- Weather versus climate (where is the temperature changing?)
- Global warming--average global increase in temperature
- Greenhouse effect and greenhouse gases (sources and sinks, climate vs weather), the atmosphere
- Glaciation (Valdez Glacier in Alaska, the Wallowas, a moulin in Greenland), cycles (precession, tilt, Eccentricity)
- Shots from the plane (ice sheet, ice sheet, glaciers, glaciers, fjord, coastline)
- Laws of thermodynamics
- First, energy can be neither created nor destroyed--it's just transformed.
- Second, transformation as suggested is usually from a 'higher' to 'lower' quality of energy (entropy). For instance, hydroelectricity is used to turn on a light bulb, which gives off heat--as well as light. The heat is often unusable, a 'waste product.' Where does it go??
- Some effects
- Key questions
- Is warming actually occurring? At what pace? Where? How fast?
- Is it caused by humans (the famous Keeling Curve)?
- Is it a social problem (what are some trends?)
- What are some anthropogenic causes?
- What groups are harmed (human and non-human species)?
- Who benefits from the status quo? (fossil fuel industries, automotive industry, utilities, petrochemicals/oil and gas, transportation, advertising, American consumers (and others in industrial countries), media, etc.
- 'Framing' global warming as a social problem
