within habitable temperatures. Because the moon does not have greenhouse gases. Earth’s greenhouse gas is made up of several components. Water vapor‚ carbon dioxide‚ and ozone are the dominant stabilizing greenhouse gases. Levels of carbon dioxide‚ methane‚ and nitrous oxide have increased substantially over the last century. Carbon dioxide is the most important of these three‚ and it is higher than it has ever been over the last 650‚000 years. More carbon dioxide in the atmosphere leads to an increase

billions of tons of methane gas and carbon dioxide a year. MIT students researched and recorded that the methane levels in the atmosphere have increased more than in the past ten years. Casey Kazan wrote an article about the MIT scientists’ study and said “ Since all worldwide levels rose simultaneously throughout the same year‚ however‚ it is probable that this may be part of a natural cycle - and not the direct result of man’s contributions.” (Kazan‚ 2009). With the increase of methane levels‚ MIT scientists

The causes of global warming are broadly divided into two categories - natural causes and anthropogenic (man-made) causes. Natural Causes Natural causes of global warming include the release of methane gas from arctic tundra and wetlands‚ climate change‚ volcanoes etc. Methane‚ a greenhouse gas which traps the heat within the earth’s atmosphere‚ is let out in large quantities in the arctic tundra and wetlands. In case of volcanoes‚ when a volcano erupts‚ tons of ash is let out into the atmosphere

Advantages of Biomass energy. People says that biomass energy do not have any different than other energy. Biomass energy just have the same amount of carbon dioxide‚ methane released. The most famous debate is about food and biomass energy. Large areas of crop and farm land are used for growing biomass. This cultivation of crops for fuel might just put a little to much strain on our limited resources such as water and land which could be used for food crops. This biomass energy also just not economical

rising levels of greenhouse gases” (Conway). According the United States Environmental Protection Agency‚ “Gases that trap heat in the atmosphere are called greenhouse gases.” Greenhouse gases are broken down into four categories: carbon dioxide‚ methane‚ nitrous oxide‚ and fluorinated gases. Each category will be later looked at in further depth along with the three main factors each gas has on climate change. Changes in sea level‚ animal species extinction‚ and weather patterns are just several

Anaerobic Digester Considerations for Swine Farms in North Carolina Collecting biogas from anaerobic digestion of swine manure can benefit the environment by reducing methane emissions (has potential value for equivalent carbon credits or greenhouse gas (GHG) credits)‚ and by providing energy‚ as biogas is about 60 to 70 percent methane. Methane has an energy value of about 1‚000 BTU/SCF1‚ so biogas can have an energy value of about 600 BTU/SCF. Plug-flow or complete-mix anaerobic digesters using metal

A social constructivist approach is relevant in understanding how knowledge and debates are formulated by differing social groups. Using this theoretical framework provides us with a background on how a technology‚ in this case hydraulic fracturing‚ is constructed through separate discourses. According to Bijker‚ “In the social construction of technology approach (SCOT)‚ relevant social groups are the starting point. Technical artifacts are described through the eyes of the members of these groups
