No one in the scientific community would argue with the premise that the earth’s climate has changed over the eons of its existence or that it will continue to change. The arguments now revolve around if mankind’s use of the environment has specifically altered our climate.

Scientists have described our world as a clump of matter that spun out of the sun to join its journey hurling though cold and empty space. Our spaceship earth would match the moon and have no climate had not molten core continued to pierce its cold crust, spewing forth chemicals that would eventually form our atmosphere, our seas and life itself (“Mcphee”).

The geological record shows a tumultuous earth, but because the events occur slowly over millions of years, we, as humans, tend to regard our world as static. During the Cambrian period, the seas level rose “at a rate of ten miles ever million years” (McPhee 186). With the world having a finite amount of water and no ice age occurring 544 million to 490 million years age, the rise of water can only be attributed to the heat of the mantel pushing the bottom of the seabed up. Over half of North America was submerge from this rise of the oceans (“McPhee”). The seas raised an average of five and a half feet every 100 years.

Today, we, as a species, may be facing similar dilemma of rising seas caused not by a bulging mantel, but by melting glaciers. New evidence shows that the ice at the fringes of Antarctica is melting; allowing larger ice sheets to flow into the ocean faster and inexorably melt. The weakening of the fringe ice shelves that are attached to the shore or the seabed has opened the door for the vast inland ice sheets to melt. Some of the same kind of shifts has been reported in some g...

Essay on We Must Stop Global Warming

- Why Humanity Needs to Make a Serious Effort to Stop Global Warming Climate change is a proven reality that threatens our planet. It is caused by an increase of the greenhouse effect, a process that keeps our earth warm by having greenhouse gases trap the sun’s heat and re-emit it. While the greenhouse effect is important for life to exist, it can also be harmful to life if the concentration of these greenhouse gases increases too quickly. Humans are causing the concentration of greenhouse gases in the atmosphere to increase substantially....   [tags: Global warming, Climate change, Ocean]

Is Global Warming A Problem? Essay

- Is global warming a problem and if so, what can we do about it. Many researchers, scientists, and environmentalists are expressing concerns about changes in the overall climate of the earth. Some believe that a dramatically dangerous warming is taking place in the overall global climate, a problem that is referred to as "global warming." Changes in climate can result from both natural events and human activities. Examples of natural causes of climate change are volcanic eruptions, variations in the earth 's orbit around the sun, and variations in solar output....   [tags: Global warming, Climate change, Greenhouse gas]

Global Warming And Global Warning By Bjorn Lomborg Essay

- The book I chose to read for this book report was Cool It: The Skeptical Environmentalist’s Guide to Global Warning by Bjorn Lomborg. This book was originally published in 2007. Lomborg offered many perspectives on the subject of global warming and climate change, stating that it will cost millions and billions of dollars. However, even with the amount of work and money put into stopping the global warming problem, there may be little impact on the world. Lomborg argues that perhaps humans should start with smaller steps, such as fighting diseases or maintaining a safe, fresh water supply....   [tags: Global warming, Climate change, Bjørn Lomborg]

Global Warming Position Paper

- During the Earth’s existence, there have been shifts in weather that seem near unexplainable. Without documentation of these events, there is no way of knowing exactly what caused these strange shifts in weather or to what extent. So many people see the ice caps melting and automatically blame pollution and the negligence of people. While it is true that most people do not take care of the environment and have little respect for it, is it possible that the negligence is just a factor and not the driving force....   [tags: Pollution, History fo the Earth, Global Warming]

Global Warming Is An Important Ecological Issue Essay

- Global warming is an important ecological issue and has many negative effects upon our environment. Global warming, or what other calls it, the Greenhouse effect, is the result of a natural process. This ecological process keeps our planet warm enough to provide life, but because of the increase of temperature, caused by the high accumulation of gasses, our recent way of life and environment could be in danger. Over the years the Earth’s temperature has been increasing as a consequence of industry, fossil fuels, and agricultural processes produced by gas emotions, human and natural actions....   [tags: Global warming, Weather, Climate change, Earth]

The Effects Of Global Warming On Plants And Wildlife Essay

- Scientists have established that if we do nothing to cut greenhouse-gas emissions up to the year 2100, the planet’s sea level will rise 14-32 feet. Global warming has been a growing problem in daily life for people around the globe. From rising temperatures to rising sea levels, anyone can attest to the effects of global warming every day. Leader’s choices are huge factors on this change and will be for years to come.
