Thirdly,
what are the possible consequences caused
by excessive greenhouse effect?
It directly results
in quick increase of the average global temperature.
Today,
the increase in the Earth's temperature
is increasing with unprecedented speed.
To understand just how quickly global warming is accelerating,
consider this:
during the entire 20th century,
the average global temperature
increased by about 0.6 degrees Celsius,
while by using computer climate models,
scientists estimate
that by the year 2100
the average global temperature
will increase by 1.4 degrees to 5.8 degrees Celsius,
which is rather a big leap from the last century.
Meanwhile,
a majority of the scientists agree
that even a small increase in the global temperature
would lead to significant climate and weather changes,
affecting cloud cover,
precipitation,
wind patterns,
the frequency and severity of storms,
and the duration of seasons.
