The Effects of the Melting Polar Ice Caps from Global Warming

The effects of global warming are a serious threat to the world , as fossil fuels continue to be released into the earth ‘s atmosphere the rising temperatures are melting the polar ice caps and as a result the world will be affected if we do not do what we can to help our environment

Global Warming surfaced when scientists noticed the amount of Carbon Dioxide being released into the air , the cause was due to human activity . HYPERLINK “http /www .questia [banner_entry_middle]

. 5 ) Global warming , or The Greenhouse Effect , was first discovered and theorized in 1896 by Svante August . His theory was that was that there was a greenhouse gas being introduced into the atmosphere by the burning of carbon-gassed fossil fuels ‘ HYPERLINK “http /www .questia .com /PM .qst ?a o d (Parsons , 1995 ,

. 5 and that the actual warming itself was good . Scientists were not concerned about the discovery at the time it was discovered

In 1988 the fact that global warming would actually be a danger to the world was introduced by James Hansen , Director of NASA ‘s Goddard Institute of Space Studies . HYPERLINK “http /www .questia .com /PM .qst ?a o d (Parsons , 1995 ,

. 7 ) In an interview with reporter Richard Kerr , a research news writer for Science , Hansen is quoted as saying , I said three things . The first was that I believed the earth was getting warmer and I could say that with 99 confidence . The second was that with a high degree of confidence we could associate the warming and the greenhouse effect . The third was that in our climate model , by the late 1980s and early 1990s there ‘s already a noticeable increase in the frequency of drought HYPERLINK “http /www .questia .com /PM .qst ?a o d (Parsons , 1995 br

The Columbia Encyclopedia defines global warming as , The temperature of the atmosphere near the earth ‘s surface is warmed through a natural process called the Greenhouse Effect . Visible , shortwave light comes from the sun to the earth , passing unimpeded through a blanket of thermal , or greenhouse , gases composed largely of water vapor , carbon dioxide , methane , nitrous oxide , and ozone . Infrared radiation reflects off the planet ‘s surface toward space but does not easily pass through the thermal blanket . Some of it is trapped and reflected downward keeping the planet at an average temperature suitable to life , about 60 degrees Fahrenheit (16 degrees Celsius ‘ HYPERLINK “http /www .questia .com /PM .qst ?a o d 9 “Global Warming Basically , the human race ‘s consumption of fossil fuels is having a negative impact on our atmosphere and if the release of the fossil fuels continues the world will affected

Polar Ice Caps are permanent masses of ice that form in the sea and float around the North Pole Region . They cover approximately 70 of the Artic Ocean and rotate in a clockwise formation that is caused by the easterly currents and winds . These ice caps can be up to 50 meters thick in some areas and it takes approximately 4 years for the ice cap to complete a single rotation (Herbert , 2002 ,

Not everyone believes that Global Warming is true , however there is much evidence supporting this theory . Since 1990 , the world has seen record warming temperatures occurring and these warm record breaking temperatures have been caused by the effects of global warming . The mountain Glaciers are getting smaller and the artic ice pack has become thinner by at least 40 over the past four decades . There is also proof showing that a number of plants and animals have changed their range and behavior in response to the shifts in climate .

The Polar ice caps are melting due to the severe impact of the Greenhouse effect . The increased greenhouse gasses that are being trapped are having a major effect on our environment . Over the past century , the temperature of the atmosphere has risen 1 .1 degrees Fahrenheit . Sea level has risen and the polar ice caps have started melting as a result . HYPERLINK “http /www .questia .com /PM .qst ?a o d 9 “Global Warming ” 2004 If global warming continues , the melting of the polar ice caps will have a serious affect on the environment such as damaging the world ‘s water supply and severe flooding , which many coastal communities will be severely damaged if not destroyed

Some researchers believe that the severity of tropical cyclones will increase due to the rise in temperature of the sea surface . Also with the extreme change in temperatures , some believe that there will be a larger amount of thunderstorms and tornadoes in some area and the frequency of cold waves will become rare in others (Codrington , 2005 br

Global warming will affect the people of the world as well Temperatures will rise to the point that the number of people that die because of heat exhaustion will increase . People with heart problems will be more vulnerable than others . The hotter temperatures will also affect the ozone layer at ground level . The natural ozone layer in the upper part of the atmosphere blocks ultraviolet radiation , however once the effects of global warming take place the human body will be affected , as the ozone will become a harmful pollutant . The ozone will damage the lungs , cause people who have asthma damage and affect others with various lung diseases . Even the more healthy people will experience health problems (ThinkQuest , 2006 ,

According to a study completed by the United Nations in 2005 Global warming will affect the world ‘s food supply . It is estimated that the world will lose approximately 11 of the land available for farming , which will lead to a major reduction in cereal production Also , according to the study , the future of wheat production is in danger as well . Production in the sub-tropics is to be the most affected , in areas like Africa , South Asia , and Latin America (Rome 2005 ,

A UN Conference held in 1997 on climate change , resulted in an international agreement being drafted that will help combat the effects of global warming world wide . The Kyoto Protocol is surrounded by much controversy , as some countries will not agree to comply . HYPERLINK “http /www .questia .com /PM .qst ?a o d 9 “Global Warming ” 2004 The Kyoto Protocol , which was developed in 1997 would require the industrialized nations to reduce their emissions of greenhouse (GH gases by an average of 5 .2 percent below 1990 levels . HYPERLINK “http /www .questia .com /PM .qst ?a o d (Singer , 1999 ,

. 330 Unfortunately some countries will not comply with the Koyto Protocol because of the way it affects their economic structure . George W . Bush stated that the United States would not comply with the protocol because the United States produces about one quarter of the world ‘s greenhouse gases ” HYPERLINK “http /www .questia .com /PM .qst ?a o d 9 “Global Warming ” 2004 ) We are still unsure as to the complete effect of global warming on the earth but the research that has been completed is alarming Personally , I am convinced that the research that has been completed is true and that if something isn ‘t done , the world will be negatively affected . If temperatures continue to increase , the polar ice caps will melt and cause serious damage to coastal cities . There will be an increase in illnesses , which will increase the number of deaths worldwide . Other life forms will be affected by global warming , as some plants and animals will become extinct due to the rise in temperatures The agriculture will be affected because the crops will be depleted in some areas , causing a serious impact on the world ‘s food supply . With the rising sea level , comes property damage that will cause billions of dollars of damage when rivers and shorelines flood , as well as the increasing number of storms world wide

We can all work together to stop global warming because human activity has been proven to be the major cause . Be careful not to over heat your home , make sure your refrigerator is away from heat and defrost it regularly , take shower rather than a bath , turn off the lights when you ‘re not in the room , replace your normal light bulbs with energy saving types , and recycle- buy items in any type of container that is reusable . Other actions you can take is if you can walk , don ‘t drive and if you have to drive – drive the speed limit . HYPERLINK “http /www .questia .com /PM .qst ?a o d “Why YOU Have to 2006 ,
