Summary
The paper examines the impact of global warming on permafrost of the Arctic. This topic is a part of the broad theme of climate change. Nowadays, global climate changes mostly affect Polar Regions, and particularly the Arctic. The air temperature is growing, the thermohaline structure of the Arctic Ocean is changing, area of sea ice reduces rapidly, permafrost and glaciers continue to ruin.
Changes in ecosystem happen because of three reasons, including the gradient of temperature change, Albedo, and Planck's law. Effects of global warming on the Arctic Ocean are related to the greenhouse effect. It caused melting of sea ice. The upper layer of the ocean becomes greatly desalinated due to the melting of ice and increase in river flow. The area of sea ice is reduced by 80% in the summer months. Average thickness of the drifting ice is reduced by about 42% (Yu, Maykut, and Rothrock), meanwhile the total volume of ice decreases by almost 32%. (Yu, Maykut, and Rothrock).
Air temperature fluctuations penetrate into the rocks. Permafrost is preserved in the below layers, however, at the upper layers the temperature rises almost to zero degrees. Thus, now, the temperature values of permafrost are changing rapidly, endangering the global climate.The consequences of global warming on the Arctic can be expressed in decrease in...
