far out, but the experience of riding a piece of art will»; another couldn't get over the metaphor of Bernardaud's $ 9,000 porcelain edition of Jeff Koons balloon dog popping out of its display case and shattering at her feet.
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-?)
The

Be thankful that the we are insulated
from the huge volume of cold
waters that comprise the ocean, because if it ever became
far more mixed with the
surface layers we would plunge into permanent glaciation.
Re 9 wili — I know of a paper suggesting, as I recall, that enhanced «backradiation» (downward radiation reaching the
surface emitted by the air / clouds) contributed more to Arctic amplification specifically in the cold part of the year (just to be clear, backradiation should generally increase with any warming (aside
from greenhouse feedbacks) and more so with a warming due to an increase in the greenhouse effect (including feedbacks like
water vapor and, if positive, clouds, though regional changes in
water vapor and clouds can go against the global trend); otherwise it was always my understanding that the albedo feedback was key (while sea ice decreases so
far have been more a summer phenomenon (when it would be warmer to begin with), the heat capacity of the sea prevents much temperature response, but there is a greater build up of heat
from the albedo feedback, and this is released in the cold part of the year when ice forms later or would have formed or would have been thicker; the seasonal effect of reduced winter snow cover decreasing at those latitudes which still recieve sunlight in the winter would not be so delayed).
It is created by the hot salt
surface water from the Caribbean, which drives north of Scotland and
further north west of Norway to Sea of Greenland.
El Ni o an irregular variation of ocean current that,
from January to February, flows off the west coast of South America, carrying warm, low - salinity, nutrient - poor
water to the south; does not usually extend
farther than a few degrees south of the Equator, but occasionally it does penetrate beyond 12 S, displacing the relatively cold Peruvian current; usually short - lived effects, but sometimes last more than a year, raising sea -
surface temperatures along the coast of Peru and in the equatorial eastern Pacific Ocean, having disastrous effects on marine life and fishing
The ocean
surface layer is what directly matters, that contains somewhat more CO2 than the atmosphere (1,000 GtC vs. 800 GtC), but the chemical reactions in the ocean
water push the equilibrium back, so that ultimately the
surface water - air equilibrium is reached with a 1:9 partitioning between
water and air, reverse and
far away
from the 50:1.
With a heat capacity for the total atmosphere equal to ~ 3 meter of
water and an average temperature
far below the average
surface temperature there is no way you can warm Earth's
surface and oceans
from the atmosphere.
To summarise the arguments presented so
far concerning ice - loss in the arctic basin, at least four mechanisms must be recognised: (i) a momentum - induced slowing of winter ice formation, (ii) upward heat - flux
from anomalously warm Atlantic
water through the
surface low ‐ salinity layer below the ice, (iii) wind patterns that cause the export of anomalous amounts of drift ice through the Fram Straits and disperse pack - ice in the western basin and (iv) the anomalous flux of warm Bering Sea
water into the eastern Arctic of the mid 1990s.
The processes include
water from melting on the
surface of the ice sheet to flow down into crevasses and widen them
further.
They
further suggest that irrigation
water derived
from surface sources may infiltrate into aquifers, removing 0.40 to 0.48 mm / yr of sea level equivalent, based on the same assumption as for seepage
from reservoirs.
A
far grander feature of the Earth's
surface heat circulation was recognized in the 19th century when scientists tracked down the fact that
water hauled up
from the deeps, anywhere in the world, is nearly freezing.
All that is needed is to add heat carried upwards past the denser atmosphere (and most CO2) by convection and the latent heat
from water changing state (the majority of heat transport to the tropopause), the albedo effects of clouds, the inability of long wave «downwelling» (the blue balls) to warm
water that makes up 2 / 3rds of the Earth's
surface, and that due to huge differences in enthalpy dry air takes
far less energy to warm than humid air so temperature is not a measure of atmospheric heat content.
Accordingly, upwelling of
waters acidified by anthropogenic CO2 has led to a
further decrease in
surface pH, as reported in the eastern Pacific Ocean along the west coast of North America,
from central Canada to northern Mexico, where shoaling of the layer of seawater undersaturated with aragonite increased the frequency and magnitude of coastal acidification associated with upwelling events (Feely et al. 2008, 2010).
The
water vapor feedback mainly results
from changes in humidity in the tropical uppertroposphere (2), where temperatures are
far below that of the
surface and the vapor is above most of the cloud cover.
The 2008 K&T cartoon gives a NET upward radiation flux
from the
surface of 33w / m2 with a downward adjustment to
water vapour to 76w / m2 and conduction to 16w / m2 but the point holds; that point is more net heat is leaving the
surface through methods other than radiation, particularly
water; that to me means 2 things;
water is a dominant mover of heat compared to CO2 and the sun's 168/166 w / m2 is a
far more dominant heater than CO2 backradiation.
The IPCC has already concluded that it is «virtually certain that human influence has warmed the global climate system» and that it is «extremely likely that more than half of the observed increase in global average
surface temperature
from 1951 to 2010» is anthropogenic.1 Its new report outlines the future threats of
further global warming: increased scarcity of food and fresh
water; extreme weather events; rise in sea level; loss of biodiversity; areas becoming uninhabitable; and mass human migration, conflict and violence.
These new Rossby waves begin to draw cooler
