is the increase of the Earth’s average surface temperature due to a build-up of greenhouse gases in the atmosphere.
is a broader term that refers to long-term changes in climate, including average temperature and precipitation.
Increase in the average measured temperature of the Earth's surface air and oceans
How Global Warming Works Greenhouse gases Fossil fuels (coal, oil, natural gas) Carbon Dioxide (CO 2 )
CAUSES OF GLOBAL WARMING
Pollution from coal, natural gas, and oil
CO 2 from airplanes & vehicles
Increased CO 2 results in
The Sun’s energy passes through the car’s windshield. This energy (heat) is trapped inside the car and cannot pass back through the windshield, causing the inside of the car to warm up. Example of the Greenhouse Effect
Global warming causes
Melting of glaciers
Polar Bear Extinction
Warmer waters and more hurricanes
Increased probability and intensity of droughts and heat waves
Melting Polar ice caps
WHERE IS my habitat…!!!
ANTARCTICA – losing ice faster..!!!!!! BEFORE NOW
Major CONSEQUENCE of global warming is…………. GUESS WHAT !!
At some places, it
SOMEWHERE it’s tooo…….ooo
WHEREAS At others tooo…..
Its all because of
CAUSED BY WHOM…?????
WHO Is THE CULPRIT??????
WE are the ones causing It
WE need PROOF
SO Here’s the PROOF

When did global warming start?
Global Atmospheric Concentration of CO 2
It’s NOT too LATE ACT NOW!!!!
We can stop global warming!
JUST DO…………these Follow the arrow…..
Turn off your computer or the TV when you’re not using it.
Turn off the lights when you leave a room.
Be Bulb Smart—Use CFLs Incandescent Compact Fluorescent
1,430 lbs. CO 2 pollution avoided
500 lbs. of coal
Dress lightly when it’s hot instead of turning up the air conditioning.
Unplug unused electronics
Drive LESS, drive SMART Use a bicycle or bus
Have Faith on……………
Fuel efficient cars
Hey…..!!! Its working
Global Warming: Shifting Gears
2007 Goal: Reductions in CO 2 Per Year Billions of Metric Tons Carbon
