As the global temperature is rising, the Arctic sea ice has shrunk to its second-lowest level on record last week. Puza Snigdha reports.
The U.S. scientists have reported that Arctic sea ice has reached its second lowest level in four decades which is documented since 1979. Before this year the ice melted in 2012.
Arctic sea ice has seasonal cycle. Each Summer, sea ice is frozen ocean water melts and reforms in winter.
According to the Satellites record, Arctic sea ice extent fell to 3.74m square kilometers on 15th September.
“The year 2020 will stand as an exclamation point on the downward trend in Arctic sea ice extent,” said Mark Serreze, director of the National Snow and Ice Data Center.
The ice cover was about 2.7 million square kilometres bigger than current summer levels, in 1980s.
Studies show that the warming of the Arctic and the liquefying of ocean ice change climate further south by modifying the fly stream and different waves that move climate frameworks.
