IT IS A PPT ON GLOBAL WARMING....ITS EFFECTS ON THE EARTH AND WAYS TO STOP IT...

1. GLOBAL
WARMING

2. WHAT IS GLOBAL WARMING
GLOBAL WARMING - Global Warming is
the increase of Earth's average surface
temperature due to effect of greenhouse
gases, such as carbon dioxide emissions from
burning fossil fuels or from deforestation,
which trap heat that would otherwise escape
from Earth is called global warming.

3. DISADVANTAGES OF GLOBAL WARMING
1. Ocean circulation disrupted,
disrupting and having unknown effects
on world climate.
2 . Higher sea level leading to flooding
of low-lying lands and deaths and
disease from flood and evacuation.
3 . Deserts get drier leaving to
increased desertification.

4. 4. Changes to agricultural production
that can lead to food shortages.
5. Water shortages in already water-
scarce areas.
6 . Starvation, malnutrition, and
increased deaths due to food and crop
shortages.
7 . More extreme weather and an
increased frequency of severe
and catastrophic storms.

5. 8 . Increased disease in humans and
animals.
9 . Increased deaths from heat waves.
10 . Extinction of additional species of
animals and plants.
11 . Loss of animal and plant habitats.
12 . Increased emigration of those from
poorer or low-lying countries to wealthier or
higher countries seeking better (or non-
deadly) conditions.

6. 13. Additional use of energy resources for
cooling needs.
14. Increased air pollution.
15. Increased allergy and asthma rates due
to earlier blooming of plants.
16. Melt of permafrost leads to destruction of
structures, landslides, and avalanches.
17. Permanent loss of glaciers and ice sheets.
18. Cultural or heritage sites destroyed faster
due to increased extremes.
19. Increased acidity of rainfall.

7. 20. Earlier drying of forests leading to
increased forest fires in size and intensity.
21. Increased cost of insurance as insurers
pay out more claims resulting from
increasingly large disasters.
22. Aggressiveness will increase, leading to
an increase in the murder rate.

8. ADVANTAGES OF GLOBAL WARMING
1. Arctic, Antarctic, Siberia, and other frozen
regions of earth may experience more plant
growth and milder climates.
2 .The next ice age may be prevented from
occurring.
3 .Northwest Passage through Canada's
formerly-icy north opens up to sea
transportation.

9. 4. Less need for energy consumption to warm
cold places.
5. Fewer deaths or injuries due to cold
weather.
6. Longer growing seasons could mean
increased agricultural production in some
local areas.
7. Mountains increase in height due to melting
glaciers, becoming higher as they rebound
against the missing weight of the ice.
8. Boundary disputes between countries over
low-lying islands will disappear.
