NASA: Warmest start to a year on record
Although New England experienced a bitterly cold winter, this season was the warmest for the rest of the planet. According to NASA, the past three months have been the warmest start to a year on record. Since the 1940s there has been a steady rise in temperatures between January and March.
Chief Meteorologist Joe Joyce explains the warm water that drove down the west coast of North America caused this year's historic California drought and led the east coast to experience an extra snowy and cold winter.
