Understanding the ebb and flow of Peru’s glacial past

Many thousands of years ago, as the world slowly began to thaw at the end of the last ice age, the landscapes of southern...

Ice cores reveal a slow decline in atmospheric oxygen over the...

Princeton University researchers have compiled 30 years of data to construct the first ice core-based record of atmospheric oxygen concentrations spanning the past 800,000...

Insights into biogeochemical cycles based on glacial meltwater chemistry

Ph.D. student Lukasz Stachnik received funding from the Arctic Field Grant (AFG) in 2012 and 2013. He has, together with colleagues from HiSF and...

Greenland ice is melting 7 percent faster than previously thought

The same hotspot in Earth's mantle that feeds Iceland's active volcanoes has been playing a trick on the scientists who are trying to measure...

Ocean warming primary cause of Antarctic Peninsula glacier retreat

A new study has found for the first time that ocean warming is the primary cause of retreat of glaciers on the western Antarctic...

Massive landslide detected in Glacier Bay’s fragile mountains

A 4,000-foot-high mountainside collapsed in Glacier Bay National Park this week in a massive landslide that spread debris for miles across the glacier below....

Cosmopolitan snow algae accelerate melting of Arctic glaciers

The role of red pigmented snow algae in melting Arctic glaciers has been strongly underestimated, suggests a study to be published in Nature Communications...

New research reveals secrets of former subglacial lakes in North America

Researchers at the University of Sheffield have provided a unique glimpse into one of the least understood environments on Earth by revealing for the...

Huge ancient river basin explains location of the world’s fastest flowing...

An ancient basin hidden beneath the Greenland ice sheet, discovered by researchers at the University of Bristol, may help explain the location, size and...

Scientists predict extensive ice loss from huge Antarctic glacier

Current rates of climate change could trigger instability in a major Antarctic glacier, ultimately leading to more than 2m of sea-level rise. This is the...

Researchers discover fate of melting glacial ice in Greenland

Over the past several decades, scientists have observed a significant increase in the melting of glacial land ice on the island of Greenland, spurring...

Ice loss accelerating in Greenland’s coastal glaciers, study finds

Surface meltwater draining through and underneath Greenland's tidewater glaciers is accelerating their loss of ice mass, according to a Dartmouth study that sheds light...

Into the belly of a glacier

Dropping into an ice cave is like entering another world: There's no wind, no ambient sound, and no discernible smell—unless you're eating a peanut...

Geologic formation could hold clues to melting glacier floodwaters

Geologists investigating an unusual landform in the Wabash River Valley in southern Illinois expected to find seismic origins, but instead found the aftermath of...

Analysis exposes faster disintegration of major Greenland glacier

A study appearing in Science magazine today shows a vast ice sheet in northeast Greenland has begun a phase of speeded-up ice loss, contributing...

Massive northeast Greenland glacier is rapidly melting

A glacier in northeast Greenland that holds enough water to raise global sea levels by more than 18 inches has come unmoored from a...

Seismic Signals Reveal Changes in Water Release from Glaciers

Tidewater glaciers flow from frigid mountains and ice sheet interiors down through ice-carved valleys and terminate in the sea, within fjords. Beneath the glaciers,...

Scientists find formula for rate of glacial erosion

It's a truism that mathematical relationships are present nearly everywhere in nature, probably more than we realise. The latest place they have turned up...

Substantial Glacier Ice Loss in Central Asia’s Largest Mountain Range

Glaciers in Central Asia experience substantial losses in glacier mass and area. Along the Tien Shan, Central Asia's largest mountain range, glaciers have lost...

Glacial earthquakes may help forecast sea-level rise

It is only recently that scientists learned of the existence of glacial earthquakes–measurable seismic rumblings produced as massive chunks fall off the fronts of...
