According to a scientific survey, large areas of Arctic summer sea ice have melted down but this melting is considered to be lower than the normal or usual melt down. It was figured out that the extent of the Arctic sea ice was 1.79 million square miles at the end of the annual summer melt, which was 610,000 square miles below the 1981-2010 average for the same date and was considered as the eighth lowest year in the past 38-years of satellite record.
Scientists from the National Snow and Ice Data Centre (NSIDC) informed that the rate of ice loss is quite slower this summer this might have occurred due to the persistent pattern of low pressure at sea level present over the central Arctic Ocean. NSIDC also revealed that this year ice cover was 193,000 square miles above 2016’s minimum, at its lowest extent.
Actually, the Arctic sea ice melts due to the warmer temperatures of summer and this melting slows down during September and after that gain ice formation starts during the months of winter. But many Conservationists have warned that in those last 30 years, the minimum sea ice extent during summer has been reduced to an area equivalent to about quarter the size of Europe and also predicted that the Arctic region could become virtually ice-free in summer in upcoming years.
Rod Downie, head of polar programs at environmental charity WWF, told that the loss of Arctic sea ice can be seen clearly from space and for this and all this has happened due to climate change for which human beings are mostly responsible. He said that this problem is not good for the Arctic people who rely upon sea ice to carry forward their traditional living style and also many other people across the globe who are dependent on Stable climate.
He added that Arctic is changing and the sea ice cover is declining. So, it becomes important that several precautionary measures should be taken to tackle climate change and save the Arctic ice which is very important for the stability of Earth’s climate.
