Answers to the Assignment Questions

1.) Fossil fuel usage, industrialization, CO2 levels, and average temperature are all directly related. Each has increased alongside the other. (And though these trends have a mathematical relationship, I stand by my earlier statement that trends are not sufficient proof to pin total responsibility on humans. An exacerbated natural trend is an equally if not more plausible interpretation of these trends)
2.) The Kyoto Protocol is an international agreement under the UN intended to reduce world CO2 emissions. This is intended to occur either through lowering emissions directly, or by buying and selling "Carbon Credits" in the international community. Major signatories: China, Canada, India, major members of the EU, and Russia. Note the absence of the US and Australia. (source: Wikipedia)
3.) Three possible effects of global warming are vastly more powerful storms, increased droughts/ heat waves, and rising sea levels.
4.) Three ways to reduce personal energy consumption: Use CFL bulbs, use appliances prudently by turning them off when not in use, and use a programmable thermostat to reduce furnace usage when it's not needed.
5.) A new technology that could change energy use is the hydrogen-based economy. Using renewable resources to produce electricity for clean electrolysis of water would provide hydrogen without harmful emissions. Hydrogen would then be the primary source of energy; it would replace gasoline through fuel cells in cars. It would replace batteries through small-scale fuel cells. Essentially, our energy economy would operate on the energy of electricity produced through renewable sources, which is conveyed to the market in the form of hydrogen. Forgive the whimsical nature of this answer, but such an economy would require a Herculean effort far beyond that of any of the greatest public works projects ever. Though it's possible, it's a long, long way off in the future.
