Spring, Finally; Deportation Policy; Dangerous Conspiracies; Career Restarts

Flowers bloom in spring along the Hudson River in Lower Manhattan.

Today is the first day of spring! A meteorologist explains the vernal equinox and the climatology behind the change in seasons. Plus: a new VICE documentary on deportation; Harvard law professor, former White House advisor and author Cass Sunstein talks about his new collection of essays Conspiracy Theories and Other Dangerous Ideas; and a call-in for women who have successfully returned to work after taking years off to stay home with children or aging parents.
