Antarctica is very cold, much colder than the Arctic, so global warming down there hasn't made much noticeable difference yet.
Under the Antarctic Treaty, there is no covenant that addresses melting ice in Antarctica. Please know that the continent will not melt, but the ice sheet that covers 98% of the continent is subject to natural melting, which is not illegal.
The excessive melting of Antarctic ice would lead to global rises in sea levels. Many low lying countries like Holland, Bangladesh and Pacific Island countries would be flooded. Coastal areas of most countries around the world would be underwater. It would also indicate that almost all satellite measurements and our best metering equipment is wrong. It would throw the concept that we understand the planet back by decades as all of our modern equipment shows the Antarctic is not melting or losing ice. The Antarctic has been gaining ice for decades. The same could be said if the Arctic was shown to not be losing some ice. Our measurements on just about everything would become suspect.
Yes, melting point is a physical property because melting is a physical change, and does not produce any new substances.
Glaciers and ice caps are melting. The ice over Greenland is melting and so is the Arctic sea ice.
The Antarctic ice could not conceivably melt entirely within the next few thousand years, because it is so large. In fact, only the small Antarctic Peninsula, to the south of South America, seems to have been noticeably affected by recent global warming. The arctic sea ice is melting, but melting sea ice does not really affect sea levels. The worst that could happen here is the extinction of the polar bear, and perhaps changing weather conditions in some parts of the northern hemisphere. Since sea ice is reflective, it has a cooling effect, so the loss of sea ice can also contribute to global warming. As the ice shelves and glaciers of the arctic region melt, sea levels will rise, as they have already begun to do.
Most animals are endangered because of hunters and also animals from the arctic areas are endangered because of global warming. Ice is melting so polar bears and other animals have no ice to rest on so they have to swim longer and they eventually get tired and drown.
Well it is affecting the Arctic and Antarctic the most mainly because of the ice melting. And of course coming out to be no help for the animals living there
Yes because the ice is melting from global warming
they are endangered because the ice is melting and there is less food to find. hey i love polarbears and am a 4th grader so i think it is right. I studied polarbears. I have tons of stuffed animals of them
Because when the Antarctic was melting in 1902, scientists decided to move the animals to North America so they would not drown. They have since become a popular pet in Canada and America, and scientists plan to reintroduce them to the wild when the Antarctic grows back sometime in 2013.
Pollution is one thing. Also, some species are becoming endangered because of hunting. Some animals are poached for their parts (elephants for their ivory tusks, tigers for their fur). Also there is global warming, melting the ice caps. That's not good for the polar bears.
The Arctic
because the ice is melting
Because Greenland's ice shelf is melting, while the Antarctic's is increasing in depth.
The Antarctic is constantly changing due to melting ice caps. The latest figures state the Antarctic is 413,129 Sq Mi (1.07 million km2).
Global warming has had some impact on the animals of the Arctic and Antarctic (there are actually no animals at either Pole). Being an ice shelf, rather than a land mass, the North Pole is more prone to melting, decreasing in size over at least the last five decades. Currently, global warming affects animals because the melting of freshwater ice affects the marine creatures. These creatures also cannot withstand the warmer sea temperatures. Habitat loss is a major issue. In the Antarctic, there has been a 33% decrease in some penguin populations due to habitat loss.
The GLOBAL WARMING is melting the ice that they need to live on.
