What is global warming?• 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 Earth is surrounded by a thin layer of

gases

• Oxygen

• Carbon Dioxide• Nitrous Oxide• Methane

Greenhouse gases

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• 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 e

xtinct• Allergies get worse

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• 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.

Lessons and assessment ideas

• Debate the bias of global warming. Study both sides of this scientific controversy and then share your facts and information with your classmates.

• Act out the process of global warming• Create a song or jingle about global

warming. • Perform an experiment, gather data and

draw up your own conclusions regarding global warming.

Carbon Dioxide- CO2

• Accounts for 80% of greenhouse gases emissions

– Enters atmosphere by1. Carbon cycle2. Burning fossil fuels3. Deforestation4. Cement production

Back

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

• 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.

Back

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

surgeriesAlso known as laughing gas!!
