Climate change is one of the most severe environmental challenges facing the world at present. It refers to any change in climate over time, whether due to natural variability or as a result of human activity (Kinyangi et al., 2009). Global warming shows increasing trend and is expected to bring about long term changes in weather conditions (FAO, 2008). Warming of the climate system is unequivocal, and since the 1950s, many of the observed changes are unprecedented over decades to millennia

4,000 years ago a rapid decline in mammoth numbers saw the last mammoths to belong to the small islands found in the Arctic Ocean, north of Siberia.1 Glacial lake sediment holds the evidence to past climatic conditions by radio-carbon dating the fossils and pollen particles preserved in the sediment and silt. Glacial evidence found in a kettle-hole provided a detailed picture of the final years of the mammoth in Western Europe. The sediment gave knowledge to suggest that the full-glacial episode

The way that this essay is written is very much like story-telling, it tells of when and how nuclear plants were shut down and how the goals of fossil fuel reduction were put in place in Germany. This makes this essay much more attention-grabbing and interesting. The way that events are written chronologically in this essay make it much easier to understand. It is an extremely complicated issue, with lots of numbers, so I am thankful that Kunzig used chronological order for this essay. Although there

Hydraulic fracturing, otherwise known as fracking, is a type drilling used for recovering natural gas from underground reserves. Fracking is used worldwide to extract natural gas. Fracking has been becoming huge way to drill in the United States. It is to be said that Fracking is lower cost than open pit mining. The mining companies portray it to be a cleaner method than other ways to recover other sources of energy.these energy sources meet the U.S energy requirements. These could also potentially

To begin with, American Indians had lived in Illinois for thousands of years before Europeans. In 1673, French pioneers, Jacques Marquette and Louis Jolliet, explored the Illinois River.

With all this talk about fossil fuels polluting our earth, I have failed to demonstrate why solar energy is the superior "clean" alternative. Solar energy is a "clean" energy source because it takes the suns energy and converts it to usable energy without any pollution. The article "How Solar Power Works" explains this process. Solar panels contain cells made of silicon under a layer of glass for protection. These cells, when hit by sunlight, generate what they call electron activity. This electron

New Jersey is recognized for getting their energy from coal-fired power plants which in fact, not only pollutes the air that New Jersey residents are breathing in, but the plants pollute the earth’s surface in general by making vegetables and fruits harder to grow in the areas that they are built in. Along with damaging the environment with the meager way that New Jersey gets their energy, the state has not taken much time or energy to fix this specific problem. Power companies in New Jersey have

New Jersey is recognized for getting their energy from coal-fired power plants. However, this does not only pollute the air that New Jersey residents are breathing in, but also pollutes the earth’s surface in general by making vegetables and fruits harder to grow in the areas that they are built in. Along with damaging the environment by the method that New Jersey gets their energy from, the state has not taken much time or energy to fix this specific problem. Power companies in New Jersey have
