ice field

In order for the Erebus to make its way through the thickest ice fields, the British Admiralty equipped the vessel with a fifteen-ton, twenty-five horsepower railroad locomotive engine.

After that, near-surface temperatures will rise sharply, speeding up melting across the world's ice fields.

Waist-deep snow, ice fields, avalanches and the risk of hypothermia and frostbite make the mountain a far riskier proposition.

They monitored floods, measured continental and ocean-surface temperatures, traced the movement of ice fields, and sensed the ground buckle during earthquakes.

They warn it may now be too late to save many of the alpine ice fields, even if climate targets are met.
