In the study, the researchers use an ice - ocean model created in Bremerhaven to decode the oceanographic and physical processes that could lead to an irreversible inflow of warm water under the ice shelf — a development that has already been observed in the Amundsen Sea.

«The fresher and warmer the water is, the less dense it will be, and the more it will expand and take up more space — and that leads to rising sea levels,» Macdonald said.

That leads them to suggest that the concentration of lumps may have come about when a large number of whales died and then sank to the sea floor, where the carcasses quickly decomposed in the warm, shallow waters but the ambergris — which on its own typically floats — was buried and preserved.

They found that stabilising the increase at 1.5 °C would lead to seas rising less, and more slowly, than if the planet was allowed to warm by 2 °C.

Deep - sea oil exploration will probably release future spills, Solomon says, and global warming could destabilize large undersea deposits of frozen methane, leading to local ocean acidification or oxygen depletion (SN 7/31/2010).

If global warming leads to an increase in monster storms, MacAyeal adds, then the entire Antarctic ice skirt could be in jeopardy: Larger sea swells could pulverize its huge icebergs and floating ice shelves.

A new modeling study to be published in the Journal of Climate shows that stronger polar winds lead to an increase in Antarctic sea ice, even in a warming climate.

Since so much of the ice sheet is grounded underwater, rising sea levels may have the effect of lifting the sheets, allowing more - and increasingly warmer - water underneath it, leading to further bottom melting, more ice shelf disintegration, accelerated glacial flow, and further sea level rise, and so on and on, another vicious cycle.

On the high end, recent work suggests that 4 feet is plausible.23, 3,6,7,8 In the context of risk - based analysis, some decision makers may wish to use a wider range of scenarios, from 8 inches to 6.6 feet by 2100.10,2 In particular, the high end of these scenarios may be useful for decision makers with a low tolerance for risk (see Figure 2.26 on global sea level rise).10, 2 Although scientists can not yet assign likelihood to any particular scenario, in general, higher emissions scenarios that lead to more warming would be expected to lead to higher amounts of sea level rise.

But it remained unclear exactly which came first: melting ice and warming seas released more CO2 or more CO2 led to melting ice and warming seas.

If the Earth warms by just two degrees Celsius, the scientists predict it will lead to a sea level rise of 4.6 metres for Copenhagen.

Global warming of four degrees Celsius could, they say, lead to a sea level rise of 7.5 metres, submerging the homes of 391,000 residents.

But there is also no extrapolation over sea ice as far as I can tell, so that omission could also lead to an underestimate of recent Arctic warming.

This could be do to changes in ocean circulation, and warming waters reaching the grounding lines for ice shelves in Arctic and Antarctica, leading to non-linear increase in melting and sea level rise, impossible to avoid on our current path.

Increased temperature leads to increased evaporation from the sea, and thus to higher absolute humidity (assuming fixed relative humidity), and since H2O molecules are even more effective infrared absorbers than CO 2 molecules, the warming trend is reinforced.

There are steps leading down to a dock and the sea — the water in this natural reserve is warm and filled with colorful fish.

Unprecedented warm waters off the Pacific coast over the past two years have led fish that marine mammals feed on to move to colder waters — making it difficult for seals and sea lions to nourish themselves, let alone feed their pups.

Much of the recent sea ice loss is attributed to warmer sea surface temperatures with southerly wind anomalies a contributing cause [Francis and Hunter, 2007; Sorteberg and Kvingedal, 2006], with thermodynamic coupling leading to associated increases in atmospheric moisture.»

All of this reinforces the idea that the basics remain clear, including that a warming world will have less ice, and that will lead to higher seas.
