Document Summary

As we develop greater knowledge of the potential impacts of climate change, everyone from public agencies to private companies to families and individuals are starting to consider whether and how they should prepare. The climatic changes we are discussing here are those associated with the increased loading of greenhouse gasses into the atmosphere. These loadings, much of which occur due to fossil fuel burning, mean that more of the sun"s energy either directly or via re-radiation from the earth, will remain in the atmosphere and not get vented back into space. As more heat is captured, the global climate will slowly warm. A slow increase in global average mean temperature is one possible result of climate change. With increased energy in the atmosphere, there will be more evaporation of surface waters (primarily the ocean), so future storms will have more water and energy available to them and be more intense.

Energy Choices

Worldwide energy consumption varies dramatically, but the impacts are shared by all. The most commonly used fuel sources for energy around the world are the fossil fuels: coal, oil, and natural gas. Combustion of fossil fuels releases pollutants to the atmosphere, where the emissions from all countries combine to cause local, regional, and global issues. One of the primary pollutants of concern is carbon dioxide, a greenhouse gas. Carbon dioxide emissions are responsible for climate change and governments around the world have taken steps to control pollution, but not all countries are successful in reducing carbon emissions.

While all countries produce pollution and emit greenhouse gasses, the emissions are greatly unequal across the globe. Consider what kinds of factors would determine how much energy is used by a country, a region, a household, or an individual. What factors would influence the fuel choices made by these people and institutions?

Conduct research to determine the common fuel sources, emissions, and total energy consumption by the United States and a developing country of your choice, such as China, India, or Brazil.

Â· Support your arguments with documented evidence from credible sources using APA formatting and an APA style reference page.
