The Ozone Hole And Polar Regions

Over the last several years, researchers in the Arctic have begun closely monitoring the temperature and the alarming effect it seems to be having on the climate. According to researchers, the Arctic is having abnormally high air temperatures and sea surface temperatures, which are causing the melting of the ice leading to record breaking lows of ice. To the north, the Arctic is almost 100% ice and snow. The southern parts of the Arctic are where you can find more vegetation along with dense forests.

The Earth 's atmosphere has changed all through history. Just in the most recent 650,000 years there have been seven cycles of frigid progress and withdraw, with the sudden end of the last ice age around 7,000 years back denoting the start of the present day atmosphere period and of human development. The greater part of these atmosphere changes are credited to little varieties in Earth 's circle that change the measure of sun based vitality our planet gets. Exploratory proof for warming of the atmosphere framework is unequivocal. The present warming pattern is of specific criticalness in light of the fact that the vast majority of it is likely human-impelled and continuing at a rate that is exceptional in the previous 1,300 years. Earth-circling satellites and other mechanical advances have empowered researchers to see the comprehensive view, gathering a wide range of sorts of data about our planet and its atmosphere on a worldwide scale. This group of information, gathered over numerous years, uncovers the signs of an evolving atmosphere. The warmth catching nature of carbon dioxide and different gasses was shown in the mid-nineteenth century. Their capacity to influence the exchange of infrared vitality through the environment is the logical premise of numerous instruments flown by NASA. There is no doubt that expanded levels of nursery gasses must bring about the Earth to warm accordingly. Ice centers drawn from Greenland, Antarctica, and tropical mountain icy masses

Climate change is going to affect the arctic more dramatically than other parts of the world. A study has shown that the average temperature has risen over 2ºC from 1960-2011 ("Climate Change In the Arctic"). Just a couple weeks ago the arctic was 20ºC higher than usual. Rising temperatures are going to affect the sea ice and glaciers, vegetation and wildlife as well as infrastructure. Of course these things won't just disappear quietly, they will take many other things down with them.

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

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

The increasing global temperatures have caused many problems in Arctic ecosystems. The increasing warmth has caused ice caps to melt, and permafrost to thaw, causing shifts in the ecosystems around them. 1According to Harris (2005) “Permafrost is soil, rock or sediment that is frozen for more than two consecutive years. In areas not overlain by ice, it exists beneath a layer of soil, rock or sediment, which freezes and thaws annually and is called the "active layer".” (p. 17). While the melting of ice may not seem like a big issue at first glance, its effects are truly catastrophic. Many professionals in this field, such as Houghton (2009) have said 2“Warming is expected to be strongest in the Arctic, with the continuing retreat of

The North pole is one of the main places affected by global warming . The Arctic and the Antarctica are both vulnerable to the climate that has changed overtime. The ice caps have promptly melted overtime that they are now differently than they were. (The Arctic ice cap is less than ten feet thick on average). The ice are spread apart floating in the ocean making it hard for animals such as the polar bear to travel one place to another. This creatures must now swim through long distances of waters some becoming exhausted and drowning before reaching to the next

The first argument examined on the man-made global warning side is that increasing greenhouse gases caused by human activities is causing directly observed climate changes. The first resulting climate change discussed is warming global surface temperature. There has been an increase in global surface temperature of 0.74 degrees C since the late 19th century. In the last 50 years alone the temperature has increased by 0.13 degrees C per decade. North America and Eurasia have seen the largest increase in warmth. However, some areas of the earth have actually cooled some this past century (Easterling & Karl, 2011, para6). After the mid 20th century 70% of the global land mass saw reduced diurnal temperatures. From 1979 to 2005 the maximum and minimum temperatures have shown no change; both indicate warming (Easterling & Karl, 2011, para10). Furthermore, borehole temperatures, snow cover, and glacier recession data all seem to agree with recent warming (Easterling & Karl, 2011, para11).

The Ozone layer had been depleting since recently. The hole has started healing itself back due to the banned substances such as Aerosols. The Ozone layer will help block out solar radiation as well as bring climate change to a halt, however, scientists say that a pause in climate change does not mean a complete and forever stop (http://www.dailymail.co.uk/sciencetech/article-3699735/The-Antarctic-COOLING-Region-bounces-ozone-damage-scientists-insist-global-warming-taking-place.html).

[1] Industrial activities, such as fossil fuel burning and other human activities such as tropical deforestation have increased greenhouse gas concentrations in the atmosphere. Increasing global temperatures are likely to have extreme effects on global climate and may result in species extinction, changes in agricultural production and deleterious effects on health. Studies have been conducted in recent years on the effects of increase of greenhouse gases on the thermohaline circulation. There are several hypotheses that state that the prolonged effect of global warming could eventually “shut down” the thermohaline circulation and lead to cooling in certain regions in

The most well-known climate change must is the global warming due to the inclination of greenhouse gas in atmosphere, which is a common issue for all human beings and ling creatures. For examples, the melting of arctic glaciers, one of the most critical consequences of global warming, has caused severe damage to the species diversity of the living creatures of entire Arctic Circle. Polar bears and seals are two of most influenced living creatures in Arctic Circle since their habitats have been highly eliminated and invasive creatures have severely negative influences on their life. Now, although many countries have acted to rescue polar bears and seals, but scientists predicted that their situation would continuously worsen in the future.

Most of the world’s population has little knowledge on how important the Arctic truly is. The ice in the Arctic is melting at one of the fastest rates in human history. During the summer season a certain amount of ice is estimated to melt, this wouldn’t have been a problem a few decades ago, the winter storms and cold would replenish the ice lost over the summer, keeping the total amount of ice in the arctic relatively stable. But now, the total amount of ice in the Arctic decreases all year long. The Arctic regulates the Earth’s temperature, acting like an air conditioner. The acceleration of the Arctic melting has played a role in the extreme weather events over the past few years, such as; unpredicted heat waves and droughts in the U.S.

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

Climate is part of our everyday lives. What we experience is the global climate system. According to the United Nations Framework Convention on Climate Change, climate change is, "a change of climate which is attributed directly or indirectly to human activity alters the composition of the atmosphere and which is in addition to natural climate variability observed over comparable time periods." (Allen, Seaman & Delascio, 2009) Australia’s climate has warmed a lot more since 1910 by the average of 0.9’C. it has been rising dramaticllay since 1950’s.the daytime temperatures have increased by 0.8’C whereas in the night time, we experience 1.1’C more heat than the people living in 1900’s. (BOM & CSIRO, 2014). In 2004 more than 234 newspaper articles have concluded that we may have, in fact, reached the tipping point for the climate change. Walker (2006) believes that this man made climate change has caused havoc on the earth’s atmosphere and the most striking of all the components is the arctic. Farthest north is the carapace of sea ice over the Arctic Ocean. South of that is the vast ice sheet that covers Greenland. And then there is the ocean conveyor belt, which originates in a small region of the Nordic seas and carries heat and salt around the world.

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
