4. Introduction
Climate Change:
Climate change is a change in the statistical distribution
of weather patterns when that change lasts for an
extended period of time.

5. Reasons:
• Solar Rays:
1. Ultraviolet rays as well as other
harmful rays
• Energy Production:
1. If the nation's climate warms by 1.8°F, the demand for energy
used for cooling would increase by about 5-20%.
2. Changes in energy demand will likely affect greenhouse gas
emissions
• Industrialization
1. Made our lives easier
2. emits very large amount of carbons, Nitrous Oxide as well as
Sulphur

6. Reasons:
• Carbon Emission:
1. Carbon emission a man made and is
one of the main reasons for climate change
2. The top four carbon
emitters are
China, USA, Russia and
India releasing 8715.31,
5490.63, 1788.14,and
1725.76 Million Metric
Tons per year.
Deforestation:
In 2005 was estimated to
be around 30% of the planet’s land
area

7. Reasons:
• Carbon dioxide is rising
very at a very alarming
Rate
• Carbon dioxide destroys
ozonosphere

8. Reasons:
• Fossil Fuels:
Increased the amount of carbon in the atmosphere in 2005 to 2014
decade the amount of
carbon in atmosphere has increased to 21.06 ppm (parts per million).
• Vehicles:
1. Emits 10% of the carbon
2. Can’t be avoided
• Nonveg foods:
15% of the carbon is caused because of transportations, refrigeration
and feeding for Cattles and other meat products.

9. Effects of Climate change
I. Effects on nature:
1. Higher Temperature
2. Storms
3. Low rain at some places
4. Deserting

10. Effects of Climate change
II. Effects on Ecology:
1. Extinction of many animals
2. Sinking of costal area
3. Diseases
4. Decrement of pure water supply
5. Migrating to northern area

11. Effects of Climate change
III. Effects on Economy:
1. Lost productivity
2. Damage to property and infrastructure
3. Species will change
4. Poor gets poorer

12. Effects of Climate change
IV. Effect on Geography:
1. Cities will sink
2. Lives threatened
3. Sudden water problems

13. Prevention
• LIMIT GLOBAL WARMING POLLUTION
Raise Consciousness
• GREEN JOBS AND CLEAN ENERGY
1. Choose renewable energy
2. Using Biogas
3. Planting trees

14. Scientific Discoveries to fight Climate
Change
1. Hydrogen Cars
2. Nuclear Power plants
3. LED lights
4. Artificial Trees
5. Using Sulfate
6. Using Valleys
7. IPCC summits
8. Geo Engineering

15. Conclusion
•Lets rise our voice against climate
change.
•Time for true leadership is now.
•Our world is facing a dramatic
change
•Lets all of us live in a harmony
without a constant thread of nature

16. Slogan
“Lets make the Earth Lovely once more”
