Unfortunately
air temperatures are the dataset of most interest to us
since that is where we live.

temperatures offer less opportunity to keep windows open, the drier
air inside the home can start to feel stuffy.

@Paulster2: I believe the

temperature correction taking place here.
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).
Turning
air recirculation on makes the evaporator cool down to the required
temperature even faster and easier
since all it has to cool is already cooled
air.

Air temperature increases similar to those observed aloft
since 1960, amplified by associated increases in humidity, account for a significant portion of the enhanced ablation leading to this strongly negative mass balance, but the exact proportion is highly uncertain because of the short span of energy and mass balance observations.
As far as this historic period is concerned, the reconstruction of past
temperatures based on deep boreholes in deep permafrost is one of the best past
temperature proxies we have (for the global regions with permafrost — polar regions and mountainous regions)-- as a signal of average
temperatures it's even more accurate than historic direct measurements of the
air temperature,
since the earth's upper crust acts as a near perfect conservator of past
temperatures — given that no water circulation takes place, which is precisely the case in permafrost where by definition the water is frozen.
From the abstract: «Despite ongoing increases in atmospheric greenhouse gases, the Earth's global average surface

since relative humidity remains roughly constant at the ocean surface and the
air's capacity to hold water increases with
temperature, relative humidity will actually decrease over land, particularly as one enters the continental interiors.
The argument isn't actually as firm a constraint as generally believed,
since the infrared radiative cooling of the atmosphere is affected by the
temperature difference between
air and the underlying surface, which can adjust to accommodate any amount of evaporation Nature wants to dump into the atmosphere (as shown in Pierrehumbert 1999 («Subtropical water vapor...» available here)-RRB-.
