Archaeologists have collected more than 2,000 artifacts dropped by ancient reindeer hunters in Norway's icy mountains.
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. For the latest news on glacier research and stunning views of these rivers of ice, see below.
As climate change melts the ice patches of Norway, artifacts from the past 6,000 years are being exposed.
The giant ice wall that protects the Seven Kingdoms from the White Walkers is physically unrealistic, glaciologists say.
In what appears to be a historic first, a chicken sandwich was successfully carried to the edge of space today aboard a high-altitude balloon.
Thanks to rising temperatures, glaciers in Greenland are melting faster than scientists previously thought — and a new NASA video shows how researchers are tracking the feet per day of changes.
The Barents Sea near Svalbard is dotted with seafloor craters created about 11,600 years ago by methane hydrate eruptions.
Over the past 50 years, 39 of the park's glaciers have shrunk dramatically, some by as much as 85 percent.
A team of scientists has put together photographic "proof" of climate change, revealing time-lapse photo couplets, or before/after images, of retreating glaciers.
The last ice age led to the rise of the woolly mammoth and the vast expansion of glaciers, but it's just one of many that have chilled Earth throughout the planet's 4.5-billion-year history.
A chunk of ice covering an area larger than the state of Rhode Island is about to snap off Antarctica's Larsen C Ice Shelf.
Snow plays an important role in Earth's water cycle, and NASA has launched a new initiative to investigate snow and its relationship to readily available liquid water.
