The main issue is that sea ice is fresher than sea water (has less salt), and since salty water is more dense (1028 kg / m3) than fresher water (1004 kg / m3 for 5 psu), the volume of sea water displaced by the ice is slightly less than the volume of the ice if it melted.

However, because they are partly submerged, their direct contribution to sea level rise is much smaller than the contribution made by the melting of an equivalent volume of (land - based) ice sheets.

The divergence in timing of sea ice loss between models and data — decades as represented by ice volume in Figure 3 — is physically irreconcilable.

Already 80 per cent by volume of summer sea - ice has been lost, and regional warming of up to 5 ˚C may have already pushed the Greenland ice - sheet past its tipping point.

Dr. Curry implies (as far as I understood it) The «stadium wave» hypothesis is based by interplay between North Atlantic Ocean temperatures oscillation (AMO) and the changes in the sea ice volumes in the Siberian Arctic Ocean region.

The fact that a great deal of the melt in Arctic sea ice is affected by the accumulating heat in the oceans and the fact that energy is advected to the Arctic via the oceans in much larger amounts than via the atmosphere and the extreme loss we've seen in Arctic sea ice volume as a result means nothing to the «skeptics».

It sounds like you have no clue about the details of sea ice loss over the past few decades, nor the most critical of all the metrics — see ice volume, which is directly impacted by the warmth of both the ocean water as well as the atmosphere.

Carr, J. (2014) Recent retreat of major outlet glaciers on Novaya Zemlya, Russian Arctic, influenced by fjord geometry and sea - ice conditions Journal of Glaciology, Volume 60, pp. 155 - 170 (16)

You wrote - «The fact that a great deal of the melt in Arctic sea ice is affected by the accumulating heat in the oceans and the fact that energy is advected to the Arctic via the oceans in much larger amounts than via the atmosphere and the extreme loss we've seen in Arctic sea ice volume as a result means nothing to the «skeptics».»

In the decade from the 80's to the 90's, the sea - ice volume minimum dropped by 2000 km3.

This huge volume of ice lowered global sea level by around 120 meters as compared to today.

Another month has passed and so here is the updated Arctic sea ice volume graph as calculated by the Pan-Arctic Ice Ocean Modeling and Assimilation System (PIOMAS) at the Polar Science Centice volume graph as calculated by the Pan-Arctic Ice Ocean Modeling and Assimilation System (PIOMAS) at the Polar Science CentIce Ocean Modeling and Assimilation System (PIOMAS) at the Polar Science Center:

Even with the unimaginably extensive sea surface chemical ice nucleation onslaught by the geoengineers, the Arctic sea ice volumes have continued to plummet as shown in the graph above.

Poitou & Bréon do not explain why the ice pack volume would be relevant for the albedo; according to Haas (2005)[47] the changes of the thickness of the sea ice are small since they are correctly measured by an airborne radio apparatus, only over the Arctic.

Similarly, ice above sea level will produce 6 % less water by volume.

Reynolds (Public), 4.06 (3.49 - 4.63), Statistical / Heuristic Because the decline in extent is due to increasing ease with which open water can be revealed by declining volume, a simple method is used to predict September sea ice extent based on May sea ice volume for the Arctic Ocean from the PIOMAS model.

Since 1979, the volume of Summer Arctic sea ice has declined by more than 80 % and accelerating faster than scientists believed it would, or even could melt.

The ice sheets regulate sea levels, store volumes of ice whose melting would raise sea level by up to 61 metres.

There is, however, a subtle but important qualification: if Artic ice should melt, the sea level will not change because the volume of water created by melting ice is equal to the volume of water that ice displaces when floating.

By volume, 75 % of the Arctic sea ice is already gone.

They determined, however, that this volume had now increased by a further 3 cubic miles each year, prompted by an acceleration in the rate at which the ice caps and glaciers are melting.Unlike what many other scientists have said — including, most prominently, NASA's James Hansen (who believes that a rise in 17 inches by 2100 will be mainly precipitated by the melting of ice sheets)-- the authors of this study believe that the loss of ice from glaciers and ice caps will account for the majority of the expected rise in sea levels.
