Massive Ice Shelf Drifts Into Arctic Ocean

In environmental news, a 41-square-mile ice shelf that had jutted into the Arctic Ocean for 3,000 years has broken away. Scientists say the ice shelf drifted away because of sharply warmer temperatures in the Arctic region.

Meanwhile no snowfall was recorded in Central Park in New York last month. It marks the first December without snow in the park since 1877.
