Meteorology has become a doomsday science. Bomb cyclone? Polar vortex? What happened to scattered flurries?
“When things get very cold, things change,” John Jarrell, president of Materials Science Associates in Rhode Island. “The nature of materials change, and the systems we’ve designed to operate at normal temperatures are stressed.”
