Question: How have glaciers changed over time and how do we know? Time-lapse of Earth's glaciers over 48 years Today, scientists study the change of ice mass around the world using satellites high above our heads. We should be grateful for the availability of these satellites to continuously...

Glaciers form when snow accumulates to great depth, and is transformed through the effects of pressure to form ice, which then creeps slowly down slope, at rates which are typically measured in tens to hundreds of meters per year. The fastest moving glacier on Earth is the outlet glacier ...
“That’s a very powerful effect. If that’s the reality in nature, then it’s quite serious.” The newly discovered bubble effect could explain some of that extra melting, says Mathieu Morlighem, a scientist. “It’s improving our understanding, but it’s not painting a darker picture ...
«The observed glaciers currently lose between half a metre and one metre of its ice thickness every year – this is two to three times more than the corresponding average of the 20th century», explains Michael Zemp, Director of the World Glacier Monitoring Service and lead author of the...
If the amount of glacial ice formation in the zone of accumulation equals the amount of melting in the zone of wastage, then the glacier does not advance or retreat. While the ice within the glacier continues to flow away form the source toward the terminus, the toe of the glacier will ...

repeat satellite images are detailed enough that computer algorithms can track the movement of individual features visible on the glacier surface. It is then a simple matter to calculate the velocity field—the velocity of the ice at all locations on the glacier. This is important, because an in...
