In this image obtained from NASA, the space agency's DC-8 flies over the Pine Island Glacier Ice Shelf on October 14, 2011, studying the crack spreading across the ice shelf. The massive crack is growing wider in the Antarctic ice sheet and could break apart in the coming months, forming an iceberg the size of Brazil, NASA scientists warned on Novermber 3, 2011. The crack in western Antarctica stretches for at least 18 miles (30 kilometers) and runs 165 feet (50 meters) deep. The rift is widening at a rate of 6.5 feet (two meters) per day, said NASA project scientist Michael Studinger. = RESTRICTED TO EDITORIAL USE - MANDATORY CREDIT

Znanstvenici vjeruju kako je odvajanje ledenjaka dio prirodnog procesa, a ne posljedica globalnog zagrijavanja

Velika pukotina na Antarktiku postaje sve veća, a kroz nekoliko mjeseci bi mogla dovesti do odvajanja komada leda veličine New Yorka, upozorila je NASA , javlja AFP.

Pukotina na glečeru Pine Island proteže se u dužinu od 30 kilometara, a duboka je 50 metara. Širi se brzinom od dva metra dnevno, a kada sekonačno odvoji od Antarktika nastat će ledenjak površine 880 kvadratnih kilometara. Ovaj proces nije rezultat globalnog zatopljenja, jer znanstvenici očekuju nastanak ledenjaka otprilike iste veličine, čime bi se završio ciklus otapanja i smrzavanja.

- Ovo su ciklički događaji. Posljednji značajan se dogodio 2001. godine, tako da smo i očekivali da se nešto slično dogodi - objasnio je Michael Studinger iz NASA-e.
