here you will get each and every thing you need in global enviromental issue . they are enviromental problems. they are futher divide in sub parts global warming, acid rain,ozone layer depletion etc.. you would get some thing which will help you to make your ppt more interesting.

3. 1. Global warming
2. Acid rain
3. Ozone layer
4. depletion
5. Biodiversity loss
6. Infectious disease

4. refers to an increase in average global
temperature, also called:
1. Climate Change
2. Greenhouse Effect

5. Infrared
radiation
 Some passes
through the
atmosphere
 Some is
absorbed and
re-emitted in
all directions
by
greenhouse
gas modules
Solar radiation
 some is
reflected by
the earth
and the
atmosphere
 some
passes
through the
atmosphere
and is
absorbed by
the earth,
warming it

6. Gases Source
carbon dioxide (CO2) fossil-fuel burning, de-forestation
methane (CH4)
agriculture activity, decomposition and disposal of
waste
nitrous oxide (N2O)
emitted during agricultural and industrial activities, and
during combustion of solid waste and fossil fuels
hydrofluorocarbons
(HFCs) industrial activities
perfluorocarbons
(PFCs) industrial activities
sulphur hexafluoride
(SF6) industrial activities

8. 1) Atmospheric life time.
2) Global warming potential.
3) Atmospheric concentration.

9. 1) Concentration vs. Emissions.
2) Forecasts about emissions are very sensitive.

10. 1) Longer growing seasons
2) Poleward and altitude shifts of
plants and animal ranges
3) Decline of some plant and animal
population ( Drive 15 - 37% of
living species toward extinction by
the middle of the century)
4 ) Early tree flowering, emergence
of insects and birds eggs laying
5) Damage to natural systems
Many of these impacts are
irreversible

11. 1) Shrinking glaciers & thawing
permafrost.
2) Later freezing and earlier
break up of river and lake ice.
3) Sea level rise.
4) Higher incidence of floods and
droughts in some regions.

12. Systems at risk include:
 water resources
 Agriculture and forestry
 Coastal zones and marine
systems
 Decreasing water
availability in regions where
water is already scarce
 Human health and risk of
disease

13. 1) Carbon dioxide targets.
2) Carbon dioxide emissions.
3) GHG control (quantitative incentives rather
than price incentives).

14. 1) Plans for controlling emissions.
2) No commitments on:
A particular emissions reduction.
A timetable for any such reduction.

15. 1) Conditions to be in force.
2) Industrialized nations.
3) Developing countries.

16. 1) Emissions Trading or “HOT AIR TRADING”
2) Joint Implementation (JI)
3) Clean Development Mechanism (CDM)

17. 1) Increase the capacity of ‘pools’ that absorb
carbon dioxide and other GHG from the
atmosphere.
2) Decrease the rate of emissions of GHG
(reducing GHG inflows).

18. 1) stop using burning fuels and changes in fuel
mix (from fossil to renewable energy)
2) use the new technologies that are now
available, like better filters.

19. 1 ) Stabilizing population growth worldwide.
2) power stations should not be permitted to
discharge warm cooling waters into rivers
and oceans.

20.  Financial and technological transfers from
developed to developing nations.
 helping low-income nations develop cleanly.

21.  learn and use good ideas and solutions
from other countries that help us eliminate
global warming. For example, a country that
is fighting global warming and producing less
polluting fuels is Brazil. Instead of gasoline
Brazilians use alcohol, which is made from
sugar cane and cassava. The exhaust fumes
from this alcohol fuel are almost clean
enough to breathe.
