Greenland lost some more land

WASHINGTON (AP) — An iceberg twice the size of Manhattan tore off one of Greenland's largest glaciers, illustrating another dramatic change to the warming island.

For several years, scientists had been watching a long crack near the tip of the northerly Petermann Glacier. On Monday, NASA satellites showed it had broken completely, freeing an iceberg measuring 46 square miles.

A massive ice sheet covers about four-fifths of Greenland. Petermann Glacier is mostly on land, but a segment sticks out over water like a frozen tongue, and that's where the break occurred.

The same glacier spawned an iceberg twice that size two years ago. Together, the breaks made a large change that's got the attention of researchers.

"It's dramatic. It's disturbing," said University of Delaware professor Andreas Muenchow, who was one of the first researchers to notice the break. "We have data for 150 years and we see changes that we have not seen before."

"It's one of the manifestations that Greenland is changing very fast," he said.

Nkemdiche makes his pick ... FOOTBALL

Many who follow recruiting were shocked when prized defensive end Robert Nkemdiche of Loganville (Ga.) Grayson, the country's No. 1 overall prospect, committed to Clemson on Thursday. Although Nkemdiche consistently listed the Tigers among his favorites, few ever seemed to give the Tigers much of a shot.

Alabama, long considered the leader, not only had tradition and a history of producing NFL talent on its side, but a Crimson Tide alum - Mickey Conn - coaching his team.

Robert Nkemdiche followed his friend David Kamara to Clemson.

Ole Miss, where Nkemdiche's brother, Denzel, is a defensive back, also seemed like a possible destination. So did LSU, a school that Nkemdiche raved about at length after visiting earlier this year.

Recently, there also was chatter about Georgia, which hired Daryl Jones, a Grayson assistant during Nkemdiche's freshman year, as its Director of On-Campus Recruiting, and Mississippi State, which signed former Grayson quarterback Nick Schuessler, whom Nkemdiche has lived with, in February.

Meantime, Clemson got very little buzz.

That changed Wednesday night when defensive back David Kamara of Grayson, one of Nkemdiche's closest friends, announced via Twitter he had verbally committed to the Tigers. Kamara has said for months he and Nkemdiche intended to play together in college.

Turns out, he was right.
