I assume every glacier is different, so there's no single answer whether meltwater is successfully penetrating through cracks to the base and staying melted, and whether stresses in the ice are opening cracks further, and which glaciers have beds sloping downhill going inland

Other factors would include: — albedo shifts (both from ice > water, and from increased biological activity, and from edge melt revealing more land, and from more old dust coming to the surface...); — direct effect of CO2 on ice (the former weakens the latter); — increasing, and increasingly warm, rain fall on ice; — «stuck» weather systems bringing more and more warm tropical air ever further toward the poles; — melting of sea ice shelf increasing mobility of glaciers; — sea water getting under parts of the ice sheets where the base is below sea level; — melt water lubricating the ice sheet base; — changes in ocean currents -LRB-?)

And sea level rise will affect the glaciers that have grounding lines upstream and under the ice — the grounding line moves further upstream... would this touch some of the deeper lakes under the ice cap?

Since very little moisture evaporates from ice, the snowfalls become much lighter — and far to the south the glacier front comes to a stop.

In contrast, Flask and Leppard glaciers, further south, did not accelerate as they are still buttressed by an ice shelf.

Further south, glaciers drain larger reservoirs of ice, and the thinning of Larsen C [Shepherd et al., 2003] may trigger an even larger contribution to sea level.

The relatively warm water flowing through the glacier also carries surface heat deep inside the ice sheet far faster than it would otherwise penetrate by simple conduction.

The new report further states that greenhouse gas emissions at or above current rates would induce changes in the oceans, ice caps, glaciers, the biosphere, and other components of the climate system.

Given that calving Patagonia glaciers were far more sensitive to climate fluctuations than western Antarctica, and given the likelihood that paleo sea - ice extent around Antarctica deflected iceberg drift from present pathways, it would be helpful to know how they confirmed the respective continental sources of any dated sediments.

All ice types, including massive ice sheets, mountain glaciers and Arctic sea ice (frozen sea - surface), are for the most part melting far faster than predicted three years ago.

Further up - glacier, the ice at the grounding line is 600 - 700 m thick.

The impacts of ice shelf collapse and ensuing glacier acceleration are substantial, but in general, the effects of ocean melt are proving to be far more important in controlling ice sheet mass balance.
