If they begin to melt, however — particularly as they're exposed to warmer ocean water — the shelves become thinner and the grounding line begins to retreat backward, causing the glacier to become less stable and making the ice shelf more likely to break.

Thus, Thompson's observation about the retreat of the Quelccaya ice cap would be interesting, but not that important, if it was the only data point we had.

The second error is obvious from the fact that the recent warming is seen in the oceans, the atmosphere, in Arctic sea ice retreat, in glacier recession, earlier springs, reduced snow cover etc., so even if all met stations were contaminated (which they aren't), global warming would still be «unequivocal».

Nintendo EAD, the game's closeted, Tokyo - based crack team of inventors may have retreated from the buckshot heavens once explored in the Wii's Super Mario Galaxy titles, settling once again on terra firma (even if, predictably enough, it's often covered in ice or lava)-- but what a world.

The second error is obvious from the fact that the recent warming is seen in the oceans, the atmosphere, in Arctic sea ice retreat, in glacier recession, earlier springs, reduced snow cover etc., so even if all met stations were contaminated (which they aren't), global warming would still be «unequivocal».

But as a starting point, I'll propose now — and I'll change this if they disagree — the names of some leading scientists in this field who would NOT say there is sufficient evidence to conclude that human - caused global warming IS the main cause of increasing summer retreats of sea ice (although they would say there is strong likelihood that it will eventually dominate):

Ms. Gormezano is not a fan of the forecasting methods used by Dr. Amstrup to conclude that a two - thirds reduction in polar bears is possible midcentury if summer sea ice continues retreating.

The mountains can only perform these two functions if the ice sheet does not retreat and no two gaps in the mountains link up.

Thus, Thompson's observation about the retreat of the Quelccaya ice cap would be interesting, but not that important, if it was the only data point we had.

If the July forcing was like that in June and August, which seems to enhance ice retreat in comparison with an average year, we would have had another record low.

So if you apply a negative sign to the figure at the bottom of / / seaice.apl.washington.edu/AO/, I would expect colder than normal spring especially in the Eurasian Arctic, less retreat of sea ice this summer, then colder than normal this fall in the Eurasian Arctic....

It'd be nice to think that the world's nations would move more assertively to cut dependence on fossil fuels in light of new research showing that the retreat of Arctic sea ice from warming will modulate if warming is slowed.

But the continued retreat of sea ice presents a potential problem, especially if scientists stick with the historic data gap from 87 degrees northward to the pole.

If you meant glaciers retreating, i.e losing ice mass, then glaciers react to climate changes with a lag of decades to millenia.

On the other hand, if retreating snow and sea ice cover was the major cause, maximum warming would be expected at the surface.

Coinciding with cycles of reduced sea ice, glaciers on the island Novaya Zemlya in the Barents Sea, also underwent their greatest retreat around 1920 to 1940.61 After several decades of stability, its tidewater glaciers began retreating again around the year 2000, but at a rate five times slower than the 1930s.47 The recent cycle of intruding warm Atlantic water45 is now waning and if solar flux remains low, we should expect Arctic sea ice in the Barents and Kara seas to begin a recovery and Arctic glaciers to stabilize within the next 15 years.

If the low SLP in the central Arctic persists, we can expect to see rapid retreat of ice in these regions as well as in the Canada Basin.

Also, from museum.state.il.us: --LSB-» If «ice age» is used to refer to long, generally cool, intervals during which glaciers advance and retreat, we are still in one today.

What is not raised is that ice is dynamic, it advances and retreats, while the Arctic is warming the Antarctic is cooling and vice versa and if ice did not retreat, then the planet would be covered in ice.

If one looks at the full glacial record, every retreat and collapse of ice sheets are preceded by ever increasing dust accumulations.

If so, that makes each site moss has been exposed by retreating ice into a «thermometer» that reports current temperature of recent decades on an unusual scale — years before present (ybp and further back means warmer).

It's a bit of a non-sequiter really, because had they been so, they would not be recognisable as Viking ruins when the ice retreated, and certainly not discoverable if they are under ice now.

If there's a cold batch of years during a mass melt of the Greenland ice cap, the same denialists who insisted that the Greenland ice cap would never retreat will be boasting that warmists got it wrong.

I spent about two hours searching for corroboration on this — feeling skeptical «because had they been so, they would not be recognisable as Viking ruins when the ice retreated, and certainly not discoverable if they are under ice now,» — as you said.

These cause interesting, potentially stabilizing, feedbacks in models: if an ice shelf thins or retreats as the ocean or atmosphere warms, tidal currents can weaken as water depth increases, leading to lower melt rates.

But if the grounding line retreats, sending inland ice further afloat, the shelf may begin a runaway collapse.

If the ice sheets retreat the weight of the ice will be lifted from the ocean floor, the gas hydrates will be destabilised and the methane will be released.

If warming is supposed to be «global,» shouldn't sea ice retreat at both ends of the world?»

«Looking ahead, it is still a matter of when, rather than if, the Arctic will become ice - free in summer, but we expect to see periods where the ice melts rapidly and other times where it retreats less fast,» says Ed Hawkins, a climatologist at the University of Reading in the UK, commenting on the study.

If more ice arrives than melts or falls off, the terminus advances; if less ice arrives, the terminus retreatIf more ice arrives than melts or falls off, the terminus advances; if less ice arrives, the terminus retreatif less ice arrives, the terminus retreats.

If the ice - sheet bed deepens toward the center of the ice sheet, an instability exists, such that in the absence of additional stabilizers, the grounding line will advance with ice - sheet growth, or retreat with ice - sheet shrinkage, to a position where the bed rises towards the ice - sheet center.

Most of the WAIS is grounded below sea level and has the potential to collapse if grounding - line retreat triggers a strong positive feedback whereby ocean water undercuts the ice sheet and triggers further separation from the bedrock (35 ⇓ — 37).

If the current jet stream disruption is, as many believe, a consequence of Arctic ice retreat, the failure to predict it is perhaps connected.

Ice sheets resting on retrograde beds are inherently unstable, because once the grounding lines reach the edge of the «bowl», they will eventually retreat all the way to the bottom of the «bowl» even if the ocean water intruding beneath the ice doesn't get any warmIce sheets resting on retrograde beds are inherently unstable, because once the grounding lines reach the edge of the «bowl», they will eventually retreat all the way to the bottom of the «bowl» even if the ocean water intruding beneath the ice doesn't get any warmice doesn't get any warmer.

These results suggest that the tropospheric oxidizing capacity could change dramatically over the Arctic if summer sea ice is to retreat in the future, something that could impact the removal of important gases (methane, carbon monoxide) in this region.
