Polar Ice Caps: Will Chances of Survival Melt Away? If someone was asked to describe the physical condition of the Arctic and Antarctic regions, how would he or she describe them? Would they think of miles of pure, plain ice as far as the eye can see, or would they picture an ever-growing sea of icebergs and saltwater where the miles of ice once were? Though it may be hard to imagine, slowly melting ice in the Polar Regions have the potential to cause hazardous calamities around the world. As the polar ice caps continue to melt, the potential danger that could result grows by astounding margins. Scientists, however, have devised different ways to combat this growing danger and its source. The initial problem is that the polar ice caps are melting, …show more content…
One such outcome would be the possibility of sea levels rising to new heights, or as Denchak (2016) explains, “It’s estimated our oceans will be one to four feet higher, threatening coastal systems and low-lying areas” (para. 10). Another possible negative effect would be a drastic decrease in the earth’s albedo. Scientific experts define albedo as “a measure of how well the earth’s surface reflects sunlight” (Carbon Brief Staff, 2013, para. 3). Additionally, they say that “snow-covered sea ice has a high albedo and reflects 85 [percent] of sunlight. But the open water revealed as ice melts is darker and absorbs more – reflecting just 7 [percent]” (Carbon Brief Staff, 2013, para. 3). This means that as more ice melts, more heat will be absorbed by the ocean, greatly increasing the total temperature of the oceans overtime. Circulation of the oceans’ currents can also be altered from extra seawater added by melting polar ice. Harvey (2015) goes further in detail on the impact of ice on the currents by …show more content…
Whether the polar ice caps and sea ice around the globe are preserved could mean the difference between major changes in the way of living for some organisms, and life or death for others. This issue of melting Arctic and Antarctic ice is overlooked by many politicians, common people, and even some scientists, but if we stand up now and take action to halt the rapidly disappearing ice, humanity may just survive the potential threat and the catastrophes that it can
In his essay, “Global Warming is Eroding Glacial Ice,” Revkin is arguing that global warming is constantly changing the ...
The environment has become a popular topic this year due to our on-going drought. It has always been a serious issue; something Saukko informs us in her sarcastic essay “How to Poison the Earth”. She uses sarcasm and irony in her essay hoping her readers will do the complete opposite of what she is saying because of the stress she puts on the harming chemicals we use every day. We do not appreciate our environment and take it for granted. This ideal is what Ehrlich's essay “Chronicles of Ice” focuses on by using analogies and scientific definitions to describe aspects of glaciers. The melting of the glaciers introduces us to the topic of global warming and how our society is doing nothing to stop it from getting worse. Gawande’s “The Cancer-Cluster
The freshwater from the glaciers would run eventually to the sea, causing sea levels to rise, and also reducing the levels of salt found in the sea. This is in fact disastrous for thermohaline circulation, which carries warm currents to Svalbard from The Gulf Stream, and takes cold water back around to e warmed again. The cold water travels back along the surface of the ocean bed around America, because it has sunk near Svalbard. It sinks due to the levels of salt here. The addition of salt makes the water heavy, dropping to the bottom. When the added glacier water reduces the salt levels, it would, in effect stop thermohaline circulation completely. This would mean that, eventually, warm places would get even warmer, without the cooling sea water, and Svalbard would get even colder, without Gulf Stream water warming the East side of the islands.
It is predicted that the effect of permafrost melting will be that the ocean levels will rise and will significantly increase the temperature and accelerate the rate at which global warming occurs. Permafrost covers 24% of the land in the Northern Hemisphere (Insert Citation), if this was to melt 1700 gigatonnes of methane and carbon dioxide (Insert Citation), powerful heat trapping gases, would be released into the atmosphere increasing the amount of greenhouse gases by 200%.
First, global warming has an immense impact on Arctic Sovereignty as the rise of greenhouse gases thrive in Canada along with other countries. Within 20 years, the polar ice caps of the Arctic have melted twice as fast compared to before. The loss of Arctic ice can furthermore pose a threat to shipping, as navigating the Arctic becomes increasingly challenging. Finally, climate change threatens the extinction of numerous animal species, namely the polar bear. Hence, global warming poses a major challenge to Arctic Sovereignty and Canada along with other members in the Arctic Council must prevent it.
Global warming is amongst the most frightening environmental issues the modern world faces; it’s adverse effects have become significantly more prevalent since the dawn of the 20th century taking the forms of powerful
Canada’s arctic has evidently suffered from substantial climate change, resulting in devastating impacts on all systems in the north. Many climate models indicate that these significant changes will only progress in the future. The monitoring of temperatures in the Arctic have demonstrated that, over roughly the past 50 years, there has been a warming of about 2 to 3°C as of 2009. The average temperature in the arctic has increased almost twice as fast than the rest of the world. In 2020, the projected increase is up to 4°C as well as 8°C by 2050. A numbers of studies have shown that, based on previous climate records, there has been issues of rising sea levels, alterations in sea-ice dynamics, and permafrost degradation. Though there have been multiple strategies posed and adopted, the government of Canada needs to develop an arctic strategy that is more proactive and systemic than previous actions. This strategy needs to be global in its goals for mitigation while still monitoring social, cultural, and economic aspects
(G P Wayne). Though global climate change has the potential of producing some positive outcomes such as the ones mentioned above, it is worth noting that these positives don’t out way the negatives. Our info structure and the systems we have set up would suffer tremendously especially agriculturally, economically, environmentally and even health wise. Here is a deeper look at what scientific research predicts if global climate change continues at the rate at which it is happening today.
How would you like to live in a home that is beginning to fall apart, but only to go on about your day and continue to neglect it until it all comes crashing down? Humans and animals share this beautiful planet that we call home. But this beautiful home of ours is being regularly and increasingly torn apart by our own ignorant actions. These actions of ours have begun to unravel the very world in which we live, causing a self-inflicted crisis known as Global Climate Change. Global Climate Change is a severe dilemma, and it is continuously becoming more evident to the world’s population that climate change is being caused by changes in the reflectivity of earth’s atmosphere and surface, the ever changing variations of energy from the sun reaching the earth, and the daunting increase in greenhouse gasses.
There have been negative biosphere impacts especially in the Arctic because “greenhouse gas concentrations are driving ocean systems towards conditions not seen for millions of years (Shah 5). Conditions such as sea levels are rising which cause polar caps to melt much faster. These polar caps are important to our artic species the thought of having “ice-free summers in the Artic imply loss of an entire biome” (Shah 2). For example, animals like polar bears that have adapted life on top of ice are in danger of extinction. The melting of ice caps and glaciers are causing polar bears to lose their homes. The extinction of one species can spell trouble for other life in the ecosystem. However, polar bears are not the only species in danger.
Although it is often a topic for contention in politics, global warming over the span of several decades, has led to climate change, which has had an alarming impact globally. Climate change needs to ...
The negative side of global warming is that it leads to melting of ice. The world's glaciers, especially Arctic glaciers are melting faster than new snow and ice can supplement them. During the melting of Arctic ice opens over the dark surface of the water or soil and balance change reflects less and absorb a greater amount of heat, therefore, large areas of ice melt rapidly (News, global warming). There is evidence, which will support this argument: scientists from the University of California in San Diego investigated satellite observation data for the Arctic for 1979-2011 years. Since the 1970s, the area covering of the ice has decreased by 40 % and the region has warmed up to 2 degrees (News global warming).It means, that global warming affects to the wildli...
The first part of this essay discusses what the human species has done to deal with the problem of climate change. While some improvements have been made, the problem has not been addressed aggressively enough to stop the damage. What is amazing about this is the denial of so many people that problems exist. If they do realize the risks, they are simply not taking actions to contain the damage.
Polar bears are one of the countless species who are endangered. They were one of the first animals affected by global warming and their population is heavily decreasing. Around 1980, the Arctic was as large as 8 million square kilometres. In 2011, studies show that the Arctic has reduced its size to 4.5 million square kilometers. In the future, will there be anything such as the Arctic? Scientist predict by 2040, only a fringe of ice will remain in Northeast Canada and Northern Greenland. This is known as the Last Ice Area. This matter is mostly taking part in Canada, since; Canada holds more than half the world’s polar bear population. Other affected countries include the U.S. (Alaska), Greenland, Russia, and Norway (the Svalbard archipelago) .There are solutions to slow down global warming but unless we all act together, then there is no hope for the polar bear inhabitants of earth.
... temperatures will drop so low that the “Ice Age” will began. After the polar ice caps melt, we will experience the effect of the frozen freshwater entering into the conveyor belt system that circulates warm water around the Earth and the cold freshwater will dilute the warm salty water and effectively turn off the ecosystem. Then the possible end of days or "Ice Age” will be in affect.
