A decade long period of stability for Arctic's summer sea ice?

The large number of climate change scientists agree that the Arctic ice will eventually disappear completely during summer months if climate change continues at current pace. Some believe such scenario will very likely happen before the year 2050.

The several different studies have showed that in the last thirty years Arctic summer ice has shrunk by more than a third driven by unusual warm climate which cannot be only explained by natural causes.

One of the most interesting recent studies about the melting of Arctic ice comes from the National Center for Atmospheric Research (NCAR). According to this study the Arctic ice may temporarily stabilize or even somewhat expand at times over the next few decades.

This was a rather interesting conclusion and the scientists were somewhat surprised by the results of computer simulations which showed a temporary stop to the loss of the Arctic ice.

The results of computer simulations showed that Arctic could well see a 10-year period of stable ice or even a slight increase in the expansion of the ice.

However, long-term speaking we are still in for a total loss of Arctic's summer sea ice. One of the leading NCAR scientist Jennifer Kay said that "when you start looking at longer-term trends, 50 or 60 years, there's no escaping the loss of Arctic's ice in the summer."
