LADUKISHORE SAHOO
Regd. No.: IPCC/ERO-0162965

2. What is Global
Warming?
*An increase in the
average temperature
of the Earth
*Recent debate, but
has been looked at by
scientists for centuries

3. What causes it?
* CO2
* Methane
* Nitrous oxide
* Fluorinated
compounds
Greenhouse Gases:
Human Impacts-

4. What causes it?
 Natural Impacts:
*Volcanoes
*Water vapor
*clouds
*Change in sun’s
energy output

5. Who’s Responsible?
 Burning of fossil
fuels is main cause
•U.S. is leader in
greenhouse gasses
•Human impacts are
changing the
composition of the
atmosphere

6. What are Causes of
Global Warming?
What is air pollution?
-The presence in the air of substances
which pose a potential threat to human
health and/or the environment.
-The presence of particles in the air
which decrease visibility
-The U.S. EPA estimates that 50 percent
of the U.S. population is exposed to air
pollutants exceeding current federal
standards.

7. Energy production from
fossil fuels
-Carbon dioxide, sulfur
oxides, particulates
-Increase in
greenhouse gases,
acidic precipitation
Air Pollution

8. Automobiles, other
transportation
sources
-Carbon dioxide,
nitrogen and sulfur
oxides, products of
incomplete combustion
-Increase in
greenhouse gases,
acidic precipitation
Air Pollution

9. Refrigeration devices
including home,
commercial, and
vehicles
-Chlorofluorocarbons
-Destruction of the
stratospheric ozone
layer
Air Pollution

11. The Carbon Cycle

12. Effects of Air Pollution and
Global Warming
-Rising Sea Level
-Change of precipitation and local climate
conditions; acid rain
-Alteration of forests and crop yields
-Expansions of deserts into existing
rangelands
-More intense rainstorms
-Not all long-term effects can be determined

13. What Is Being Done:
Alternatives
Renewable Energy Sources
Solar Energies
Wind Power
Biomass
Geothermal

14. Changes In Vehicle
Systems
Hybrid
Fuel Cell
Battery-
Electric

15. Conclusion
 Responsibility to improve
environmental conditions lies upon all
of us as individuals
 Concentrate on preventing
environmental degradation before it
starts
 Alternatives are feasible and Can be
Used
