According to this article, the recent rate of permafrost melting is "unbelievable" according to Professor Vladimir Romanovsky. Over the past four years, permafrost temperatures have consistently risen. Many scientist worry that the melting of permafrost is going to release methane and other greenhouse gasses stuck in the ice. It is expected that the permafrost in parts of Alaska will thaw out by 2070. There is worry that this might not only cause a release greenhouse gases but also create massive sinkholes.
This is important because it shows what can happen as a result of global warming. The melting of the permafrost can result in serious changes. Due to global warming, these changes may occur sooner than previously expected.
