Greenland Glaciers and Global Warming Essay Global warming, which is the increasing of the average temperature within the air near the Earths surface and the oceans, has caused the glaciers in Greenland to melt, causing the water levels to rise and the climate to change. Global warming is an unfortunate event that is taking place in numerous parts of the world, enabling bizarre and, in some instances, unnatural changes in the weather. Global warming has become most noticeable in the polar regions, amongst the polar icecaps, or in the more iced-over regions of the world, such as in Greenland and the Atlantic Ocean. In fact, Greenland has become the most common area for quickly-dissolving glaciers, making it the most notorious for climate and weather changes throughout the world. It is difficult to connect weather changes to global warming, though it has been proven that some more pronounced changes are likely to come about, and in fact, already are. One of the most obvious changes involves an increase in precipitation, as well as changes in the average patterns of precipitation, which can lead to flooding and, in turn, drought. The sea levels worldwide will rise, and are rising, as the glaciers melt, which will cause Arctic shrinkage the shrinking of the Arctic region due to climate change. In time, this shrinkage could possibly be seen in other areas, including the Atlantic Ocean. Some other irreversible affects include the frequency and intensity of extreme weather events, such as hurricanes and tsunamis. With the continuously melting Greenland glaciers, these risks are more likely to happen and these changes will only become more obvious and the melting becomes more rapid. Jason Box, a professor at Ohio State and a global warming researcher, has noticed a rapid and unsettling change in the amount of glaciers in Greenland. In an interview in regards to the melting glaciers and global warming, Box stated that we fly over the worlds fastest-deteriorating glacier; and in 2003, we didnt even recognize the place. It had doubled its speed (of shearing off ice) and lost about 6 miles of width (Feran). Box goes on to state the worries that he feels about global warming, as well as pointing out a slight change to weather happenings around the world for instance, a snowstorm in an area that, despite being cold, has never seen such harsh weather. Box feels that this weather event can be linked simultaneously with global warming from the Greenland region. In further studies done by scientists and other global warming researchers, it has been discovered that a huge portion of the Atlantic region is warming just as much and just as fast as the rest of the world (Wilkinson). The scientists have researched and discovered that the temperature has risen 2. 5 degrees in the past half century and that there has been a 140 percent ice loss within a decade. This has caused ice shelves to break up or disappear, exposing the glaciers behind them and speeding up the discharge of ice and fresh water into the ocean (Wilkinson). In the article, Dr. Ian Allison of the Australian Antarctic Division says that the activities taking place in the Atlantic are related to the rising of the air and water temperatures. Allison also stated that the melting of the Greenland glaciers are of the biggest concern, saying that its changes are even more noticeable than those of other regions. In Greenland, the rate of ice loss is getting greater over the last 10 years and the surface ice melt is definitely related to the warming. Allison, whos main focus is that of the Arctic and Atlantic regions, has been keeping close note on the melting glaciers, as well as trying to compare them to changes that have been taking place with weather. The more ice that the Atlantic loses, as well as the rest of the regions under the pressure of global warming, the more heat that comes back to it. When there is no ice to reflect the heat of the sun, the heat permeates through the water, causing the water to warm up even more. The heat is then spread to the remaining glaciers, which causes an almost domino effect, repeating itself until all that can happen is for the sea levels to rise. According to Alan Boyle, a science editor, Greenlands glaciers have been dumping ice into the Atlantic Ocean at a rate thats doubled over the past five years, as researchers have reported. Yet there are many scientists and researchers that are not as worried about the melting of the glaciers as others are; they claim that Greenland has gone through warming before, but the heat had been followed by cooling temperatures. Many of the researchers feel that the same thing is happening again. These scientists are not disregarding the possibility of global warming, but are wary to rule in Greenland as a current problem. Other scientists are against this, saying that Greenland has been warming up 2. 2 times faster than it has in previous years. Greenland is home to one of the worlds largest, and one of the most quickly dissolving, glacier, the Kangerdlugssuaq Glacier. The aforementioned glacier has gone from being completely stationary as of 1996 to flowing at a rate of fourteen kilometers a year by 2005; it is because of this that it is considered one of the fastest moving glaciers on the planet. It is also because of this, as well as Greenlands other quickly-melting glaciers, that will play a huge, unwanted role in the rising of the worlds sea levels (Biello). Greenland has become one of the biggest concerns of scientists, due to the alarming rate that its glaciers are melting, as well as to the obvious increase in the temperature. Since Greenland is home to some of the most quickly melting glaciers, as well as to the worlds largest, it will be one of the main purveyors of climate and weather changes throughout the world. Bizarre changes in weather have already been noticed, with many scientists blaming global warming on these changes. Regardless of the fact that Greenland is in a region of its own, what is taking place with its glaciers can affect the entire world; the weather will be the most pronouncedly changed. Horrific weather events will last longer than what is considered average, and they can take place in areas that would not normally see such conditions. Works Cited Biello, David.
