1. The Greenhouse Effect

2. Draw and label a diagram of the carbon cycle Do it. Now!

3. Carbon Cycle

4. Analyze the changes in concentration of atmospheric carbon dioxide using historical records

5. Major Greenhouse Gases The Kyoto Protocol covers emissions of water vapor, carbon dioxide, methane, nitrous oxide, hydrofluorocarbons (HFCs)

6. Explain the relationship between rises in concentration of greenhouse gases and the enhanced greenhouse effect

7. Outline the Precautionary Principle 1992 Declaration on Environment and Development; the declaration includes the principle, "Nations shall use the precautionary approach to protect the environment. Where there are threats of serious or irreversible damage, scientific uncertainty shall not be used to postpone cost-effective measures to prevent environmental degradation. Those responsible for the change must prove that it will not do harm before proceeding

8. Evaluate the precautionary principle as a justification for strong action in response to the threats posed by the enhanced greenhouse effect (aka global warming) Do it. Homework!

9. Outline the consequences of a global temperature rise on arctic ecosystems. Effects include increased rates of decomposition of detritus previously trapped in permafrost = Inc. CO 2 expansion of the range of habitats available to temperate species, loss of ice habitat, changes in distribution of prey species affecting higher trophic levels, increased success of pest species, including pathogens
