Snowstorms gave parts of the South a White Christmas, but for most of the East Coast, the blizzards only began on Sunday morning. North Carolina, Virginia and Maryland have all declared states of emergency. New York, Eastern Pennsylvania, and New Jersey suffered through white-out conditions yesterday, stifling travel the day after Christmas. This morning rail service up and down the coast has been canceled, along with thousands of flights, leaving huge numbers of travelers stranded.
In fact, much of the U.S. and Western Europe have already suffered through a spate of snowstorms this winter ? and it's only December. Michael Allaby, author of the book series "Dangerous Weather," joins us to discuss the impact of blizzards across the country and the world.
