3.  It was said that the Earth is so big that you
can not do significant damage, but not
anymore.
 What is the most vulnerable part of the
ecological system?
› ATMOSPHERE
 So thin is its composition that we can change
it.
 This is the basis of global warming.

4.  The Sun's radiation comes in waves of light
that warms the Earth.
 Some of the radiation that is absorbed and
warms the Earth back into space as infrared
radiation.
 Part of this radiation that comes out is
trapped by the atmosphere and retained.

5.  What this does is keep the temperature and that the
Earth is safe to stay alive, and that's good.
 The trouble is that by becoming thicker atmosphere, all
the contamination of human beings, more infrared
radiation is trapped and heats the atmosphere around
the world.

8.  Roger Revelle, was among the first people who
set out to measure carbon dioxide in the
atmosphere.
 After 7.8 and 9 years of studies could look at
the pattern that was developing in up and down
every year.
 Why go up and down every year?

10.  If you see the planet's land mass is mostly in
the north of Ecuador as well as most of the
vegetation.
 When the Northern Hemisphere is tilted
toward the sun, in spring and
summer, leaves and breathe out carbon
dioxide.
 This causes the amount in the atmosphere
decreases.

11.  What happens when the
northern hemisphere is
tilted away from the sun?
 As the leaves fall and emit
carbon dioxide.
 As a result, the amount in
the atmosphere rises.
 Carbon dioxide was first
measured from 1958 to
today.

12.  1000 year to 2005 carbon dioxide has
increased by over 40%.
 Global warming has increased over 80%.
 When there is more carbon dioxide the
temperature is warmer.
 If we travel back 650.000 years we see that
there are 7 ice ages the carbon dioxide has
never gone from 300 parts per million.
 Today is beyond the natural.

13.  Temperatures are caused by:
› Floods
› Drought
› Storms
› Hurricanes
› Tornadoes
› Earthquakes

14.  If the ocean temperature rises, storms get
stronger.
 Such as:
› Frances
› Jeanne
› Ivan
› Tornadoes
› Emily
› Dennis
› Katrina

16.  See that hot pink on the
map above?
 That color is new.
 While March was warmer
than average but not as
much as, for example,
2010 or many of the
months in 2010 (which
broke numerous
records), the Arctic
(where the most warming
has been predicted by
climatologists) did see
some pretty
tremendously warm
temperatures (relatively
speaking).
 As a result, climatologists
had to add that hot pink
color.

22. Effect of Global Warming

31. Earthquake
Geological changes related
to climate can
also cause "eruptions of
methane," the release of a
potent greenhouse gas, curren
tly stored in solid form
under the seabed and layers
of permafrost are melting, in
amounts greater than the
whole carbon dioxide (CO2)
from the air today.

32.  Broke off several pieces of glacier
ice Sulzberger, who according to historical
records had not suffered any break in at least 46
years.

41.  Changing bulbs
 Less driving
 More recycling
 Checking the gums
 Do not use hot water

42.  Avoid products with lots of packaging
 Adjust the thermostat
 Planting a tree
 Turn off and unplug things electronic
 Fewer pregnancies
 Being part of the solution
