3. Introduction
• The greenhouse is working with
increasing temperature on the globe
in recent decades. Recent research has
indicated that the twentieth century
was the warmest of the last 500 years.
• Researchers say that in the near
future, the temperature rise caused by
global warming will cause the melting

of the poles and rising sea levels.

4. Definition
• When everything goes normally, the
greenhouse effect is a natural
phenomenon, caused by certain gases
in the atmosphere that keeps our
planet with the right temperature, it
retained only a small portion of
sunlight that reaches Earth. Image

• But at present the greenhouse effect is

the increase in temperature caused by

6. Consequences
• Growth and development of deserts:
the increase in temperature causes the
death of several plant and animal
species, unbalancing various
ecosystems.
• Increase of typhoons and cyclones: a
temperature increase causes more
evaporation of water occurs in the

oceans, increasing these types of

7. Consequences
• Increase in sea level, with the
temperature increase in the world, the
melting of the poles. By increasing the
level of the ocean waters will
submerge many coastal cities.

8. Curiosity
• If there were no greenhouse
effect the Earth's temperature
would be between -32 º C and
-23 º C which would make the
most of life on earth is not
existence.
