The MISI is based on a number of studies that indicated the theoretical existence of the instability...

It may not be a magical ice palace wedding, but a simple icebreaker could do the trick to get conversation flowing and start a romantic journey all your own.

The problem with the paleoclimate ice sheet models is that they do not generally contain the physics of ice streams, effects of surface melt descending through crevasses and lubricating basal flow, or realistic interactions with the ocean.

(By the way, the I.P.C.C. didn't exclude the ice - sheet dynamics but they did say that the models currently were not good enough to do anything but to linearly extrapolate, and therefore they simply assumed the flow from Greenland and Antarctica based on the period 1993 - 2003.)

Ice flow dynamics have to matter a lot, and the IPCC's 80 cm doesn't include them.

The denialist cut - paste attempts to — via logical fallacy, hand - waving and dissembling — make it appear that... that... well, who knows but it isn't germane nor does it refute eroding coastlines due to less ice, nor does the denialist cut - paste refute the facts of melting permafrost, CH4 release, warmer Arctic temps, birds moving north into the Arctic, increased freshwater flow into the northern seas, and numerous other indicators.

It's about increased flow of the ice into the ocean, and from * there * it melts (and of the icebergs raise sea level whether they melt or not).

This illustrates two things, that PIG flow regime has not changed much for quite awhile and two that all the action from topography and changing basal conditions is happening lower in the ice stream.

Terran: An examination of a map of glacier velocity for either the Pine Island presented in this post or of the ice streams feeding the Ross Ice Shelf indicate that most of the ice sheet region is not a fast flow regiice streams feeding the Ross Ice Shelf indicate that most of the ice sheet region is not a fast flow regiIce Shelf indicate that most of the ice sheet region is not a fast flow regiice sheet region is not a fast flow region.

As for Antarctica — there are many differences, not least the heat content of the Southern Oceans, the isolation of the continent, mostly divergent sea ice flow, etc..

The glaciological community has for decades harbored the widespread belief that the thermal evolution of the ice sheet, and the effect of this evolution on ice flow, are central in the ice - age cycling (not all communities agree, but there is plenty of literature on this from the land - ice crowd), so use of a temperature - independent rheology for the ice leaves out one favored explanation for termination of extensive glaciation.

Of course, most IPCC scientists don't believe that rapid dynamical changes in ice flow can happen!

After the journal Science published a paper earlier this month concluding that summertime gushers of meltwater percolating to the base of Greenland's ice sheet didn't appear to speed the seaward flow of ice, one result was a burst of excited comments from bloggers and others asserting that the impacts of global warming have been hyped.

The numbers would have become slightly lower, but this approach would not have mixed up very different levels of uncertainty, and it would have been clear what is included in the table and what is not (namely ice flow changes), rather than attempting to partially include ice flow changes.

Half of the ice flows in the Karakoram range of mountains are advancing and not retreating, researchers announced in the first major study since a 2007 United Nations report warned the glaciers would melt by 2035, according to the Daily Mail.

This flow of ice, fed by the continuous formation of new ice on land and culminating in the breakup of the shelves on the outer fringe and the calving of icebergs, is not new.

Ice melting in mountainous regions not only affects river flows, it also affects sea level rise.

However, I'd contend that the variance explained or variability of the mid-latitude flow attributed to the AO is not well understood to infer anything much about the derivative of such variability due to Arctic Sea Ice change.

In his Environmental Research Letters paper Hansen claims that the IPCC 2007 figures are low because the IPCC says it is unable to evaluate possible dynamical responses of the ice sheets and therefore its figures do not include any possible rapid dynamical changes in ice flow.

They do not include «rapid and dynamical changes in ice flow», because the IPCC was too uncertain about how likely or influential these changes might be.

Surface melt on an ice sheet not only directly reduces the ice sheet mass but also can accelerate ice flow and even leads to further melting.

Heat pumps don't work worth a crap for heating when the outside air temperature is much below 50F because the outside heat exchanger ices up which stops the fan driven air from flowing through it.

The vulnerability of the ice sheets to warming could be increased by dynamical processes related to ice flow (not included in current models but suggested by recent observations) thereby increasing future sea level rise.

For instance, projections of sea level rise do not take into account the fact that the flow of ice from the ice sheets in Greenland and Antarctica could be faster in the future than they were in recent years.

Ice does not conduct heat well, and a rise of a few degrees in the air would take thousands of years to affect a glacier base a mile away, where it could lubricate the flow.

News like the disintegration of an ice shelf the size of Rhode Island a month ago conjures a vision that a warming world will lead to doom by drowning — not from melting ice shelves, which like melting ice in a glass do not change water levels, but from melting ice sheets sending their fresh water flowing toward the sea.

The IPCC did not consider changes in ice flow in these projections due to a lack of scientific data.
