Global Flooding essays

Global Flooding essays With greenhouse gas emissions and unsustainable human lifestyles raging out of control, there poses the major problem of global warming. Although some people believe this theory to be false, new research may change some minds as to the validity of this phenomenon. Research on Antarcticas glacial movement is raising some eyebrows to whether a warming trend is upon us. If global warming is an actuality, then the human race may face its biggest quandary ever. Global warming would pose many important problems, but the most eminent is not of increased air temperatures, but rather increased oceanic temperatures. Global warming affecting the state of our polar ice caps is a huge concern. Global warming is caused by the emission of greenhouse gasses into the atmosphere. Greenhouse gasses are gasses that increase the ability of our atmosphere to hold in heat. Detailed records of greenhouse gas levels have been analyzed through ice core samples. Inside these core samples, tiny bubbles contain the mixture of gasses that the atmosphere had millions of years ago. Phillip Pan, contributor to The Washington Post, explains that scientists have been able to determine that the levels of carbon dioxide, a major greenhouse gas, have increased by 31 percent from 250 years ago. This data is alarming when you consider the other greenhouse gasses, such as methane and nitrous oxide, which are also accumulating in the atmosphere (Pan). Now that the average global temperature is increasing, this jeopardizes the glaciers that make up the earths polar ice caps. There is a fixed amount of water on the earth. The sea level of the earth is then determined by how much of the water is in a liquid form. This is a delicate balance that must remain somewhat static to keep a persistent sea level. If temperature increases, then this would yield more liquid water and less frozen water. A threat in the polar ice cap in Antarctica has drawn quite a lot o...
