On decadal and longer time scales, global mean sea level change results from two major processes, mostly related to recent climate change, that alter the volume of water in the global ocean: i) thermal expansion (Section 5.5.3), and ii) the exchange of water between oceans and other reservoirs (glaciers and ice caps, ice sheets, other land water reservoirs - including through anthropogenic change in land hydrology, and the atmosphere; Section 5.5.5).

Since «there's an over two orders of magnitude (~ 120) difference between the amount of energy needed to add a litre to the ocean from melting ice (~ 334KJ)[and] thermal expansion of sea water (~ 40,000 KJ)», this means that sea - level rise, often offered as a «proxy» for «global warming», is actually not important.

They are assuming that a 2C rise in global temperatures will occur, sometime between 2015 and 2052, and this will affect particularly the sea ice extent, winds and the amount of open water on which these colonies depend.

Over the past century, the Antarctic has gone from being a vast Terra Incognita to a continent - sized ticking time bomb: according to NASA, Antarctica has lost «approximately 125 gigatons of ice per year [between 2002 and 2016], causing global sea level to rise by 0.35 millimeters...

New evidence suggest that the longest interglacial (the time in between ice ages)-- a warming period, called Marine Isotope Stage 11, more than 400,000 years ago, created nearly complete deglaciation of southern Greenland, thus contributed 4 - 6 meters to global sea level rise at that period.

For the past six years since publication of the AR4, the UN global climate negotiations were conducted on the basis that even without serious mitigation policies global sea - level would rise only between 18 and 59 cm, with perhaps 10 or 20 cm more due to ice dynamics.

If the trend is removed then connection between global temperature and sea ice vanishes (more or less - IIRC) because interannual weather factors are the main driver of short term changes.

Although global ocean temperatures are rising, a layer of fresher water immediately below the sea ice is thought to act as a buffer between the ice and the warmer Atlantic waters flowing into the Arctic Ocean basin at a lower level.

The emerging science points to a complex interplay between manmade global warming, natural climate variability, and sea ice dynamics that scientists are only just beginning to truly understand.

Based on ice - sheet model simulations consistent with elevation changes derived from a new Greenland ice core, the Greenland ice sheet very likely contributed between 1.4 m and 4.3 m sea level equivalent, implying with medium confidence a contribution from the Antarctic ice sheet to the global mean sea level during the last interglacial period.

So it seems quite clear that there is a potential connection, in a statistical sense, between human - caused global warming, declining Arctic sea ice, and the anomalous blocking pattern this winter that has added to other factors we know are tied to human - caused climate change (warmer temperatures and increased soil evaporation, and decreased winter snowpack and freshwater runoff) to produce the unprecedented drought this year in California.

Forecasts of future ice sheet behavior appear even more uncertain: Under the same high — global warming scenario, eight ice sheet models predicted anywhere between 0 and 27 cm of sea level rise in 2100 from Greenland melt.
