ILULISSAT, GREENLAND-- Here’s your bit o’ science jargon for the day: cryoconite. It’s a word I encountered in the Dry Valleys of Antarctica seven years… {Read More »}

ILULISSAT, GREENLAND-- When scientists try to discover why a large glacier in Greenland suddenly speeds up, they look for all kinds of clues, including the sudden flood of water to the base of the glacier when a giant melt lake cracks the ice open. In this video, we ask scientist Ian Joughin about the significance of these floods... {Read More »}

ILULISSAT, GREENLAND-- The Exploratorium crew has moved to Ilulissat, a beautiful town 250 kilometers above the Arctic Circle on the west coast of Greenland. This is a gathering place for glaciologists because it’s close to the one of the world’s fastest-moving and most productive glaciers, the Jakobshavn glacier... {Read More »}
