The Arctic Ocean is Becoming More Like the Atlantic Ocean

A few days ago, I read an article on the website of the American association for the advancement of science. It was talking about changes in the Arctic Ocean. Since 2002, a team of scientists from the University of Alaska Fairbanks, led by Igor V. Polyakov, is making observations in this part of the Earth. The researchers set buoys to collect data during the different seasons and they compared them with those they take with satellites. They notice that the Arctic Ocean starts to have more common features with the Atlantic Ocean. Effectively, the ice covering the ocean is melting and the different layers of water are mixing, making the temperature more equal. Those changes could affect the water phenomena and the ecosystems we can found there. The full article can be found with this link:
Personally, I think those changes could cause a lot of problems in the future. First, there are different varieties of fishes and aquatic plants in the Arctic Ocean and an alteration of their habitat could affect gravely many species. Also, the melting of ices increase the amount of water in all the oceans. This could become a problem for towns located at ocean level. It could flood those cities and destroyed houses of a lot people. It could destroyed parts of many cultures. Moreover, Arctic glaciers are an important source of freshwater on the Earth. When they melt, the water they contained is mixed in the ocean and it reduce the proportion of freshwater. Those consequences that could result of the changes in the Arctic Ocean make the researches of Igor V. Polyakov really important. With his discoveries, maybe some scientists will be able to find solutions to the problems that could appear.
