A new study shows that the ice at the bottoms of submerged glaciers could be melting 100 times faster than anyone thought.
Glaciers are essentially giant rivers of ice that are formed over eons as fallen snow is compressed into layers of ice. Glaciers are found on about 10 percent of Earth's land area, with most of them found in the Arctic and Antarctica regions, but some occurring high up on mountains, even in tropical areas. Glacial ice makes up the ice sheets that cover Antarctica and Greenland, with glaciers flowing out to sea, where their ends float on the water as ice shelves. Eventually pieces of the ice shelves break off, or calve, to form icebergs. The movement of glaciers scours the underlying rock, and a glacier's movement can be affected by climate change, with worries that global warming could cause substantial glacial melt and impact global sea levels.

"We know what's happening and what needs to be done," the haunting letter to the future reads. "Only you know if we did it."
Hidden beneath Greenland’s Ice Sheet like an enormous necklace of sparkly blue and oddly shaped beads, scientists have discovered 56 previously unknown and gem-like lakes.
Researchers have discovered the first-ever water sample dating to the end of Earth's last ice age, 20,000 years ago.
There's more nuclear fallout trapped in the world's glaciers than anywhere besides disaster sites like Chernobyl, new research finds.
Even if humans manage to prevent further global warming, the glaciers will still lose half their volume by 2050.
The Quaternary period has seen a lot of temperature changes, but none as quick as man-made climate change.
The breathtaking sound and sight of waters that cascade off of steep cliffs, may be self-made productions.
There's a giant void hiding under the Antarctic ice, and it's growing larger and more menacing by the day, a new study using satellite data finds.
As the ice caps on Baffin Island shrink, the landscape beneath is seeing the light of day for the first time in perhaps 120,000 years. Here’s a look at the stark and humbling beauty.
