Jayadev Kakumanu 8/10/2013 EN 1420 Global warming is caused by carbon dioxide emissions from fossil fuel burning power plants, carbon dioxide emissions from burning gasoline for transportation, methane emissions from animals, agriculture such as rice paddies and from arctic sea beds. It is also caused by deforestation of tropical rain forests, and increase in usage of chemical fertilizers on croplands. This paper will examine the advantages and disadvantages of global warming as well as

A community involves species that interact and live together within the same space and time. The communities present in each given area is a reflection of the physical environment in which they survive. For example, at Kamiak Butte, the climate conditions play a major role in what species are present on each slope. Each slope contains a variety of diverse species living and interacting with one another which will be explored in the remainder of this paper. Ponderosa Pine-Mallow Ninebark-Elk Sedge

example, temperature changes would affect breeding cycle of insect, and this has implications on pollination and food availability for humans. Although short-term weather variations are normal and expected, long-term changes are deleterious to the environment and life on earth (Houghton, 2004). There is evidence that global warming is becoming worse primarily due to rise in carbon dioxide concentration in the atmosphere. In 1950s, the concentration of carbon dioxide was at 315 parts per million. Currently

internationally. There are more than 1,000 networks allocated in 180 countries and it takes up 40 percent market share globally (Company Facts 2011). However, although Ericsson has made the great contribution to the environmental aspect such as enabling a low-carbon economy, reducing environmental impact and facilitate people to communicate around the world (Ericsson: Sustainability and Corporate Responsibility 2011), the company still has been criticized on social human right and any other issues.

warming, however, can be caused by natural effects. One reason is that the earth is constantly going through periods of warming and cooling. Second the two most abundant greenhouse gases water vapor, and carbon dioxide both occur naturally. Third the earth is not the only planet that has had a change in temperature over the past few years, other planets have also had changing temperatures. I belief that global

Some scientist's have been concerned since 1896 about what might happen if there were 5.5 billion tons carbon dioxide in our atmosphere. In 1961 a British scientist did an experiment showing that the carbon in the air was absorbing some of the sun's radiation. Afterward a Swedish scientist, Suante Arrhenius, found out if the radiation of the sun was trapped in the carbon dioxide the temperature of the earth would increase by 1-2 degrees. In 1988 James Hanson, a respected scientist, told the

late, causing businesses to slow down and therefore the economy of the area; increased car ownership and therefore congestion releases a lot of pollutants such as carbon dioxide and sulphur dioxide into the atmosphere. These cause problems such as acid rain when sulphur dioxide combines with water vapour forming sulphuric acid and carbon dioxide is a greenhouse gas so increased levels add to the greenhouse effect and therefore global warming. Increased car ownership also lacks sustainability in terms

Unit 4 1. In the carbon cycle photosynthesis producers convert CO2 into sugars, then during respiration sugars are converted back into co2. After that burial occurs and some carbon can be buried. Furthermore, extraction occurs and human extraction of fossil fuels brings carbon to earth's surface, where it can be combusted. Once that occurs the exchange CO2 in the atmosphere and CO2 dissolved in water are continually exchanged. Finally, combustion converts fossil fuels and plant material into CO2

diffusion between the blood in the alveolar capillaries and the alveoli in the exchange of gases. Alveolar walls are one cell thick embedded by a network of capillaries. High levels of carbon dioxide and low levels of oxygen arrived in the pulmonary artery in the lungs which has travelled from all body tissues. Carbon dioxide diffuses into

Global Warming: Fact of Fiction listed I. Is Scientists to Blame Fossil Fuels for Global Warming II. How the Sun is heating up will affect our planet III. How much Global Warming is Natural Global warming refers to the global average temperature increase that has been observed over the last one hundred years or more. Global warming begins with the greenhouse effect, which is caused by the interaction between Earth's atmosphere and incoming radiation from the sun. Solar radiation passes through
