Issue 8: Is the Threat of Global Warming Real?

“Climate change is the most important issue of our age, perhaps of any age. If we, individually and collectively, do not act resolutely, extensively, and urgently, the prospects are grim.” -Al Gore, Nobel Peace Prize recipient, 2007 Claiming to be an expert on the data that proves the existence of the threat that global warming poses was made popular by the infamous Al Gore in 2005 with the release of both his book and movie An Inconvenient Truth. By making the theory of global warming more easily accessible and comprehendible to the public, measures to prevent further ozone depletion (specifically O3) have significantly increased. Although recent scientific support has arisen strongly supporting the theory and persuading the public, skeptics claim to have equal amounts of opposing evidence supporting global warming as harmless, natural cycle. The makeup and function of earth’s ozone layer have only been observed less than 100 years. Could global warming amount to a safe pattern practiced frequently by the planet over roughly 4.6 billion years, unaffected by inhabitants of the planet? Though some hold the former proposed question as truth, evidence is strong supporting the idea that marine, freshwater, terrestrial, and high-altitude environments will be gravely affected by human-induced global warming.
“Only the radical rethinking of our relationship with nature can save the earths ecology for future generations.” (Gore) Mayer Hillman is a senior fellow emeritus at the Policy Institute in London and is known for being one of the first proponents of personal carbon rationing as the way for the world’s population to prevent the damage that will be caused from global warming. He is also one of three renowned authors who published The Suicidal Planet, a very informative book embracing global warming as a reality and posing several methods on how one can personally reduce emission of greenhouse gases such as carbon dioxide in their daily life. In The Suicidal Planet, a very commonly proposed statement is addressed: “Why the threat posed by climate change to human welfare and the environment, world-wide, is so grave and immediate.” (Hillman) It is widely believed by experts that within just the next fifty years, there will be more waves, higher temperatures during summers, fewer cold winters, and rising sea levels which will all, as a consequence, lead to loss of life during unusually high heat waves, shrinking of mountain glaciers, a growth in disease, and a great loss of species and their habitats. Rising sea levels are due to expanding warmer water as well as additional water produced when glaciers melt. The increasing concentration of greenhouse gasses are expected to raise sea levels around the world by two to three feet in just this century. Why is the climate changing? The climate is changing due to a natural force known as the “greenhouse effect”, which warms the earth. This effect is caused when humans emit large amounts of carbon dioxide and other gases into the atmosphere. Because the atmosphere breaks down and expels these gases at a much slower rate than they are being emitted, the gases are trapped, leading to a warmer earth. Though carbon dioxide is given most of the blame for global warming, there are five other gases that contribute to the greenhouse effect: methane, nitrous oxide, hydrofluorocarbons, per-fluorocarbons, and sulfur hexafluoride. These gases are released into the atmosphere when human activities such as logging, ranching, and the burning of fossil fuels (coal, oil, natural gas) are performed. The amount of carbon dioxide concentrated in our atmosphere has been increasing since the Industrial Revolution. “In 1750 there were 280 parts per million (ppm) but by 2005 there was 380 ppm, a rise of over one-third.” (Rajan) This increase does not always shock experts. It is a common fact that fossil fuels contain energy

GLOBAL WARMING Global warming, also called climate change, has become a topic of concern over the past decade. Climate has changed drastically over the past decade, “From 2001 through Feb, 2011 the atmospheric carbon dioxide increased by 22.2% of the total increase from 1800 to 2001” (Pangburn). Although I wasn’t completely aware of global warming and it’s circumstances until recently, I can honestly say that it is a issue to be concerned about. Global Warming is an indisputable…

GLOBAL WARMING: NATURAL OR MAN-MADE There is no question that there is an increase in Earth’s temperature and we are experiencing what is referred to as global warming. The Earth has experienced this many times in history on a much larger scale, but, humans did not exist (and would not have been able to exist) at the time. The questions now are whether human actions are accelerating the process of global warming and possibly decreasing Earth’s future sustainability; and, if so, what, if anything…

What Are the Causes of Global Warming? What is global warming? According to NASA Earth Observatory, global warming is the unusually rapid increase in Earth’s average surface temperature over the past century primarily due to the greenhouse gases released as people burn fossil fuels. Global warming is the warming near the earth's surface that results when the earth's atmosphere traps the sun's heat. The earth is getting warmer. The changes are small, so far, but they are expected to grow and speed…

Global warming is the gradual heating of Earth's surface, oceans, and atmosphere. According to the Environmental Protection Agency, “Earth's average temperature has risen by 1.4 degrees Fahrenheit over the past century.” Sadly enough, “temperatures are projected to rise another 2 to 11.5 degrees Fahrenheit over the next 100 years.” As a consequence, global warming has emerged to have one of the biggest environmental issues in the last two decades. For the past years, scientists have been struggling…

Global Warming: Rodriguez Tony P.3 Global warming is caused primarily by carbon dioxide from burning coal, oil and gas. Certain gases that trap heat are building up in Earth's atmosphere. The primary culprit is carbon dioxide, released from burning coal, oil and natural gas in power plants, cars, factories, etc. (and to a lesser extent when forests are cleared). The second is methane, released from rice paddies, both ends of cows, rotting garbage in landfills, mining operations…

endless debate going on about global warming. Some people say that global warming is a threat to us socially, economically, politically, and immediate actions should be taken to minimize it. Whereas, other people say that global warming is beneficial and is a natural process that is required for the sustainability of life on earth. Hence, in my opinion, global warming is a potential threat that causes harm not only to humans, but also to the planet as a whole. Global warming can be defined as the increase…

Global Warming. Is it caused by us? “…Climate change is now with us. It will not go away.”(Musil, 17) Many of us have noticed that our Earth is getting warmer. We seem to ignore what is going on and just continue with our everyday life. There is evidence that our climate has been getting warmer ever year. Some scientist believe it is because of green house gases. Green house gases include the carbon dioxide from gases that our industry produces, methane gases that cows put off, and some believe…
