Global warming has been discussed over and over again. In recent months even politicians like Al Gore have gotten involved. He created a documentary called, “An Inconvenient Truth”, to try and push for more action as well as to enlighten the public. His view is that there are solid facts that global warming exists and skeptic scientists don’t. Many people believe that global warming does not exist because they are not being affected directly; however, scientists believe that the increase in natural disasters comes from global warming.
In NY, I hear a few people here and there saying, “you call this global warming” just because the temperature is at 10 degrees even though this winter it only snowed once compared to the past. Have you ever seen the painting of George Washington sailing across the Delaware River? If you have, you know there is ice in that water. Now if you look at that river during the time of year that picture was taken, there is no ice. What about in the summer when you feel the heat of the sun and realize it is a little hotter now then a few years ago? That could all be in your mind due to media hype and all, but how can you tell?
Where does all this global warming stem from anyway? Who or what is the cause of all this debate and discussion? Some People are afraid and they want answers to their questions. The following is the list of the top 10 causes of global warming. With all the facts laid out, one can make a better decision about what global warming is and how it might affect them.
1. Carbon Dioxide From power Plants
One of the largest contributors to global warming is said to be pollution from power plants. Every time you turn on a light, you add to the tons of carbon spewed into the sky by long tubes connected to these massive coal or oil driven “machines”. According to recent studies, approximately 40% of all carbon dioxide emissions comes form power plants. Natural gas, coal, and oil are the 3 types of polluting power plants. Coal is the biggest contributor out of the 3 because of it releases more carbon than the rest of them per capita. Studies, like the one done in the film, “An Inconvenient Truth”, show that the levels of carbon in the atmosphere has increased drastically in recent years and will probably continue to increase in the years to come.
Some skeptics believe that the levels of carbon are completely normal. According to http://www.geocraft.com, the levels of carbon found in the atmosphere today mirror those found hundreds of thousands of years ago. They believe the scientific “proof” that global warming exists is taken out of cortexes because they look at the past 100 years instead of the bigger picture. The earth has been around of billions of years; earthquakes, monsoons, ice ages, meteors, and so forth, have all affected the earth without destroying every living thing on it.
Despite what others say, many people have created solutions for the pollution caused by power plants. For example, products that help to reduce the green house emissions have emerged. Filters that improve the quality of the air released into the atmosphere have been created to solve this problem. In addition, government regulations have been placed to force owners of large industrial buildings to improve the quality of the air produced by their buildings. Finally, hydrogen power has also become a way of reducing carbon. According to Tom Simonite of http://www.newscientisttech.com, using carbon is better than using water to generate power, and it is completely environmentally friendly.
2. Pollution Emitted from Cars
Driving to work in the morning is one example of this. When your stuck in traffic, how long does your car stay idle on the road, releasing it’s pollution into the air? There are approximately, 3 billion vehicles being used today. Similarly with the power plants, cars also emit carbon into the air. Cars emit millions of tons of pollutants into the air. In some dense cities, this causes some of the smog and ozone problems. 1,500 cases of cancer are reported each year from pollution according to http://www.nsc.org.
Luckily, solutions are available. Many ask, “What can I do.” One thing that can be done is a switch to more environmentally friendly vehicles such as hybrid or electric cars. Some countries are even using cars that run on hydrogen. In the near future, talk about ethanol to replace gasoline in cars seems to be a promising change.
3. Pollution from Trucks
Trucks, although less in volume, make up for a large portion of the earth’s pollution with each truck’s individual output of pollutants. The difference between cars and trucks is the type of fuel used to run them. Diesel, the standard for trucks and other vehicles used for carrying large loads, is known to be less clean than gasoline. Trucks roaring down streets can bee seen from a mile away with a tiny smoke stack blowing out the product of having to carry large amounts of goods from one place to the other.
How can our society get rid of trucks? They are vital for the economic health of certain companies. They are used to build homes and carry supplies, People go camping and carry gear with them, and the list goes on. According to http://www.ucsusa.org, diesel is reaching a point where it can no longer meet the standards of government regulations. What kind of alternative can be used instead?
