Over The Past Couple Of Decades, The World Has Recorded

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

Global warming persists as one of the world’s biggest issues today that is causing several problems that include the world’s severe climate and rising sea levels while possibly being the main cause as to why all of mankind could go extinct. This global crisis is known as the steady increase in the world’s average temperature of the earth’s atmosphere and oceans that are proven to be permanently changing the world’s climate (Live Science, 2014). This phenomenon is strongly evident as Earth’s temperature has also increased by 2 degrees Celsius since the last century. As a result of this, Canadian glaciers are melting at a higher rate of 2 to 3 feet than of what it was a decade before (Lerner, 2014). All astoundingly happening while the Artic Canadian permafrost has begun to melt (Davidson,2015). The state of this issue in Canada does not seem to be improving as validated through both the scientific evidence as well as the blatant and irrefutable observable evidence.

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

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

Decades of research suggest that sea-levels are rising, and will continue to rise as a result of climate change. This rise will have the most immediate and significant impact on

Climate change is causing glaciers to melt. In the video it says “when the ocean gets warmer it swells on top of that glaciers and ice sheets are melting”. This is important because it shows glaciers are melting because the ocean is too warm. This

As Earth’s surface temperature rises, the ocean also becomes hotter which results in an increase in sea level and decrease in Earth’s ice. “The oceans have absorbed much of this increased heat, with the top 700 meters of ocean showing warming of 0.302 degrees Fahrenheit since 1969” (“Climate Change: How Do We Know?”). Since greenhouse gases are trapping energy from the sun, the oceans absorb more heat which ultimately increases surface temperature. Oceans are able to absorb large amounts of heat energy because water has a greater heat capacity than air. As oceans become warmer, the frozen water on Earth melts at an accelerated pace. The thickness of Arctic Sea ice has dramatically declined throughout the last several decades. “Arctic sea ice

The cryosphere refers to the frozen water part of the Earth system including the frozen parts of the ocean, such as waters surrounding the Arctic. Recent studies show that the cryosphere is generally in a poor state, and scientific agreement stated that average global temperatures will continues to increase over the next century. This means that the existing risk to these climatically sensitive areas is increasing. In the past 20 years, the amount of summer sea ice in the Arctic has decreased dramatically, and could even disappear completely within the next hundred years. Evidence shows that some of these depletions in the cryosphere are human-induced, specifically the fragmentation of sea ice when oil tankers break through the frozen waters to make a passageway. This fragmentation leads to global sea rise and habitat destruction for large predators such as polar bears and seals, in addition to other Arctic wildlife.

The problem is that the arctic melt has caused global warming and climate change. In the Arctic, the ice is melting and the air is warming. Unfortunately, the Arctic ocean is taking in a lot of sunlight which causes it to become even warmer. Ice and snow cover take up a smaller space and used to be only present for under a year, but now that number is even less. As this happens, permafrost warms. As the years go on, mountain glaciers, sea ice, and the Greenland ice sheet melt faster and faster. Throughout this century, the Arctic ocean will have a limited amount of ice or will have no ice at all. Climate change is to blame for the arctic melt.

Wow, the facts in this article were pretty scary. The trend with glaciers is that they are rapidly decreasing. It states that the Columbia Glacier in Prince William Sound in Alaska is the world's fastest-melting glacier. It moves 80 feet a day into the ocean. Also, the thickness of this glacier is usually 3,000 feet but over the last 25 years it reduced to only 1,300 feet. Global warming is responsible for glaciers to weaken until they collapse. The article also points out that summers in the Arctic could be no longer icy in 100 years, which would endanger the polar bears. As temperatures increase, glaciers recede and the faster glaciers melt, the faster seas will rise. The loss of glaciers also has consequences for park ecosystems and the

Glaciers are one of the most fundamental phenomenon on the planet, and much of their purpose and impact on earth has been well documented and published. Ice sheets, Ice Caps and Glaciers trap nearly 90% of the world's fresh water, and are replenished by snowfall each year. Their existence on this planet dates back 650,000,000 years and yet they are always moving, always shifting and always melting. Before, human existence and even during the brief era of humans, ice dominated all of the earth's landmass and have regulated, created and altered many of the landscapes around the world.

Glaciers serve as an important indicator to the changes occurring on Earth. Global warming and climate change are definitely observable changes. For more than a century, Earth’s temperature has been increasing dramatically, thus contributing to the melting of Earth’s glaciers. Melting is observed in the ice sheets of Antarctica, Greenland and non-polar glaciers found around the world (Nat Geo). A small amount of ice is stored in non-polar glaciers in comparison to ice sheets. However non-polar glaciers have had a significant effect on sea-level rise. Non-polar glaciers have higher mass-balance sensitivity than the large ice sheets of Antarctica and Greenland. It is estimated about half of sea-level rise is attributable to the shrinkage of non-polar glaciers, according to glacier mass-balance data (Fujita). Some non-climatic factors that affect mass balances include oceanic circulation, sliding rates due to basal water supply and stability of ice shelves. Climatic factors include precipitation, temperature and sunlight. Recently, the spotlight has been placed on human impacts, particularly the

However, since Antarctica is a big place, climate change is not having a uniform impact, with some areas experiencing increases in sea ice extent. Yet in others, sea ice is decreasing, with measurable impacts on wildlife. Local Antarctic effects of climate change are only part of the problem. Antarctica comprises two geologically distinct regions, East Antarctica and West Antarctica, separated by the great Trans-Antarctic Mountains but joined together by the all-encompassing ice sheet. The presence of the high ice sheet and the polar location make Antarctica a powerful heat sink that strongly affects the climate of the whole Earth. Furthermore, the annual sea ice cover around the continent, which seasonally reaches an area greater than that of the continent itself, modulates exchanges of heat, moisture, and gases between the atmosphere and ocean and, through salt rejection when it freezes, forces the formation of cold oceanic bottom waters that spread out under the world’s oceans. Alterations to this system will affect climate all over the planet.

The polar ice caps are melting faster over the last half century moreover than the last five centuries. This is a big concern for the population of the planet. The people that live near the coastal areas are in the most danger. Some believe that this melting will cause the next ice age. What is causing the ice to melt? The ice caps are melting due to global warming, and the effects of this are rising because of the sea levels and drastic change in the weather patterns. This change in our environment is caused by several events.

Scientists therefore know that, “About half of the past century 's rise in sea level is attributable to warmer oceans simply occupying more space” (National). Depending on the volume of greenhouse gases emitted, “The Intergovernmental Panel on Climate Change reported that by 2100 sea levels could rise 28 to 98 centimeters (11 to 38 inches),” and on either end of that scale, Earth would face massive consequences (Folger). The chief cause of sea level rise is definitely the higher temperatures on Earth, but they are not just causing the ocean to expand. Glaciers in the North and South poles are melting at an alarming rate, and their runoff is also a significant contribution to oceans. Scientists believe that, “As it melts the ice from beneath, the warm water is loosening the connection of the glaciers to the ground and to nearby rock,” which then causes them to break off more easily than they would have if attached (Gillis, 11-13-10).
