Sentences with phrase «ice in a feedback loop»

As the ice is increasingly punctured by cryoconite, more and more heat is captured, melting increasing amounts of ice in a feedback loop that might spell the end of pack ice — one of our most important defenses to runaway climate change.

Not exact matches

Polyakov says a positive feedback loop is underway, in which less summer sea ice will lead to warmer winter waters and even less summer ice in subsequent years.

Sea ice reflects most of the sun's energy, he explained, whereas the open ocean absorbs more energy, and thus the disappearance of sea ice triggers even more warming, in a positive - feedback loop called albedo.

A new study says that climate - induced feedback loops could lead to a change in ocean stratification and the more rapid melting of ice sheets.

«Greenland's ice is getting darker, increasing risk of melting: Feedback loops from melting itself are driving changes in reflectivity.»

As the ice - breaking feedback loop accelerates in years to come, more and more towering waves are likely to batter the shrinking ice cap.

It's also likely, Russell and his colleagues say, that the drying in Indonesia created a feedback loop that amplified ice age cooling.

Sea ice melt impacts local and global temperatures in a feedback loop.

In this case, incursions of circumpolar deep water onto the continental shelf are melting the ice stream at its base and encouraging grounding line recession, which results in a positive feedback loop and further grounding line recessioIn this case, incursions of circumpolar deep water onto the continental shelf are melting the ice stream at its base and encouraging grounding line recession, which results in a positive feedback loop and further grounding line recessioin a positive feedback loop and further grounding line recession.

I'm not saying this is like arranging deck chairs on the Titanic as it either A) more quickly or B) more slowly heads toward the ice berg, but I think we (as people, if not as scientists) should now start being concerned about reaching milestones in the warming (whether we reach them faster or slower) at which positive feedback loops kick in — even if this is difficult scientifically to quantify or prove.

The study, which has not yet been peer reviewed, brings new importance to a feedback loop in the ocean near Antarctica that results in cooler freshwater from melting glaciers forcing warmer, saltier water underneath the ice sheets, speeding up the melting rate.

The retreat of glaciers and shrinking of the Greenland ice sheet in the Arctic, for example, is predicted to cause significant sea - level rise, changes in the salinity of our oceans, and altered feedback loops that will make the Arctic warm up even faster.

Gore introduces the concept of abledo and shows how feedback loops could lead to dramatic reductions in ice, especially in the Arctic, and he mentions glacial earthquakes in Greenland, but he doesn't put a timeline on the melting of the ice sheets.

«In this condition, the ice sheet will continue to absorb more solar energy in a self - reinforcing feedback loop that amplifies the effect of warming,» wrote Ohio State polar researcher Jason Box on the meltfactor.org bloIn this condition, the ice sheet will continue to absorb more solar energy in a self - reinforcing feedback loop that amplifies the effect of warming,» wrote Ohio State polar researcher Jason Box on the meltfactor.org bloin a self - reinforcing feedback loop that amplifies the effect of warming,» wrote Ohio State polar researcher Jason Box on the meltfactor.org blog.

«Because snow and ice reflect the Sun's heat, this melting causes more heat to be absorbed, which causes more melting, resulting in another feedback loop.»

In one of the troubling feedback loops of the changing climate, dark ice is partially caused by the warmer Arctic summers climate change has brought us: More warmth means less fresh snowfall to cover areas of accumulated sediment, changes to the shape and size of ice grains that make them less reflective, and more liquid near the surface.

The increasing loss of Arctic sea ice is threatening polar bears across their range; melting sea ice is affecting the Arctic climate in a feedback loop; and scientists expect melting permafrost will release more carbon dioxide and methane.

Early models showed that once ice reached tropical latitudes, a positive feedback loop would take hold, in which ice cover would lead to lower temperatures, which would add more ice cover, which would lower temperatures even more.

And once the ice is gone and other feedback loops kick in, all bets are off.

«The trend in sea ice decline, lack of winter recovery, early onset of spring melting, and warmer - than - average temperatures suggest a system that is trapped in a loop of positive feedbacks, in which responses to inputs into the system cause it to shift even further away from normal.

In climatology the term feedback is usually connected to the corresponding feedback loop, e.g ice - albedo feedback [13].
