It's all so confusing: Over 33,000 Manhattans of Arctic sea ice is a "small patch" that "nobody's going to care" about, but two Manhattans is a "large", "massive", "staggering" amount of ice

'Astonishing' Arctic Ice Melt Sets New Record : NPR

"It doesn't take a scientist to look at what's happened to the Arctic sea ice to know that something really huge is happening in the climate system," says Jennifer Francis at Rutgers University.

Think of those slow-moving snow storms that buried the East Coast a couple of winters ago. She expects some extreme weather this coming winter, though there's no telling whether it will hit us or someone on the other side of the globe.   [Jennifer:  In what year did we ever have a Northern Hemisphere winter that featured no extreme weather?]
...[Scambos] "Nobody's going to care that there's a small patch of say 1 or 2 million square kilometers in the Arctic," he says, "because it will be off to one side."

Yet, even in extremely warm years like this one, ice is still a force to contend with. Some of the key navigational passages never did open up this summer. And a chunk of ice 30 miles long is heading toward Shell Oil's drilling site in the Arctic Ocean. That has forced the company to move its rig out of the way, just a day after it started drilling.

Flashback: Massive Iceberg Breaks Loose From Greenland’s Petermann Glacier

An iceberg twice the size of Manhattan has broken off of one of Greenland’s largest glaciers in a move that has been predicted for almost a year.
...the newly formed iceberg measures a staggering 46 square miles, according to ABC News.

Although the newest iceberg is massive, the same glacier spawned an iceberg twice its size in 2010. While researchers are suspecting that global warming is to blame for the massive loss of arctic ice, they are unable to conclusively prove the theory.

While several of Greenland’s southern glaciers are melting more rapidly than before, people like government scientist Ted Scambos are acknowledging that this latest break brings large ice loss much farther north.
