<![CDATA[Seth Back On Crack]]>If an iceberg calves in the Arctic, and no neurotic leftie sees it in a satellite image, does it still cause the world to end?

WASHINGTON — 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.

That is how glaciers work, Mr. Nitwit. The snow accumulates in the interior, turns into ice, flows to the sea, cracks, breaks off and floats away.

One hundred years ago a large iceberg from Greenland sank the Titanic, but no mentally deficient lefties were there to blame it on your SUV.
