Melting of the Permafrost in the Arctic Accelerates Global Warming

As a corollary effect of global warming, permafrost in the Arctic is gradually melting causing the release of more greenhouse gases in the form of carbon dioxide and methane into the atmosphere. These gases are powerful heat-trapping gases which accelerates the alarming climate change phenomenon. The only consolation according to Prof. Dave McGuire of the U.S. Geological Survey and an ecology professor at the University of Alaska is that this occurrence is happening slowly.

In a recent scientific study conducted, the temperature of the permafrost or cryotic soil in the Arctic has already risen from 18 degrees to 28 degrees Fahrenheit. The statistics disclosed that the increase in the temperature of the permafrost accounts for around 10 percent of global warming which is roughly the same amount as that being contributed by tropical deforestation.

Prof. McGuire in his competent analysis disclosed that the estimates that they came up with suggest that throughout the rest of this century, it could be on the order of the magnitude of what tropical deforestation currently affects the global carbon cycle.

17 scientists from around the world and who belong to the Permafrost Carbon Network, a group studying climate change in the Arctic region, are responsible for the conduct of the scientific study on the thawing of the permafrost or cryotic soil in the Arctic Region. The results of their study is contained in a review entitled Climate Change and the Permafrost Carbon Feedback and was published in the journal “Nature”.
