1. Intro
• Definition.

2. Main body:
• Effect of global warming on nature:
1. On weather.
2. On the water system (ocean, lakes, sea).
3. On the Ecosystem.
3. …Continues

agriculture.
Flood defense.
Migration.
Transports.
Development.
3. Conclusion.
4. Definition& the impotence to know
about it
• Do you know the meaning of global
warming?
• Why do you think it is important to know
about it?
7. On weather
Storm strength is increasing.
Wind speed is increasing
.
Hurricanes will increase.
Arctic region experienced a temperature rise 1
to 2,5 C in last 50 years.
8.
9. On the water system
((ocean, lakes, sea
• The sea level will increase.
From 3000 years ago to the start 19 th
century sea level was constant.
When the sea level increase, the cities on
the coasts will be in a risk to be vanished.
Many lakes will disappear as well as many
will be created for permafrost melting.
10.
11. .On the Ecosystem
Ecosystem means: An ecological community
together with its environment, functioning as a
unit.
Some species are being forced out of their
habitats.
Polar bear.
Emperor penguins.
Some species are flourishing.
Changing of species behaviors.
13. .Agriculture
• Global warming increase the temperature
which increase the demand of water.
• Lead to:
Expensive prices for the crops.
Expensive prices for the farmlands.
Expensive prices for the water.
Some farmlands will not produce the
same crops they used to produce.
14. Flood defense
• Many of the world’s largest trade cities is
in the coast which will be effected from the
rise of sea level.
• The low-lying countries such as
Bangladesh and Netherlands would be
worst hit by any sea level rise.
15. Migration
• Some Pacific island nation such as Tuvalu
will have a possibility of an eventual
evacuation.
16. Transportation
• Road.
• Airports runways.
• Railway line.
• Pipeline (including oil pipeline, sewers, water
main)
It may require maintenance and renewal as they
become a subject to a greater temperature
variation.
17. Development
• Global warming may slow economic
development and poverty reduction.
• Global warming will increase hunger and
disease in Africa
18. QUOTES ON GLOBAL
WARMING
“Global warming is too serious for the world any longer to
ignore its danger or split into opposing factions on it”
TONY BLAIR
“People tend to focus on the here and now. The problem
is that, once global warming is something that most
people can feel in the course of their daily lives, it will be
too late to prevent much larger, potentially catastrophic
changes”
ELIZABETH KOLBERT
19. Conclusion
Countries should take the effects under
consideration.
Scientists should find a solution for this
problem for the next generation.
People should take an action for this
problem.
Wind speed had risen from 20% in 1970s to 35% in 1990s Hurricanes increased in the US by 7% since 1970.
The sea level will increase because of ice melting. For example the Greenland and the Antarctic ice sheet. An increase of 1.5 to 4.5 is estimated to lead to an increase of 15 to 95 cm. From 3000 years ago to the start 19 th century sea level was constant, rising at 0.1 to 0.2 mm/yr; since 1900 the level has risen at 1-2 mm/yr.. Lakes: example Siberia’s lost around 11% of 11,000 lake since 1971.whereas in western Siberia is at the stage where melting permafrost is creating new lakes.
Some species are being forced out of their habitats. possibly to extinction because of the changing condition. Species that rely on cold weather condition will be hit hard. Changing of species behaviors: example, now a days frogs breeding, flower blossoming and birds migrating an 2,3 days earlier each decade as well as grass has become established in Antarctica for the first time.
Some Pacific island nation such as Tuvalu will have a possibility of an eventual evacuation: as the flood defense may become economically inviable for them. Tuvalu already has an agreement with New Zealand to allow phased relocation.
Global warming may slow economic development and poverty reduction: and make it harder to achieve the Millennium development goals. Global warming will increase hunger and disease in Africa: due to the decrease of the rainfall and sever weather events that will happen.
