the
increase occurring since 1980. Each of the last three decades has been
successively warmer at the earth's surface than any preceding decade since
1850. Global warming uses from omits group are an open access journal named as
journal of climatology and weather forecasting which strives to release issues
quarterly and is adamant to publish new findings related to the field of global
warming. The mission of the global warming uses provides a forum for publishing
new findings on environmental principles and technology. Currently our primary
research objective is to encourage and assist the development of better and
faster measures of environmental activity. In cases where we believe we can
contribute directly, as opposed to through highlighting the work of others, we
are producing our own measures of global warming.
OBJECTIVES
To work for
protecting and promoting healthy natural environment through various action programmers
and environment awareness creation among and education of the people.
To work for healthy,
neat and clean cities and urban environments
To work for
environment health of workers.
To work to prevent
excessive exploitation of natural resources and energy sources.
To work for creation
of new environment education programmers to sensitize the young generation
about the importance of environment and environment protection and to
incorporate environment sensitivity in the socialization process of the growing
up individuals.
To work for the
welfare and human development of the vast sections of Indian population who
have not come to the modern levels of advancement socially, educationally and
economically, by undertaking social, educational and economic empowerment
activities, advocating and campaigning for policies to bring about social,
educational and economic empowerment of all sections of society.
To work for widening
science and technology among the rural, tribal and other disadvantaged sections
of society.
To organize health
and medical camps with a view to reaching health and medical care to the
general masses, especially the disadvantaged sections of the Indian people like
the scheduled castes, scheduled tribes, socially and educationally backward
classes who are also referred to as other backward classes, minorities,
female-headed households, handicapped people, mentally challenged persons,
destitute women and children.
To work for
rehabilitation of victims of environment disasters.
To work to reach
justice to all sections of society, especially the disadvantaged sections,
namely, scheduled castes, scheduled tribes, socially and educationally backward
classes, religious minorities, etc.
To work for equipping
the general masses of Indian people with the modern technical and professional
skills in the areas of communication and information technology.
To work for imparting
occupational skills and upgrading skills of workers and professionals with a
view to making all Indian people capable of competing for suitable employment
opportunities at international level.
To work for
rehabilitation of emigrant and displaced Indians; to study their social,
cultural and economic issues and to work to get them rehabilitated back into
the homeland.
METHODOLOGY:
This project is
completely based on research done by me on the internet as during the pandemic
It is not possible to
go out and do research
I have obtained
information from the following websites
https://climate.nasa.com
Www.wikipedia.com
Www.nrdc.com
Www.nationalgeographic.com
Www.org.au
OBSERVATION:
We have lot of
observations of the earth surface warming during the last few decades. Surface
temperature measurements over land and ocean, satellite measurements, weather
balloon measurements, ocean temperature measurements and borehole measurements all
show clear increase in the average temperature of the earth. Supporting these
are the indicators of warming, such as changes in the behaviour and ranges of species,
melting glaciers, rising sea level, vanishing sea ice etc.
Main causes of global
warming
Burning fossil fuels
Deforestation &
tree-clearing
Agriculture &
farming
Travel & transportation

ANALYSIS:
Causes for rising
emissions
Burning coal, oil and
gas produces carbon dioxide and nitrous oxide.
Cutting down forests
(deforestation). Trees help to regulate the climate by absorbing CO2 from the
atmosphere. When they are cut down, that beneficial effect is lost and the
carbon stored in the trees is released into the atmosphere, adding to the
greenhouse effect.
Increasing livestock
farming. Cows and sheep produce large amounts of methane when they digest their
food.
Fertilizers
containing nitrogen produce nitrous oxide emissions.
Fluorinated gases are
emitted from equipment and products that use these gases. Such emissions have a
very strong warming effect, up to 23 000 times greater than CO2.
CONCLUSION:
What is the
conclusion of global warming and climate change?
Human-induced climate
change has contributed to changing patterns of extreme weather across the
globe, from longer and hotter heat waves to heavier rains. From a broad
perspective, all weather events are now connected to climate change.
The 'Conclusion'
confirms that global warming is the major challenge for our global society.
There is very little doubt that global warming will change our climate in the
next century. ... If implemented now, a lot of the costs and damage that could
be caused by changing climate can be mitigated.
