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. Because of the large amount of ice in this area, the temperature is very cold. People who live there have learned to adapt to these conditions. The Greenland Sumit Bank is located in a large area of Greenland that is covered by land.

This bank is formed from glacial deposits, which are very rare and at the same time extremely large. This large area is home to approximately two thousand glaciers. Each one has its own drainage system and ice field. It is the only way that glacial melt water can be drained from the ice into the ocean. Because the ice moves slowly, and because the currents in the region can keep large volumes of ice moving for many millions of years, this is possible. This process of ice melting and water draining is very interesting for scientists. Through research expeditions such as the Greenland Ice Study, they study this process in depth.

During summers the ice grows very large and this causes the sea ice to thin and extend beyond the Greenland 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 winter months could have the greatest impact on weather conditions due to sea ice changes. Temperature variations are known to vary in this period and a reduction in the thickness of the ice could mean warm 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.

There are some experts who do not believe that a sea ice breakup will have any serious impact on the weather conditions in the North Atlantic. In fact they believe that the changes in climate have always been part of nature. According to them, large melting will occur which will lead to fluctuations of the atmospheric pressure, which will cause slight variations to the temperature. There is also a possibility that precipitation will increase due to melting ice and this will contribute to flood problems in regions with low elevations. 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. The ocean will be able to release the meltwater if the Greenland Ice is broken up into smaller pieces. This will accelerate global warming by increasing the rate at which heat is disappearing from Earth. Satellite images have shown that large amounts meltwater are being released each year from the ice. This is why experts believe the Arctic region is experiencing more severe weather 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.
