Earth’s average The total area of glaciers
atmospheric temperature has decreased more than
has risen about 1 degrees 3 million km2 in the past
Celsius since 1981 30 years
3. Future Prediction
If global warming continues at the same
rate, it is predicted that the atmospheric
temperature will increase about 2.4~6.4
degrees Celsius (36~43.5 degrees
Fahrenheit) by 2100.
If the amount of CO2 would double, the
area of the glaciers would decrease by
60%
4. Cause of Global Warming
90% of the causes of global warming is
the greenhouse gas which humans
produce, especially CO2 and methane gas
The greatest cause of global warming,
CO2 is produced by burning fuel,
transportation, industry, etc.
5. What Will Happen?
~Desertification~
Desertification is the process where healthy
land with plants growing turns into a desert
because of lack of rain.
In the near future, one-fourth of the Earth will
be covered with deserts.
This is caused by changes in weather
conditions, which are caused by human
activities.
7. Ozone Depletion
No organism on Earth can survive without an
ozone layer.
Long time ago, there was no ozone layer
around the Earth, and there were no life. As
the layer formed, life developed on Earth.
8. Cause of Ozone
Depletion
Freon gas is the cause of ozone depletion.
Freon gas is produced mostly by the use of
human tools such as using air conditioning,
and refrigerator.
Gas reaches the Earth’s atmosphere in about
20 years.
9. What We Have to Do
Global warming is not a problem in the
future. It is already affecting us today, and
will continue to in the future.
We can decrease the amount of greenhouse
gases by using energy more efficiently;
using tools and clothes longer; traveling by
walking, or on bikes to closer destinations;
stopping lights and water when not using,
etc.
