Title: Climate Change What does it mean to You?


1
Climate ChangeWhat does it mean to You?
2
Have you heard about the golden age when there
were no typhoons, great earthquakes and volcanic
eruptions in the Philippines?
3
Have you heard what shall happen in the future in
the Philippines?More and greater typhoons, sea
level raising about 1 2 meters and hot climate.
WE shall examine these topics today!
4
Typhoons
Both Tropical Storm Fengshen and Tropical Storm
Fung-Wong can be seen nearing China in this rare
true color image taken on July 26, 2002, by the
Moderate Resolution Imaging Spectroradiometer
(MODIS), flying aboard NASA?s Terra spacecraft.

5
How the Philippines is affected
Tracks of all tropical cyclones in the north west
Pacific Ocean between 1980 and 2005. The vertical
line to the right is the International Date Line.

Philippines only
From a scientific article Interdecadal
variability of tropical cyclone landfall in the
Philippines from 1902 to 2005 Published in
GEOPHYSICAL RESEARCH LETTERS, VOL. 36
7
Philippine problem
Always the same in the Philippines. Typhoons are
always coming and you can just adapt to it. If
you would like to live in the Philippines and not
experience a lot of typhoons move to Zamboanga.

Sea level increasesince the last ice age
16
During the ice age the ice area was 3 times as
large compared with today. The volume was about
2,5 times bigger. When it melted with the highest
speed the sea level rose with 1 2 meters/100
years.That rate of melting is impossible today.
17
How was it 1000 years ago?

19
During the last 100 years the sea level has
increased about 20 cm and that is a lot of water.
The sea surface is 70 of the earth.

Bangladesh
Sometimes we hear that some countries are
inundated by the water like Bangladesh and the
islands of South Pacific. How is it in
reality? Lets first look on Bangladesh a delta
landscape, a very flat land. Compare the blue and
red colors.
22
Coastland of Bangladesh
Bangladesh is growing every year.
23
How about the low lying islands in the Pacific?
24
Many have said that these islands will be covered
by the ocean in the future. How is it at the
moment? A scientific study last year showed that
many islands are growing in size in spite of the
sea level rise. Why?
25
Because of this fish, the parrotfish.
26
This fish eats the corals and spits out the coral
fragments and thus one fish makes 90 kg of sands
each year. The waves are transporting it to the
beach and the island is growing. But if you are
taking up the sand for house building maybe the
waves will erode the beach more instead.
27
Temperature rise
How much have you heard about the ice age? Three
times as much ice it is now. Why did it end?
28
The globe during the last ice age
29
How was the Philippines during the ice age?
Larger land area!
30
Other parts of the world
  • Himalayas and South America had more ice
  • Sea level 120 m lower.
  • Tropical rainforest smaller.
  • Tropical areas were 3 4 degrees colder.
  • Deserts were larger.
  • Australia was dryer

31
Temperature during 450 000 years
32
Every ice age was more than 100 000 years. Varm
periods called Interglacials were mostly short
periods 10 000 30 000 years. Today we have
lived about 10 000 years in a warm period and in
the future will have another ice age.

Conclusion 1
The climate has always been changing. We must
adapt to it.
41
Conclusion 2
Decrease the greenhouse gasses from our society.
For example use natural gas instead of coal when
heating or producing energy.
