Climate Shift, Global Warming, Greenhouse Gases

1. 200YEARS OF CLIMATE
CHANGE
Greenhouse gases and the END OF THE WORLD!!!!!!!
Well, Floods and Droughts at least.

2. None Like It Hot!
▪ Play this vid clip (2 minutes), repeat if desired.
▪ http://www.youtube.com/watch?v=2taViFH_6_Y
▪ What happened in this video?
▪ What is the cause of the problem?
▪ What impossible solution is presented?

3. Greenhouse Gases
These are gases that absorb infrared radiation
Chlorofluorocarbons and CO2 and Nitrous Oxide
and Methane, etc.
Turns solar radiation into heat in the atmosphere
Heat absorbed by planet’s surface and bounces
back, reradiates in all directions
Traps much heat within the planet’s atmosphere

4. Here’s How It Works

5. History of Greenhouse Gases
▪ What was happening in history
around the time of the rise in
carbon emissions?
▪ What caused this rise?
▪ Suggest what this chart will
read in the year 2100.

6. Human Impact
▪ Remember why it gets colder the higher the elevation?
▪ Sort of the same thing with Greenhouse Gases.
▪ We are adding a tremendous amount of substance to the
atmosphere of Earth, everyday, everywhere, all of the time.
▪ CFC’s (chlorofluorocarbons) from Acs and refrigerators
▪ CO2 from breathing, huge population and deforestation
▪ Methane from bacteria breaking down organics, end of digestion
▪ Nitrous Oxide from fuel consumption and fertilizers
▪ Water Vapor/Humidity from increased heat

9. Analyze the charts:
Where are IC’s and DC’s now? Where are they predicted to be
in the future? Why?
Suggest why Japan has a lower per capita emission rate than
the United States.

10. Enjoy this scenic photo of downtown Beijing, China.
China is a Developing Country experiencing dangerous levels of air
pollution.

11. Heat Projections: Melting Ice
Contrast these two images. What is
different?
Compare these two images. What is
similar?
Where is most of the heat change
occurring?
What is found in that region?
How will that heat change effect
Earth?

13. Melting ice diminishes the
range polar bears can hunt
in.
Their habitat shrinks, they
get trapped on shrinking
ice sheets, they end up like
this poor guy.
It is unknown how many
bears are drowning in the
Pacific Ocean each year.

14. Florida: USA prediction
Suggest ways a
government could
prepare for the
flooding effect
predicted here?
Will Indonesia be
effected similarly
or differently?
Explain.
Suggestions?

15. Leaving a lighter CARBON FOOTPRINT.
Explain 10 specific ways we can.
