Video - NASA satellite witnesses Arctic ice sheet being torn to shreds.(Yahoo).The fracturing started in late January, as a warm-weather system over Alaska fed an ocean current known as the Beaufort Gyre. This strengthened current picked away at the southwest corner of the ice sheet until a massive crack opened up north of central Alaska (at about 3 secs into the video), and then another crack, apparently around 1,000 kms long, opens up in late February (at around 30 sec in the video), leading to the collapse of the rest of the ice sheet, all the way east to Bank Island.

“It took just seven days for the fractures to progress across the entire area from west to east,” Trudy Wohlleben, senior ice forecaster at the Canadian Ice Service, told the National Post.
According to Walt Meier, a research scientist with the National Snow & Ice Data Center (NSIDC), it's not unusual for this area to experience fracturing events. However, what is unusual is the extent of the fracturing and the scale (both length and width) of the cracks being seen, and it's the age of the ice that's being blamed.Read the full story here.
