Canadian scientists recently published research on Lake Hazen on Ellesmere Island. They found that even a one-degree temperature increase is melting permafrost, shrinking glaciers, increasing sediment and changing the types of plants and animals found in the lake. Lead researcher Igor Lehnherr says ...
The Pine Island Glacier was one of the quickest retreating glaciers on Antarctica, but now the below the surface melting has come to a halt. Now we know of a new factor that influences the melting of ice sheet and help us to understand it better. Journal reference: Konrad et al (2018) Net retreat of Antarctic ...

From the Himalayas to the Alps and the Andes, glacial retreat is uncovering the boots and bones of long-lost mountaineers. But such discoveries involve a haunting, double revelation: each reclaimed climber reminds us of the glacier's own vanishing. Siachen Glacier, where Indian and Pakistani troops have battled ...
The expansion and retreating of ice sheets has shaped our world over millions and millions of years. While most of us get that retreating glaciers scoured rocks, cut out valleys and dropped deposits down-ice in sometimes strange formations, the understanding — for me at least — tends to drop off there.
But glacial retreat is still an abstract idea for many people, which makes it easy to ignore. As environmental historian Mark Carey puts it, “Most people in the United States have never encountered a glacier; nor would they be able to identify one even from close proximity.” Yet due to global interconnection, ...
The repercussions of these changes are manifold and varied, from retreating glaciers to an increase in the frequency and intensity of snow avalanches. A team of researchers has employed dendrochronology -– the reconstruction of past disasters as recorded in growth series of trees -– to disentangle the ...

Ice loss in this area has been happening for decades, but two of the five ice fields observed in 1988 had disappeared by 2009, NASA showed in a separate post. Now, three of the five ...
The availability of water under ever-increasing climate stress has never been more important. Nowhere is this more apparent than in glacial mountain regions where runoff from glaciers provides water in times of drought or low river flows. As glaciers retreat due to climate change, the water supplied to these ...
The twin brothers first summited the Cascade peak at age 10 and have since committed much of their lives to exploring, documenting, and advocating for the mountain. From forest fires to shrinking glaciers, the brothers can rattle off the mountain's history the way you might reminisce about an old friend.
Our study highlights the "hot spots" where retreating glaciers will cause water shortages in future. Many problems could be solved by more efficient use and better distribution of water on the level of the affected communities. In developing countries, this requires significant investment and a transfer of ...
Mapping the global impact of shrinking glaciers on river invertebrates ... same way to decreasing glacier cover wherever in the world they are, say scientists who have evaluated more than one million of them in diverse regions with shrinking glaciers, to determine the impact of global environmental change.
*At the time of posting, wildfires were burning in Glacier National Park, near Lake McDonald Lodge and along the Going-to-the-Sun road. Our thoughts are with all those affected by fires across the West, and our deepest appreciation goes out to the first responders managing the fire. In 1850 there were an ...
The shrinking and eventual disappearance of the glaciers will have wide ranging consequences for Switzerland, since most hydroelectric dams in the Alps draw their water from glaciers. Glacial retreat and the related thawing of permafrost will cause slope instability leading to more land and rockslides.
Climate change is causing glaciers around the world to melt, raising the risk of flooding and other problems. But residents of a remote area of Pakistan face floods for the opposite reason – their glaciers are growing. Experts say that more than 120 glaciers in Pakistan's north are stable, or even growing ...

Cullen, now working in Chile, researches innovative ways to monitor glacial retreat and effective climate change adaptation strategies. Focusing on Mocho Glacier in the Chilean Lake District, Cullen partners with local experts in Santiago and Valdivia to evaluate local vulnerability and hazards from rapid ...
Herdsmen-farmers' crisis in Nigeria has left deep wounds in the heart of many. The thought of the hundreds of lives that have been wiped off the face of the earth or the several viable communities deserted in the middle-belt region of the country is black and unbearable. Furthermore, the crushing ...

Models calibrated with remotely sensed data will simulate historical water flows and project how those flows may change as a result of dam construction and shrinking glaciers in the Himalayan headwaters due to climate change. The second grant will apply a social science approach through interviewing ...
Plants died off, food sources would have been scarce, and the previously retreating glaciers began to advance again, say the researchers. Human culture would have had to adapt to the harsher conditions, with populations declining as a result. "Computations suggest that the impact would have depleted ...
They'll also talk about shifting weather patterns in Alaska, beaver colonization in the Arctic, and how shrinking glaciers are affecting Alaska's coastal ecosystems. Presentations are about 45 minutes long, plus 15 minutes for questions. The events will take place every Tuesday night at 7 pm for the next six ...
The first study, by Matthias Huss and Regine Hock, looks at the effect shrinking glaciers have on local water supplies. Glaciers help sustain rivers downslope through the drier months by providing a constant stream of meltwater, like a frozen water tower that collects in the winter and rations it out over the ...
The glacial retreat took more than 10,000 years, Carlson noted, but the "tipping point" that caused the reduction of the Atlantic current may have happened in a single summer. "As the ice sheet retreated, there were enormous freshwater lakes that drained down the Mississippi and into the Gulf of Mexico," ...
Moreover, modern dust transport at high latitudes provides a highly suitable analogue for reconstructing paleo-aeolian processes that operated during the Pleistocene, as well as for understanding and quantifying the dependency of present-day processes—particularly glacial retreat—on global warming.
New research suggests the dissipation of heat from Earth's interior is responsible for the acceleration of the seaward slide of Greenland's ice sheets. The descent of Greenland's shrinking glaciers is well documented, but the latest research -- published this week in the journal Scientific Reports -- is the first ...
The team then analyzed these high-activity periods in relation to times of glacial retreat. They found that the number of eruptions declined as the climate cooled and glacial cover increased. During that time, there was also a reduction in the volume of lava that came out of Icelandic volcanoes. The reverse ...
3. Pick landmarks wisely. Retreating glaciers and changing river courses make unreliable handrails. Instead, use unmovable objects like ridgelines. Getting cliffed out? Scan the horizon for a ramp you can reach by backtracking. Don't hesitate to turn around—it might be the only way. 4. Master the 'schwack.
This gigantic rock was deposited near Bentham by retreating glaciers at the end of the last Ice Age. The local legend goes that it and three other large rocks, which were thought to have been later cut into scythe sharpeners, were dropped by the devil while he was on his way to build Devil's Bridge over the ...
That could stall glacial retreat dramatically, and maybe even reverse it. In Wolovick's virtual experiments, even the least successful version of the sills slowed a glacier's collapse by 400 or 500 years. It's all still a huge if, Wolovick admits, that requires more research. But if it works, it could buy some crucial ...

Ever since I learned about this problem and discovered that global warming causes more rainfall, changing seasons, shrinking glaciers and rising sea levels, I wanted to know what we can do about it. Please join me to make small changes, such as walking instead of using a car, switching to energy-saving ...
We constantly see across all the media that "the science is in" regarding global warming. But contrary to this widespread belief, there are many notable scientists that disagree. Because of the rush to legitimize "Cap and Trade" by our various state and federal authorities, you rarely see any discourse ...
There was also a lag between retreating glaciers and increased volcanic activity, but it was shorter, the team found — although the study cautions there could be other climate-related factors that contributed to the compressed lag time. Copyright 2017 NPR. To see more, visit http://www.npr.org/.
For many people around the world, glacial retreat is an abstract concept—one that exists in photographs and in scientists' bleak forewarnings of the consequences of ice loss. But filmmakers Raphael Rogers and Paul Rennick got to see it all firsthand. Rogers and Rennick were driving through the back ...

When conditions changed again a thousand years later, this time to favour glacial retreat, volcanic activity picked up after a few hundred years. Based upon these findings, Dr Swindles argues that even minor increases and decreases in glacier cover probably do affect volcanic activity, albeit with a time lag ...
From The Guardian: “A German court has ruled that it will hear a Peruvian farmer's case against energy giant RWE over climate change damage in the Andes, a decision labeled by campaigners as a 'historic breakthrough.' Farmer Saul Luciano Lliuya's case against RWE was 'well-founded,' the court in the ...
The Northern Sea Route (NSR) is the Arctic national waterway of the Russian Federation, stretching some 3000 nautical miles and seven time zones across the top of Eurasia. As defined by Russian law, the NSR includes the normally ice-covered coastal waters and marine routes within the country's ...
AT THE end of the last ice age, around 11,700 years ago, Earth's climate began warming rapidly. As the planet heated up, its vast glaciers fell back. Almost immediately afterwards (in geological terms, at least) volcanic activity surged. That was nothing new. The geological record has plenty of evidence of ...

According to a recent Instagram from Superpark Dachstein in Austria, it looks like the summer snowboarding hot spot will no longer be opening its doors for riding during the warm months. Citing glacial impact, the resort that has seen the likes of Marko Grilc, Anna Gasser, Max Zebe and countless others is ...
Shrinking glaciers are leading to the birth of more Adelie penguins in the East Antarctica region, researchers report. The findings show that in the last 14,000 years, the population of Adelie penguins has seen a 135-fold increase as additional breeding sites become exposed by retreating glaciers.
