what is global warming
What is globalwarming?
  • Global warming or climate change is the gradual increase of the average temperature of the Earth
  • The average temperature of the Earth's surface is around 59˚F or 13 ˚C.

Greenhouse Gases in the atmosphere hold in heat

      • Without these gases, the Earth’s surface temperature would drop to around 0 ˚F.

the atmosphere
The Atmosphere
  • The Earth is surrounded by a thin layer of gases
      • Oxygen
      • Carbon Dioxide
      • Nitrous Oxide
      • Methane

Greenhouse gases

atmosphere
Atmosphere
  • Supplies gases required for life
      • Oxygen
      • Carbon dioxide
  • Offers protection from the sun’s ultraviolet radiation
  • Helps control Earth’s temperature by trapping solar energy next to the surface

the effects
The Effects
  • Water levels will rise in oceans
  • The timing of the seasons will change
  • Increased spread of disease
  • Stronger hurricanes and storms
  • Animals change behavior
  • More plant and animal species will become extinct
  • Allergies get worse

congratulations26
Congratulations!!

You are correct!!

Next Question!

slide27
Greenhouse gases cause global warming by:
  • Absorbing and reradiating heat from infrared rays
  • Causing the atmosphere to catch fire
  • Absorbing the water in the atmosphere
  • Reflecting solar rays

are you contributing to the climate change
Are you contributing to the climate change?
  • Check your electric bills for the past year. For each kWh allow 0.8kg of carbon dioxide.
  • If you flew on a commercial plane in the last year, add 0.35 kg for each kilometer flown for each person who flew with you.

in the classroom
In the classroom
  • This presentation was created for middle or high school level students as an introduction to global warming or can be used as a classroom supplement. After viewing this show, students should have developed an awareness about global warming, what’s causing it, the effects of it, and prevention strategies.

methane ch 4
Methane-CH4
  • A gas that is emitted from the following sources:
    • Volcanic activity
    • Natural gas fields
    • Solid waste landfills
    • Byproduct of biomass
    • One of the ingredients found in a burp!

Read this article:

Cows that burp less aid climate fight!

More information on Methane

methane
Methane
  • The early atmosphere of the Earth had 1000x more methane that what is has now and therefore, no life existed on the planet.
  • Oxygen was not produced until photosynthetic bacteria evolved at a later time.

nitrous oxide n 2 o
Nitrous Oxide- N2O
  • A gas that is emitted from the following sources:
    • Burning fossil fuels
    • Use of fertilizers
    • Burning biomass
    • Can be used as a mild anesthetic for minor surgeries

Also known as laughing gas!!
