ANSWER: 100,000
Explanation:
Arctic is on track to be free of ice this year for the first time in more than 100,000 years, scientists say. Provision data provided by the US National Snow and Ice Data Centre indicated there were over 11.1 million sq km of sea ice on June 1 this year, as against average for the past 30 years of nearly 12.7 million sq km. This difference of more than 1.5 million square kilometre is about the size of six UKs. - Head of the Polar Ocean Physics Group, Cambridge University, Professor Peter Wadhams said that the latest figures bore out the controversial predictions made earlier.
- Professor Peter Wadhams has also predicted that Arctic ice may well disappear and have an area of less than one million sq km for September this year.
- Though the ice doesn’t completely disappear, that is, have an area of less than one million sq km for September of this year.
- Though the ice does not completely disappear, it is very likely this will be a record low year.
- It could go down to a million this year. Ice free means that the central part of the Arctic and North Pole is ice free.
- Remaining ice within the Arctic Circle would be trapped among myriad of islands along the north coast of Canada
