My report identified that the IPCC report was greatly underestimating the rates of change of sea level rise, Greenland and Antarctic Ice melt rates, Arctic temperature amplification levels and completely ignored increased levels of Arctic methane emissions.

So it currently includes a [positive] contribution from the ice - albedo feedback, because our current climate possesses sea - ice that will be melted by a modest increase in temperatures.

Specifically, increasing the snow albedo delayed the melting of snow and sea ice in spring, which increased the albedo difference to the experiment in which snow grains were assumed spherical.

The underlying logic is sound: as sea ice melts, it exposes darker ocean water, which absorbs more of the sun's heat, causing the water temperatures to increase.

Other indicators such as ocean acidification, increasing deep ocean heat, melting ice and permafrost, shrinking snow pack, and sea level rise further make the case that the additional carbon dioxide is affecting the global climate system.

And this is just one element in the sea level rise — small ice caps are melting faster, thermal expansion will increase in line with ocean heat content changes and Antarctic ice sheets are also losing mass.

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-?)
