Ice lab gets to the core of the climate crisis - Roll Call

LAKEWOOD, Colo. — Princess Elsa isn’t moving. Maybe because she’s inanimate. Or she takes her role in Disney’s movie “Frozen” too literally. The fact she’s a cutout could explain it. 

Or maybe it’s because Elsa, stored in the nation’s premier ice core laboratory, a freezer that holds more than 22,000 meters worth of core samples, lives in a room kept at -36 C. 

“The ice cores are the best record that we have of natural climate change,” Richard Nunn, assistant curator at the National Science Foundation Ice Core Facility, said during a recent visit. “To the best of my knowledge, this is the largest single collection of ice cores in the world.”
