Life there is sustained by the intermittent rain of dead organic
matter from the surface waters.

The first is to emphasize your point that degassing of CO2
from the oceans is not simply a
matter of warmer
water reducing CO2 solubility, and that important additional factors include changes in wind patterns, reduction in sea ice cover to reveal a larger
surface for gas escape, and upwelling of CO2
from depths consequent to the changing climate patterns.
In that case it does not
matter how the
water is heated but simply the temperature of the layer of
surface water down to a few multiples of the inverse of the IR absorption coefficient which is I think varies
from around a few cm to less than 1 mm with increasing wavelength.
The system is vulnerable because even a relatively small decrease in
surface salinity prevents
water - no
matter how cold it is -
from sinking.
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.
As to the absorption of long - wave radiation
from the earth's
surface, while it may be true that carbon dioxide and
water together do absorb certain frequency ranges of that radiation, I don't think that that
matters a whole lot because most of the heat
from the
surface is transported to the top of the troposphere by conduction, convection and latent heat of vaporization of
water during the day.
The AGW Greenhouse Effect energy budget has taken out, excised, the real heat
from the Sun which is capable of heating
matter and does reach the Earth's
surface to heat land and
water and replaced it with the claim that visible light heats the
matter of the Earth's
surface, this is impossible in the real world.
We don't have visible light saunas, we have thermal infrared saunas; we don't have visible light heaters to heat our homes, we have thermal infrared heaters heating
matter directly, just as the real thermal infrared direct
from the Sun heats the
matter on the Earth's
surface directly; heats
water of the oceans, heats the land, heats it so intensely at the equator that it gives us our HUGE and dramatic WINDS flowing
from the equator to the poles and back again.
The increased albedo
from melting arctic ice should not
matter very much, but the newly exposed cold
surface water might absorb extra carbon dioxide, acting as a negative feedback on the whole system.
Light waves can be reflected / scattered, absorbed, refracted, or transmitted to pass through
matter unchanged and different materials will have different effects in these encounters; high energy light waves get scattered in our atmosphere
from encounters with dust,
water vapour, molecules, etc. as the white light hits the rough
surface composed of these, so we have a blue sky for example, while the longer IR gets absorbed by
water and earth, on a smooth
surface such as glass or still
water these high energy lights get reflected, angle of incidence equal to, and some pass through to get reflected or scattered at the next
surface, think rainbow.
