This document discusses the impact of global warming. It begins with an introduction that defines global warming and explains why it is important to understand. The main body then describes the effects of global warming on nature, including increasing storm strength, rising sea levels, and species habitat changes. It also discusses the economic impacts, such as increased agriculture costs, flood defense challenges, migration pressures, and transportation and development impacts. The conclusion emphasizes that countries, scientists, and people need to take action to address this problem.

1. The impact of Global Warming

2. Presentation structure
1. Intro
• Definition.
• Why it is important to know about it?
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
• Effect of global warming on the economy :
 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?

6. Effect of global warming on
Nature

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.

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.

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.

12. Effect of global warming on the
economy

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.
