Big snowstorms and cold air swept across northern in the first week of November.At the same time，a global（全球的） meeting on climate（氣候） change was held in Glasgow，Scotland.There，leaders from around the world tried to deal with global warming
    Why are we experiencing such a cold winter on a warming planet？The cold winter and global warming，two seemingly opposite facts，are not contradictory.Global warming does not happen evenly （均衡地） on Earth，and it causes more extreme（極端的）heat and cold，Zhou said.
   Because of the warming climate，China has seen a growing temperature in winter.It has increased by 0.41℃ every 10 years since 1961.But in some cases，the country has also seen extreme cold - for example，the icy weather in early 2008.
   Global warming has affected the local weather through sea-air or land-air interaction（相互作用）.For example，in October，La Nina affected China.It is caused by strong winds above the Pacific Ocean.It brought more cold air to China.Another reason for the cold weather is the warming Arctic，according to BBC.It is warming almost three times as fast as any other place on Earth.
   Will this winter be much colder？The official forecast （預(yù)報）said a cold winter is likely.Northern China will probably see more snow than average，and Southern China less rainfall than average.
