Also, the hard permafrost that originally prevented beaches from eroding during violent storms is now melting. Roads and utility poles are collapsing as the ground around and under them warms and soften. Now, the thawing permafrost is causing a number of problems for people living in Alaska. ![]() ![]() Much of the land in Alaska used to be permanently frozen or frozen for most of the year. It may be even more in the near future, as some scientists predict that the average world temperature could go up 4 to 7☌ by the year 2100.Īnother problem facing Alaska is its thawing permafrost. Presently, an estimated 100 cubic kilometers of ice is disappearing from Alaskan glaciers every year. Additionally, the average winter temperature has increased by over 6☌. Since the 19605, the average year-round temperature has increased by almost 3☌. This diminishing seems mainly due to the increase in global temperatures. That is an area of land larger than Ireland!Īccording to a recent report by the US Geological Survey, ninety-nine percent of Alaska's glaciers are either retreating or diminishing. These glaciers account for about 75,000 square kilometers, or five percent, of the state’s area. The state has more than 100,000 glaciers. How can a whole state be disappearing? The problem is that Alaska’s glaciers are melting. It is estimated that since the 19505, as much as fifteen percent of Alaska's land area has disappeared. Read the following passage and mark the letter A, B, C, or D to indicate the correct answer to each of the question.Īlaska is disappearing slowly, but surely.
