THIS MAY BE THE FUTURE OF OUR PLANET EARTH….

Sky scrapers, subways, in fact the whole city.. One day will be under water..Because of rising Sea levels due to thermal expansion of the ocean..

Our existence…Records…Submerged……

Destroyed…

Melting ice,, could be one of the reasons leading destruction…

The arctic ice cap is all gone…

Increased water temperature: As global warming is associated with the rise in average temperature of the

planet this increased temperature passes on the heat to water sources present on earth. This increased water temperature is a reason to worry because they are responsible in killing Flora and Fauna available in these sources. Already due to this reasons we

have lost some of the rarest and oldest algae species present deep below the sea

Increased climatic disasters: global warming problems are a major threat to our planet as they have increased the frequency of natural

disaster. Many of the disasters caused in recent years like tornadoes, hurricanes, floods and droughts are some of the best problems of

super imposed threats.

Floods and weather disasters

Riots!!!!!!!!!!

• Bad weathers..• Record floods…• Record heat• Record Drought• Record natural and man made disasters…

• ExtintionThis i

s not w

orld u want to

get in to

…..

But is th

is our d

estiny???

We should be so

lving this p

roblem right n

ow…

but before going on so

lution lets descu

ss on

what is global w

arming

and

What is th

e main re

ason behind it ..!!

• We are happy today but it might be the world we my not know tomorrow..• Global warming..• The things we need to know..

For 2.5 million yearsthe earth’s climate is fluctuated

cycling to ice ages to warm experiencebut in the last century the earth’s

temperature is rising unusually fast..About 1.2 to 1.4 degree

fahrenheit..Scientist belive that its human activity..

That Is rising the temp. up..A Process known as global warminng

Eversince the industrial revolution began..

FACTORIES, POWER PLANTS AND EVEN CARS AND FOSSIL FUELS

SUCH AS OIL AND COAL.. RELEASING THE HUGE AMMOUNT

OF CARBON DIOXIDE AND ANOTHER GASES IN THE

ATMOSPHEHERE..

THESE GREEN HOUSE GASES TRAP HEAT NEAR THE EARTH..

THROUGH A NATRUALLY OCCURING PROCESS..

CALLED THE GREEN HOUSE EFFECT..THE GREEN HOUSE EFFECT BEGINS WITH THE SUN AND THE EANERY ITS RADIATES

THE EARTH AD THE ATMOSPHERE ABSORBS SOME OF THIS ENERGY..

FOR THE REST IS RADIATED BACK IN TO THE SPACE..

NATRUALLY OCCURING GASES IN THE ATMOSPHERE TRAPS..

SOME OF THESE ENERGY AND REFELCTS BACK WARMING THE

EARTH..

SCIENTISTS NOW BELIVE THAT..THE GREEN HOUSE EFFECT IS BEEN

INTENSIFIED..BY THE EXTRA GREEN HOUSE

GASES..THAT HUMANS HAVE RELEASED..

EVIDENCE FOR GLOBAL WARMING INCLUDES..

THE RECENT STRING OF VERY WARM YEARS..

SCIENTISTS REPORT THAT THE YEAR 1998.. WAS THE WARMEST

YEAR MEASURED IN THE HISTORY..2005 COMES THE 2ND..

THE GREEN HOSE GASES CARBON AND METHANE..

HAVE HITTED THERE HIGHEST LEVEL IN 20,400 YEARS..

ARCTIC SEA ICE IS ALSO MELTING..IT HAS DECRESED 10 % IN THE LAST

30 YRS.

AS LONG AS INDUSTRIALISED NATIONS CONSUME ENERGY..

• AND INCRESE THERE FOSSIL FEUL CONSUMPSION.. THE CONCENTRATION OF GREEN HOUSE GASESIN THE ATMOSPHERE WILL CONTINUE TO RISE..

• ALL THE MUCH REMAINED ABOUT LEARNING GLOBAL WARMING IS THAT MANY ORGANISATIONS.. WORK FOR CUTTING THE..

• GREEN HOUSE PRODUCING MACHINES… • TO CONTROL THE EFFECTS OF GLOBAL

WARMING..

• CONSUMERS CAN HELP BY SAVING ENERGY ARROUND THE HOUSE..

• SWITCHING TO COMPACT LIGHT BULBS..• AND DRIVING FEW MILES IN D CARS

AND USING ECO FRIENDLY VEHICALS LIKE CYCLES..

• THESE SIMPLE CHANGES WOULD HELP TO KEEP THE YEAR COOLER..

THE END..

WE HAVE ONLY ONE HOME..
