Not something you see everyday — a snow-covered desert. The Taklimakan Desert in western China, the country’s largest desert, was covered with snow after a storm swept through the area in late December 2012 and continued into early January (the area also received snow in 2008). The cold wave hit different parts of China including Xinjiang Uygur Autonomous Region, Inner Mongolia Autonomous Region, north China and northeast China. Could it be attributed to the melting of arctic sea ice pushing colder weather south? This seems a question worth further exploration. Clearly, extreme weather events of this kind are not limited to certain geographic areas as last year’s cold snap in Europe also demonstrated.
