GLOBAL WARMING AWARENESS

Global Warming Skeptics - Skeptics of global warming think that global warming is not an ecological trouble.
Global Warming Facts - 8 Facts about Global Warming
Causes of Global Warming - The Green house gases are the main culprits of the global warming. The green house gases like carbon dioxide, methane, and nitrous oxide are playing hazards in the present times.
Green House Gasses are the ingredients of the atmosphere that add to the greenhouse effect.
Al Gore Global Warming Initiative - Gore has written a book that archives his advice that Earth is dashing toward an immensely warmer future.


Currently nearly 435 million gallons of gasoline is burned each day by Americans, remember, this is just in the United States. Gasoline for your car isn’t the only thing that petroleum is used for, it can also be use for plastic creation and other medical uses. When petroleum is gone, a lot of the products that we have grown to rely on, will also be gone. The problem with using petroleum freely is that as we use the “easy petroleum” sources, we eat up the reserves and then we must turn to harder to extract sources, and that has environmental issues attached.

One thing that a lot of people forget is that we have polluted the earth even before we place gasoline in out gas tank. This is because when you extract gasoline from petroleum, it takes energy, and that energy isn’t exactly from the cleanest sources.

A study by Argonne National Lab estimates that every gallon of gasoline you buy already has put five and a half pounds of carbon dioxide into the atmosphere before you use it in your vehicle. Analysts call these emissions “upstream” or “well-to-pump” emissions, and they account for roughly 20 percent of the greenhouse gases emitted from gasoline. (The remaining 80 percent occurs when gasoline is burned in a car engine.)

Petroleum from Unconventional Sources
Unfortunately, the drive to extract petroleum from unconventional sources means that upstream emissions may get worse in the future. Some of these new sources are “unconventional” sources, such as tar sands. a mixture of sand, clay and bitumen (a heavy, sticky oil). Unlike conventional crude that is pumped from the ground as a liquid as you would expect from an oil derrick, or from oil fields around the world, tar sands are solid and cannot be extracted through traditional oil drilling methods. Instead, tar sands are removed either through the environmentally un-friendly method of strip-mining or by a process that uses steam to heat the tar sands in the ground until the bitumen separates and rises to the surface. Both processes are energy-intensive, as is the refining of bitumen into a version of crude oil that then can be refined into gasoline. No matter which method is used, it wont be clean and it will harm the environment.

The tar sands extraction process has serious environmental consequences in the local areas where it is conducted, such as northern Canada. But perhaps more serious is the global environmental consequences of shifting to unconventional oil supplies such as tar sands. UC Berkeley researchers recently estimated that tar sands and extra-heavy oil were estimated to have upstream greenhouse gas emissions that were between 1.7 and 2.9 times higher than those of conventional crude oil. Producing oil from other non-traditional sources, such as coal or oil shale, leads to even greater increases in greenhouse emissions.

At the moment, most of the gasoline we consume is made from conventional petroleum. However, some experts project that within 10 years, more than a third of the world’s oil could be derived from unconventional sources like Canada’s tar sands. If this occurs, the upstream impact of a gallon of gasoline will worsen. Sorry—there’s no silver lining in this dark and ominous cloud.

Global Warming Skeptics - What are they saying?
Global Warming Facts - How does it affect you?
The green house gases like carbon dioxide, methane, and nitrous oxide are playing hazards in the present times. These green house gases trap heat in earth’s atmosphere and thus result in increasing the temperature of earth. The excessive emission of these gases is one of the major Causes of Global Warming. The major source of carbon dioxide is the power plants. These power plants emit large amounts of carbon dioxide produced from burning of fossil fuels for the purpose of electricity generation.


There has been a considerable increase in the average temperature of earth in the past century. This rise in temperature is attributed to the effects of global warming brought about by the accumulation of greenhouse gases in the atmosphere. This phenomenon is called Global Warming. The effects of global warming are numerous. The main culprits in the issue are excessive discharge of green house gases in the atmosphere.
