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.....»»
Best of Last Week – Solving Hawking"s black hole paradox, a new form of ice, bad cholesterol may not be so bad
It was a good week for physics research as work by two teams of theorists working independently may have solved Stephen Hawking's black hole paradox. The first demonstrated that black holes are more complex than thought, while the second followed up.....»»
Unraveling tautomeric mixtures
A team at HZB has developed a method of experimentally unraveling tautomeric mixtures. Based on resonant inelastic X-ray scattering (RIXS) at BESSY II, not only proportions of the tautomers can be deduced, but the properties of each individual tautom.....»»
"Quantum Hair" Could Resolve Hawking"s Black Hole Paradox, Say Scientists
Stephen Hawking's black hole information paradox has bedevilled scientists for half a century and led some to question the fundamental laws of physics. Now scientists say they may have resolved the infamous problem by showing that black holes have a.....»»
Italy seeks to study, sample Europe"s southernmost glacier
Italian scientists are racing against time to study, scan and sample Europe's southernmost glacier before it melts and disappears as a result of rising global temperatures......»»
Hot springs reveal where continental plates collide beneath Tibet
In the classic example of mountain-building, the Indian and Asian continental plates crashed—and continue colliding today—to form the world's largest and highest geologic structures: the Himalayan Mountains and the Tibetan Plateau......»»
Controversial Impact Crater Under Greenland"s Ice is Surprisingly Ancient
An anonymous reader shares a report: In 2018, an international team of scientists announced a startling discovery: Buried beneath the thick ice of the Hiawatha Glacier in northwest Greenland is an impact crater 31 kilometers wide -- not as big as the.....»»
Wormholes help resolve black hole information paradox
A RIKEN physicist and two colleagues have found that a wormhole—a bridge connecting distant regions of the Universe—helps to shed light on the mystery of what happens to information about matter consumed by black holes......»»
Self-sustained diverter oscillation mechanism identified in fusion plasma experiment
To harness the forces that power the sun to produce substantial clean energy on Earth, researchers heat fuel to such a high temperature that atoms melt into electrons and nuclei to form a hot, gaseous soup called plasma. Roughly 20 times the temperat.....»»
Seismic study reveals key reason why Patagonia is rising as glaciers melt
The icefields that stretch for hundreds of miles atop the Andes mountain range in Chile and Argentina are melting at some of the fastest rates on the planet. The ground that was beneath this ice is also shifting and rising as these glaciers disappear.....»»
Melting glaciers, fast-disappering gauge of climate change
A crack widens in the San Rafael glacier in Chile's extreme south, and a ten-storey iceberg crashes into the lake by the same name—a dramatic reminder of the impacts of global warming......»»
Accelerating melt rate makes Greenland Ice Sheet world"s largest "dam"
Researchers have observed extremely high rates of melting at the bottom of the Greenland Ice Sheet, caused by huge quantities of meltwater falling from the surface to the base. As the meltwater falls, energy is converted into heat in a process like t.....»»
Onset of modern sea level rise began in 1863, study finds
An international team of scientists including Rutgers researchers has found that modern rates of sea level rise began emerging in 1863 as the Industrial Age intensified, coinciding with evidence for early ocean warming and glacier melt......»»
Study: Satellites may help predict ice avalanche threats
Satellite images could offer a new way to monitor for avalanche threats to remote mountain communities, according to Aberdeen scientists studying a deadly Himalayan avalanche......»»
How to design a sail that won"t tear or melt on an interstellar voyage
Astronomers have been waiting decades for the launch of the James Webb Space Telescope, which promises to peer farther into space than ever before. But if humans want to actually reach our nearest stellar neighbor, they will need to wait quite a bit.....»»
How climate change is destroying Arctic coasts
Global warming is causing permafrost in the Arctic to thaw and sea ice to melt. As a result, coasts are less protected and are being eroded, while carbon stored in the soil and carbon dioxide are being released into the ocean and atmosphere. In a fir.....»»
Seawater seep may be speeding glacier melt, sea level rise
The melting of ice sheets at the points where they float on and along the world's oceans is a major climate culprit when it comes to sea level rise. But less is understood about the extent of melting that is due to warm, salty seawater that seeps und.....»»
Western US "megafloods" during last ice age might not have been so mega
After the Last Glacial Maximum in North America, a kilometer-thick ice dam at the toe of a glacier failed, allowing the waters of massive Lake Missoula to rush out and inundate the landscape of what is now eastern Washington. The flooding carved out.....»»
Human-induced climate change impacts the highest reaches of the planet—Mount Everest
Melting and sublimation on Mount Everest's highest glacier due to human-induced climate change have reached the point that several decades of accumulation are being lost annually now that ice has been exposed, according to a University of Maine-led i.....»»
Giant iceberg blocks scientists" study of "Doomsday Glacier"
Antarctica's so-called Doomsday Glacier, nicknamed because it is huge and coming apart, is mostly thwarting an international effort to figure out how dangerously vulnerable it is......»»
Scientists uncover how the shape of melting ice depends on water temperature
A team of mathematicians and physicists has discovered how ice formations are shaped by external forces, such as water temperature. Its newly published research may offer another means for gauging factors that cause ice to melt......»»
