NASA satellite images show 2 cracks crossing the Antarctic ice shelf, which have all chances to break off and make a 1700-kilometer iceberg.

The crack, known as the" Halloween crack", was first seen in October 2016 and spreads to the East. He must meet another 1 crack, which was measured in the direction of 35 years, but now accelerates to the North at a speed of 2.5 miles per year.

As soon as this happens, the shelf will release an iceberg within 660 square miles (1,700 square kilometers), more than all areas of London combined (607 square miles) and 2 times more than new York city. This will probably happen in the direction of a few months, and it will be the biggest iceberg to separate from the main ice shelf since 1915.

Depending on where the cracks connect, the strength of the entire shelf has the potential to be put at risk, Joe McGregor, a glaciologist at NASA Goddard's galactic flight Center, told the earth Observatory: "in the event that [the cracks] connect upwards in the direction (South) of the cold streams of McDonald, it is likely that the cold shelf itself will become destabilized."

The long-term future of Antarctic ice shelves will have a significant impact on the increasing importance of the sea worldwide. The report, posted by scientists last year, tells that the Antarctic ice is melting at a record pace, accelerating three times over the past 5 years, and now gives a serious danger to coastal settlements.

In the event that there is no significant reduction in greenhouse gas emissions, scientists are talking, in fact, that the melting ice of Antarctica is obliged to add more than 25 cm to the total global increase in the value of the sea by 2070.
