The birth of an iceberg comes with its own characteristic sound, according to new research.
A mysterious crater discovered in East Antarctica last month likely formed beneath a leaky meltwater lake.
Melting glaciers pose another threat beyond sea level rise. They will dump massive amounts of organic carbon into the world's oceans, altering ecosystems.
Greenland didn't always have glaciers, reports a new study that pins the region's ice-cold features on plate tectonics and a shift in the Earth's tilt.
It's not only glaciers that are sending water rushing into the sea; surface sea ice is contributing more and more meltwater.
Scientists suspect Antarctica's shrinking glaciers are melting from the bottom up, and a fleet of robot ocean gliders may help explain why.
Glaciers worldwide are melting due to human factors, such as greenhouse-gas emissions and aerosols, a new study suggests.
