1. What will happen to this stretch of land if sea levels rise even a few feet???
Tarawa atoll, Kiribati, is seen in an aerial view.

2. Fearing that climate change could wipe out their entire Pacific archipelago, the leaders of Kiribati are considering an unusual backup plan: moving the populace to Fiji.
Tong said some villages have already moved and there have been increasing instances of sea water contaminating the island's underground fresh water, which remains vital for trees and crops. He said changing rainfall, tidal and storm patterns pose as least as much threat as ocean levels, which so far have risen only slightly.
Oceans levels are rising about 1-2 mm each year.

3. East coast if sea level rose 17 feet

4. East coast if sea level rose 170 ft.

5. East coast as it was 20 000 years ago at the height of the last ice age

6. Florida if sea level rose 17 feet

12. Climate change: http://www3. epa. gov/climatechange/kids/basics/past
What does this mean?
What is the greenhouse effect?
What are the main gases involved in the greenhouse effect?

14. Some greenhouse effect is good:

16. To much green house effect can cause temperatures to rise:

17. What happens when energy is trapped by the gases?

18. Higher temperatures result in:

19. Yes, CO2 levels and methane levels have fluctuated in the past.
BUT these levels seem to be rising at an even faster rate….WHY?
How are human activities contributing to the increased levels of greenhouse gases?

21. Where does the CO2 come from?
Burning of fossil fuels for
Transportation
Generating electricity
Heating
Agriculture
Deforestation

24. Who is emitting the CO2 ? How might this change as India and China continue to develop?

25. Where does the methane come from?
Methane is a much more ‘efficient’ greenhouse gas than CO2, therefore a small increase in methane has a larger effect than the same increase in CO2
Some methane is released into the atmosphere when oil is distilled (separated) into its various components.
Some is coming ‘out of solution’ as the oceans heat up
Some is coming out of the soils as permanently frozen soils (permafrost) warm up.
Much comes from agriculture – from digestive processes of cattle, sheep, goats etc.

27. Is the current warming ….
A natural part of earth’s cycle?
Agriculture – too many cows
3. Man made causes as a result of increased CO2 levels from:
Industrial revolution
Transportation
Deforestation
Overpopulation

28. Population growth??

29. What can YOU do???

30. You must know: What the term ‘climate change’ means
What gases are considered greenhouse gases
How those gases cause earth’s temperature to rise
Consequences of rising earth temperatures
How humans are contributing to this change
