Global warming has made iconic Andean peak unrecognizable 2019-09-11T04:00:00Z This great melting will affect ecosystems and the creatures within them, like the salmon that spawn in meltwater streams. ‘When the Glaciers Disappear, Those Species Will Go Extinct’ 2019-04-17T04:00:00Z The extra meltwater trickles down into the porous snow on top of the ice sheet and refreezes there once temperatures go back down, the researchers note. "Hair Dryer" Winds Could Strain Vulnerable Antarctic Ice Shelf 2019-04-12T04:00:00Z Part of the meltwater runs off, but the rest that does not run off stays in place and refreezes. Rain is melting Greenland ice sheet even in winter, alarming study says 2019-03-07T05:00:00Z He had time to look around, to be astonished, before getting caught in the torrent of meltwater and giving the agreed signal to "get me... out of here". Glimpsing a world beyond human extinction 2019-04-29T04:00:00Z Meanwhile, Antarctic meltwater will trap warm water under the surface, accelerating the break-up of the West Antarctic ice shelf and contributing to a rise in ocean levels that could hit 20 inches by 2100. What does it take to destroy a world order? 2019-03-03T05:00:00Z Reducing or eventually eliminating the contribution of this meltwater will raise stream temperatures. ‘When the Glaciers Disappear, Those Species Will Go Extinct’ 2019-04-17T04:00:00Z In 2002, the nearby Larsen B ice shelf abruptly collapsed, likely weakened by a series of unusually warm summers that caused large amounts of meltwater to accumulate on its surface. "Hair Dryer" Winds Could Strain Vulnerable Antarctic Ice Shelf 2019-04-12T04:00:00Z But glacial retreat will also have an impact on hydropower, as glaciers shrink to the point where meltwater flows start to decline. Where Glaciers Melt Away, Switzerland Sees Opportunity 2019-02-14T05:00:00Z "It was beautiful," he says, "except when I was getting absolutely hammered by the meltwater stream, penduluming me out and smashing me back in." Glimpsing a world beyond human extinction 2019-04-29T04:00:00Z They have filled up at least a quarter of the meltwater lake at the foot of the glacier in the Aoraki/Mount Cook National Park, reports say. Huge ice chunks break off Tasman Glacier 2019-02-08T05:00:00Z Water temperatures must be just right for salmon to develop, so, as glacial meltwater declines and stream temperatures rise, populations may be affected. ‘When the Glaciers Disappear, Those Species Will Go Extinct’ 2019-04-17T04:00:00Z During the warm summer months, meltwater from glaciers tends to run downstream and help fuel nearby streams and rivers. World's "Third Pole" Is Melting Away 2019-02-04T05:00:00Z Reduced glacial meltwater will also affect the timing of peak flows to many hydroelectric plants, forcing power companies to adjust output seasonally. Where Glaciers Melt Away, Switzerland Sees Opportunity 2019-02-14T05:00:00Z But as the earth warms, the paper concludes, the vast plains of southwestern ice will increasingly melt, with the meltwater flowing to the ocean. Greenland’s Melting Ice Nears a ‘Tipping Point,’ Scientists Say 2019-01-21T05:00:00Z Lamarche-Gagnon et al. hypothesize that this winter storage allows meltwater to become enriched with methane through interaction with sediments in an oxygen-free environment. Methane beneath Greenland’s ice sheet is being released 2019-01-01T05:00:00Z One recent study found that Antarctic meltwater flowing into the ocean creates a layer of cold, fresh water that pushes warmer, saltier water up under the continent’s ice shelves, accelerating ice loss2. Massive ocean carbon sink spotted burping CO2 on the sly 2018-12-13T05:00:00Z That’s because its river basins are fed by both glacial meltwater and rainfall from monsoons, and in some places the monsoons are the more important source. World's "Third Pole" Is Melting Away 2019-02-04T05:00:00Z One of those plants is fed by meltwater from the Aletsch Glacier, the longest in the Alps. Where Glaciers Melt Away, Switzerland Sees Opportunity 2019-02-14T05:00:00Z The meltwater that flows from the 90,000 glaciers in High Mountain Asia is critical to the lives and livelihoods of the people downstream. Asia's glaciers put the brakes on 2018-12-10T05:00:00Z Using computer simulations, the team identified a few possible sources of the excess CO2, including locations on the western flank of the volcano where meltwater full of dissolved gases emerges from beneath the peak-covering glacier. This ice-covered Icelandic volcano may emit more carbon dioxide than all of the country’s other volcanoes combined 2018-09-21T04:00:00Z The later meltwater is necessary to sustain the streams and rivers on which plants, animals, farms and cities all depend. Climate change could render many of Earth’s ecosystems unrecognizable 2018-08-30T04:00:00Z Shrestha added that communities at high elevations, located very close to mountain glaciers, may depend more heavily on glacier meltwater. World's "Third Pole" Is Melting Away 2019-02-04T05:00:00Z But the Swiss are also counting on hydropower companies to expand production, even though glacial meltwater will eventually decline. Where Glaciers Melt Away, Switzerland Sees Opportunity 2019-02-14T05:00:00Z But repeated glaciations gradually scoured this grit away, and meltwater swept it into the ocean. Seafloor cores suggest sticky, thick glaciers caused mysterious shift in ice age rhythms 2018-08-22T04:00:00Z The authors interpreted these intrusions as evidence of meltwater originating from the Cordilleran Ice Sheet. A fresh take on ancient climate change in the North Pacific 2018-07-10T04:00:00Z Today the lake is even more potentially dangerous, swollen with glacial meltwater like an almost-overflowing bathtub.

But now it accelerates every year, exceeding all predictions. It will likely cause a pulse of meltwater into the oceans.” Rising seas: 'Florida is about to be wiped off the map' 2018-06-26T04:00:00Z That will collect meltwater from what remains of the Oberaletsch, as well as runoff from rain and melting snow. Where Glaciers Melt Away, Switzerland Sees Opportunity 2019-02-14T05:00:00Z In some cases, the meltwater is originating almost 200 miles from the hard-hit downstream areas in Washington. Okanogan River Basin braces for more flooding 2018-05-17T04:00:00Z “This paper kind of says meltwater is winning,” said Anders Levermann, a climate scientist at the Potsdam Institute for Climate Impact Research. Antarctic Glaciers Are Helping Drive Their Own Melt 2018-04-20T04:00:00Z If life did arise on Mars, then it may still be clinging on, lying dormant in the regolith and waiting for the next brief pulse of meltwater. Life clings on in the driest corners of the Earth 2018-03-01T05:00:00Z “This is why I believe we are witnessing the beginning of the largest meltwater pulse in modern human history,” Hal says. Rising seas: 'Florida is about to be wiped off the map' 2018-06-26T04:00:00Z Now, he said, companies like his must plan for a future of little or no glacial meltwater. Where Glaciers Melt Away, Switzerland Sees Opportunity 2019-02-14T05:00:00Z In the Columbia Basin, the high water already has also impacted the Tri-Cities area, driven there largely by releases from Grand Coulee Dam to make room for meltwater from Canada. Okanogan River Basin braces for more flooding 2018-05-17T04:00:00Z But the new research demonstrates that in some areas, where glaciers are producing unusually large quantities of meltwater, this mixing process isn’t happening. Antarctic Glaciers Are Helping Drive Their Own Melt 2018-04-20T04:00:00Z I then accounted for meltwater losses through evaporation, and compared this to net precipitation, distributed across river basins and across the catchments of a large number of dams.

How Greenland would look without its ice 2017-12-13T05:00:00Z In East Antarctica, observational data taken directly from the ocean suggested that glacial meltwater from the Moscow University Ice Shelf was freshening the nearby waters. Antarctic Glaciers Are Helping Drive Their Own Melt 2018-04-20T04:00:00Z Hence, the loss components of total meltwater that I used in my calculations are too small and the summed meltwater volumes reported here should be larger. Retraction: Asia’s glaciers are a regionally important buffer against drought 2018-02-13T05:00:00Z Based on the correlation between warming and speedup, Schuler and his colleagues suspect that the trigger for the surge was meltwater that trickled down through crevasses and accumulated at the glacier's base, summer after summer. Why slow glaciers can sometimes surge as fast as a speeding train—wiping out people in their path 2017-11-30T05:00:00Z The toe of the ice that was sending meltwater down one river north to the Bering Sea retreated so far that the water changed course and now flows south to the Gulf of Alaska. Bigger, Faster Avalanches, Triggered by Climate Change 2018-01-23T05:00:00Z An improved analysis of modelled and observed meltwater volumes would constrain lake depths using multi-spectral remote sensing2 and would integrate modelled melt rates over individual catchments, rather than the whole region. Corrigendum: Widespread movement of meltwater onto and across Antarctic ice shelves 2017-11-07T05:00:00Z Cranberries have grown wild in North America for thousands of years, since receding glaciers left cranberry-friendly organic deposits in meltwater ponds and wetlands.

An Iraq veteran finds healing as he hikes from Mexico to Canada 2017-10-27T04:00:00Z But a major role for meltwater suggests that "we are likely to see more glacier surges in a warming world," Yao says. Why slow glaciers can sometimes surge as fast as a speeding train—wiping out people in their path 2017-11-30T05:00:00Z The researchers suspected these spurts of sea-level rise were driven by pulses of meltwater from destabilizing glaciers. Oceans Can Rise in Sudden Bursts 2017-10-20T04:00:00Z The research also suggests that areas with more intense meltwater runoff are seeing the most expansion along the coastline. Greenland's Coasts Are Growing as Seas Rise 2017-10-05T04:00:00Z That is a loss not just for science but for people in other Andean countries who rely on meltwater from tropical glaciers.

Scientist at Work Blog: Ecological Connectivity as Climate Warms 2012-01-20T16:58:32Z Will the world’s shrinking glaciers produce more or less icebergs, meltwater, and windblown dust and will this help or hinder photosynthesis in the ocean? Following the Ice: Is this Global Warming? 2012-07-12T19:45:02.967Z When glaciers first begin to recede, the rivers downstream initially swell with the added meltwater until the glacial supply starts to ebb. Melting in the Andes: Goodbye glaciers 2012-11-07T18:20:47.557Z Mr. Shaw said that as meltwater runs to the foot of a shrinking glacier, it “can make fissures and crevices more common” — and indeed some climbers have noticed more dangerous crevasses. Green Column: Retreat of Glaciers Makes Some Climbs Tougher 2011-12-26T04:35:07Z Early studies pegged the amount of meltwater in these river basins as high as 60 or 70 percent. New Research Casts Doubt on Doomsday Water Shortage Predictions 2011-10-24T18:45:00.283Z Furthermore, increased meltwater could also affect biodiversity and productivity in cryoconite holes, holes on the surface of glaciers that are filled with meltwater. Scientist at Work Blog: Ecological Connectivity as Climate Warms 2012-01-20T16:58:32Z But how much meltwater is leaving and reaching the ocean? When Greenland's Ice Melts, Where Does the Water Go? 2011-08-05T18:15:02.860Z The crew, which pulls together hydrologists, geochemists, geographers and historians, mainly from the United States and Canada, is tracking the fate of glacial meltwater as it runs from the mountains down to the ocean. Melting in the Andes: Goodbye glaciers 2012-11-07T18:20:47.557Z Efforts to remove climate-warming carbon dioxide from Earth’s atmosphere appear to be getting a helping hand from a surprising source: the iron in meltwater from Antarctic icebergs. Melting Icebergs Fertilize Ocean 2011-05-16T19:03:00Z In the Indus, they found, the meltwater contribution is 151 percent compared to the total runoff generated at low elevations. New Research Casts Doubt on Doomsday Water Shortage Predictions 2011-10-24T18:45:00.283Z Lake levels and ice thickness in the Dry Valleys are directly affected by glacier meltwater because the lakes do not have any outflow and the surfaces are perennially frozen. Scientist at Work Blog: Ecological Connectivity as Climate Warms 2012-01-20T16:58:32Z A piece of a global puzzle "We want to understand what happens to meltwater," Rennermalm says, showing visitors around her team's camp on a sunny July day. When Greenland's Ice Melts, Where Does the Water Go? 2011-08-05T18:15:02.860Z The meltwater from the glacier on top of the volcano ran down into the crater, chilling the magma and then the pressure from underneath caused an explosion.

Climate change is ridding the world's tropical mountain ranges of ice 2011-01-05T22:15:59.373Z These large amounts of sediments decrease surface albedo of the ice, leading to further meltwater generation. Scientist at Work Blog: Ecological Connectivity as Climate Warms 2012-01-20T16:58:32Z Warmer temperatures mean more ponds of meltwater on the ice’s surface. Green.view: Thinning on top 2010-06-15T11:54:00Z What precisely happened is still being researched, but it appears that meltwater and magma produced steam quite suddenly and the volcano popped its top like a shaken soda bottle. Scientists find it difficult to predict volcano behavior 2010-04-21T04:00:00Z He said that this was probably because meltwater from the ice-cap was no longer able to leak into the volcano. 'No tolerance' 2010-04-19T11:15:00Z And, ultimately, that means bad news for the several billion people who rely on meltwater from these glaciers via the major rivers of Asia, from the Indus to the Yangtze. Climate change is ridding the world's tropical mountain ranges of ice 2011-01-05T22:15:59.373Z Long-term records of the glacier mass balances in the Dry Valleys show they are in equilibrium; however, small changes in energy balance on the surfaces can result in large changes in the production of meltwater. Scientist at Work Blog: Ecological Connectivity as Climate Warms 2012-01-20T16:58:32Z "However, re-saturation of the drained soils with meltwater from the frozen soils -- as would happen following thawing -- increased nitrous oxide production by over 20 times," it said. Arctic thaw frees overlooked greenhouse gas: study 2010-04-04T18:26:00Z Satellite observations and computer models by scientists have shown that the Greenland ice sheet is melting at an accelerating rate, dumping large amounts of ice and meltwater into the North Atlantic. Mega-flood triggered cooling 13,000 years ago: scientists 2010-03-31T17:04:00Z The rooftop was littered with broken glass and scummy puddles of meltwater and little pebbles and a slurry of decomposing leaves, and there, yes, there were the footprints, just as advertised. Someone Comes to Town, Someone Leaves Town Although water flows in these rivers is actually increasing right now thanks to increased meltwater, Eriksson notes, "eventually this will turn into a decline." Climate change is ridding the world's tropical mountain ranges of ice 2011-01-05T22:15:59.373Z Climate scientists fear rapid global warming could trigger a sharp increase in the amount of meltwater from Greenland.
