Does the pattern of change (warming raises the equilibrium temperature, cooling decreases it), indicate a negative feedback on sea level change (e.g. as land ice melts it requires a little warmer temperature to continue to melt further land ice... and vice versa??).

So the main issue for me is that all «serious» studies show only «statistical trends» having some effects on some measurable quantities, (slight increase of average temperature, slight increase of sea level, slight decrease of northern, but not southern, sea ice,..)

As the years pass, Antarctica's lowering of sea level (by accumulating water as snow and ice) will decrease until eventually (20 years Zwally estimated) Antarctica will start to contribute to sea level rise.

The primary danger from global warming was supposed to be the sea level rise from melting ice caps but this hasn't occurred either and satellite measurements show that the rate of sea level rise has in fact decreased in 2004 to 0.37 mm / year in the Atlantic and 0.15 mm / year in the Pacific.

The 2009 State of the Climate Report of the US National Oceanic and Atmospheric Administration (NOAA) tells us that climate change is real because of rising surface air temperatures since 1880 over land and the ocean, ocean acidification, sea level rise, glaciers melting, rising specific humidity, ocean heat content increasing, sea ice retreating, glaciers diminishing, Northern Hemisphere snow cover decreasing, and so many other lines of evidence.

The decrease in albedo that accompanies the loss of sea ice is the phenom that underlies «arctic amplification» (as you point out, it has nothing directly to do with sea level rise).

So melting of ice on land, or precipitation from the atmosphere can only decrease the moment of inertia, so the rotation speeds up as land ice melts, and runs down to sea level.

For if decreasing mass means sea levels are going up, the converse is also true, If the ice is accumulating, the sealevel should have gone down.

-- cooling — decreasing sea level — increasing global sea ice (coming soon)-- decreasing atmospheric CO2 (coming soon)

We are also told that there have been dramatic decreases in the Arctic sea ice, and that sea levels are rising.

If CO2 rises much faster in this century than the last, decreasing land ice can be expected to contribute more strongly to rising sea levels than to date.

New paper finds East Antarctic ice sheet will have negative contribution to sea levels over next 200 years — Published The Cryosphere — Paper «studies one of the largest ice shelves in East Antarctica and predicts increased accumulation of ice on the surface of the ice shelf will have a net contribution of decreasing sea levels over the 21st and 22nd centuries.

If you get some guages from Alaska they will actually show a long term decrease in sea level since there is strong isostatic lift (increase in land height) due to the melting of the glaciers from the ice age.

Trends in the satellite - derived Arctic sea ice concentrations (1978 - 2002) show pronounced decreases in the Barents / Kara Seas, between the Chukchi and Beaufort Seas, the central Sea of Okhotsk and a portion of the Hudson / Baffin Bay by ∼ 2 - 8 % per decade, exceeding the 95 % confidence levsea ice concentrations (1978 - 2002) show pronounced decreases in the Barents / Kara Seas, between the Chukchi and Beaufort Seas, the central Sea of Okhotsk and a portion of the Hudson / Baffin Bay by ∼ 2 - 8 % per decade, exceeding the 95 % confidence levSea of Okhotsk and a portion of the Hudson / Baffin Bay by ∼ 2 - 8 % per decade, exceeding the 95 % confidence level.

8 months of the year, the slowly decreasing Arctic sea ice actually allows more heat to be lost from the Arctic ocean that it gains from the very low sunlight levels that are present due to increased evaporation, convection, conduction and radiation losses.

The evidence for AGW covers a number of areas: increases in CO2 levels, overall warming, a rise in sea levels, falls in snow cover, receding glaciers, a decrease in Arctic ice, earlier springs, treelines moving towards the poles.

These trends in extreme weather events are accompanied by longer - term changes as well, including surface and ocean temperature increase over recent decades, snow and ice cover decrease and sea level rise.

The G refers to global, thus the MEAN global T must rise, the mean sea ice extent must decrease, global sea level trend must increase, global tornadoes must rise, global floods must increase, the rate of global sea riseust rise, and all the global change MUST be catastrophic, and clearly outside of recent past global flux.

The Arctic has a lot of floating sea ice, and it is in the news a lot because it is decreasing dramatically, but sea ice loss in the Arctic does not directly contribute to sea level rise.

For example, the lower atmosphere and the upper layers of the ocean have also warmed, snow and ice cover are decreasing in the Northern Hemisphere, the Greenland ice sheet is shrinking, and sea level is rising (see Figure 1b).

For example, additional evidence of a warming trend can be found in the dramatic decrease in the extent of Arctic sea ice at its summer minimum (which occurs in September), decrease in spring snow cover in the Northern Hemisphere, increases in the global average upper ocean (upper 700 m or 2300 feet) heat content (shown relative to the 1955 — 2006 average), and in sea - level rise.

Scientific confidence of the occurrence of climate change include, for example, that over at least the last 50 years there have been increases in the atmospheric concentration of CO2; increased nitrogen and soot (black carbon) deposition; changes in the surface heat and moisture fluxes over land; increases in lower tropospheric and upper ocean temperatures and ocean heat content; the elevation of sea level; and a large decrease in summer Arctic sea ice coverage and a modest increase in Antarctic sea ice coverage.

The observed effects of cryosphere reduction include modification of river regimes due to enhanced glacial melt, snowmelt advance and enhanced winter base flow; formation of thermokarst terrain and disappearance of surface lakes in thawing permafrost; decrease in potential travel days of vehicles over frozen roads in the Arctic; enhanced potential for glacier hazards and slope instability due to mechanical weakening driven by ice and permafrost melting; regional ocean freshening; sea - level rise due to glacier and ice sheet shrinkage; biotic colonisation and faunal changes in deglaciated terrain; changes in freshwater and marine ecosystems affected by lake - ice and sea - ice reduction; changes in livelihoods; reduced tourism activities related to skiing, ice climbing and scenic activities in cryospheric areas affected by degradation; and increased ease of ship transportation in the Arctic.

Arctic sea ice, Antarctic and Greenland ice sheets, global glacier mass, permafrost area, and Northern Hemisphere snow cover are all decreasing substantially, while ocean surface temperatures, sea level, and ocean acidification are rising [36].

But if West Antarctica were to lose a substantial part of its ice, then the gravitational pull would relax, and sea level would actually decrease near the ice sheet even as it spreads and increases across the global ocean.

Further, there has been an almost worldwide reduction in glacial mass and extent in the 20th century; melting of the Greenland Ice Sheet has recently become apparent; snow cover has decreased in many Northern Hemisphere regions; sea ice thickness and extent have decreased in the Arctic in all seasons, most dramatically in spring and summer; the oceans are warming; and sea level is rising due to thermal expansion of the oceans and melting of land Ice Sheet has recently become apparent; snow cover has decreased in many Northern Hemisphere regions; sea ice thickness and extent have decreased in the Arctic in all seasons, most dramatically in spring and summer; the oceans are warming; and sea level is rising due to thermal expansion of the oceans and melting of land ice thickness and extent have decreased in the Arctic in all seasons, most dramatically in spring and summer; the oceans are warming; and sea level is rising due to thermal expansion of the oceans and melting of land iceice
