An appeal to our Friends..

The issue of climate change needs to be given a seriousthought, and our Mother Earth would like you all to be

responsible citizens and contribute your part in doing

good to the environment

Introduction to IPCC

Intergovernmental Panel On Climate Change

Established in 1988

Its mission is to provide comprehensive scientific assessments of

current scientific, technical and socio-economic information

worldwide about the risk of climate change caused by human

activity.

It does not carry out its own original research nor does it do the

work of monitoring climate or related phenomena itself.

Introduction to IPCC

The Main activity of IPCC is to publish special reports on topics

relevant to Implementation of UNFCCC

UNFCC- United Nations Framework Convention on Climate

Change is an international treaty acknowledging the

possibility of harmful climate change.


6/18

Introduction to AR4

By IPCC

It provides a great deal of new scientific knowledge which

carries learning with the special value in a world where climate

change has now come to occupy centre-stage of contemporary

global issues.


7/18

Limitations

Needs public awareness and public demand for the

governments to take notice of what the public demands

It can happen only if the manifestation is widespread and strong

But, the ability and capacity Of IPCC to spread the findings is

limited.

Introduction to TERI

The first big footThe conference on Global warming and climate change:

Perspectives from developing countries, New Delhi, 1989

The agenda was to concentrate on equity, efficiency and burden sharing

needed to be evaluated in defining the role of developing countries

After conference , TERI established a Centre for Global Environmental

Research

This centre did the following task

Conducted the research

Dissemination of results through message to public, school children,

advising govts. and multilateral organizations on regular basis.

Dangerous Anthropogenic

Interferences

Ever since the industrial age, there has been a clear trend of rising

temperatures.

A drastic increase in GHGs due to anthropogenic interference.

Human factors have overtaken the natural factors in the second half of the

20th century.

A 17cm increase in sea level in just the past decade.

70% increase in GHGs since 1970 to 2004 This highlights the ineffective nature of global action even though the UNFCC

was established in 1992 and the KP in 2005

Future Projections

IPCC has carried out projections of the future changes in temperature as well

as their effects to our earth and us.

The projected increase in temperature by the end of 21stcentury will be

within the range of 1.1-6.4 Degree Celsius.

Even with best efforts by us it will still increase by 2.5 Degree Celsius taking

into account the average of 0.74 Degree Celsius increase in the 20th Century.

There are some very crucial effects of this future projections and increase in

the climate.

Major Concerns around the Globe

Mega Deltas extremely susceptible to major coastal flooding.

75-250 million people living under water stress in Africa by 2020.

Decline in agricultural yields by almost 50 % by 2020 in some parts of

Africa.

Arctic region is warming twice as fast than the rest of the globe.

Global Ice meltdown could leave more than 700 million as environmental

refugees.

Adaptation to the impacts of climate change must be taken seriously, also

there is a sense of urgency to take measures so as to bring about

stabilization of the earths climate.


15/18

Major Concerns around the Globe

In order to stabilize the temp. increase between 2-2.4 Deg. C. the extent of

mitigation required would impose a cost of no more than 3% of the GGDP

in 2030.

The co-benefits from such efforts include higher energy security, lower

levels of air pollution, commensurate health benefits, higher levels of

employment etc.

The world would incur a negative costs related to such a path of

mitigation.

Very little time to embark on the preferred trajectory of mitigation.
