Antarctica Ice Essay

The Arctic Sea Ice is melting or slowly disappearing and it is said to be one of the reasons of global warming. What is happens is that the Arctic Ice it melts a little and gets smaller during the summer season and than during the winter season the ice gets bigger and expands over the Arctic Ocean, “a freeze-thaw cycle that in the Arctic has been dramatically altered by global warming (Global Warming Effects).” The Arctic Sea Ice in the past could grow up to 3 meters, which is around 10 feet, but now the average thick ness is becoming much less, and some scientist are afraid that in a few decades there might not be any sea ice during the summer (Global Warming Effects). Another major thing that has been discovered is that the amount of ice

The study noted that while Antarctica has already begun to melt, the ice sheet’s future mass balance is unknown due to a combination of factors: future emissions of greenhouse gases; atmospheric warming; and oceanic warming that results from atmospheric warming.

Antarctica is the coldest, driest, and most inhospitable continent on Earth. Yet it is yields some 90 percent of the Earth most precious natural resource: water. But behind this pristine exterior, Antarctica is fighting a losing battle. New data suggests that the continent as a whole is warming at an alarming rate. According to recent studies gathered from Nature Magazine, the western half of the continent is warming five times faster than any other place

In Greenland and in the Arctic I was astonished to see that ancient glaciers are rapidly disappearing well ahead of scientific predictions. All that I have seen and learned on this journey has terrified me. For decades, scientists have struggled to get the same basic message across: global

At the present rate of global warming most of the frozen portions of the Arctic may disappear by the end of this century.

For many years now, scientists have believed that our climate is changing. This climate change has caused water currents up north, near Antarctica to shift leading to warm waters taking the place of the usual cold arctic waters. Warm water melts the glaciers and causes the top of the glaciers to float off into the sea, allowing the warm water to melt even more glaciers. The extra glacier melting into our sea has caused the sea levels to raise and the

In recent months, scientists have been taking notice to record cool temperatures observed in the North Atlantic Ocean, while the rest of the world is experiencing record warmth. They believe this cooling of the water to be due to the accelerated melting of the Greenland ice

Economic growth is vital to sustain human life; however, the unsustainable consumption of natural resources to attain this demand is leading to self-destruction. The Earth is facing environmental changes, including climate changes, which are altering the Earth system. Significantly higher thermal expansion is inescapable if the increasing pollution by carbon dioxide emission continues relentlessly. One evidence of this change is global warming and its impact in the Arctic Ice. The critical role of the Arctic in the global climate system implies that Arctic Ice changes will have far-reaching connotations for, and feedbacks to, the entire Earth. Currently, the warning signs include: rapid diminishing of sea ice, increased mass

“Antartica was once a lush, green continent, icing over only in the past thirty five million years…” said paleoclimatologist. If these studies are correct, our earth has already had sea levels rise this drastically. Although, we do not want this to happening again due to the costs of damages and possible lives, we know that the earth has already been through it and knows what to expect.

Greenland has lost 250 cubic kilometers of ice in a 4 year period, and Antarctica has lost 150 cubic kilometers. Sea ice in the Arctic is also significantly decreasing, melting at a rate of 13 percent per decade, according to NASA. On March 19, 2015 the National Snow and Ice Data Center (NSIDA) reported that the Arctic sea ice has reached the lowest on record. These two ice forms melting at such rapid rates it contributing to the raise in volume of the oceans that we looked at in the previous paragraph. In addition, the snow cover in many of the world's mountains is decreasing. Snow is highly reflective, and very often light is reflected back into space instead of warming our atmosphere. As the snow melts in the summer, more heat is absorbed; and satellites have captured that snow is melting sooner that it usually does. The effect of our carbon emissions are very widespread, and it is killing our planet at an increasing

The world warmed by about 0.7°C in the 20th century. Every year in this century has been warmer than all but one in the last century (1998). If carbon-dioxide levels were magically to stabilize where they are now (almost 390 parts per million, 40% more than before the industrial revolution) the world would probably warm by a further half a degree or so as the ocean, which is slow to change its temperature, caught up. But CO2 levels continue to rise. All this affect the ice pack in the Arctic. As temperature rises, ice melts. This causes many problems.

One of the global warming changes our planet is going through is the melting of glaciers in the Arctic sea. John Hawkins states, “How much Arctic ice really matters is an open question since the very limited evidence we have suggests that a few

“The Glacier, and with it the Duck, might have moved since then.” Lou Sapienza is the lead organizer of a Coast Guard Operation searching for a missing World War II plane; the Grumman Duck and its lost crew. A challenging problem the party has with finding the Duck is the movement of glaciers since the planes went down close to 70 years ago. Since the 1950s the extent and the movement of the ice sheets have rapidly changed due to Global Warming. Most affected by this climate change is The Arctic, Antarctica and the Greenland Ice Cap. Lou Sapienza and his team of specialists only have a hand-drawn map of where the Duck crashed and an old radar survey from years ago. Their daring task is to predict how the movement of the ice sheet accelerated by global warming might have moved their missing plane. Since global warming is a problem, everyone will be affected by it in one way or another. It is time to act, to confront the problem and find a solution.

Ice is one of the first indicators of global warming actually occuring and it is important for research to be done on these layers of before they disappear. The recession of glaciers and the fragmentation of ice caps has been a clear sign to many that rising temperatures are having an impact, even on our very lives.

The Arctic is global warming’s canary in the coal mine. It is a highly sensitive area which is profoundly affected by the changing climate. The average temperature in the Arctic is rising twice as fast as elsewhere in the world (nrdc.org). Because of this, the ice cap is getting thinner, melting away, and rupturing. Here is an example of this; the largest ice block in the Arctic, the Ward Hunt Ice Shelf, had been around for 3000 years before it started cracking in 2000 (nrdc.org) By 2002, the Ward Hunt has cracked completely through and had started breaking into smaller pieces. The melting ice caps are affecting the earth and its inhabitants in many ways. In this paper, the following concepts and subjects will be
