- problem teams (diads)
First, some terms:
- Climate change
- Global warming
- Climate Crisis
Which is most accurate?
Most scary?
Most likely to cause change?
Recall: energy->water->food->culture
Global warming will impact and be impacted by each of these:
- Energy: how we got into this mess-fossil fuels, starting around 1850, burning plants that consumed CO2 eons ago as part of photosynthesis, releasing their trapped carbon (coal, oil, gas)
- Water: freshwater will become more resource constrained, sea levels will rise, oceans will become acid
- Food: locations to grow will become constrained (e.g. Pearl River Delta, desertification), poor people will not have options for farming or fishing
- Culture: coastal flooding will cause huge migrations of mainly poor people, but renewable energy could de-centralize energy structures (e.g. solar energy in Africa)
Mechanics: How this all works
- Solar radiation is visible, UV, infrared and others, virtually all pass through our atmosphere to reach the surface
- Surface is either reflective (high albedo: ice) or absorbing (low albedo: water, soil)
- Water and soil absorb the radiated energy and re-radiate it back as heat (infrared radiation, like the dashboard of your car)
- This heat radiation is captured by the CO2 in the atmosphere, re-radiating back down warming the planet
- Some CO2 is needed to warm our planet above freezing, too much is warming the planet: global warming
Impacts:
- melting of polar ice (changes albedo to absorb more)
- warming of oceans (expanding water=sea level rise, expels dissolved gases)
- ocean acidification (CO2 + H2O -> carbonic acid)
- more evaporation (stronger, more frequent storms, more latent energy in the atmosphere)
- desertification and drought (shifting air patterns)
- salinization of coastal/delta farmlands (salt water intrusion)
- melting of permafrost-releases methane, a potent GH gas (greenhouse gas)
- melting of deep ocean methane hydrates-releases more methane
- biodiversity and habitat loss
- severe storms
- increased wildfires
- wild feedback loop
- impact increased by deforestation (e.g. amazon rainforest)

Team, many questions here, which we will break into several assignments:
Part One:
- What river is China planning to divert that will cause conflict with India, and why are they doing this?
- Why did Brashears go back to that specific site to take the photo, and what did he see? What possible explanations are there for this? Take both sides of the climate crisis argument in your answer.
- What was so surprising in the dorky 1958 movie? Was this common knowledge back then? How can you tell?
- How does the cheapness of energy influence public opinion?
- Is the climate crisis an energy issue, a tree issue, an albedo issue, an ocean issue, or a permafrost issue?
- What happened at the Kyoto meeting? What was the most embarrassing part? Why did the US behave so?
- Why would China's growth outweigh any changes the US might make to change carbon emissions?
- What is Geely? Where? What model is their biggest seller? Is this scary? Why? What did their director say?
- How many coal plants does China create every week according to the video, and how many years will they be emitting CO2?
- Dr. Ling Wen says 30% growth over 5 years. What is the doubling rate for this in years? (divide 70 by the percent growth).
- Why is his line "if we can" so scary? What are his responsibilities, in what order?
- In what year will India's population exceed that of China? Why?
- What is the third largest contributor to greenhouse gases? Where?
- What reduction in CO2 did the Indian guy say they could do by 2050? What is the growth rate?
- What did Sunita Narain say about this? Why is this not sustainable?
- What did Pachauri say and what are his reasons?
- What did the US negotiators say and why is this unfair? What did China say?
- Google Senator Inhofe, and find out why he was a global warming skeptic. Where did his money come from?
- This video was filmed in 2008. What was the position of each presidential candidate then?
- What did Jeffrey Sachs say, and why is it important?
- How many tons of coal are mined in the Powder River basin each day, and about how much CO2 does this release?
- The director of the West Virginia power plant (Charlie Powell) says: "we produce 1300 kilowatts of power every hour" which is like saying "my car goes 60 miles per hour every hour". What is wrong with his statement?
- How many pounds of Coal power your TV for one hour? What percentage of power in the US comes from coal in 2008 when this was created?
- Analyze the term "clean coal" from both sides of the argument. What are the motives of each side and why?
- Senators Byrd and McConnell represent which states? What is their bias?
- What is IGCC? Where is it located? Has it been tested? Where would they inject the ground? Why is this dangerous?
- Are we "carbon capture ready"? Where would this be tested first, and why is it problematic? If pipelines were used, why would these be dangerous?
- How many tons of CO2 does the US emit every day in 2020?
- Why is the US is called the "Saudi Arabia of Coal"?
- What is the second largest emitter of greenhouse gases? Now list the top three in order.
Part Two:
- What are CAFE standards, and what does it stand for?
- How did auto manufacturers get around the CAFE standards since the Ford Explorer came out?
- What was John Dingell's motive and where was he from?
- Was his responsibility only to his 800,000 citizens or to the country, or the planet as a whole?
- What MPG was the terminator seeking for California?
- In the 1970's all cars in the US came in two flavors: "49 state" or "CA". Why?
- What is the clean air act?
- What was the target of the CA emissions standards?
