New research provides insight into ice sheet behavior
A new study published this week takes scientists a step further in their quest to understand how Antarctica's vast glaciers will contribute to future sea-level rise. view more (2009-07-21)
Antarctica glacier retreat creates new carbon dioxide store
Large blooms of tiny marine plants called phytoplankton are flourishing in areas of open water left exposed by the recent and rapid melting of ice shelves and glaciers around the Antarctic Peninsula. view more (2009-11-10)
Researcher discovers hybrid speciation in the Sierra Nevada
University of Nevada, Reno researcher Matthew Forister is among a group of scientists that have documented an unusual type of speciation in the Sierra Nevada, including a hybrid species of butterfly that can trace its lineage as far back as almost a half a million years ago. view more (2007-01-29)
Researchers study how ice melts in contact with soil
A team of scientists from the Max Planck Institute for Metals Research in Stuttgart (Germany) and the ESRF in France has studied how ice starts to melt at temperatures as low as - 17°C. This can occur when ice is in contact with SiO2, a material commonly found in soil. Below the melting temperature of ice, a layer much denser than 'regular'... view more... (2004-06-15)
Mountain climate change trends could predict water resources
New research into climate change in the Western Himalaya and the surrounding Karakoram and Hindu Kush mountains could explain why many glaciers there are growing and not melting. view more (2006-08-25)
U. of Colorado study shows desert droughts lead to earlier annual mountain snow loss
A new study spearheaded by the University of Colorado at Boulder's National Snow and Ice Data Center indicates wind-blown dust from drought-stricken and disturbed lands in the Southwest can shorten the duration of mountain snow cover hundreds of miles away in the Colorado mountains by roughly a month. view more (2007-06-26)
Volcanoes cool the tropics, say researchers
Climate researchers have shown that big volcanic eruptions over the past 450 years have temporarily cooled weather in the tropics-but suggest that such effects may have been masked in the 20th century by rising global temperatures. view more (2009-01-06)
North meets south? Glaciers move together in far-flung regions
Results of a new study add evidence that climate swings in the northern hemisphere over the past 12,000 years have been tightly linked to changes in the tropics. view more (2009-09-25)
Martian Snow Source of Tropical Glaciers, Research Team Reports
Snow is the source of glacial deposits found at the base of the majestic volcanoes and mountains dotting the mid-latitude and tropical regions of Mars. view more (2006-01-20)
HUMIDITY INDUCES MELTING IN TROPICAL-ZONE GLACIERS
On Zongo glacier in Bolivia, situated at between 6000 and 4900 m elevation on the Huayna Potosi massif, 30 km from La Paz, scientists have observed that the runoff stream, induced by ice melting, showed a discharge rate two or three times lower during the dry season (May to August at this latitude) than that in the wet season (November to... view more...

Himalayan glacier melting observed from space
The Himalaya, the "Roof of the World", source of the seven largest rivers of Asia are, like other mountain chains, suffering the effects of global warming. view more (2007-03-28)
When it comes to sea level changing glaciers, new NASA technique measures up
A NASA-led research team has used satellite data to make the most precise measurements to date of changes in the mass of mountain glaciers in the Gulf of Alaska, a region expected to be a significant contributor to global sea level rise over the next 50-100 years. view more (2008-11-07)
Freeze-dried mats of microbes awaken in Antarctic streambed, says U. of Colorado study
An experiment in a dry Antarctic stream channel has shown that a carpet of freeze-dried microbes that lay dormant for two decades sprang to life one day after water was diverted into it, said a University of Colorado at Boulder researcher. view more (2005-08-10)
As Andean glacier retreats, tiny life forms swiftly move in, CU-Boulder study shows
A University of Colorado at Boulder team working at 16,400 feet in the Peruvian Andes has discovered how barren soils uncovered by retreating glacier ice can swiftly establish a thriving community of microbes, setting the table for lichens, mosses and alpine plants. view more (2008-09-09)
Ice Sheets Can Retreat
Modern glaciers, such as those making up the Greenland and Antarctic ice sheets, are capable of undergoing periods of rapid shrinkage or retreat, according to new findings by paleoclimatologists at the University at Buffalo. view more (2009-06-22)
NASA mission checks health of Greenland's ice sheet and glaciers
A NASA-led research team has returned from Greenland after an annual three-week mission to check the health of its glaciers and ice sheet. About 82 percent of Greenland is made up of a giant ice sheet. view more (2007-05-31)
Researchers warm up to melt's role in Greenland ice loss
In July 2006, researchers afloat in a dinghy on a mile-wide glacial lake in Greenland studied features of the lake and ice 40 feet below. Ten days later the entire contents of the lake emptied through a crack in the ice with a force equaling the pummeling water of Niagara Falls. The entire process only took 90 minutes. view more (2008-04-21)
Britain populated rapidly after ice age
Research News from the Journal of Quaternary Science 13 October 2003: New data show that humans responded rapidly to climate change and moved into Britain en masse almost as soon as the last ice age ended. This challenges the previously held view that repopulation was a slow process led by a few pioneering explorers. Recent innovations have... view more... (2003-10-13)
New Tibetan ice cores missing A-bomb blast
Ice cores drilled last year from the summit of a Himalayan ice field lack the distinctive radioactive signals that mark virtually every other ice core retrieved worldwide. That missing radioactivity, originating as fallout from atmospheric nuclear tests during the 1950s and 1960s, routinely provides researchers with a benchmark against which they... view more...

Arctic lake sediments show warming, unique ecological changes in recent decades
An analysis of sediment cores indicates that biological and chemical changes occurring at a remote Arctic lake are unprecedented over the past 200,000 years and likely are the result of human-caused climate change, according to a new study led by the University of Colorado at Boulder. view more (2009-10-20)
