2. Global warming is when the earth
heats up (the temperature rises). It
happens when greenhouse gases
(carbon dioxide, water
vapour, nitrous oxide, and methane)
trap heat and light from the sun in
the earth’s atmosphere, which
increases the temperature. This
affects all life on earth.
(Humans, animals, plant life etc)
3. The greenhouse effect is
when the temperature
rises because the sun’s
heat and light is trapped
in the earth’s
atmosphere. This is like
when heat is trapped in
a car. On a very hot
day, the car gets hotter
when it is out in the
parking lot. This is
because the heat and
light from the sun can
get into the car, by going
through the
windows, but it can’t get
back out.
This is what the
greenhouse effect does
to the earth. The heat
and light can get
through the
atmosphere, but it can’t
get out. As a result, the
temperature rises.
4. Global warming is the end
result of man for using up
resources. There are many
reasons why global
warming occurs today. One
of the major reasons is the
consumption of too much
energy. When you do not
unplug appliances(example
TV) before going to
bed, this eats up more
electricity, or cars running
on gas or petrol. All of
these activities require
energy. To produce
energy, we use up fossil
fuels that are dug right
from the ground.
Fossil fuels are produced
from decaying plants and
animals. When oil from
fossil fuels is burned, it
creates a dreadful odour
that pollutes the air we
breathe. Moreover the end
results of used up fuels can
also pollute our water. As
energy is used up the
chemicals emitted cause
the Earth to behave
similarly to a
greenhouse, thus the term
greenhouse gases.
5. In global
warming, excessive heat is
trapped here on
Earth, damaging crops and
trees, and habitats of
animals as well. A rise in
the temperature in the
ocean waters affect even
the glaciers, and once
these melt completely not
only will the animals
residing there lose their
home, the melted ice caps
can cover nearly more than
half of the Earth’s terrain
and population.
Polar caps are now said to
be thawing more than five
times faster than before.
6. The consistent burning
up of fossil fuels will
bring environmental
disasters and calamity
to us all. Today most
people do not care
much about the
environment, and
continue to use up
energy without any
regard for their
surroundings. We
experience heat waves
even during the cool
months.
Droughts have been
reported, and are
widespread. Climate
change causes
hurricanes, leaving
tens of thousands of
people
homeless, missing or
dead. Global warming
will cause more
natural disasters.
Example: Tsunami
