<p> Global Warming: The Signs and the Science</p><p>1. What are some indications that global temperatures are increasing, particularly in polar regions?</p><p>2. What is the greenhouse effect? Is the greenhouse effect a natural phenomenon? Explain.</p><p>3. What are some of the primary emissions that act in enhancing the greenhouse effect?</p><p>4. About how long does CO2 produced today persist in the atmosphere before it is re-assimilated?</p><p>5. How will the population and economic growth patterns in China likely impact carbon emissions?</p><p>6. Do you think a developed country, like the U.S. that contributes a large proportion of greenhouse gas emissions, has any role in developing or influencing energy policy in emerging/developing nations? Why or Why not?</p><p>7. What are some of the health hazards associated with urban living and exposure in the urban life as shown in the video?</p><p>8. How is the idea of “heat transfer” in systems associated with alteration in global climatic patterns?</p><p>9. What kind of problems might climate change present for the petroleum industry and the distribution of hydrocarbon based products in Louisiana and the U.S.?</p><p>10. How might climate change and changes in local weather patterns influence food production?</p><p>11. Why do scientists in the video think that photosynthesis by trees won’t sufficient to absorb excess carbon dioxide emission if average temperature continues to rise?</p><p>12. How might global oceanic currents be altered if glacier and ice sheet formations in places like Greenland continue to melt at current rates?</p><p>13. What was the major goal of the Kyoto Protocol? </p><p>14. What role do you foresee for hybrid technologies in terms of reducing carbon dioxide emissions? </p><p>15. What type energy conservation techniques and “smart design” architecture practices are being implemented in construction of “greener” / energy efficient homes? 16. How does solar power actually help to create jobs and provide economic stimulus in the economy?</p><p>17. What is “net carbon sequestration”?</p><p>18. What is your opinion of the feasibility of the “artificial tree” carbon scrubbing technology as portrayed in the video?</p>
