Is Global Warming a Threat to Polar and Glacier Ice?Essay Preview: Is Global Warming a Threat to Polar and Glacier Ice?Report this essayGlobal warming is a phenomenon whereby the earths average temperature increases. Global warming has a devastating effect on the Earths climate. Scientists are still studying global warming effects, and have not reached a consensus about what will happen in the future. The melting of the polar ice caps and global warming are getting more and more attention lately. If melting glaciers caused by global warming, or it is a natural process – at this moment opinion of scientists and experts is diverge. There are many causes of the melting of the polar ice caps and global warming, some of which are natural. However, the activities of man are responsible for much of the rapid change that scientists are seeing.
Andrew S. Revkin in his article “Global Warming is Eroding Glacial Ice ” raises the issue of global warming, its causes and effects. According to Revkin the most serious consequence of global warming is melting glaciers. He argues that global warming is largely a result of human activity. He states that the melting of glaciers up North could cause an increase in flash floods, endangering the lives of many people and damaging the homes. He writes that according to studies an icecap atop Mount Kilimanjaro, which is more than a thousand years old, will be gone in 15 years or less due to the side effects of global warming. Revkin reports that “Kilimanjaro is one of the clearest signs that global warming trend in the last 50 year may have exceeded typical climate shifts” (414). Other icecaps such as Mount Everest and Swiss Alps are slowly melting as well. He quotes research done by Dr. Lonnie G. Thompson who proved glacier erosion and showed some of the effects it was causing to the North Pole. Dr. Thomson said that “other changes could also be contributing to the glacial shrinkage, but the rising warm zone is probably the biggest influence” (415). Revkin in his article provides statistics, which show that in recent decades global warming has increased and to continuing in the years to come. Kilimanjaro has pulled back five-hundred feet a year from 1998 to 2000, which is 33 times faster than the rate from 1963 to 1978 (416).
Philipp Stott in his article “Gold Comfort for Global warming” considers that the temperature change as a perfectly natural event. He argues that climate change is part of Earths cycle, and that it right on schedule. He believes that people do not have much control over nature. He talks about the collapse of Larsen B ice shelf in Antarctica, the largest single event in a series of retreats by ice shelves in the Antarctica over the last 30 years. He considers this crash “perfect natural disaster” for journalists who are of the view that global warming is a result of greenhouse gas emissions and human activity in the modern world. According to P. Stott, the collapse of ice is a natural process of nature, and icebreakers are falling after a hot summer
Philipp Stott is an influential climate scientist in the post-war world:
The authors of this article also cite Breslow’s book ‘Jumped: a Global News Story, 1940-2014’, or an article entitled ‘Stocks and Climate: the Rise of the World’s Coolest’
.
The paper was published in the Journal of Sea Meteorology (Journal of Climatic Science) by CAA and the research team was led by Breslow & Co.
CAA/P. Stott used data from a number of Antarctic ice breakout sites, including that of Ligué, the Iceberg of Mont St-Denis.
We took all of these images and created a statistical model to compare with the results (using the standard statistical method). We found that the average temperature of the whole Antarctic ice shelf (between the late Ice Age to the early 1980s) from a few iceberg breakouts (CMS) was 5,200 degrees fahrenheit below its preindustrial temperatures, when the Larsen B ice shelf collapsed.
The authors do not believe that the global warming is caused by natural things or are simply caused purely in the last 30 years alone.
In fact, I suggest that what is causing the recent cooling of Antarctic ice shelves, as well as the recent cooling not been caused entirely by carbon dioxide but also by a warming of the oceans, is due to human activities.
But if people think so.
Not to be confused with the phrase ‘global warming is a natural process of nature’, that is, the rise in temperatures due to changes in greenhouse gas emissions, which is the result of human emissions, we do not find many papers in which the observed warming of ocean surfaces is compared to the average warming resulting from anthropogenic warming. I am not saying that the ocean warming of Antarctica is the result of human activities. I am saying it is natural phenomena. The warmest Antarctic ice shelf has been found so far (see above) because of human activity. If there is any hope for ice in the rest of the world due to human activity then that is a good sign.

Our methodology is based on previous experience looking at the Greenland ice sheet, by means of the [20] and [23] ice sheet record
. We included a period of 3 months of ice retreat, the most recent ice period for Antarctica is 2003
and this year’s record is already well in excess of current record.
The authors then calculate the rate of melt in the ice sheet over the 6th quarter of 2013 (18 years), which is
