1. Agenda 11/9 and 11/13 Greenhouse gas video Evaluation of arguments
Coral Reef Case Study
Homework: WB Section #130, 131, IA work
Turn in: Video notes

2. How do greenhouse gases relate to global warming?

3. What are the arguments against climate change?
Complex the activity by analyzing your own views first
Then you will evaluate the reliability of various sources using rubric

4. Greenhouse Gases
Carbon dioxide and water vapor are the two most significant green house gases
Methane and nitrogen oxides have less impact
The ability of a gas to absorb long wave radiation and its concentration will control how big of an impact it has in the atmosphere

5. Carbon Dioxide Levels
There is a correlation between rising atmospheric concentration of carbon dioxide since the start of the industrial revolution 200 years ago

6. Where does the carbon dioxde come from?

7. Temperature and CO2 levels

8. Coral Reefs and Rising CO2 Levels
With a partner, you will create an informative poster that outlines why an increase in CO2 levels is causing damage to the coral reefs
Use RELIABLE sources only! (NASA, EPA, Smithsonian ocean)
Include the following on your poster:
How humans are causing an increase of CO2 levels (with evidence)
How CO2 levels get into the ocean
How CO2 in the ocean causes ocean acidification
How ocean acidification damages coral reefs
The current threat to coral reefs
Any plans or solutions to the problem
The research needs to be reliable and evidence based!!
Today: Finish research
Next Class: Design a poster to appeal to the student body
