Unraveling a paradox of Himalayan glacier melt
One in five glaciers on Earth are covered with a layer of rocky debris. The presence of debris influences how glaciers melt. In the Himalaya, debris covers most large glaciers, and it is so thick that it should insulate the ice, slowing the rates of.....»»
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-.....»»
Desert dust collected from glacier ice helps document climate change
Researchers from The Ohio State University are using dust trapped in glacier ice in Tibet to document past changes in Earth's intricate climate system—and maybe one day help predict future changes......»»
Drastic retreat of Norway"s largest glacier highlights scale of climate change
A geography expert from The University of Manchester has demonstrated the speed and scale of climate change in a new book, by outlining the immense changes to Norway's largest glacier he has observed during his career......»»
Volcanic activity and low ocean oxygen events linked to climate warming and rapid ice melt during last ice age
A chemical analysis of sediment cores from the North Pacific Ocean show a consistent pairing of volcanic ash and hypoxia, a low ocean oxygen condition spanning thousands of years, during times of rapid climate warming at the end of the last ice age,.....»»
Plant hormones to help prevent Striga invasion
As part of a multipronged approach to prevent infestations by the parasitic plant Striga hermonthica, researchers are unraveling the role of plant hormones, known as strigolactones (SLs). Their latest research is published in Science Advances......»»
Cheap printer alert: get this HP Inkjet with 6 months of ink for $59
The HP Deskjet 2742e is looking cute in Himalayan Pink. A perfect pickup for a crafty student at just $59......»»
Vegetation regulates energy exchange in the Arctic
Global warming is changing the Arctic by causing permafrost thaw, glacier melt, droughts, fires and changes in vegetation. These developments are strongly linked to the energy exchange between land and the atmosphere. Researchers at the University of.....»»
Goats and Sheep Are Brawling in the Rockies. Blame Glacial Melt
The climate crisis may explain fights as disappearing ice fuels interspecies competition—with goats nearly always winning......»»
Fact check: Human-driven global warming increased Larsen ice shelf melt
The claim: Study shows that 'CO2 emissions play no role' in Antarctic Larsen ice shelf melt.....»»
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.....»»
A Reboot of the Maxwell’s Demon Thought Experiment—in Real Life
Physicists just reconstructed a 19th-century paradox that seems to violate the second law of thermodynamics (but really doesn’t)......»»
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.....»»
Black holes can’t trash info about what they swallow—and that’s a problem
Solving the information paradox could unlock quantum gravity and unification of forces. Enlarge (credit: Aaron Horowitz/Getty Images) Three numbers. Just three numbers—that’s all it takes to completely, unequivocally, 100.....»»
Marine ice sheets were decisive in acceleration of global warming during the last deglaciation
The intensity and rate of melt during the penultimate ice melting was much higher than previously thought, according to a study published in the journal Nature Communications. According to conclusions of the study, in this climate change scenario, th.....»»
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.....»»
Researchers detect the first definitive proof of elusive sea level fingerprints
When ice sheets melt, something strange and highly counterintuitive happens to sea levels......»»
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.....»»
