A Massive Glacial Crack Just Made an Iceberg as Big as New York City

A massive crack in the Pine Island glacier (PIG) in Antarctica has created a massive iceberg—which is as big as New York City.

While cracks in glaciers are common—PIG cracked in 2001 and 2007—this one took longer to propagate, which meant that more ice has accumulated by the time giant iceberg broke away. The German Earth-observation satellite TerraSAR-X confirmed the break on Monday using radar imaging. Now, the 30km-wide iceberg will drift into the Southern Ocean. [New Scientist]
