It was found that nearly all of the loss of ice happened in the Western Antarctic Ice Sheet. In another research, the volume of ice in Antarctica and Greenland was examined from 1992 to 2002 with the help of satellite radar altimetry. This study verified the findings of the previous study discussed above. Many species of animals are totally dependent upon the pack ice conditions. For polar bears, pack ice of the sea is the source of food and the place to live in. If the existing rate of melting of ice sustains for few more years, loss of ice in the sea will be sufficient to cause an altogether extinction of the polar bears. There has been some consideration about relocating them to Antarctica, but this would have its own repercussions. The drastic shifting might endanger the life of other Antarctic species along with that of the polar bears. Life of polar bears is endangered by the rapidly melting ice in the sea which is fundamentally happening because of an overall rise in the temperature of Earth caused by the global warming. ...Download file to see next pagesRead More

Pollution: Habitat of the Polar Bears the climate alterations which is gravely affecting their health conditions leading to deaths. The decrease in the sea ice also compels the Polar Bears to spend extended time periods on land which is raising the number of contacts with the humans leading to greater than before rates of mortality (Natural Resources Defense Council, “Polar Bears on the Thin Ice”; World Wildlife Fund, “Polar Bear: This icon of the North Is Losing Ground As Global Warming Melts its Sea Ice Habitat”) The World Conservation Union’s Polar...

Kyoto protocol will be of great importance in curbing the global warming B.1973 international agreement will result to increase of polar bears in the world. C. Amendments of the Endangered Species Act widen its implications ?­ Introduction In the contemporary world, global warming has not only jeopardized the health of individuals but also it has significantly affected the living condition of the animals especially those residing in oceans, seas and on the ice. Earlier on, human activities were viewed as the major contributors to the global warming. However, due to the industrial and...

Sea Level Rise Crisis
...of these forms will directly result in the sea level increment. Rising sea level is a justification or rather a proof that the world today faces a threat from the anthropogenic (human based) warming contributions, which in the late 20th century has caused the sea level to rise to new levels. The contribution to the rising levels is associated with Greenland, Antarctica, and the melt down of other important ice sheets and glaciers. The effects of the constant changes in the climate conditions and then the...

The Melting of the Polar Ice Caps
...the water level rise. The melting water from the glaciers drains into the sea and oceans leading to a rise in sea levels. Melting of ice caps and glaciers has negative environmental impacts. It destroys the ecosystems on which flora and fauna depend on. This leads to massive loss of bio diversity in the Polar Regions and the surface water. Decrease salinization of surface water in these regions also occurs (Singer 111). Skeptic scientist are of the idea that the melting of the idea that global warming does not cause melting of the ice caps stating that this in a perfectly natural...

Sea Ice Trends the Northern Hemisphere where the area covered by ice is already smaller as compared to latter. Arctic sea ice covers about 14-16 million square kilometers in contrast to 17-20 million square kilometers in the Southern Ocean (Daniel) and while the ice is rapidly melting in the Northern Hemisphere, it is gaining momentum in the other Hemisphere. The rising sea levels is seen as one of the worst consequences of the rapidly melting ice caps which has led a large number of people to move away from the coastal areas and settle down somewhere else. The increase noted in the evapotranspiration rates is also...

Polar ice and climate change
...? Polar Ice and Climate Change Over the years, studies have continued to illustrate the detrimental effects of the prevailing environmental degradation at the Polar Regions. This is as evidenced by the discovery of the Antarctic ozone hole and the reducing extent of the arctic sea. Consequently, there has been a rise in the sea levels owing to the melting of the polar ice cap, which in turn speeds up global warming. The Polar Regions are regarded as key influences of the world’s climate and with the melting of the polar ice caps has been attributed to erratic weather patterns. This is especially so with the ever increasing rate of melting attributed to the environmental degradation. For years, scientists have had their eyes set... voiced...

...melting of comparatively fresh sea ice. Thesis Statement: The purpose of this essay is to investigate Antarctica sea ice melt, examine the ocean-atmosphere interaction, and evaluate the environmental and societal impact of rising sea levels and other impacts of the sea ice melt. Background: West Antarctic Sea Ice and East Antarctic Land Ice Globally, there is a decline of snow and ice over the past several years, particularly since 1980, with an increasing downturn during the...

...Letter of Appeal Matt Rodriquez Secretary of the California Environmental Protection Agency (Cal/EPA) Re: Sea Level Change Dear Matt Rodriquez, Environmental sustainability is a critical aspect in the contemporary that has captured the attention of local, regional and international environmentalists. The role of governments and the society at large has been the central focus of environmental discussions, with concerns being raised on air, water and land pollution. Climate change and especially the consequences of global warming pose significant threats to environmental sustainability in current and future times. Specifically, sea level change has been the focal point of...

...the existing coast lines around the world recede back, but may also lead to the submersion of many islands and land masses (Rowe 22). The consequent rise of the earth’s temperature and ocean water levels will possibly lead to the extinction of many plant and animal species (Rowe 22). Although the full impact of a possible collapsing of the West Antarctic Ice Sheet is still being estimated on a hypothetical basis, there is no denying the fact that such an event will certainly have many foreboding consequences for the survival of the humanity on earth. Conclusion The possible collapsing of the West Antarctic...
