Chapter 1
INTRODUCTION TO GLOBAL WARMING: IT’S INDUCING FACTORS
1.1 Prelude:
Most of the information available on global warming is subject to contradictions –
contradictions that lead to differences of opinion between what and who is correct. As all
reports on global warming are not considered authentic (some are considered as emotional
outbursts, while some are regarded as skewed), exchange of dialogue, views and expectations
in the context of global warming gets meatier and perplex not just nations and their economy
but also affect the geographical, anthropological, sociological and psychological systems and
structures that exist today.
Impacts of global warming stand galore. The World Health Organization, United Nations
Environment Programme and the World Meteorological Programme observe that each year
more than 1, 50,000 people succumb on grounds associated or linked to global warming1. In
recent years, nature has witnessed several disasters, ranging from floods in Yugoslavia,
Romania, Serbia and Bulgaria to droughts in Sahel in Africa, from hurricanes in United
States of America to forest fires in diverse regions of the world such as Australia, Greece,
Spain and Portugal, from melting of Arctic glaciers and Antarctica ice-sheets to melting of
permafrost2. All such natural catastrophes leave profound impact on the diverse components
of nature. Loss of species, migration of species, change in the breeding seasons of animals,
shift in the growing seasons of plants, spread of diseases such as chickenguniya, malaria and
encephalitis, violation of human rights, etc. are some of the expressions of such catastrophes.
Such damage and destruction encompassing the subject of global warming poses certain
pertinent questions before us like:
1 http://www.guardian.co.uk/environment/2003/dec/12/climatechange.climatechangeenvironment
2 http://www.rupe-india.org/mail.html
2
1. Are we enduring such impacts due to the current emissions of greenhouse gases?
2. Is it global warming that is responsible for such impacts?
3. Is global warming an environmental change that has to be faced by us because of
industrialization?
4. Finally, if all the questions mentioned hereinabove are answered in the affirmative,
what legal regime exist at the international and national levels to tackle such issue and
what else can be undertaken to resolve the said crisis?
1.2 Definition of the term “Global Warming”:-
The Earth’s climate continuously changes following a natural process. It is as a consequence
of such natural process that the ice-cold climate of the Earth became favourable for the
evolution of mankind. The solar energy that passes through the Earth’s atmosphere is
absorbed by the surface of the Earth while a major portion of it is reflected into space. This
process, if continued naturally, would not have disturbed the atmosphere of the Earth and
hence would not have become a cause of concern. However, with industrialization,
overpopulation, land-use change, deforestation and change in lifestyles, the concentration of
the different gases present in the atmosphere have undergone change. Some of such gases
like carbon-dioxide, nitrous oxide, methane, etc., create a partial blanket over the Earth’s
atmosphere and do not allow the outgoing infra-red radiations to travel back into space. They,
in turn, trap the infra-red radiations and reflect them into the Earth’s atmosphere. This
mechanism of trapping gases is mostly adopted in greenhouses to take aid of the warmth
generated from such gases in the quicker growth of plants present therein. As the mechanism
involved is similar to what is deliberately done in a greenhouse, such effect in the Earth’s
atmosphere is known as the ‘Greenhouse Effect’. As a consequence of the greenhouse effect,
the global mean temperature of the Earth increases. Such increase in temperature continues
3
over a long period of time and is the main cause of extensive warming of the planet and
hence termed as ‘Global Warming’. The fallacy here is that warming of the Earth is necessary
to make it habitable otherwise the Earth would be a big ball of ice, non-conducive to life, but
such warming should be following the natural cycle. When the increase in the concentration
of the greenhouse gases happens irrationally due to human induced activities, the enhanced
greenhouse effect occurs and hence global warming.
The emission of the greenhouse gases has been on the rise since pre-industrial times but such
increase has become extensively rapid in recent times with the advancement of science and
technology, the increase in the burning of fossil-fuels and land use change. It may be
observed herein that the Fourth Assessment Report of the Intergovernmental Panel on
Climate Change published in 2007 has stated that the increase in the global greenhouse gas
emissions has been up to 70% between 1974 and 20063.
Apart from the naturally occurring greenhouse gases namely carbon-dioxide, methane and
nitrous oxide, there are certain other man-made greenhouse gases like chlorofluorocarbons
(CFCs), per fluorocarbons (PFCs), hydrofluorocarbons (HFCs) and sulphur hexafluoride
(SF6). Increase in the concentration of such man made gases further enhances the average
temperature of the Earth and causes the enhanced greenhouse effect. When the increase in the
stock of the greenhouse gases goes beyond the carrying capacity or the assimilative capacity
of the Earth, there occur manifestations of the same through changes in the weather regime
and impacts are also observed on the diverse ecosystems of the globe.
1.3 Global Warming - Relationship with Climate Change:
The Synthesis Report of the Fourth Assessment Report on Climate Change published by the
Intergovernmental Panel on Climate Change in 2007 clearly establishes the fact that global
3 Climate Change: Challenges to Sustainable Development in India, Rajya Sabha Secretariat, New Delhi, 2008,
Occasional Paper Series (3)
4
warming is occurring at an alarming rate which is observable from the increase in the average
air temperature and ocean temperature, the widespread melting of ice-sheets and the rise in
the sea-levels. The Third Assessment Report of the Intergovernmental Panel on Climate
Change, published in 2001, established the fact of climate change and stated that it is beyond
the ‘normal’. Climate change refers to the changes brought about in the Earth’s climate
system over a wide period of time taking place mainly by human intervention or more
specifically, human induced global warming. Article 1 of the United Nations Framework
Convention on Climate Change defines ‘climate change’ as “a change which is attributable
directly or indirectly to human activity that alters the composition of the global atmosphere
and which is in addition to natural climate variability observed over comparable time
periods”.
Interpretation of such definition implies the following:
a) That human induced activities are primarily responsible for climate change;
b) That climate change brings about a change in the composition of the global
atmosphere, i.e., a change in the acceptable concentrations of gases in the
atmosphere;
c) That it is not naturally induced.
It has however to be kept in mind that all the impacts observed are not due to the current
emissions of greenhouse gases but a result of the cumulative impact of such emissions that
have happened since pre-industrial times. The temperature of the earth has already increased
by 0.8 degrees Centigrade since the Industrial Revolution4. With the current trend of global
warming, it is expected that there would be a further increase of about 0.7 degrees
4 Climate Change:Challenges to Sustainable Development in India, Rajya Sabha Secretariat, New Delhi, 2008,
Occasional Paper Series (3)
5
Centigrade5. This means that in the recent future, there would be a total rise of about 1.5
degrees Centigrade even if we manage to arrest global warming today6.
1.4 Understanding Greenhouse Gases:
The major greenhouse gases traced till date include carbon dioxide, methane, nitrous oxide,
per fluorocarbons, chlorofluorocarbons, hydrofluorocarbons, etc. A deeper understanding on
these gases will help us in understanding global warming in a much better way.
I. Carbon dioxide (CO2): Of all the greenhouse gases, carbon dioxide is regarded as
the most significant contributor to global warming. It is the increase in the
concentration of the said gas that causes the maximum climate variability and climate
change. The pre-industrial concentration of carbon-dioxide was 280 parts per million
(ppm)7 while the said concentration rose to above 350 ppm in 1998
8. It has been
projected that with the current trend of increase in the concentration of carbon-
dioxide, the concentration of the said gas will be anything close to 500 ppm9 by the
end of the twenty-first century. Out of the six major identified greenhouse gases,
carbon dioxide has the highest lifespan of close to thousand years. Of this, about half
remains in the atmosphere for almost a hundred years scenario. Carbon dioxide is
generated through multifarious activities ranging from plant and animal exhalation to
volcanic eruptions and oceans, from decaying of plants and animal bodies to the
burning of fossil-fuels. It is said that most of the world’s economy runs on carbon and
hence with the burning of the fossil fuels, the concentration of carbon-dioxide is
constantly being liberated. In industrialised nations, coal, petroleum and natural gas

concentration-emissions-climate 9 Patwardhan Anand, ‘Global Warming and India’, Seminar486-February 2000, Pgs. 63-67
6
are responsible for carrying out the major portion of the industrial functions and hence
the emission of carbon-dioxide is always on the rise. One of the other reasons for the
increase in carbon dioxide concentration in the atmosphere is the change in the land
use patterns which are constantly happening either to provide land for the burgeoning
population or to make way for biofuels production, little realising the fact that while
trying to reduce greenhouse gases, there is occurring an increase in the concentration
of such gases.
II. Methane (CH4): Methane is the second most noteworthy contributor towards global
warming. Being a hydrocarbon gas and having over a hundred year’s lifespan, it is
considered to be 21 times more damaging than carbon-dioxide by weight10
but its
availability in the atmosphere is less as compared to carbon-dioxide. Methane is very
readily available from manure of domestic livestock. Again, while digesting the grass
accumulated while grazing, the cattle exhale the poisonous gas, methane. Methane is
also a by-product of rice production and is found when organic matters decompose in
swamps. It is also obtained in the guts of termites and cud-chewing animals. It has
been observed that with each passing year, the concentration of methane in the
atmosphere is growing by about one percent11
. It has been observed in the Synthesis
Report of the Fourth Assessment Report of the Intergovernmental Panel on Climate
Change published in 2007 that the atmospheric concentration of carbon dioxide has
increased to 379 ppm in 2005 while the concentration of methane has shot up to 1774
parts per billion (ppb) in the same year12
. Such increase bypasses the natural range of
such gases over the last 650,000 years13
.

III. Nitrous oxide (N2O): It is also another powerful greenhouse gas that is liberated into
the atmosphere through practices adopted in soil cultivation especially when organic
pesticides and fertilizers are used in farming activities. Biomass burning and fossil
fuel combustion also increase the concentration of nitrous oxide in the atmosphere.
The pre-industrial concentration of nitrous oxide in the atmosphere was found 0.27
parts per million14
by volume which has stealthily risen to 0.31 parts per million by
volume in 1998. Having the atmospheric lifespan of 114 years, nitrous oxide once
generated has the global warming potential of 298 for a 100 year time horizon15
.
IV. Chlorofluorocarbons (CFCs): These are synthetic compounds having industrial
origin and had huge usage as refrigerant coolants. At present their production and
release is highly regulated by international protocol and national legislations as it has
been scientifically proved that chlorofluorocarbons make significant contributions in
damaging the ozone layer of the atmosphere thereby leading to skin cancer.
V. Perfluorocarbons (PFCs): Aluminium and semiconductor chip manufacture has led
to the prominence of per fluorocarbons as a major greenhouse gas. Their atmospheric
lifespan is quite high and in the context of climate change, the major perfluorocarbons
include per fluoromethane and perfluoroethane. Soluble perfluorocarbons include the
oxygenated perfluorocarbons which are strongly present in the ocean environment.
Although the atmospheric concentration of perfluoromethane is around 100,000 times
lower than carbon dioxide, the radiative forcing of perfluoroethane is as much as one
five-hundredth of the radiative forcing16
due to carbon -dioxide. With the consensus
being generated about perfluorocarbons, the concentration of atmospheric

concentration; http://what-when-how.com/global-warming/perfluorocarbons-global-warming/
8
perfluorocarbons has reduced but the oxygenated perfluorocarbons has been found to
be present in the living tissues of humans, rodents and dolphins, etc. The oxygenated
perfluorocarbons have carcinogenic effects on human health and hence their emission
is necessary to be regulated.
VI. Hydrofluorocarbons (HFCs): While perfluorocarbons and sulphur hexafluoride
have atmospheric lifespan reaching to centuries, the atmospheric lifespan of
hydrofluorocarbons are several decades. However their ability to absorb infra-red
radiations is quite higher and it is such quality that makes it recognised as a major
greenhouse gas. As the hydrofluorocarbons do not contain ozone-destroying chlorine
or bromine atoms which deplete the ozone layer, their use as refrigerants and in air
conditioners continue to rise. Having the positive quality of protecting the ozone
layer, its use in recent times in the developing world has increased tremendously.
Projections reveal that by the year 2050, the use of hydrofluorocarbons will be 800
times more in the developing countries as that in the developed countries17
and the
said emissions are likely to warm the planet similar to 5-9 billion tonnes of carbon-
dioxide18
.
VII. Sulphur hexafluoride (SF6): According to the Intergovernmental Panel on Climate
Change, sulphur hexafluoride is a potent greenhouse gas whose global warming
potential is 23,900 times more than that of carbon-dioxide over a hundred year span
of time19
. Having excellent dielectric properties, sulphur hexafluoride is used for
insulation in electric power transmission equipments and in the semiconductor
manufacturing industries. It is also used as a tracer for gas leak detection. The sinks

available for sulphur hexafluoride are minimal and hence sources for its accumulation
include all man-made sources. Although sulphur hexafluoride is itself non-toxic, it
decomposes under electric stress and thereby produces toxic by-products20
.
Present records determine that globally there has occurred a steep increase in carbon dioxide
gas emissions from fossil fuels – approximately 21.39 billion metric tonnes (Gt) in 1990, the
benchmark year since when emission cuts began to be measured, to 22.97 billion metric
tonnes (Gt) in 1997, the year when the Kyoto Protocol was enacted to approximately 26.40
billion metric tonnes(Gt) every year during 2000-2005 and finally reaching 28.19 billion
metric tonnes (Gt) in 2005 (when the Kyoto Protocol was brought into force)21
. The question
that automatically crops in our mind after hearing all such quantitative amounts is that why
then has it taken so long for the environment to react to such high concentration of
greenhouse gases in the atmosphere. This is due to the fact that the oceans are much cooler
than the atmosphere and the thermal capacity of the water in the oceans is much higher than
the atmosphere. Further, the carbon dioxide stands dissolved in the oceans and such dissolved
carbon-dioxide does not have the ability to trap the sunlight and cause global warming. On
account of such features, it takes quite some time to warm and reveal itself through impacts.
Observing on emissions, it may be stated that most of the human induced emissions warm the
planet as they do not allow the long wave radiations to leave the earth and radiate back into
space. The exceptions to this list however include the aerosols such as organic carbon, soot,
sulphates, etc. and water vapour which in turn forms clouds that shower rains which cool the
planet by blocking the sunlight.
1.5 Causes Responsible for Global Warming:
20

http://www.rupe-india.org/mail.html
10
The cumulative onus for such stupendous and sharp increase in the emission of the
greenhouse gases is singly borne by humans alone for it is us, humans, who have contributed
towards the menace only to uphold our selfish wants and desires. Discussing on the major
ways in which humans have aggravated the issue it can be said that the major sources to be
blamed for such high increase in the greenhouse gas emissions include the power sector,
industry and the transport sector respectively. The contribution of the agricultural sector
towards the occurrence of global warming cannot also be ignored considering the fact that
agriculture contributes 14% to the problem22
, a percentage share similar to that made by the
transport sector. In most cases, the contribution of agriculture as a predominant source of
global warming stands very less highlighted on account of its prominent utility in feeding the
masses and tackling food insecurity and also generating livelihood options. Another
important source responsible for the emission of large concentration of greenhouse gases in
the atmosphere is the land use pattern change. It would be pertinent to mention in this context
that the change in the land usage has a contribution of 18% towards the enhancement of
greenhouse gases23
with peat fires, peat decay, deforestation and the burning and decay of
biomass occurring worldwide. In Brazil, for instance, between the years 1999 and 2005, there
has occurred continuous carbon dioxide emissions to the extent of 1.11 billion tonnes every
year only due to deforestation24
. The other instance that would be relevant to cite in this
context is the case of Indonesia where the total emissions per year for the same period was as
high as 2.27 billion tonnes on account of deforestation engineered deliberately to create land
space for the growth of biofuels25
.
Natural factors have continued to warm the planet even prior to the Industrial Revolution also
even prior to when humans had their presence felt on the Earth. The geological records reveal
22

http://www.rupe-india.org/mail.html 24
Ibid 25 Ibid
11
that such natural warming and cooling is a one thousand and five hundred years cycle which
began at least one million years ago. The last hundred years has noticed warming of the
planet and scientists are of the view that such warming is a recovery trend from the Little Ice
Age. There are several natural factors responsible for causing global warming, the most
prominent ones being, solar variability, continental drifts, changes in the Earth’s orbit,
volcanic eruptions, increase in the temperature of the oceans, plant and animal exhalation and
natural decomposition processes. Solar activity, for instance, is attended by increased solar
winds which shield the Earth from cosmic rays. As a consequence, the cosmic rays are not
able to play any meaningful role and help in cloud formation. Thus, when the sun’s activity is
stronger, there is a decrease in the formation of low-altitude clouds. Non-cloud formation
allows more sun’s rays to reach the Earth’s surface and thereby increase in the temperature
occurs.
It is human induced global warming that holds the real responsibility for the stupendous
increase in the concentrations of the greenhouse gases in the atmosphere. There are
multifarious factors accountable for the same, the most noteworthy being the burgeoning
overpopulation. Latest reports on world population mention that the current population of the
world is more than seven hundred billion26
with India housing more than 120 billion people27
.
Thomas L. Friedman in his book “Hot Flat and Crowded” has explained the present scenario
in a very lucid manner when he says:
“........It is getting hot, flat, and crowded. That is, global warming, the stunning rise of middle classes
all over the world, and rapid population growth have converged in a way that could make our planet
dangerously unstable. In particular, the convergence of hot, flat, and crowded is tightening energy

supplies, intensifying the extinction of plants and animals, deepening energy poverty, strengthening
petrodictatorship, and accelerating climate change.........”28
Resources have become limited to meet the requirement for such masses of population which
has in turn converted land use patterns to meet their social security needs. Migration of
people either in the name of urban prosperity or being forced upon to be displaced as a
consequence of developmental projects have both contributed to the change in land patterns.
Along with change of agricultural lands for urban settlements and industrial projects, forests
have been cleaned in major parts of the globe either to serve the requirement of timber or
non-timber forest produce or to engage the areas with more productive farming, namely bio-
fuel production. Sometimes however felling of trees has been continued indiscriminately
either with the connivance of forest officials or without them in the loop to meet other selfish
motives. As a consequence of over-felling of trees, the carbon sinks that are present in the
forests have shrunk thereby exposing us to further concentrations of carbon-dioxide. It can be
said that the unsustainable ecological resource management is one of the major factors that
induces global warming. The burning of fossil fuels to meet the demands of industrialization,
the emissions from the transport sector and the domestic sector continues unabated and hence
account for further global warming. The burning of coal and oil complemented with natural
gas has assisted mankind in the generation of wealth and prosperity but has also aided in their
destruction by enhancing climate change.
That global warming is here to stay is for sure but still the debate continues as to whether it is
naturally caused or human induced. Although the Human Development Report of 2007-2008
published by the United Nations Development Programme holds that there exists 90 percent
probability that global warming at the enhanced rate as it occurs in the present day is human
induced, there exist opponent views on the subject which hold that global warming is
28
http://www.huffingtonpost.com/2011/07/11/world-population-day-high_n_894592.html
13
continuing but it is not human induced. Such view opposes the findings of the
Intergovernmental Panel on Climate Change on the ground that most of the panellists of the
said Panel lack the required scientific qualifications. Also, the Intergovernmental Panel’s own
findings have been questioned by their own fraternity on grounds of questionable scientific
models being floated to proclaim global warming. The other submission made revolves
around the fact that, theoretically, the rate of global warming observed around the tropics
should be logically higher with the maximum being at six miles just above the Earth’s
surface. This, is however, not true in reality. According to the critics of human induced global
warming, balloon borne radiosondes reveal that there is rather a slight reduction in
temperature over the equator29
. Highlighting the said opposite stand, they firmly believe that
the natural causes of global warming have operated in the past and will continue to do so in
the future. Hence, the regulation of the carbon dioxide emissions is pointless. They further
highlight the positive outcomes of a warmer climate with more carbon dioxide and observe
that such climate is beneficial to a certain extent as it enhances agricultural productivity. It
has been observed that a slight increase in the concentration of carbon-dioxide in the
atmosphere would yield beneficial outcomes for countries such as Canada, Russia, Mongolia
and parts of northern Europe as their agricultural productivity will be enhanced.
Under the present backdrop, what remains prominently present is that global warming is
happening and is likely to continue in the near future at even higher rates if the present trends
of human induced global warming are not regulated. The Human Development Report of
2007-2008 further states that the greenhouse gas stocks are likely to increase by 4-5 parts per
million each year till the year 2035 if current trends of emissions continue. This means that
the accumulated stocks will increase to the extent of 550 parts per million which will in turn
29
Singer Fred S., “Global Warming: Man-Made or Natural?”, Imprimis, August 2007, Volume 36, No.8, available at http://www.hillsdale.edu/hctools/ImprimisTool/archives/2007_08_Imprimis.pdf
14
be anything close to 800 parts per million by the end of the 21st century. It therefore becomes
crystal clear that the sooner we are able to cut down such emissions, the lesser global
warming will occur and its impact on the future will also automatically stand reduced.
1.6 Impacts of Global Warming Enhances Global Warming:
It is not only the greenhouse gases that contribute towards global warming. Apart from the
emissions discussed hereinabove, the warming of the earth itself is also responsible for
generating effects that lead to further warming. As the ice-sheets melt, the melt water gets
formed. The melt water is darker than ice, and hence absorbs more heat thus resulting in
further warming. One of the foremost reasons for the speedy meltdown of the ice-sheets of
Greenland and Antarctica is due to such effect. Further, with the passage of time, the capacity
of oceans to absorb emissions reduces30
. The other impact of global warming which further
enhances global warming is the increase in global temperatures. With the rise in temperature,
metabolic processes get enhanced and allow the carbon dioxide in the soils to escape. This, in
turn, increases the concentration of carbon dioxide in the atmosphere which accelerates the
process of global warming.
Human aspirations and development patterns are responsible for global warming but when
the manifestations of global warming occur, the same is beyond human comprehension and
control. Hence in any discussion on global warming scenarios, two important points that
should be kept in mind are – firstly, it is immaterial where the emissions have occurred for
global warming impacts do not get determined and limited to geographical boundaries and
limitations and secondly, half of the emissions are supposed to be absorbed by oceans and
forests which act as carbon sinks. With the acceleration in the rate of global warming and the
rate at which deforestation continues, the number of such carbon sinks is sharply reducing as
30
Singer Fred S., “Global Warming:Man-Made or Natural?”, Imprimis, August 2007, Volume 36, No.8, available at http://www.hillsdale.edu/hctools/ImprimisTool/archives/2007_08_Imprimis.pdf
15
also the capacity of the oceans to absorb carbon dioxide is also getting reduced. Therefore an
effective and thorough assessment of the present global situation is necessary to be
undertaken for the sake of humans and for upholding the true spirit of humanity.
1.7 Objective of the Study:
The all encompassing existence of global warming is not subject to too many questions
today. What stands noticeable as a subject matter of question is the fact of unearthing the
existing direct visible impacts brought about by global warming and then matching them with
future projections on the issue. This is necessary to be commenced at the earliest to assess
the future of the planet. The subject of global warming has therefore to be gazed from climate
change that has happened or is likely to happen in the future.
There exist diverse direct and indirect methods to measure climate change. The direct
methods to measure climate change include the use of particular instruments to take regular
instrumental records of temperature, wind, sea-level and precipitation on a periodical basis
since the early nineteenth century while the indirect methods refer to measurements taken
using climatic indicators form paleoclimatic records such as from tree rings, the study of
corals, understanding ice cores and through borehole measurements. All such measurements
indicate that since 1750, the percentage increase in concentration of particular greenhouse
gases has been quite magnificent. While carbon dioxide concentration has increased 35%
more since the pre-industrial levels, the increase in methane and nitrous oxide concentration
has been around 153% and 18% higher31
.
All such evidences highlight that a comparative analysis of past and present visible changes
with the future projections is to be initiated on different parameters of the climate and the
diverse ecosystems to be certain on the growing dimensions of global warming. The objective
31
Peake Stephen and Smith Joe, “Climate Change: From Science to Sustainability”, Oxford University Press, Second Reprinted Edition 2010, Pg. 62
16
of the present study is to ascertain the findings of the present manifestations of climate
change impact and that of the future predictions to bring out the socio-political impact of
climate change on the entire world community and more especially upon India. Through such
study, the significance is to analyse and create a uniform framework of operation to deal with
global warming.
1.8 Issues and Problems:
Differences exist in the topography, geographical position, economical astuteness and
lifestyles of peoples of different countries and hence the limitations of countries exist
dependent on their capabilities and unique positioning. It is such differences that finally lead
to the emergence of issues in dealing with any global issue of concern. In attempting to assess
the impact of global warming, what is sought to be established is the fact that the issue of
global warming transpires as a modern environmental problem although we can trace its
existence since 1750 onwards. The modernism in global warming can be detected under two
counts – one, in the manner in which the impacts that are manifested can be addressed and
two, the modern independent touch inflicted by nations across the globe in dealing with such
contentious issue. The risks from extreme climate events are undoubtedly necessary to be
addressed through global concerted unified actions but the contentious issue of discussion is
the fact whether such concerted unified actions is possible to be undertaken in an
economically, politically and ideologically divided world.
1.9 Hypothesis of the Study:
The occurrence of global warming cannot be questioned in the twenty-first century.
Deliberations are regularly continuing between the developed, developing and the least
developed economies to find solutions to tackle global warming without hampering their
respective priorities and their respective capabilities. What can become the area of discourse
17
is the question whether it is possible to tackle the said socio-economic problem of global
warming in a unified manner which is globally acceptable. The present research study
attempts to discuss on the said issue and endeavours to arrive at prospective and positive
conclusions to deal with the contentious issue of global warming.
1.10 Research Methodology:
The title of the research work is a reflection of the very purpose the research study. This
research study is basically concerned with the analysis of the legal framework on global
warming both at the national and at the international levels. It attempts to showcase the
changes that have been proposed to be undertaken at the international and at the national
levels and the objective of proposing such changes in place of more prospective alternatives
with sustainable futures. The said study further attempts to highlight whether there is the need
for an alternative system of environmental governance to tackle the issue of global warming
at the international level and if so, what should be the legislative strength of such governing
authority.
The study of global warming is undertaken by analysing the diverse impacts of climate
change with the future projections to arrive at an understanding of the existence and the
expansiveness of the problem. In attempting to understand the same, literature review of
articles from books, journals, magazines, news reports and web references have been done
and the practical existence of the problem has been further grounded by analysing the diverse
legal documents on the issue. The assistance has also been taken from law journals, study of
international relations documents, case law references, periodicals and resolutions of the
United Nations. Furthermore, library research and books on contemporary environmental
issues and on globalization related and/or associated to the subject-matter have also been
used for the research study. In understanding the issues involved, secondary data has played

an integral role as most of the information obtained has been gathered from legal and non-
legal documents pertaining to global warming and climate change.
1.11 Limitations of the Study:
An-in-depth study has been undertaken to reveal the political clout that exists in the world
related to the issue of global warming. However in undertaking such study, proper
explanation of particular facts could not be provided due to lack of relevant information on
the said issue. For instance, relevant information on the quantified usage of water in the
developing economies prior to the initiation of developmental activities and post
development activities is not available and hence substantive understanding on the said issue
is not possible to be given.
1.12 Organization of the Study:
The entire thesis or research work has been segregated into seven chapters, including the
present introductory chapter and ‘Conclusions and Suggestions’. A brief outline of the plan of
study adopted is as follows:
1. Chapter 1: Introduction to Global Warming: Its Inducing Factors
This Chapter outlines the concept of global warming and introduces the relevance of
global warming with climate change.
2. Chapter 2: Facts on Global Warming
This Chapter observes the present impacts of climate change and highlights the future
projections of climate change.
3. Chapter 3: Legal Problems and Issues
19
This chapter focuses on the legal issues and problems associated with global warming
and thereby act as the foundation on which further discussion proceeds in the
forthcoming Chapters.
4. Chapter 4: International Legal Framework of Action to Resist Global Warming -
An Indepth Study
The existing international legal framework both within the aegis of the United Nations
and outside it established to deal with global warming is the subject-matter of discussion
in the present Chapter. It also analyses the said framework to highlight the loopholes
existing in such framework.
5. Chapter 5: National Legal Measures to Combat Global Warming – A Necessary
Initiative
The national legal framework to tackle the problem of global warming is evaluated in
the present Chapter. Emphasis has been laid to highlight the legal scenario from the
stage of planning to the stage of implementation followed by interpretations of the said
laws made by the Judiciary in this regard. An analysis of the entire legal framework of
India brings out an interesting shade in the study of environmental law and more
especially in the study on global warming.
VI. Chapter 6: Public Involvement in Combating Global Warming
Enactment of laws merely cannot help in tackling the contentious issue of global
warming. The present Chapter emphasize on the role of public participation in helping to
combat climate change and discusses the different mechanisms that are operative to
establish public participation in the domain of global warming.

VII. Chapter 7: Conclusions and Suggestions
The concluding remarks based on the present research work is depicted in the present
Chapter along with suggestions to adapt and mitigate the said issues that would help in
arriving at the solutions to the issues involved, conscientiously.
