So, if you have two identical glass greenhouses with thermally isolated mercury thermometers at equilibrium in the sunlight [One with Air at Press =P, and the 2nd w / CO2 at Press =P], and you close the blinds — you will see the thermometer in the CO2 greenhouse retain its temperature longer — not because of any «global warming» type effect, but simply because Air conducts heat to the walls of the greenhouse better than Air does.

Inside a greenhouse, hot air can rise only so far; so the cold layer of air on the bottom can get heated too.
Basically what we are saying is that normal greenhouse is based on having less thermal mass to heat than the atmosphere as whole due to seperation from that atmosphere, and to a lesser extent on insulation due to the air not moving as much.
So, if you have two identical glass greenhouses with thermally isolated mercury thermometers at equilibrium in the sunlight [One with Air at Press =P, and the 2nd w / CO2 at Press =P], and you close the blinds — you will see the thermometer in the CO2 greenhouse retain its temperature longer — not because of any «global warming» type effect, but simply because Air conducts heat to the walls of the greenhouse better than CO2 does.

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).
But the air conditioners absorb all the extra heat and the greenhouse stays at a comfortable 27C.
Thus it is very difficult for the ocean to transmit heat by long wave radiation into the atmosphere; the greenhouse gases just kick it back, notably water vapor whose concentration is proportional to the air temperature.

A side point here is that the ocean loses heat by radiation to both the air (thanks to greenhouse gases) and to space, and to the atmosphere by direct conduction and this, via convection and radiation, ultimately to space.
John Carter August 8, 2014 at 12:58 am chooses to state his position on the greenhouse effect in the following 134 word sentence: «But given the [1] basics of the greenhouse effect, the fact that with just a very small percentage of greenhouse gas molecules in the air this effect keeps the earth about 55 - 60 degrees warmer than it would otherwise be, and the fact that through easily recognizable if [2] inadvertent growing patterns we have at this point probably at least [3] doubled the total collective amount in heat absorption and re-radiation capacity of long lived atmospheric greenhouse gases (nearly doubling total that of the [4] leading one, carbon dioxide, in the modern era), to [5] levels not collectively seen on earth in several million years — levels that well predated the present ice age and extensive earth surface ice conditions — it goes [6] against basic physics and basic geologic science to not be «predisposed» to the idea that this would ultimately impact climate.»
The notion of an H2O positive feedback (which probably is present on a clear day) is squashed by this process.While warmer air can hold exponentially more water vapor, presumably increasing greenhouse effects (an process the IPCC hangs its collective hat on), it is also this exact same property that vastly improves the chances of convective and phase change heat transport by thunderstorms.
As the ocean and airs warm, these carbon stores release causing a massive spike of additional greenhouse gasses to hit the atmosphere and setting off ever - more - rampant heating.

In the real greenhouse which is our whole fluid real gas atmosphere which has volume, weight and attraction and is subject to gravity, the some 99 % nitrogen and oxygen dry air is what acts as a blanket keeping the Earth's heat from escaping too fast before the Sun again heats the surface, without water the Earth's temperature would be 67 °C not 15 °C — think deserts.
Solar energy heats air inside the greenhouse, which can then be vented into the home through an open door or windows.
