known as global warming. Global warming refers to the long-term changes in temperature, wind, precipitation, humidity, and other changes in the elements of the Earth's climate (Roebuck, 2003). Natural processes such as solar energy (heat her part), volcanic activity and variations in the Earth's orbit around the sun may be the causes of such fluctuations in the climate balance. However, the changes in climate parameters can affect the change in concentration of certain gases in the atmosphere and to modify

Climate Change: Global warming, Climate Politics and Greenhouse Effect Anna Lena Granderson College Composition 111, F29 Professor Lewis November 21, 2013 Abstract The following sources all support climate change as a worldwide matter that includes global warming, renewable energy sources, carbon dioxide emissions and climate politics. These articles show the link between global warming, natural disasters and also offer viable solutions. Some sources give attention to the greenhouse

“Chemicals in the meat we eat.” What is the event/hazard/issue? Based on what I have read from the article “Natural News” Processed meat has many harmful ingredients and is packaged to be put up and stored for a long period of time. Containing sodium nitrate, the cancer-causing chemical additive that meat companies use as a color fixer to turn their meat products a bright red "fresh-looking" color. Basically every meat there is besides fresh meat includes sodium nitrate unless it says Nitrate free

ocean maintains its salinity because it constantly receives fresh water from parcipitation and river flow. Often times other elements parcipitate out of mineral form and settle to the seafloor. As a result the composition of the seawater does not change. Part 2 Surface currents obtain their energy from the wind blowing over the surface waters. The currents do not exactly follow the wind direction because of an apparent force known as the Coriolis force. Using Figure 12.11 from the text, briefly

The majority of Africans live by subsistence farming and often have access only to marginal land. There is almost no agricultural management and as a result the soils are nutrient deprived at the best of times. Climate change in Africa has significantly disrupted weather patterns with dry spells now lasting longer and rains tending to be more intense. The increased aridity destabilises the soils such that they are easily washed or blown away. This has led to large areas of desertification and the

increases in greenhouse gases are trapping more of the energy radiated from earth and are likely to lead to global warming and weather extremes. The possible impact of human activity on the greenhouse effect was first recognized in the early 1800s. By the turn of this century, calculations were being made relating increases in atmospheric carbon dioxide to temperature change. In the early 1900s it was estimated that doubling or tripling the amount of carbon dioxide in the atmosphere would lead to a

and food shortages and great risk of forest fires. The reason behind these shortages is because due to the change that would happen in the snowpack of Sierra Nevada which is the main source of irrigation for California’s Central Valley which consequently would affect the food/water supply not only for California but the entire United States. Also, a naked Amazon could contribute to a weather cycle of extremely dry air which during the winter months would bring rain to California and the Sierra Nevada

examining the effects of the state of the natural world on human stories, ecocritics like the story of Frankenstein because the bad weather from 1815-1817 helped to inspire the author towards all of the gloom in the novel. Mary Shelley’s Frankenstein was written during one of the most productive periods in the history of English literature, the summer of 1816.
