Global warming, its causes and effects, is one of the most controversial and intensely debated subjects in today’s society. Many scientists on both sides of the argument agree; Earth is definitely going through some rapid climate changes. However, in spite of billions of dollars spent in research, we still have many important questions unanswered. Are these climate changes caused by human-influence or are these changes occurring as part of the Earth’s natural evolution?
For over 4.5 billion-years Earth has experienced many periods’ of climate change. Paleontologists have learned many things about these radical environmental changes by studying fossils and tree rings of plants, rocks, and animals existing over past periods’. These studies revealed many things such as erratic weather patterns, drastic temperature fluctuations, decrease of polar caps, varied sea levels, airborne diseases, and animal extinctions. (Dalrymple)
In fact, during the Jurassic period of the Mesozoic era, over 150 million years ago, Earth’s climate was extr...

...ished in 1988, their combined efforts have created a better understanding of the warming impact on Earth. Unfortunately, even this collaboration is politically driven, and findings remain inconclusive, and argumentative, compared to what our history of natural statistics show.
Perhaps the greatest tragedy of the global warming controversy is, despite billions of dollars spent, we still have no definitive answers. Since there was no influence of industry in many examples of Earth’s previous drastic climate evolutions, we can only conclude at this point, we have little control of the global warming. It just may be as simple as, one day, future creatures will also find our fossils buried under remnants of societies motivated by greed, domination, and over consumption, with an overwhelming need to control nature; never realizing extinction was always their fate.

- I. Christopher Columbus: Christopher Columbus was born in Genoa in 1451. He was inspired by merchants and mariners. As a teenager, he joined the crew of a merchant ship. In his twenties, he settled in Lisbon with his brother, making maps for a living. Later on, he married a woman whose father had connections with the captains on Henry the Navigator’s ship. The couple settled in Madeira as Columbus visited multiple trading posts on the west coast of Africa. During his sailing trips, Columbus read some books that stimulated his curiosity, such as Natural History, written by Pliny.... [tags: Christopher Columbus, Expeditions, Discovery]

- On April 25, 1975 a Newsweek headline blamed a deadly outbreak of southern tornadoes on a disastrous average climate temperature decline that had been persisting for over thirty years. This report stated that the temperature drop increased pressure points in the upper atmosphere amidst the circumvential flow of the westerly winds that in turn affected temperate regions to increase numbers of deathly droughts, floods, freezes, and late-coming monsoons (Gwynne). Global cooling was a scare that resulted because of a theory, but now the concern is global warming.... [tags: Global Warming Essay]

- The planet earth is in serious jeopardy due to global warming. The polar ice caps are melting at an astonishing rate. Severe flooding and droughts are creating havoc around the world. All nations must begin to address, formulate, and implement the necessary solutions to reduce global warming before it becomes irreversible. Developed countries can drastically reduce the emission of green house gasses (GHG) which are destroying the ozone layer by reducing the destruction of rainforests, switching from electric generating power plants that are burning fossil fuels, to electricity generated by wind technology, and reducing the amount of carbon dioxide (CO2) emissions from vehicles....

- The Uplifting Tale of Today Will Be a Quiet Day Some readers see death, but when I read the story "Today Will Be a Quiet Day" by Amy Hempel, I find it to be a light hearted, first-hand account of people coping with transition. Even its location in the table of contents under the heading "Childhood and Adolescent" (Barnet), implies that the story is not about death at all. A newly defined family, one man, a boy and a girl, is faced with the aftermath of divorce and explore among themselves the intricacies of life.... [tags: Today Will Be a Quiet Day Essays]

- Brown: The Last Discovery of America completes Richard Rodriguez's three-volume work in which he explains and explores the ethnic and racial future of America. In this particular book, the author defines the color brown not as the representation of the Hispanic race but as the color of the future. Black, white, yellow, the author explains, are incorrect racial categories for it is not how nature works. Nature yearns for combination of all different colors, and brown is the final result. In the chapter "Hispanics," as seen through imagery, personification, and humor, Richard Rodriguez upsets the reader to show that racial categorization is unfit and that racial barriers are meant to be broken...

- Introduction From man’s basic understanding of existence, he acknowledges that his presence is but a fraction in time in relation to the longevity of the Earth’s existence. This attests to the time period in which the Earth functions. Man’s calculations of year to year changes in the Earth’s atmosphere are meager at best in determining the cycle for such an entity. Man’s oldest data dating back from ice core samples from Antarctica can not trace back further than a minute percent of the history of the billions of years that the Earth has existed....

- Introduction: The purpose of this paper is to investigate whether global warming could affect the thermohaline circulation cycle (THC) significantly enough that it could even shut it down and thus cause a shift in the climate of Europe severe enough to cause another Little Ice Age. To answer the question about whether global warming could cause another ice age, I have divided this paper into segments. The first will explain what the thermohaline circulation cycle is. Next, I will look at the last interglacial period and observe what the conditions were like especially in respect to the THC.... [tags: Science Global Warming Climate Change]

- Global Warming For the last 20 years or so the subject of global warming has spawned heated debate among the world’s brightest minds. Its causes and effects, if either actually exists, have been hotly debated. The most popular hypothesis is called the greenhouse effect with the agreed upon cause being green house gasses. These gasses are all naturally occurring and include water vapor, methane, oxygen, and the now infamous carbon dioxide. Greenhouse gasses exist in the atmosphere and have an effect on our global weather.... [tags: Environment Global Warming Climate Change]

- Global Warming 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. (Melissa Phillips). This results in an increased emission of greenhouse gases. (Caroline Quatman). Short-wave solar radiation sinks into the Earth's atmosphere and warms its surface; while longwave infrared radiation emitted by earth's surface is absorbed, and then re-emitted by trace gases. (Brent C. Willhoite) Climate changes occur in our earth's atmosphere due to a buildup of greenhouse gases.... [tags: Environment Global Warming Climate Change]

- “If Christopher Columbus Returned to the ‘New World’ in the year 2000, what evidence of his discovery would he find?” Christopher Columbus set sail August 3, 1492 in search for a new route to the West Indies. Sailing west from the Canaries, his ship was tossed around by trade winds, which ultimately guided his fleet off course. Due to his new route, Columbus came across land, which we know today as America. When Columbus arrived to the New World, he thought he had reached his required destination, the West Indies....
