Through the eyes of most scientists‚ global warming is seen as a very serious and severe threat. The actions taken by humans‚ such as industry and consumption of fossil fuels plus the increase in population and agriculture have played a big part in global warming. If something is not done soon the results could be very bad. By the middle of the twenty first century‚ there is evidence that the Earth will be warmer than it has been at any time in human history‚ and quite possibly since the

caps to melt. This reduces the amount of surface area to reflect the light. In addition‚ as the Earth warms‚ the Arctic tundra releases frozen methane that has been trapped. Methane is a gas that is “fifty times as toxic as carbon dioxide” and therefore‚ creates a feedback loop (Disruption). Methane warms up the Earth which increases the rate that methane is released back into the atmosphere. When CO2 in the atmosphere is absorbs by the ocean‚ decreasing the pH level of the waters‚ this is known

Hydraulic fracking is the method of extracting gas from sediments by injecting the area with a mixture of water‚ sand and other chemicals to release methane gas. Another source of fuel is the mining of coal. Unlike fracking‚ coal mining requires labor that is both physically demanding and hazardous. Mining for coal also requires a larger surface area and therefore could have a larger negative impact on the environment. The burning of coal contributes more CO2 emissions than the burning of natural

When this chemical compound is mixed with water there will be a chemical reaction and it produces acetylene gas. The two anions of carbon‚ the carbide (C4-) and dicarbide (C22-) ions react with water to produce hydrocarbons. The carbide ion gives methane gas‚ and the dicarbide ion gives acetylene gas. This video shows the reaction between calcium carbide and water to produce acetylene and calcium hydroxide. Acetylene is combustible‚ and burns when ignited. Acetylene was discovered in 1836 by Edmund

Biofuels Vehicles that run on biodiesel get thirty percent better fuel economy than gasoline-powered vehicles (Perritano). The many forms of biofuels make it easier to obtain and use. Biofuels are better for the environment because they reduce greenhouse gas emissions. For example‚ ethanol reduces greenhouse gas emissions up to sixty-five percent (Perritano). Biofuels are a source of energy from plants that can help fuel our vehicles and our lives. A biofuel is any fuel that is made from plant

During the inspection‚ the investigators discovered yet another hole in the damaged well. The well was 600 feet deep located next to an aquifer used for drinking water‚ and contaminated supply‚ slated to be distributed to most of the southern state. Methane gasses released into the air are more potent than carbon dioxide. A study of the gasses released into the air found “in 31% of samples‚ silica concentrations exceeded the NIOSH exposure limit by a factor of 10‚ which means that even if workers were

The mechanism for the reaction is called free-radical substitution and involves hemolytic fission of chemical bonds. The reaction proceeds via initiation‚ propagation and termination steps.

Methane concentrations are 17x higher in drinking water wells near fracturing sites than in normal wells. • Contaminated well water is used for drinking water for nearby cities and towns.

Joey Purdee Environmental Hazards Instructor – Kellie Archie July 2‚ 2013 Abstract This week we will be discussing dumps and landfills. We will first describe what is meant by open dumping and also what a landfill is. We will be discussing early to modern landfills and the differences between then and now. We will discuss what some of the problems were with early landfills and also what improvements have been made with newer landfills. Finally‚ we are to choose one the listed landfills and
