El Nino
• expected arrival of the one of the biggest
El Nino weather patterns in the second
half of the year.
• Expected Southeast Asia,
• 20,000 dead and US$97 billion in
damages (1997 and 1998).
• Increased temperature and rainfall will hit
Southeast Asia.
5. Global Warming?
• Global warming is when
the earth heats up (the
temperature rises)
• The changes in the
surface air temperature,
referred to as global
temperature, brought
about by the enhanced
green house effect, which
is induced by emissions
of green house gases in
the air.

8. THE CAUSES OF
GLOBAL WARMING
Greenhouse gasses
• In earth’s atmosphere collect heat and light from the sun.
• Water vapor, carbon dioxide, methane, nitrous oxide,
and ozone.
• Too many greenhouse gasses in the air, will trap too much
heat earth will get too hot.
• people, animals, and plants would die

9. Greenhouse Effect
•when the temperature rises because the sun’s heat and
light is trapped in the earth’s atmosphere.
•Example: Heat is trapped in a car.
•This is because the heat and light from the sun can get
into the car.
•The heat and light can get through the atmosphere, but it
can’t get out. Then, temperature rises.

10. Human action:
• The combustion of fossil fuels (coal, oil and natural gas)
From vehicles, factories and power plants for electricity.
• Deforestation and Land
Plants use CO2 to produce food (photosynthesis).
Forest clearing activities and the area of land increased greenhouse
gases.
Less plants use CO2 to process photosynthesis.
Without the control of the authorities it will worsening the current
situation.

Significant changes to the amount and
pattern of precipitation
Modifications of trade routes

Kyoto Protocol
• The Kyoto Protocol is an agreement under
which industrialized countries will reduce their
collective emissions of greenhouse gases by 5.2%
compared to the year 1990.
The developed countries
agreed to cut their emissions
by a collective average of 5
percent below their levels in
1990 by 2008-2012.

of global warming that is
a. Limiting release of carbon dioxide
– Replacing fossil fuel with energy source.
– Using fossil fuels more efficiently.

16. What You Can Do To Reduce
Global Warming
Page 16
• Reduce, Reuse, Recycle
• Use Less Heat and Air Conditioning
• Change a Light Bulb
• Drive Less and Drive Smart
• Buy Energy-Efficient Products
• Use the "Off" Switch
• Plant a Tree
• Encourage Others to Conserve
El Nino is the change in sea surface temperature uncertainty. In the middle of the Pacific Ocean will overheat causing high liquefaction . There will be a violent wind two different preparations
El Nino, an abnormal warming of surface ocean waters in the eastern tropical Pacific, is one part of what's called the Southern Oscillation.
.
The rise of average temperature of earth’s atmosphere and the oceans.
Traps more heat in atmosphere
Increase in global temperature
It happens when greenhouse gases (carbon dioxide, water vapor, nitrous oxide, and methane) trap heat and light from the sun in the earth’s atmosphere, which increases the temperature.
This hurts many people, animals, and plants. Many cannot take the change, so they die.
The primary greenhouse gases in the Earth's atmosphere are
With too many greenhouse gasses in the air, the earth’s atmosphere will trap too much heat and the earth will get too hot.
Perjanjian Kyoto yang ditandatangani di Kyoto, Jepun pada 1997 perlu dilaksanakan dengan lebih serius, cekap dan berkesan.
Lebih dari 160 negara yang terlibat dengan draf perjanjian tersebut yang menekankan kepada pengurangan pembebasan gas rumah hijau.
Daripada jumlah itu, 38 buah negara industri perlu menghadkan pengeluaran CO2 dan gas rumah hijau yang lain.
