Study reveals structure and origins of glacial polish on Yosemite’s rocks

The glaciers that carved Yosemite Valley left highly polished surfaces on many of the region's rock formations. These smooth, shiny surfaces, known as glacial...

Mountain glaciers shrinking across the West

Until recently, glaciers in the United States have been measured in two ways: placing stakes in the snow, as federal scientists have done each...

Rusting fool’s gold in glaciers a sign of increased carbon

Some say the world will end in fire, some in ice. One more reason to hold with those who favor fire: USC scientists have...

Glaciers may have helped warm Earth

It seems counterintuitive, but over the eons, glaciers may have made Earth warmer, according to a Rice University professor. Mark Torres, an assistant professor of...

Mountain glaciers recharge vital aquifers

Small mountain glaciers play a big role in recharging vital aquifers and in keeping rivers flowing during the winter, according to a new study...

Saying goodbye to glaciers

Glaciers around the world are disappearing before our eyes, and the implications for people are wide-ranging and troubling, Twila Moon, a glacier expert at...

Ice cave in Transylvania yields window into region’s past

Ice cores drilled from a glacier in a cave in Transylvania offer new evidence of how Europe's winter weather and climate patterns fluctuated during...

Retreating Yukon glacier caused a river to disappear

The massive Kaskawulsh Glacier in northern Canada has retreated about a mile up its valley over the past century. Last spring, its retreat triggered a...

Hidden lakes drain below West Antarctica’s Thwaites Glacier

Thwaites Glacier on the edge of West Antarctica is one of the planet's fastest-moving glaciers. Research shows that it is sliding unstoppably into the...

Study shows planet’s atmospheric oxygen rose through glaciers

A University of Wyoming researcher contributed to a paper that determined a "Snowball Earth" event actually took place 100 million years earlier than previously...

Researchers find seafloor valleys below West Antarctic glaciers

Glaciologists have uncovered large valleys in the ocean floor beneath some of the massive glaciers flowing into the Amundsen Sea in West Antarctica. Carved...

Mountain glaciers are showing some of the strongest responses to climate...

Mountain glaciers have long been a favorite poster child of climate change. The near-global retreat of glaciers of the last century provides some of...

During last period of global warming, Antarctica warmed 2 to 3...

Following Earth's last ice age, which peaked 20,000 years ago, the Antarctic warmed between two and three times the average temperature increase worldwide, according...

West Antarctic ice shelf breaking up from the inside out

A key glacier in Antarctica is breaking apart from the inside out, suggesting that the ocean is weakening ice on the edges of the...

New study shows when Pine Island Glacier retreat began

Reporting this week (Wednesday Nov. 23) in the journal Nature an international team led by British Antarctic Survey (BAS) explains that present-day thinning and...

Nepal drains risky glacial lake near Everest

Nepal has successfully drained part of a giant glacial lake near Mount Everest, averting risk of a disastrous flood that could have threatened thousands...

UCI and NASA document accelerated glacier melting in West Antarctica

Two new studies by researchers at the University of California, Irvine and NASA have found the fastest ongoing rates of glacier retreat ever observed...

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...
