While NYC experienced torrential downpours today, an iceberg twice the size of Manhattan broke off from Greenland's Petermann Glacier, Reuters is reporting. 

The Petermann Glacier is located in Northwest Greenland and measures a massive 43 mi long and 9.3 mil wide. Today's calve is the second break in two years. In 2010, a smaller iceberg broke off and floated into the North Atlantic shipping lanes and endanger oil rigs.

The break was spotted by NASA's Aqua satellite, which passes over the North Pole several times, and was reported by Trudy Wohlleben of the Canadian Ice Service.

Despite its massive size, scientists don't believe the iceberg will cause any damage or adversley effect the environment around it:

The movement of this huge amount of ice into open water will have no immediate impact on sea levels, since this ice was already part of an ice shelf that was attached to land but extended over water, just as a melting ice cube in a glass of water does not raise the level of water in the glass.
