Global Warming An environmental dilemma

Global WarmingAn environmental dilemma
2
What is Global Warming?

• Global Warming is
• A change in the Earths climate resulting in a
  thinning ozone layer, melting glaciers, changes
  in nature, and rising temperatures.

3
The Ozone Layer
4
Ozone Layer?

• The Ozone Layer is a layer of the upper
  atmosphere, which blocks most of the suns
  radiation. It is located in between the
  Stratosphere and Troposphere.

5
Ozone Depletion.

• Ozone Depletion
• The destruction of the Ozone Layer.

6
Causes of Ozone Depletion.

• Chlorine and Bromine released from CFCs.
• Chlorofluorocarbons (CFCs) man made compounds.
• Natural events is a temporary cause of Ozone
  Depletion.

7
Greenhouse Gases.

• Greenhouse gases are chemical compounds (gases),
  that naturally blanket the earth, and absorb the
  suns radiation (heat).

8
Ozone Depletion Greenhouse Gases Disaster.

• Ozone Depletion allows more of the suns
  radiation to come in through the atmosphere of
  the Earth and the Greenhouse Gases absorbs the
  radiation, trapping heat in the Earths
  atmosphere.
• Thus, Earth gets hotter, hotter, and
• .

Fitting it Together!

• GLACIERS

11
Glaciers and the Sun

• The sun heats the ocean around the glaciers
  causing glaciers to melt
• When the glaciers melt, the sun cant reflect off
  of the glaciers and the rays get trapped in the
  ozone layer

12
Glaciers and snow

• When glaciers melt, snow usually replaces them
• Because glaciers melt so fast, the amount of snow
  needed is not being produced to keep up with the
  speed at which they are melting

13
What happens?

• Glaciers melt at faster rates
• An important factor in glaciers melting are
  rising temperatures
• As temperatures increase, the weather becomes
  warmer, and glaciers melt faster
• Life in polar regions are dying

14
Facts

• Sea levels are expected to rise at least 4 feet
  in the next 100 years
• This would cause many places to flood
• Some would be underwater or partially underwater
• -For example Florida, North Carolina,
  California and Delaware. There would also be
  many islands partially underwater or completely
  underwater, as well as various countries, such as
  Bangladesh and Indonesia

• NATURE

20
Causes

• Rising temperatures
• Carbon dioxide
• Humans

21
Effects of Global Warming on Nature

• Deforestation
• Animal endangerment
• Human survival declines

22
Deforestation

• Humans
• Forest fires
• Drought kill trees

23
Wildlife

• Animals become extinct
• Population of certain animals grow

24
Human Life

• Poverty
• Conflicts
• Necessities become
• scarce

25
Rising Temperatures
26
Rising Temperatures are responsible for
Expanding deserts
27
Melting glaciers
28
Rising sea levels
29
Over Time

• Earths temperature has been increasing
• Increasing at a faster rate since 1950s

30
Temperatures have been increasing since 1950s
31
Temperature since 1880
32
Temperature Predictions up to 2130
33
Effects

• In 2000
• Heat wave hits Europe
• Temperatures reached
• up to 111ºF
• Antarctica
• Warming is five times greater
• Made almost entirely of ice

34
Statistics

• Year 2080
• Temperatures will
• raise by 5ºF
• This could lead to rising
• sea levels
• Shortages of resources
• Homes becoming destroyed,
• people being homeless

35
Survey

• Who likes guacamole? Or Avocadoes?
• Who likes baseball?

36
If global warming continues

• Guacamole could possibly cease to exist due to
  rising temperatures that harms the avocadoes used
  to make the dish
• Baseball can become a distant memory if the ash
  trees bats are made from continue to disappear
• Conflicts with other regions could develop due to
  diminishing resources. Such conflicts have
  already been witnessed

• How can we eliminate global warming?

38

• While Global Warming can never truly be
  reversed, there are ways some ways to solve most
  of the problems it creates. Here are some ways

39
Reduce, Reuse, Recycle

• Reducing waste helps eliminate 1000 pounds worth
  of Carbon Dioxide emission.
• Recycling also helps reduce Carbon Dioxide.
• Reusing helps you save money, while also reducing
  Carbon Dioxide.

40
Use Energy Star Lights

• Switching to Energy Star, helps you save money
  and eliminate the 100 pounds of Carbon Dioxide.

41
Do Not Waste Electricity

• Turning of the light equals less energy being
  used.
• Meaning, it can be conserved for later use.

44
Global Warming

• You have the mind, the spirit, and the will to
  make a positive difference. Leave a helpful
  impact on the world. Tell your friends about
  global warming, write your congressman, and
  become eco-friendly.
• A positive deed starts with a positive idea.
