Polar Changes

In this picture below is a animation of Greenland when 89 percent of it was covered in ice, and then it shows how scientist believe Greenland will look after that 89 percent of ice has melted away into the ocean.

I have read and seen in a book called "The Atlas of CLIMATE CHANGE" that the ice on the cap of Greenland melts each summer at the edge and on the surface. It has melted about 700,000 kilometers over the last thirteen years, between the years of 1992 and 2005. In one year where the ice of Greenland did not melt as much as any other year was in 1992 with an amount of about 250,000 kilometers.

In the picture above it shows the ice of Greenland after a Avalanche moving towards the Atlantic Ocean.

Personal Opinion:

I believe that the ice of Greenland's edge and surface is melting but I cannot agree with the opinion of scientist. They said that the ice cap of Greenland will melt and cover a portion of the United States land, they also predict that it will flood a small percentage of the earth's land area. The reason why I disagree with their predictions is because it would take a very long time to melt all the ice from the surface and edge of Greenland. What the scientist forgot to mention in this verse of the book is that the water cycle cannot be predicted. It saids in the book that the melting area varies, which means that the area that is being melted is unpredictable or is at a up and down scale. Although the trend seems to be heading upward. Also, the amount of water that could be melted from Greenland is unlikely that it will cover platues and mountains blocking the border, but it could surely cover the plains of nearby land area's.
