Getz glaciers on the run
Using a 25-year record of satellite observations over the Getz region in West Antarctica, scientists have discovered that the pace at which glaciers flow towards the ocean is accelerating. This new research, which includes data from the Copernicus Se.....»»
Glaciers have existed on Earth for at least 60 million years—far longer than previously thought
Glaciers have been present somewhere on Earth for at least 60 million years, a period stretching back almost to the time of the dinosaurs. That's the key finding of our new research, which pushes the date when the planet was last glacier-free back by.....»»
Greenland"s glaciers might be melting 100 times as fast as previously thought
A computer model has been created by researchers at the Oden Institute for Computational Engineering and Sciences at The University of Texas at Austin that determines the rate at which Greenland's glacier fronts are melting......»»
Florida mints radiated as peninsula sank and resurfaced during ice ages, finds study
During the ice ages of the Pleistocene, the Florida peninsula regularly grew to twice its current size as glaciers expanded near the planet's poles, only to be reduced to a series of islands as melting ice returned to the sea during warm periods. All.....»»
Studying the impacts of glacial flour on ecosystems
The meltwater from glaciers carries thousands of tiny rock fragments into the sea. Using a special camera, researchers at the University of Oldenburg can make these mineral particles visible in all their diversity—and investigate their impact on ec.....»»
From the air, scientists map "fast paths" for recharging California"s groundwater
Thousands of years ago during the last Ice Age, rivers flowed from giant glaciers in the Sierra Nevada down to the Central Valley, carving into rock and gouging channels at a time when the sea level was about 400 feet lower. When the glaciers retreat.....»»
Study shows hundreds of thousands of tons of bacteria are being released by melting glaciers
A team of researchers affiliated with multiple institutions across Europe, the U.K. and Canada has found that hundreds of thousands of tons of bacteria are currently being released annually into the environment by melting glaciers in the northern lat.....»»
Researchers develop a new method for analyzing rock glaciers
Standing on a rock glacier is what Tyler Meng imagines it would be like to stand on the surface of Mars. The glacier's barren and wrinkled landscape looks like Silly Putty that's drooped under gravity's pull, offering few clues that a frozen, debris-.....»»
Yellowstone, Kilimanjaro glaciers among those set to vanish by 2050: UNESCO
Glaciers at many UNESCO World Heritage sites including Yellowstone and Kilimanjaro National Park will likely vanish by 2050, the UN agency warned Thursday, urging leaders to act fast to save the rest......»»
How old is California"s Yosemite Valley?
First-time visitors to Yosemite Valley gape in awe at the sheer granite wall of El Capitan and the neatly sliced face of Half Dome, aware, perhaps vaguely, that rain and glaciers must have taken a long time to cut and sculpt that landscape. But how l.....»»
New tool helps researchers study remote glaciers
As warming atmospheric temperatures lead to glacier thinning and retreat around the world, understanding how glaciers are responding to climate change, algal growth, and impurities like dust and black carbon is vital. Understanding the response helps.....»»
Greenland Is Disappearing Quickly, and Scientists Have Found a New Reason Why
Meltwater from Greenland churns the ocean, speeding the loss of glaciers like stirring ice cubes in a glass of water.....»»
Net zero emissions: FUTEX outlines a sustainability vision
Environmental destruction and excessive use of fossil fuels have increased the average global temperature. The world is experiencing unusual but frequent El Nino and La Nina events, melting glaciers of the North and South poles. Even worse, droughts,.....»»
Unlocking the secrets of "glacier flour"
The meltwater from glaciers carries thousands of tiny rock fragments into the sea. Using a special camera, researchers at the University of Oldenburg can make these mineral particles visible in all their diversity—and investigate their impact on ec.....»»
Antarctic glaciers vulnerable to rising temperatures
On the East Antarctic Plateau there are huge glaciers under the sea. In order to improve future scenarios related to rising sea levels, scientists need to understand the ways in which these glaciers will respond to rising temperatures in the atmosphe.....»»
Observations confirm model predictions of sea-level change from Greenland melt
Rising sea levels from melting glaciers and ice sheets pose an increasing threat to coastal communities worldwide. A new analysis of high-resolution satellite observations takes a major step forward in assessing this risk by confirming theoretical pr.....»»
Listening to the song of melting glaciers
This is it, we have reached the bottom of the glacier. It is 327m under our feet. After drilling into the ice for six hours, our hot-water jet blasts into the sediment. The hose that connects it to the surface stops rolling and Thomas Schuler, the pr.....»»
Study: Heat wave led to unprecedented melt of Swiss glaciers
Switzerland's glaciers are melting like never before, an academic study released Wednesday found, with their ice volume declining by 6% this year amid rising concerns about global warming and a summer heat wave that swept across Europe......»»
As glaciers melt at an alarming pace, a geologist reflects on the legacy of ice ages and what the future may hold
With continued news of glaciers in Greenland, Antarctica, Alaska and the Alps, as well as other parts of the world, melting far faster than predicted, Tufts Now turned to an expert on ice sheets and the last ice age to better understand the big pictu.....»»
Study: Heatwave led to unprecedented melt of Swiss glaciers
Switzerland's glaciers are melting like never before, an academic study released Wednesday shows, with their ice volume declining by 6 percent in a "disastrous" 2022 amid rising concerns about global warming and a summer heat wave that swept across E.....»»
An integrated modeling framework to assess surface and ground water resources
Groundwater—the water contained in porous and fractured rocks underground—is the largest freshwater source on Earth apart from the ice caps and glaciers. It feeds into rivers, lakes, and other surface water bodies and is essential for ecosystems......»»
