Sea ice is a frosted sea located in ocean especially in the Arctic and Antarctic. Sea ice influence the movement of the sea water in the oceans. Polar areas is the most area that sea ice located in, so the temperature in the polar regions remains the same which mean very cold. Water in the oceans affected by the sea ice. Sea ice can influence the polar system in the ocean water.
Sea ice is important for global climate. It separates the ocean from the atmosphere which is cold. Sea ice influence sunlight’s amount. It is essential for the human activity. In 2015, sea ice distance decreased to 4.41 million square kilometers. In addition it reached the minimum distance on September 11. The extent of sea ice increased through two seasons which was
Forests control the amounts of carbon dioxide in our atmosphere therefore contributing to global warming. However we as a planet have a problem… deforestation.
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
Macbeth is a courageous war general who receives a prophecy from the mysterious three witches that he will someday become the King of Scotland. Although skeptical at first, Macbeth knows better than to question the witches. He lets this prophecy over take him and with the encouragement from his wife, Lady Macbeth, they murder King Duncan and become engulfed with both regret and insanity. This insanity leads to Macbeth unnecessarily murdering other citizens in order to “secure” his throne. At the start of this play, Macbeth and Lady Macbeth are polar opposites, as Macbeth is self-aware of his actions while Lady Macbeth refuses to worry about her consequences. However by the end, their feelings of guilt completely switch. In Macbeth, Shakespeare uses the story of these murders to portray the effects that Macbeth’s diminishing guilt will have on his relationships. Macbeth’s lack of guilt will destroy his relationship with Lady Macbeth, alter Macduff’s feelings towards him, and overtake his own actions.
As ocean temperatures increase due to global warming they increase ice melt of these ice sheets and glaciers by melting the floating ice from below. If the air temperatures increase then the ice will begin to melt from above, creating pools of melted water that will in turn melt more of the surrounding ice. This may not always result in a problem as it’s expected that ice sheets reduce in size in the summer months but recently what has been found is that less ice is formed during winter so in total the ice sheets and glaciers are being reduced in size, adding more and more fresh water to our
Albedo always has a reflection coefficient ( the amount of electromagnetic wave reflected) of less than 1, that goes from 0 (no reflection) to 1 (perfect reflection) (Coakley, 2003). Factors that go into the amount of albedo is the angle the light and the wavelength of the light shone on the ice. The absorption of solar energy causes surface temperatures to increase, evaporating water and melting ice and snow (Coakley, 2003). Hence making albedo one of the leading causes of climate change. Sea ice is classified in many ways. There are many variations of sea ice that differ from ice thickness to growth rate and to age of the ice (Light et al., 2003). Sea ice that has no more than one year of growth from fall to winter are considered first-year sea ice (FYI), also known as young ice. Multi-year sea ice (MYI), also known as old ice, is ice that has survived more than one summer melt. It is also much thicker than first year ice, but throughout the years there has been an increase in first-year sea ice and a decrease in multi-year sea
In order to provide context for the recent decline of ice in the sea, it is imperative to understand how the sea ice has varied over the past two centuries. Of particular interest, the period around 1920-1940 showed an “increase in almost twice the global average rate in past 100 years. [ ]” The warming during this time can be used to compare the decline of sea ice observed since 1979, but what will also be discussed is how this time period was also quite controversial due to its substantial variance between the official views and views held by other people. The reliability of the sea ice observations during the first half of the 20th century according to some people cannot provide certainty to estimating
As important as it is, Arctic coastal sea ice plays a vital role in dynamics of the coastline, covers stretches of open water which serve as important biological habitats, and serves as a platform for a broad range of activities by residents and industries (Druckenmiller et al., 2009). Sea ice is also important because it is used as a platform for harvesting seals and whales in spring, transport of personnel and supplies to camps, and as a network of trails (Druckenmiller et al., 2009). Dangerous effects of climate change include “ice breakouts” which are when large chunks of ice that whalers are using as working areas break off of the main ice blocks and take whaling camps out to sea (Druckenmiller et al.,
It has been observed through various researches that in the last century, average temperatures across the globe increased by over 1.3°F with an increase of more than two times in the Arctic. (Bates, Kundzewicz, Wu, & Palutikof, June 2008). The results of climate change can also be seen in changing precipitation patterns, increases in ocean temperatures, changes in the sea level, and acidity and melting of glaciers and sea ice (USEPA, 2014).
This essay will explore how the media shapes the formal and informal policing of child murders within the family. Through case studies, an exploration of government policies and legislation, the essay will illustrate how the media has created moral panics around stranger danger, despite the fact that major harm to children is generally caused by families and their friends. Throughout our upbringing one is taught not to speak to strangers because they are the ones who are most likely to bring harm upon us. The people found most trustworthy are normally family members and family friends. Most people would, without a second thought trust their children’s life with family or friends. This essay will explore definitions of the family, moral panics, formal and informal policing. Furthermore, this essay will seek to address how the media is seen to be the fourth estate of power. It will also discuss the power of the media and how the media frames and shapes moral panics, which consequently might give a misleading picture of the situation, through the demonization of strangers and how the media labels individuals within society. Finally, in order to answer the above question, the essay will look into cases and legislation to identify how governmental agencies have failed children who are deemed at risk.
Since the industrial revolution, scientists have documented a trend of increasing atmospheric carbon dioxide (CO2), the main greenhouse gas. This observation has been an issue of major environmental concern in the view of the potentially devastating effects of climate change on ecosystems and human survival. Recent studies by scientists led by Wei-Jun Cai have served to underscore this fact by showing that the Arctic region and the globe are faced with a major climate challenge due to the continued melting of sea ice in the Arctic Ocean. This research has indicated that the major concern is the increasing heat absorption as deeper ocean water layers get exposed to sunlight as well as the possible loss of white ice reflectivity or the
Sea ice depletion and retreating is becoming significantly severe nowadays. It draws increasing attention from scientists, environmentalists and public. Global warming trends and increased anthropogenic activities in Arctic region are the main factors contributing to sea ice extent problems. In addition, a vicious circle would occur, as if further sea ice extent problem deteriorates, marine fisheries, socio-economic development and ecosystem would have to confront significant threats and challenges that give feedbacks to sea ice (ACIA, 2004).
The argument’s main idea is that melting glaciers may have a negative impact on the environment, but they are allowing scientists to make new discoveries. The author, Alan Burdick, develops this argument by explaining that glaciers are melting at a rapid rate, which causes disruptions in the ecosystem. However, scientists are able to find artifacts that were once frozen in the glaciers. These artifacts would have been unavailable to scientists if the glaciers had not started melting. Many of the ancient items are in perfect condition because they were frozen in the ice. One example of a recent finding is a wooden box that is believed to have stored food. The article shows how these artifacts help scientists have a better understanding of the
Plato created an academy dedicated to geometry. He had a bunch of successful scholars that attended his school. Some scholars stayed for plato, but others left to alexandria to further their studies. Plato’s academy was dedicated to geometry, and it was extremely important then, and it is even important
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.
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.
