Siberia
Large expanses of tundra permafrost are melting. In some regions the rate of thawing of the upper ground is nearly 8 inches (20 cm) per year. Thawing permafrost has already damaged 300 buildings in the cities of Norilsk and Yakutsk. In Yakutsk, the average temperature of the permanently frozen ground has warmed by 2.7 °F (1.5°C) during the past 30 years.
