It's also roughly 1.2 million square kilometres smaller than the long-term average measured from 1981 to 2010. The situation isn't any better in the south, either. There is less sea ice surrounding Antarctica today than there was since reliable records began in 1979. The director of the National Snow and Ice Data Centre, told US broadcaster CNN, recently. The extent to which the ice at the poles is melting is considered an indicator as well as a consequence of global temperature rises.

Why is the Arctic melting faster than the Antarctica?
A new report says the Arctic may be ice-free by 2040. The Antarctica is also melting, albeit far slower, and in a less

While the outlook is bleak for the Arctic, there is a silver lining for the Antarctica: The ice is melting at a slower rate than previously thought. Although glacier flow has increased since the 1990s, scientists from University of Leeds have found the melting rate to be only around a third of what was previously …show more content…

On the other hand Antarctica region is also predominantly effected by global warming along with increasing expeditions, framing of policies to conserve south Australian waters and surveys of South Polar Region, it is also creating a new opportunity for tourists to explore such challenging destinations with the development of new sea routes to various parts of this region.
Further, governments are also taking active part in framing environmental protection policies and clamming their land over these highly sensitive and resource rich areas of the world. Countries like Australia as the member of Paris agreement on Control of Carbon emission from industries are reforming their policies to protect such areas. Media release by the Climate institute of Australia said they are getting positive response from many business leaders regarding Paris –agreement on control in Carbon emission from factories.
In medieval literature, the role of women often represents many familiar traits and characteristics which present societies still preserve. Beauty, attractiveness, and grace almost completely exemplify the attributes of powerful women in both present and past narratives. European medieval prose often separates the characteristics of women into two distinct roles in society. Women can be portrayed as the greatest gift to mankind, revealing everything that is good, pure, and beautiful in a woman's life. On the other side of the coin, many women are compared to everything that is evil and harmful, creating a witch-like or temptress quality for the character. These two aspects of European culture and literature show that the power of women in medieval narrative can be portrayed through both evil and good, and more often than not, power is derived from the latter.
However, climate change is happening. The global average land and sea temperature has increased over the twentieth century, with the North and South Poles being particularly affected (Learmonth, et al., 2006). In turn, this has caused ice cover to decrease and sea levels
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.
The planet we live in, the earth is a tiny composition in this huge universe. It has diversities ranging from highly variant temperature and pressure belts as well as various ecosystem types. One such remarkable feature of the earth is the polar ice caps. There are three major prominent features, the Antarctic ice on the South Pole, the Arctic ice on the North Pole and Greenland on the north between North America and Europe. Antarctica consist about 90 percent of the world's ice (and 70 percent of its fresh water). It is covered with ice an average of 2,133 meters (7,000 feet) thick. If all of the Antarctic ice melted, sea levels around the world would rise about 61 meters (200 feet). The Arctic ice is not so thick in comparison and it mostly floats in the Arctic Ocean. Greenland, on the other hand would add another 7 meters (20 feet) to the oceans if it melted because Greenland is closer to the equator than Antarctica, the temperatures there are higher, so the ice is more likely to melt. Scientists from the Universities of London and Edinburgh say that ice loss in Antarctica and Greenland together contribute approximately 12 percent of the rise in sea levels. The melting of these enormous ice bodies can significantly impact the global changes in climate and reversely, this climate changes also impact the melting of the ice bodies. It is a two way process and the causes are mostly anthropogenic.
The majority of glaciers surveyed in Alaska are melting. Thinning rates in the last several years are more than twice those seen in previous years. Half the water flowing into the oceans, globally, due to the glaciers, is because of the ice melting in Alaska.
Nowadays climate change is the biggest problem of the human being. It is already happening and represents one of the greatest environmental, social and economic threats facing the planet. Climate change, also known as global warming is the seasonal change for a long geological period of time in the world that is attributed directly or indirectly to human activity, altering the composition of the global atmosphere. Australia faces significant environmental and economic impacts from climate change across a number of sectors, including water security, agriculture, coastal communities, and infrastructure.
Climate change is on the international policy agenda primarily because of warnings from scientists. Their forecasts of a potentially dangerous increase in the average global temperature, fortuitously assisted by unusual weather events, have prompted governments to enter into perhaps the most complicated and most significant set of negotiations ever attempted. Key questions - the rapidity of global climate change, its effects on the natural systems on which humans depend, and the options available to lessen or adapt to such change - have energized the scientific and related communities in analyses that are deeply dependent on scientific evidence and research.
The topic of climate change and global warming has always been one of great debate and controversy; however, it’s clear to see that Canadians should take precautions to avoid the problems their country faces. The Canadian government should do everyth...
Climate change has been a growing issue in Canada’s arctic that the nation has seen over the past few decades, and protecting the arctic environment is crucial task that needs to be exercised. Though strategies have been developed in prior years, Canada’s arctic is now facing severe consequences of climate change more than ever, and it is vital that future strategies are made to be effective enough to minimize the threat of climate change. After examining many potential policies that could be beneficial to help diminish the negative effects of climate change in Canada’s arctic, I have discovered three prominent ones to address in this policy brief. The first policy I am analyzing is having Canada sign the Paris Agreement. I then will evaluate
Climate change has the potential to devastate millions in Australia. Rising temperatures will impact the landscape of Australia by decreasing Australia's forests. Australia is going to have to spend billions of dollars to make sure their safety from climate change. The people in Australia will need to be strong and flexible to make it through this tough time they're going through, and Australia will have to find a way to fix this problem before it's too late. Climate change is something that will affect the entire world and it's not an issue to take lightly. Australia’s solutions are not simple at all and in order for them to work everyone will have to work together. Climate change in Australia will impact the environment, the economy, and the lives of Australians, an example of a solution is to cut down on carbon emissions.
With talk of global warming still being threatened by scientists and governments, the depletion of the polar ice is a major concern. Many experiments have been done to monitor current ice levels and predict future ice levels. Since then scientists have tried to discover what would cause the melting of our polar ice. One major concern is that the melting of the polar ice would create extreme flooding for all costal and island inhabitants. Is the polar ice melting and could greenhouse gases be the cause?
Global Warming, much of what does or does not happen forty years from now rests on our actions or inactions taken between now and then. The crucial question is whether we should pour all our resources into mitigation – reducing our carbon emissions. According to scientists who study the climate there are other environmental problems; “we now face a global crises in land use and agriculture that could undermine the health, security, and sustainability of our civilization”.
The greenhouse gas emissions, global warming, carbon emissions and other climate changes can’t be putted in one country’s border it affects all nations no matter where they are geographically located. This is the main reason why the EU collaborates with ...
The polar regions are most affected and vulnerable to the warming temperatures because the poles are covered in ice. The world’s ice sheets are melting faster than ever and temperatures in the Arctic region are rising twice as fast as anywhere else on Earth according to the NRDC. This will have a serious impact on people, wildlife and plants in that region. The National Climate Assessment has said that “By the year 2100, it 's estimated our oceans will be one to four feet higher, threatening coastal systems and low-lying areas, including entire island nations and the world 's largest cities, including New York, Los Angeles, and Miami as well as Mumbai, Sydney, and Rio de Janeiro”. Polar bears are in great threat as the ice sheets melt because they use the ice to travel across the land and hunt. As the sea-ice platforms move further apart, the swimming conditions become more dangerous. The U.S Geological Survey done by the National Wildlife Federation predicts that by the year 2050, two thirds of all polar bears will disappear. Researcher Bill Fraser has tracked the Adelie penguins in Antarctica and reported the numbers have fallen from 32,000 to only 11,000 over the last 30
... of extreme weather and melting ice caps are indicators of global warming. Because these things will affect society, there are important decisions that have to be made in the present as well as in the future to secure people’s lives and lifestyles. The world community is aware of this serious issue and do already prepare for projects to slow down global warming, but they still have to improve. If the world leaders stop worrying about this issue, the future generations could be in danger. The future lifestyles will be affected by the decisions made in the present day. Society has much to improve to save energy and to lower greenhouse gas emissions. There are also small things people can do to help. Individuals can live a life without wasting energy or polluting the environment. Without effort, global warming endangers the quality of life for the future generations.
