Traveling just over 6 mph would hardly break any speed record. But for a glacier, it is a pace that is considered unprecedented.
In fact, the summer speed of Greenland’s Jakobshavn Glacier, according to a new study published by The Cryosphere, has more than quadrupled its summer speed since the 1990s. The study claims that the glacier, which is believed to have spawned the iceberg that sunk the Titanic, set speed records faster than any previously recorded for glaciers or ice streams in both Greenland or Antarctica.
Melting glaciers mean more water to explore and profit from in the Arctic, but it can also mean danger for mariners.
