Global Warming: Are Humans to Blame?
An English major with a minor in Meteorology, I have a huge passion in learning about the weather. I love doing research on all aspects of the weather, but one topic has remained controversial for years and that is the cause of global warming. I decided to do some research on the issue in hopes of coming up with some type of conclusion based on the facts that I am able to find. The question always arises as to whether humans are to blame for our current global warming. Do humans in fact pose a threat to the global warming crisis and are they to blame for the slow increase in temperature of the earths atmosphere? Before one can begin to argue the facts whether or not humans have an influence in the condition of our atmosphere, one must first learn exactly what global warming is.
To begin a discussion about what global warming entails, I must first explain the greenhouse effect. When solar radiation enters the earth’s atmosphere some of the energy is absorbed by the earth, while the rest is refracted back into space. During this process, when radiation emits from the surface back into the atmosphere, greenhouse gases such as water vapor, Carbon Dioxide (CO2), and Methane trap some of the radiating heat in our atmosphere and cause the surface of the earth to warm up. This is a natural process that has occurred on earth even before the existence of humans, and still naturally occurs today. Moreover, clouds, or large masses of water vapor, are natural absorbers and refractors of energy. Although they reflect more solar energy than they absorb, they still help to maintain a warm and tolerable planet for all living kind, thus clouds play a big part in the warmin...

The past few years, I’ve taken an interest into our constitution. As a result of this interest, I would at times sift through interesting Supreme Court cases. Tinker v. Des Moines and Johnson v. Texas would, to some, conflict with cases like Schenck v. United States. The line drawn on the issue of free speech to others may be blurry, but to me, it has always been crystal clear. So when Super PACs, Political Action Committees that can donate unlimited funds to an independent cause, arose, I concurred with the Supreme Court’s decision to protect free speech. To most it seems, Super PACs are just evil PACs, and they, unlike regular PACs, ruin elections. They really only differ by their method, however, when discussing the movement of money. Super PACs are run “independently”, and PACs are usually partisan.
Speechnow.org v. FEC brings out a few significant keys. First, the freedom of speech and the right to privacy are the regarded as high standing rulings in America. Those things have the ability to be corrupted, but, ultimately, the court’s will leave it is up to the citizens of the United States to make those decisions for themselves. Also, another significant factor is campaign finance is an ever-changing topic that has loopholes that need to be addressed on a case-to-case basis.
First, during the last few decades the Earth is experiencing greater rate of rising temperatures due to greenhouse gases that are being produced by human activities rather than because of environmental reasons, such as solar or volcanic activities. In 2006 the President of the National Academy of Sciences stated: “There is no doubt that the Earth is warming,” also he added that people are at least partly responsible for these changes in addition to regular factors (Cicerone, par.4). Natural factors have produced climate fluctuations on Earth for several million years. People have effected an atmosphere of the Earth just for nearly one hundred years, since Industrial Revolution has begun (Revkin 340). Of course, it is unfair to say that global warming is caused entirely by humans. For example, people can not have an impact on the position of Earth in relation to the sun, or on the galactic density, or such nature events as air emissions of volcanic gases. As a result of these environmental factors, Earth usually had higher rates of temperature fluctuations during the previous million years than it has in later centuries. On the other hand, people are responsible for the highest concentration of greenhouse gases during the last 650,000 years in the atmosphere due to industrial manufacturing, driven by the increase in consumer consumption (Lindsey, par.
Global warming is a scientific, political, and controversial topic. Some believe it is catastrophic, a slow moving killer hiding in the shadows. Others do not even think twice about it as they race by in a Hummer. Global warming is the gradual increase of temperature throughout different climates. It is caused by the greenhouse gas effect in which greenhouse gases, like methane and carbon dioxide, reflect sunlight back and forth. This reflected ultraviolet light bounces between the earth and the ozone layer and becomes trapped, resulting in a gradual rise of temperature. Over time, the slow rise of temperature causes new climates throughout the globe. The article “What Megablazes Tell Us About the Fiery Future of Climate Change” by Tim Dickinson
The current issues about legalizing Cannabis in California are, if California legalizes Cannabis it still does not mean that federally it is legal. Since Colorado and Washington have legalized Cannabis the owners of the dispensaries are not protected like other businesses. Such as when time comes to transport money to banks the owners of the dispensaries have to us...
Think about a time when your car was parked on the side of the street all day long. Then you decide to run to the store and get some things for dinner. The minute you opened the car door, you feel the currents of hot air blowing past you, and when you sit down, you feel as if your car is radiating heat! This is a tiny, yet real example of the process called the greenhouse effect. This effect includes a form of matter, absorbing heat or radiation from the sun. What happened in the car was the glass assists the absorption of the heat and trapped the heat inside, containing it. Equally, the earth's atmosphere contains gases called greenhouse gases such as Carbon Dioxide, Methane, and water vapor, which absorbs the rays we receive from the sun, and trap the heat inside. Our atmosphere, which contains the greenhouse gases acts like a blanket; absorbing the heat from the sun, and preventing it from going away from the earth's surface. The more the heat gets trapped because of the increase in greenhouse gases, the more the temperature rises, causing global warming. Global warming is “an increase in the earth's atmospheric and oceanic temperatures widely predicted to occur due to an increase in the greenhouse effect resulting especially from pollution,” (Merriam Webster Dictionary). The two main causes of global warming are the greenhouse effect and solar variations. The Greenhouse Effect “refers to the process by which absorption and emission of infrared radiation atmosphere gases (mainly Greenhouse gases such as CO, NO, and Carbon Monoxide) warms the Earth’s atmosphere and surface,” (Merriam Webster Dictionary).Solar Variations are “changes in the amount of radiant energy emitted by the Sun,” (Wikipedia).
Physical activities that keeps your heart rate elevated for a consecutive period of time is known as cardiovascular exercise. This type of exercise promotes heart, lung, and vascular health, and also burns calories, which is essential if you desire to lose those extra pounds you've gained over the holidays. (See References 3) The Centers for Disease Control and Prevention suggests doing moderately-intense cardio, at least 150 minutes a week. (See References 4) Rather than doing cardio that you dislike, build your workout around exercises that you enjoy. Da...
Proposition 64 was recently passed in California making recreational marijuana use legal. California has been among the few states that have taken this step towards accepting marijuana so far. Recreational marijuana use was not commonly accepted and was looked down upon until doctors found medical benefits in marijuana and proved it was not as harmful as the majority thought previously. The battle between whether this drug is harmful or helpful is still relevant today. Over the years, the population’s support for the legalization of marijuana has increased. Although the court case Gonzales v. Raich shows lack of support for the advancement of marijuana on the federal level, other state cases such as California Proposition 215, which allows
The greenhouse effect is a natural process that keeps the earth at temperatures that are livable. Energy from the sun warms the earth when its heat rays are absorbed by greenhouse gasses and become trapped in the atmosphere. Some of the most common greenhouse gasses are water vapor, carbon dioxide, and methane. If there were no greenhouse gasses, very few rays would be absorbed and the earth would be extremely cold. When too many rays are absorbed the earth’s atmosphere heats up and it causes what we know as global warming. Al Gore (2006) described the greenhouse effect as the potentially most dangerous environmental problem facing mankind, with consequences second only to nuclear war (p.299). As the name suggests, global warming isn’t merely affecting parts of the world, it is threatening the world globally.
Global warming and global climate change is the study of future increases of temperature across the globe. Studying climate change refers to how the over- all climate will change such as the dry places getting dryer and the wet places getting wetter. Global climate is dependent on “the greenhouse effect a natural process that helps regulate temperature” (Easterling and Karl). In the past few centuries humans have had a monumental effect on increasing of greenhouse gases in the atmosphere. Climate change is result of the increase amount of the greenhouse gasses in the atmosphere such as methane, carbon dioxide, water vapor, nitrous oxide, and ozone. “Global temperature has rose approximately 1.4 degrees Fahrenheit over
California has always been on the progressive side when it comes to legislation involving popular issues. It has been a major player in the legislation surrounding notorious issues, one of which being the legalization of marijuana. The issue of medical marijuana in California has always been one of controversy and controversy is usually stemmed from confusion. The best way for the controversy surrounding California's medical marijuana policy to be cleared up is to clear up the confusion by defining the policy exactly by examining the past, present, and future of medical marijuana in California legislation.
In talking about global warming, we need to learn what causes the greenhouse effect. Rays from the sun are taken up and absorbed by water vapor that is natural in the atmosphere. The United States emits the largest man made greenhouse gases in the world. As Americans we must realize the responsibility to reduce the emissions. (Gore, Albert) Water Vapor is eighty percent of greenhouse warming. The last twenty percent results from other gases that are in very little amounts. A huge absorber of the sun’s heat rays is carbon dioxide. Us as humans release a lot of carbon dioxide. When fossil fuels are burned, they release big amounts of carbon dioxide. Carbon dioxide is on the increase in our atmosphere due to car emissions. Approximately eighty percent of CO2 increases because of man’s use of fossil fuels. When there is more carbon dioxide in our atmosphere the more sun rays are absorbed. In result to this happening this will cause the earth and the earths atmosphere to warm. When the earth is warming, water temperatures will start to get warmer. Oceans and lakes will get warmer in result f...
Gastroenteritis, sometimes referred to as infectious diarrhoea is a common disease that affects millions of people annually. It is a disease caused by viruses, bacteria or parasites that enter the human body and spread, which induce symptoms such as vomiting, diarrhoea, abdominal pain and nausea. Although it is a common occurrence in society and is usually not harmful, cases of gastroenteritis in less developed countries may have more fatal repercussions due to their inability to access ample means of treatment. Over time, as more research was conducted into the disease, scientific developments were made to aid those affected by gastroenteritis and reduce the number of fatalities by educating people regarding preventative methods.
With any accident investigation one of the main focuses is to determine the cause and factors involved in the accident. Determining the cause of the accident would consist of finding out why the accident happened (NTSB, 2010). This can include any mechanical failures to environmental issue or even human error can be a serious cause to an aircraft accidents. All facts, conditions, and circumstances are taken into account when determining the probably cause in an investigation (NTSB, 2010).
Global warming is an increase in the earth's temperature due to fossil fuels, industry, and agricultural processes caused by human, natural, and other gas emissions. This results in an increased evacuation of greenhouse gases. “Short-wave solar radiation sinks into the Earth's atmosphere and warms its surface while long-wave infrared radiation emitted by earth's surface is absorbed, and then re-emitted by trace gases.” (2)
