Global Warming

Global Warming

• Nothing is scarier than this.

What is global warming?

• Global warming is a process of heating up the
  Earth.
• This is also known as the greenhouse effect
  because its effect is like a greenhouse. Just
  like a greenhouse, global warming doesnt make
  heat but instead, they trap the heat given by the
  sun.
• It is cause by some gases in the Earth that we
  created. Global warming is caused by us.
• There are lots of consequences that were cause by
  these gases that can and definitely affect the
  Earth, animals and us.
• There are lots of gases that cause Global warming
  these 4 were the deadliest. They are called CO2,
  CFC, CH4 and nitrogen oxide.
• Global warming creates stronger hurricanes,
  temperatures will rise causing Glaciers to melt
  raising the sea level and there are more chances
  for each animal to be extinct
• In august 2005, hurricane Katrina slammed into
  the islands. That is the beginning of the period
  of consequences.

How to make global warming?

• They created a layer around the Earth
• Some heat from the sun cant even touch the
  surface of the Earth but some is able to
• The heat will bounce of the surface and out into
  space but some heat will be trapped in like a man
  in a prison
• As time goes by, more and more heat will be
  trapped thus, making the Earths temperature raise

CO2

• The full name for CO2 is Carbon dioxide. Carbon
  dioxide is the most common greenhouse gas in
  earth.
• It is created by deforestation because the trees
  release carbon after it is cut up and trees
  breathe in carbon dioxide to make oxygen. Without
  trees, we wont survive.
• It can also be created by factories because they
  use fossil fuels. That means they burn old stuff
  like coal to make things for us like electricity.
  If we do that, huge amounts of Carbon dioxide
  will be released.
• It damages the ozone layer so more heat will come
  in which means more UV rays will go to Earth that
  will cause skin cancer.
• It makes a barrier with the other gases around
  the Earth to trap heat. This is why the
  temperature is rising.

5
Methane

• Methane is also a type of greenhouse gas
• It came from waste dumps
• Just like CO2, it damages the ozone layer
• Methane is a very attractive fuel because of its
  clean burning process
• Methane can be found in the crusts of the Earth
• Methane is not toxic but its flammable and can be
  dangerous
• When averaged over a hundred years, each Kg of
  methane is 23 times as much as the same mass of
  carbon dioxide.

6
CFC

• CFC is also a greenhouse gas
• CFC is different because as it damages the ozone
  layer, it stays there in the atmosphere and keeps
  damaging it while the other gases will wear off
• We get CFCs by refrigerators and aerosols.
• CFC are haloalkane of chlorines and fluorine.

7
Nitrogen Oxide

• Nitrogen oxide is the last of the greenhouse
  gases
• Nitrogen oxide come from cars
• It is a colorless and inflammable gas
• Nitrogen oxide can also be known as laughing gas
• Per unit of weight, Nitrogen oxide is 296 times
  the effect of CO2
• Nitrogen oxide also damages the ozone layer,
  causing more UV rays to go into Earth.

What do we do to stop global warming?

• Global warming is a very hard thing to stop
• If we stop global warming, we will have less
  food, less efficiency, less speed, less
  competitions, less resources and less fun
• We cant stop global warming. The onl thing we
  can do is to reduce it.
• Use more bikes, eat less, recycle so theres less
  factories and use natural energy like solar, wind
  and hydro energy to generate electricity instead
  of using fossil fuels to make them
