Solutions with the summer and much talk about high temperatures I find it will be interesting if we talked about the polar frozen continent in this article to show some scattered about the facts and the melting Thelugea that threatens marine life and the coastal cities.
In the beginning to show some of the points, the Earth's geographic poles, one is located in the south and the other in the north when these electrodes intersect the Earth, "the circular lines that appear in the image below hubs". We must distinguish between these two poles and the poles Amonatisien of the land and who are determined based on the Earth's magnetic field and are located in an area close to them geographically.
Arctic - Arctic polar region is located "on" the Arctic consists of the Arctic Ocean and parts of Canada, Russia and the United States (Alaska) and Denmark (Greenland), Norway, Sweden, Finland and Iceland.
Ontarkik - Antarctic polar region is located around the Antarctic continent and is made up of Antarctic ice shelf giant Iceland and parts of the Southern Ocean.
Antarctica - Antarctica is Antarctica, which contains the South Pole is located in the southern polar region Ontarkik As we mentioned a moment ago, and is the fifth continent in terms of area after Asia, Africa, North America and South America and is almost twice the size of the continent of Australia.
Ice covers 98% of the continent's southern area a thickness of up to 2 kilometers !! And a temperature of up to 89 below zero !! However, it is surprising to know that the southern continent is desert rain at a rate of barely up to 200 ml in the coastal areas and less so on land! .
Live on the continent from 1000 to 5000 people, all living in the research centers as well as some types of algae, bacteria, fungi and some animals such as penguins and seals. Unlike the northern region divided between almost 8 countries and South continent is protected under the Charter, signed by 49 countries in 1956, which prevents any military activities and deprives search for and extract resources or disposal of nuclear waste, and at the same time had to be cooperation between them to support scientific research.
A few days ago news broke about a massive collapse in the ice shelf in that continent and emerged several questions about the truth of the matter and what is really happening in the ends of the earth?
[divider] snow in the southern continent is increasing in size and not vice versa [/ divider]
Yes this is true snow volume in the Antarctic has increased and reached 19.5 million kilometers last year square increase in size by 4.5% for 1981, must distinguish between sea ice and snow formed on land, the one who scientists indicates melting is snow land because sea ice Ocean melts each year in the summer automatically separated.
What happens is that the melting snow from the land and thanks to the wind and cliffs caused the increase in snow volume in the ocean as well as other factors such as extreme changes in ocean temperature and salinity so that these factors contribute to the creation of new areas are snow to be in the ocean and reduce solubility. The same factors contribute to the melting of land ice process also, for example, wind contribute to the effect in the water cycle in the oceans that results in warm, which in turn sculpts snow land from the bottom, causing the water solubility.
[divider] It volcanoes inevitably [/ divider]
West of the continent is more vulnerable to melting places Theluge It also has a number of active volcanoes between the flanks So is it possible that these volcanoes are to be the reason behind the solubility and not global warming?
The answer to this question is no, why? .. First because many places around us prove that volcanoes and ice can be passing by in one place and the example of Iceland, which contain many active volcanoes and is still Thelugea as they are. Secondly, some of the evidence shows that the lava does not cause the melting of the ice actually One way the snow back again, add to that that the volcanic activity in the west of the continent has not changed since Sunni therefore unlikely to be a cause of melting. Finally, scientists have found that volcanic eruptions the size of those in the region is not sufficient to melt any form of heavy snow there.
[divider] plot of global warming [/ divider]
Actually there are 97% of the scientists assert that humans are the cause of global warming, but recent observations in West Antarctica have shown that the largest ice shelf in the continent began to collapse, researchers there and confirms that these landslides nothing to do with temperature, but you can imagine that such effect dominos, some of which affects some scientists expect that these landslides last for centuries and no one can stop it where there is no direction in the melting or collapse of any peaks or mountains limit the speed of collapse and valleys represents a path paved for him.
[divider] Ice Age is coming [/ divider]
Scientists believe that the Earth over the past 900 000 years passed cycles of high temperatures and low every 100,000 years interchangeably, and that it continued on that in the near future, the earth was moving toward an ice age is uncertain, but it is disturbing that there appeared an important factor in the picture .. what is it? .. We are! In addition to the gases and residues of aircraft and high rates of carbon dioxide and other pollutants that would inevitably affect the natural cycle in this environment.
[divider] will not drown one [/ divider]
Most snow in the Antarctic are stationed on land stretching down to the giant ice shelves in the oceans, so the snow Most of these do not affect the current water displacement, and the size of the ice melts when at least virtually so will reduce the level of the oceans and not vice versa.
Besides the scientists found that the melting of the ice dunes at the moment and since the end of the Ice Age was the cause of that land started moving towards the North Pole by 0.88 millimeters each year as a result of the decrease of the avalanche that results in higher land again.
Here this group of pictures that appear in the white beauty of Antarctica:
Now, what are your expectations of what might happen in the next period of the Earth's climatic changes and their impact on life in it?
