But also keep in mind that Lambeck et al (2002) have suggested that loss of permanent ice over the Arctic Sea at the end of the last interglacial allowed for increased accumulation of snow and ice at high latitudes because of the increased amount of moisture available.

Would this accumulation result in ice / water - free tropical deserts (they do mention deserts but not in this context), deserts that would put an end to any serious atmospheric H2O warming resulting from the hot noon - day tropical temperatures?

To give another, more specific example, at a typical glacier on Mt. Baker, in Washington State, a summer temperature increase of 1 °C translates to a ~ 150 m increase in the altitude of the equilibrium line (the point where annual ice accumulation = annual loss), and a resulting ~ 2 km retreat of the glacier terminus.

Because the drains out of the various bathtubs involved in the climate — atmospheric concentrations, the heat balance of the surface and oceans, ice sheet accumulations, and thermal expansion of the oceans — are small and slow, the emissions we generate in the next few decades will lead to changes that, on any time scale we can contemplate, are irreversible.

The paper, combining evidence of driftwood accumulation and beach formation in northern Greenland with evidence of past sea - ice extent in parts of Canada, concludes that Arctic sea ice appears to have retreated far more in some spans since the end of the last ice age than it has in recent years.

Back - of - the - envelope calculations show that the latent heat absorbed by melting of ice after surges (e.g., the melting of > 1500 years of ice accumulation during Dansgaard - Oeschger events — which seem to have happened in unison across the northern hemisphere, or the longer > 5ky Bond cycles) can significantly contribute to the global energy balance.

Land - based ice in glaciers and ice - sheets will keep contributing to sea level rise as long as melting exceeds snowfall accumulation; stopping the growth of temperature would not stop the net melting.

The margins of all ice sheets (including Greenland) are in retreat, and accumulation is negative over almost the whole of the West Antarctic sheet.

Of course also in ice cores you might then have special problems for the respective years such as particular accumulation or very specific circulation patterns that somehow compensate for the general cooling.

I believe that what the phrase is trying to get at is either the acceleration relative to the pause in the 1950 - 1970 period, or the acceleration in accumulation of noticeable consequences — worldwide glacier melt, sea ice retreat, earlier onset of springtime, (possibly) increasingly intense hurricanes, Larsen - B breakup, melting of Greenland along the margins, etc..

And it means more time must be spent on those ice sheets, both in the melt zones and the places where accumulation of snow still dominates — including Swiss Camp, which I visited on the flanks of the ice sheet in 2004:

Some places in the source are great: the reference to IPCC2, for example, for ice accumulation.

[Response: Ice sheets are in equilibrium in a stable climate exactly because ablation (melt, in simple terms) balances accumulation (i.e. snowfall).

The acceleration increased the mass loss from 5 km3 ice / year in 1996 (12) to 36 km ice / year in 2005 (Table 1), which is 6 % of Greenland's total accumulation.

I am thinking the accumulation and loss of ice in antarctic should go in about 23 year cycles.

It follows that accumulation of ice must result in a fall in sea level, and vice versa.

In outline, the model supposes that the rate of change of ice extent has two terms - accumulation proportional to its length, and loss at the grounding line which is proportional to the cross-section area there, which because a constant width is assumed is proportional to the depth of the ice.

On the other hand, the correlation between accumulated emissions and accumulation of CO2 in the atmosphere is much better: it is a near fit over the last 100 + years (60 years of ice core data, near 50 years of MLO data).

Three ice cores with very high accumulation rates (1.5 m ice equivalent / year) for two of them, drilled with three different techniques (wet and dry), without clathrates or cracks in the ice, were compared.

Because of the high accumulation rate (1.2 m ice equivalent per year), they could make a detailed history of gas behaviour in firn and ice.

The net change in ice mass is the difference between this accumulation and peripheral loss.

«If the area of the Greenland Ice Sheet experiencing net melt expands to eclipse the accumulation zone of the ice sheet, the ice sheet will, by definition, be tipped into a state of inevitable decline,» said William Colgan, a research associate at the Cooperative Institute for Research in Environmental Sciences (CIRES) who did not participate in the new researIce Sheet experiencing net melt expands to eclipse the accumulation zone of the ice sheet, the ice sheet will, by definition, be tipped into a state of inevitable decline,» said William Colgan, a research associate at the Cooperative Institute for Research in Environmental Sciences (CIRES) who did not participate in the new researice sheet, the ice sheet will, by definition, be tipped into a state of inevitable decline,» said William Colgan, a research associate at the Cooperative Institute for Research in Environmental Sciences (CIRES) who did not participate in the new researice sheet will, by definition, be tipped into a state of inevitable decline,» said William Colgan, a research associate at the Cooperative Institute for Research in Environmental Sciences (CIRES) who did not participate in the new research.

This 20 - year variability is, however, significantly reduced in the northern (Camp Century and Agassiz Ice Cap) region, likely due to a larger distance from the Atlantic Ocean, and a much lower snow accumulation.

This snowpack accumulation near the poles, which gets its water via the Arctic and Antarctic oceans, that in turn rob it from equatorial latitudes of our oceans, also results in a reduction in the earth's spin axis moment of inertia and causes the spin rate to increase as evidenced in the recent history of the rate at which Leap Seconds are added to our calendar (see Wysmuller's Toucan Equation for more on this evidence that during this warm time with much greater polar humidity, earlier seasonal, later seasonal and heavier snows are beginning to move water vapor from the oceans to the poles to re-build the polar ice caps and lead us into a global cooling, while man - made CO2 continues to increase http://www.colderside.com/faq.htm).
