2. Also referred to as: ‘A CAR WITH THE WINDOWS ROLLED UP ON A SUNNY SUMMER DAY’ EFFECT

4. 1. LIGHT enters the atmosphere 2
1. LIGHT enters the atmosphere 2. Light is CONVERTED TO HEAT when it strikes certain surfaces 3. SOME OF THIS HEAT is trapped by gases

5. IS GLOBAL WARMING REAL? YES
ALL MAJOR SCIENTIFIC STUDIES AGREE THAT HUMANS ARE CAUSING CARBON DIOXIDE TO INCREASE AND THAT TEMPERATURES HAVE GONE UP

6. AT MINIMUM THERE IS A STRONG CORRELATION BETWEEN CARBON DIOXIDE AND TEMPERATURE … IF NOT AN ACTUAL CAUSE AND EFFECT RELATIONSHIP

7. COMPLICATED VARIABLES INCLUDE CLOUD FORMATION ICE MELT RATES
OCEAN CIRCULATION PATTERNS
OCEAN CHEMISTRY
CHANGES IN VEGETATION
SEA LEVELS
AND MANY OTHER FACTORS.

8. G.H.G.
GREEN-HOUSE GASES
CARBON DIOXIDE (CO2)– created by the burning of fossil fuels and the burning of forests
METHANE – (CH4 - Flatulence) result of raising animals for food
C.F.C.’S, NITROUS OXIDES AND WATER VAPOR

9. Levels of CO2 from 1958 to Present

10. CARBON DIOXIDE FLUCUATES UP AND DOWN EACH YEAR.
LOW IN SUMMER WHILE PLANTS ARE ACTIVE
HIGH IN WINTER WHEN PLANTS ARE NOT ACTIVE AND WHEN MORE FOSSIL FUELS ARE BURNED

11. CARBON DIOXIDE OVERALL INCREASES FROM YEAR TO YEAR
PARTS PER MILLION (PPM)
PPM
INCREASE CAUSED BY BURNING OF FOSSIL FUELS AND DEFORESTATION

12. Deforestation
Causes 25-30% of yearly Carbon Dioxide

13. CFC’S CHLORO FLUORO CARBONS
IN PAST WHERE FOUND IN REFRIGERANTS, AEROSOLS AND STYROFOAM
TODAY ARE NO LONGER MADE – BUT SOME ARE STILL IN PRODUCTS MADE BEFORE 1990

14. CFC’S TRAP HEAT – CONTRIBUTE TO GLOBAL WARMING
LARGER PROBLEM - THEY DESTROY OZONE WHICH PROTECTS US FROM THE ULTRAVIOLET RADIATION OF THE SUN WHICH CAN CAUSE SKIN CANCER

15. WHY WORRY?? CHANGE IN CLIMATE PATTERNS
RESULTS IN DROUGHTS AND HEAT WAVES
COULD EFFECT FOOD PRODUCTION
POSSIBLE FLOODING OF SOME COASTAL AREAS
SPREAD OF CERTAIN DISEASES

16. Species Extinction

17. Effects on life Phytoplankton growth Effects of climatic changes
Ocean stratification
Contribute to global warming
The food chain
Effects of climatic changes
on Arctic Plants

18. Coral Reefs Bleaching

19. Melting Ice Sheets As ice melts, trapped CO2 released.
In Greenland earthquakes occur due to weight of ice disappearing

20. Glaciers 20% reduction in size from 1962 – 2001 for 466 glaciers
Can mean flooding and then drought for regions near glaciers
Photos taken in 1913 (top) and 2005 (above) show the decline in Shepard Glacier in Montana's Glacier National Park.

21. Myths about global warming
Scientists don’t agree
Have to choose between economy and environment
Too big a problem for anyone to do anything about
THESE ARE ALL FALSE

22. WHY SHOULD THE USA CARE?
WHILE WE REPRESENT ONLY 4% OF THE WORLD’S POPULATION – WE CREATE 22-36% OF THE WORLD’S G.H.G.

23. WHAT IS BEING DONE? KYOTO TREATY CHICAGO CLIMATE EXCHANGE
INDIVIDUAL EFFORTS

24. KYOTO PROTOCOL United Nations first talked about in 1988
Written in 1997
Went into effect 2005
THE U.S.A. AND AUSTRALIA DID NOT SIGN IT – OVER 80 OTHER COUNTRIES DID

25. U.S.A. WANTED STRICTER STANDARDS PLACED ON CHINA AND INDIA
AFRAID MIGHT COST SIGNIFICANT MONEY
HOWEVER SEVERAL STATES HAVE AGREED TO TREATY’S STANDARDS

26. EUROPEAN UNION ONLY GROUP TO ACTUALLY LOWER EMISSIONS
TREATY’S GREATEST SUPPORTER

27. CHINA DEVELOPING NATION STATUS
WITH 1.3 BILLION PEOPLE IS WORLD’S LARGEST PRODUCER OF COAL
HAS MADE ATTEMPTS TO LOWER EMMISIONS

28. INDIA DEVELOPING NATION STATUS
EMISSIONS HAVE INCREASED BY 50% SINCE SIGNING TREATY

29. RUSSIA MOTIVE TO JOIN LINKED WITH TRADE PRACTICES WITH OTHER COUNTRIES
AS ITS ECONOMY HAS SLOWED DOWN – HAS SOLD ITS UNUSED EMISSIONS TO OTHER COUTRIES

30. JAPAN ACCOUNTS FOR 8% OF WORLD’S EMISSIONS
HAS NOT MET ITS GOAL OF REDUCING EMISSIONS BUT HAS INVESTED HEAVILY ON NEW TECHNOLOGY TO ATTEMPT TO MEET GOAL

31. CHICAGO CLIMATE EXCHANGE
VOLUNTARY PROGRAM OF COMPANIES ATTEMPTING TO REDUCE EMISSIONS WITHOUT BEING FORCE BY THE GOVERNMENT.

32. INDIVIDUAL EFFORTS REDUCE USE OF OIL and COAL MADE ELECTRICITY
RECYCLING
PLANTING OF TREES

33. The End
