Global warming is caused by an increase in greenhouse gases like carbon dioxide that trap heat in the atmosphere. This greenhouse effect has raised Earth's average surface temperature and caused changes to the climate. Effects of global warming include more severe weather, melting Arctic ice and permafrost, rising sea levels that threaten coastal and island areas, and disruptions to ecosystems that support Arctic communities. The Kyoto Protocol was an agreement signed in 1997 where developed nations committed to reducing greenhouse gas emissions by an average of 5% below 1990 levels by 2008-2012, but global temperatures continue rising without sufficient action. Failure to curb emissions risks major climate change and destructive future warming.

1. GLOBAL WARMING

2. WHAT IS GLOBAL WARMING?
lobal Warming is the increase of Earth's
average surface temperature due to effect of
greenhouse gases, such as carbon dioxide
emissions from burning fossil fuels or from
deforestation, which trap heat that would
otherwise escape from Earth. This is a type of
greenhouse effect.

3. 2.What is GREENHOUSE EFFECT
?
 Gas in the atmosphere, such a water, carbon dioxide,
methane, CFCs and nitrous oxide, absorb infrared light and
would otherwise escape to space, radiating it back towards
the planet’s surface.
 These gases are called ‘ greenhouse gases’ and they have a
critical role in determining the temperature of the Earth’s
surface and the living conditions on the planet.
 This natural process is called the “greenhouse effect”.

4. 3.Effect on Global Warming ?
Earth’s surface to a new high of 14.57 degree centigrade.
 Rise in temperature was marked by unusually severe weather in
many parts of the world.
 The irony of this global warming is that while it could reduce
climatic changes by drying up rains.
 It could also raise sea levels with disastrous consequences for
islands and low- level coastal areas.
i. Serve Changes in Weather :

5. II.Impact on Arctic Ecosystem :-
 The ecosystem which sustains the livelihood of Arctic
residents is melting the ice as temperature rise.
The layer of permafrost is melting, causing an inland lake to
drain into the ocean and killing fresh water fish.

6. KYOTO
PROTOCOL

7. iii.Kyoto Protocol :-
 A un- brokered treaty was signed by in 1997 in Kyoto Japan.
It was called the Kyoto Protocol.
 It commits the rich countries to binding cut in their emission
of greenhouse gases, such as carbon dioxide.
 The developed countries agreed to cut their emissions by a
collective average of 5 percent below their levels in 1990 by
2008-2012.
 Representative Climate Conference (COPC) in Nov 2000,
and discussed about the implementation of the Kyoto Protocol.

8. iv. Erratic Rain :-
 People around the world will experience climate
changes and the erratic rainfall China to Africa will
jeopardize the lives of many people.
 IT is now nearly a decade since the IPCC accepted
that human activates were changing the world’s climate.
 The most severe warming is seen in the Arctic were
the ice pack is shrinking, and thinning, according to the
US experts.

9. v.More storms, foods, droughts,
submergence of islands :-
 Scientists have warned that a warmer world
will mean more storms, floods, droughts, and
snowfalls.
 The countries that have to suffer most if the
Hague talks fail are the small countries. Islands
in danger of being submerged, from the Pacific
to the Caribbean are panicky. The lives of

10. vi. Ozone Getting Depleted :-
 Pollution from transport is the fastest growing source of
carbon dioxide emissions since the industrial revolutions
 Carbon emission levels responsible for 70 percent of global
warming vary widely among nations.
 Due to these emissions the ozone layer that provides a
protective shield over the Earth from the harmful ultravoilent
radiation is getting depleted.
 Another greenhouse gas, methane, has more than doubled.
RESULT OF THIS, VERY HOT WEATHER LIKE
THE SAME IN DESERT REGION OR MORE THAN

11. vii.Major Climate Change :-
 If we do not act to reduce the emission of these heat-
trapping gases, it is predicted that global temperature could
rise 2 degree to 6degree Fahrenheit in the next 100 yrs. Just
a few degree difference in the global average temperature
can mean a major climate change.
 The amt o greenhouse gases that are released could be
controlled through prudent planning and implementation of
environmental priorities. Man has to act now to insure
against the risk of destructive future warming by reducing
the greenhouse gas emissions.
