Under the influence of global warming, temperature in the Arctic has increased more significantly than the global average. However, winter extreme cold events in Eurasia including China, have become frequent in recent years. This trend is obviously contrary to global warming. Severe weather with cold surges, ice-snow and frozen rain occurred in southern China in 2008, and the overwhelming “boss-level” cold wave that attacked almost all of China in 2016 caused heavy casualties and property loss. Scholars believe that these events are closely related to the rapid decline of Arctic sea ice.
