Iceberg! Straight Ahead! (well, really far North, actually).

Peterman glacier,
the source of the island

On Thursday, August 5th, a massive glacier island cleaved itself off of Greenland, that not-so-green island way up North. It was about 100 square miles in size and is the largest glacier in the Arctic to have come loose since the '60s! It's not really known yet if the glacier will catch on land and freeze back in this Winter, or if currents will push the island through the obstacles in into the main ocean. If it did, it would likely interfere with shipping!
