Global Warming


  

1.INTRODUCTION :-

● From The Stone Age to the modern era man has come a long 
way. In his pursuit of comforts of life he ignored the threat of 
pollution andenvironmental degradation caused by 
industrialization.

● Global warming is not new as this process occurs naturally and 
keeps the Earth’s temperature about 50 degrees. Fahrenheit 
warmer than it would be otherwise. Without this natural cover, 
Earth’s surface would be colder than it is today,, making the 
planet freezing and devoid off life.


  

What is GREENHOUSE EFFECT

● Gas in the atmosphere, such a water, carbon dioxide, 
methane, CFCs and nitrous oxide, absorb infrared light 
andwould otherwise escape to space, radiating it back 
towards the planet’s surface.

● These gases are called ‘ greenhouse gases’ and they have 
acritical 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”.


  

Effect on Global Warming 
i.  Serve Changes in Weather :

● 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.


  

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.


  

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 
emissionof 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 .


  

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.


  

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. 
Islandsin danger of being submerged, from the 
Pacific to the Caribbean are panicky. The lives 
of million people will be affected by these.


  

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 LIKETHE SAME IN 
DESERT REGION OR MORE THAN THAT


  

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.
