Brent Minchew, a geophysicist at Caltech and chief scientist with the Arête Glacier Initiative, describes his research into how to stop that from happening. Cape Cod got hit hard in the blizzard, and our colleagues at WCAI were put to the test to keep the station on the air and delivering critical updates. Morning Edition host Sam Houghton recounts how he slept at the station for days and kept in on the air, until snow and fallen trees reopened roads to CAI's broadcast center. (Did we mention he also had Norovirus?) And out monthly chat with astrophysicist Anjali Tripathi looks at really cold and windy places in outer space.---------Have something you’re curious about?

And librarians from the GBH Archives plow through (ahem...) decades of GBH tape to share gems from wintry television and radio from years past.
