Beyond the surface mechanics though, each machine is also more or less susceptible to specific types of damage, be it fire, ice, electricity, or the narrative - connected «corruption.»

Of course, during winter as the water freezes on the surface, the resulting sea - ice is less dense, so it floats.

One possibility is that the deep melt is brought to the surface somehow, in which case the surface waters actually get colder again, leading to much greater summer ice rather than less.

Would it be the Larsen taking 2 years to sail through the NW passage, instead of less than a week now a days???

Are there measured areas where the ice surface altitude is less than this ratio?

Combined climate / ice sheet model estimates in which the Greenland surface temperature was as high during the Eemian as indicated by the NEEM ice core record suggest that loss of less than about 1 m sea level equivalent is very unlikely (e.g. Robinson et al. (2011).

So that, while the surface area may be greater this year compared with last year, the volume of ice in the Arctic this year is probably already less than at the same time last year.

That's because increasing clouds will cut the direct SW energy before it arrives at the surface, thus less energy will actually be trapped by the interactions between the sea - ice and the clouds above.

Additionally, the less sea ice covers the surface of the ocean, the more sunlight is absorbed by the water, which scientists warn could accelerate the Arctic's warming.

Ice is highly reflective, while the underlying ocean surface is far less reflective.

Maximum warming occurs over the surface during winter while less surface warming is found in summer when heat is being used to melt sea ice.

For some unexplained reason there have been a large number of coronal holes on the surface of the sun, in low latitude positions during solar magnetic cycle 24, however due to the reduction in the solar wind density the solar wind bursts have less effect on cloud modulation which explains why there has suddenly be an increase sea ice in the Antarctic, a recovery of sea ice in the Arctic, and an inhibiting of the formation of El Niño events.

I find it interesting to see that the HOC is increasing the strongest around antartica in the deep while the see ice area (not volume) shows slight increase and surface temperature is more or less constant.

The loss of large areas of ice on the surface could accelerate global warming because less of the sun's energy would be reflected away from Earth to begin with (refer back to our discussion of the greenhouse effect).

The simplistic argument being that less solar energy will be reflected by water compared to an ice or snow surface leading to further warming and thus ever more melting.

When oceans get cold, and the surface of polar waters freezes, it snows much less and the sun takes away ice and limites the lower bound of temperature and sea level.

The reason, Werner said, is because the loss of snow and ice makes the earth's surface less reflective, meaning solar radiation — or heat — is absorbed in greater amounts by the exposed dark ocean or tundra.

Lukovich and Barber: The results from an investigation of stratospheric circulation in winter and spring, and comparison of summertime surface winds and SLP with vortex splitting and minima in sea ice extent composites suggested that the September, 2009 ice extent would be comparable to or less than the September ice extent minimum in 2008, based on dynamic considerations.

Pay special attention to how the direction of the relationship changes around 0C as ice melts and the surface becomes less reflective.

Serreze says if warm air and sea - surface temperatures persist, the 2017 maximum could set yet another record for even less sea - ice cover.

In one of the troubling feedback loops of the changing climate, dark ice is partially caused by the warmer Arctic summers climate change has brought us: More warmth means less fresh snowfall to cover areas of accumulated sediment, changes to the shape and size of ice grains that make them less reflective, and more liquid near the surface.

The mechanisms that lowered surface pH to 8.3 - 8.4 during the Last Ice Age is a matter of considerable debate, but clearly more carbon was being sequestered at depth and less carbon was being pumped to the surface.

If heating at the surface is dangerous to societies and ecosystems and land ice and SLR and so on and so on then instinctively it seems that deep in the ocean is a less worrying place for it.

(16) While it would necessarily take many thousands of years to melt the great ice sheets, they had realized that meanwhile the atmosphere and the ocean surface waters, which were less massive, could be fluctuating on their own.

If the ice shelves are removed, the feeding glacier is less buttressed and will accelerate for a period and draw down its surface profile.

Second, and less important but still rather spectacular, was the melting of virtually every square inch of the surface of this ice sheet over a short period of a few days during the hottest part of the summer, a phenomenon observed every few hundred years but nevertheless an ominous event considering that it happened just as the aforementioned record ice mass loss was being observed and measured.

With ice cover shrinking in the Arctic during the summer months, less sunlight is reflected off the icy surface, which means the ocean absorbs the sunlight instead.

An increase of solar radiation will lead to a rising temperature, to an extent depending on the amount of ice on the surface; an ice cover will reflect much of the extra radiation away, causing less heating, until eventually the heating is sufficient to melt the ice.

Cold water sinks readily in polar regions, as the surface water tends to be closer to freezing, as well as being fresher from ice melt, and therefore less dense than the inflowing currents, which are in turn are rendered more saline by the fresh water freezing out.

Since full melt of all grounded ice is equal to over 70 metres of sea level rise, then it follows that there is the equivalent volume of 70 metres of ocean surface that is currently existing as ice at less than zero C.

So, because ponded ice reflects less of the solar radiation, there is more heat available to melt the surface of the ice,» said Daniel Feltham, a researcher at the Center for Polar Observation and Modeling at the University College London, and co-author of the study, in an email.

Snow and ice reflect more sunlight than bare ground, meaning less solar radiation is absorbed by the surface.

Global warming is predicted to give us longer, hotter summers, drier conditions across the US, more record temperatures, thinner arctic ice, and having it cover less surface area of the Earth.

Because meltwater is less reflective than ice, the surface of the ice sheet is already absorbing more sunlight — previous research found that the reflectivity of the Greenland ice has dropped by 6 percent in the last decade, according to an Ohio State University release on the new research.
