If a larger mass of warm air has to pass through it, more energy is transferred, through the evaporator's fins (so that even the evaporator's design and, in particular, its exchange surface play an important part) from the air to the liquid refrigerant allowed inside it by the TEV or orifice tube so it expands more and, along with the absolute pressure inside the evaporator, the refrigerant's vapor superheat (the delta between the boiling point of the fluid at a certain absolute pressure and the temperature of the vapour) increases, since after expanding into saturated vapour, it has enough time to catch enough heat to warm up further by vaporizing the remaining liquid (an important property of a superheated vapour is that no fluid in the liquid state is carried around by the vapour, unlike with saturated vapour).

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).

One is that the mechanism for the GHG warming is that the radiated energy from the air is absorbed by the GHGs to heat the GHG molecule to 900 + degrees, then the energy is released within microseconds and a few centimeters back to the air by collisions with the air, to return the air & GHGs to equilibrium temperature.
