Arctic sea ice cover hits its worst record for 2018

• The ice cover in arctic reached its lowest on September  2018,and it gets worsened day by day.
• With an ice cover of 4.59 million sq km, 2018 is tied with 2008 and 2010 for the sixth lowest summertime ice cover.
• The growth and decay of ice capping in Arctic ocean depends on several reasons.
• It thickens during fall and winter and thin during summer and spring.
• This affects earth's weather patterns and ocean circulation.
• The scientist in NASA says that cover is relatively higher that what it was in 2012, but relatively lower than in 1970s , 80s, and 90s.
