Greenland is a large region along the coast of northwest Europe. The Greenland ice sheet covers more than 35 percent of the Greenland Island and it is the largest island among all islands in the area. As a consequence of this large mass of ice, the temperature in this region is cold and people who live there have adapted to survive in these conditions. But a large part of Greenland is covered by land and this is where the Greenland Sumit Bank comes in.This bank is made from glacial deposits that are extremely rare but also very large. There are about two thousand glaciers in this large area and each one of them has its own ice field and drainage system. It is the only way that glacial melt water can be drained from the ice into the ocean. This is because the ice moves slowly and the currents in the area can keep large volume of ice moving for millions of years. This process of ice melting and water draining is very interesting for scientists. They study this process in detail through research expeditions like the Greenland Ice Study.Summers are when the ice gets very large, which causes the sea ice layer to thin and extend beyond Greenland's ice line. The North Atlantic ocean volume increases due to the melting of snow and ice, which helps keep the cold air out. This causes the chilly air mass to expand upward towards the southern poles. This phenomenon has been observed in the past centuries. By comparing the present with the ancient times scientists have been able to conclude that the present warm climate is due to the large melt of sea ice and this process is also likely to happen in the future.Researchers believe that the biggest impact of sea ice change on weather conditions could be seen in the winter months. The winter months are known for their temperature variations. A decrease in the thickness of ice could lead to warmer climate. At the same time it could also mean strong winds and more frequent rain. The warm air is likely to help generate clouds in the winter and this will consequently cause a change in the wind patterns. All these factors could lead to stormy weather conditions that could be accompanied with light rain.Some experts don't believe that a North Atlantic sea ice meltdown will have any significant impact on weather conditions. In fact they believe that the changes in climate have always been part of nature. According to them, large melting of ice will occur and it will help lead to fluctuations in the atmospheric pressure and this will cause slight variations in the temperature. The melting ice could cause precipitation to increase, which could lead to flooding problems in low-altitude areas. There is also the possibility of icebergs forming, which could lead to severe weather conditions in the area.Apart from all these there is also another side to take into consideration. If the Greenland ice breaks up into smaller pieces this will release the meltwater into the ocean. This will accelerate global warming by increasing the rate at which heat is disappearing from Earth. Satellite images have shown that large amounts of meltwater are being released from the ice each year and this is one of the reasons why experts believe that the Arctic region is facing more severe weather conditions than usual. They also believe that the meltwater is playing a major role in changing the wind patterns and the direction of wind near the Arctic regions.
