Welcome to CoreFacts, where we're always short on time, but big on science. I'm Steve Sobieszczyk. Today's question is a good one.

Is glacier ice colder than regular ice?

No - indeed, all of the physical, thermal and electrical properties of "regular icebox ice" and glacier ice are identical: density, viscosity, heat of fusion, latent heat, heat capacity, thermal conductivity, and absorption. The few small differences in characteristics are solely due to grain size differences. It's worth noting that high pressure forms of ice with different properties have been produced in laboratory experiments, but none occur naturally on earth, not even at the base of the Antarctic or Greenland ice sheets.
