The observed fact that temperatures increases slower over the oceans than over land demonstrates that the large heat capacity of the ocean tries to hold back the warming of the air over the ocean and produces a delay at the surface but nevertheless the atmosphere responds quit rapidly to increasing greenhouse gases.

Some may even still have magma oceans today, whether because they are so close to their stars that silicate vaporizes at the equilibrium temperatures or through massive greenhouse warming of their surfaces.

With the contribution of such record warmth at year's end and with 10 months of the year record warm for their respective months, including the last 8 (January was second warmest for January and April was third warmest), the average global temperature across land and ocean surface areas for 2015 was 0.90 °C (1.62 °F) above the 20th century average of 13.9 °C (57.0 °F), beating the previous record warmth of 2014 by 0.16 °C (0.29 °F).

The former is likely to overestimate the true global surface air temperature trend (since the oceans do not warm as fast as the land), while the latter may underestimate the true trend, since the air temperature over the ocean is predicted to rise at a slightly higher rate than the ocean temperature.

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).

The point about heating (adding energy) vs warming (temperatures going up) is a very good one — it might help if the scientists involved with the major temperature series people look at (GISS, RSS, etc) also produced a global surface energy change index that accounted for things like melting ice, which absorb heat without raising temperatures.

So anthropogenic land use changes (which are strongly biased toward deforestation and desertification) tend to raise the temperature observed at thermometer shelters around the world, while at the same time they tend to reduce the amount of energy available to warm the atmosphere above the surface.

Adding CO2 does not (at least not before the climate response, which is generally stratospheric cooling and surface and tropospheric warming for increasing greenhouse gases) decrease the radiation to space in the central portion of the band because at those wavelengths, CO2 is so opaque that much or most radiation to space is coming from the stratosphere, and adding CO2 increases the heights from which radiation is able to reach space, and the stratospheric temperatures generally increase with increasing height.

Global average surface temperatures are not expected to change significantly although temperatures at higher latitudes may be expected to decrease to a modest extent because of a reduction in the efficiency of meridional heat transport (offsetting the additional warming anticipated for this environment caused by the build - up of greenhouse gases).
