By picking one specific area of only one of the spheres (surface temperatures), while it might be one piece of interesting information and it certainly it is quite true that surface temperatures have been flat at or near record high levels, focusing on this fact alone and the fact that climate models failed to have forecast it, does very little overall good if the goal is to educate the public about the bigger picture, i.e. anthropogenic climate change as an energy imbalance affecting the whole Earth energy system, including all the spheres discussed above.

The temperature at various locations in the atmosphere and on the surface of the earth is determined by the net flux of energy at that location (and never reaches true equilibrium because the energy input from the sun changes with night / day and the seasons).

A simple model for this is to consider first 2 flat plates, separated by some distance, with one plate at Earth's mean surface temperature and the other at absolute zero (OK, real universe is at ~ 3K, but it won't change the description by much).

and all working together to form a crude electric motor that deflects charged particles from the sun, which also deflect charged particles from space — while also pulling on the molten core to divert its heat to different parts of the Earth's surface at different rates... while other rocks orbiting the sun, also affect the Earth's axial tilt, particularly Jupiter, thereby changing temperature - extremes.

Evidence for changes in the climate system abounds, from the top of the atmosphere to the depths of the oceans (Figure 2.1).1 Scientists and engineers from around the world have compiled this evidence using satellites, weather balloons, thermometers at surface stations, and many other types of observing systems that monitor the Earth's weather and climate.

«Climate science» as it is used by warmists implies adherence to a set of beliefs: (1) Increasing greenhouse gas concentrations will warm the Earth's surface and atmosphere; (2) Human production of CO2 is producing significant increases in CO2 concentration; (3) The rate of rise of temperature in the 20th and 21st centuries is unprecedented compared to the rates of change of temperature in the previous two millennia and this can only be due to rising greenhouse gas concentrations; (4) The climate of the 19th century was ideal and may be taken as a standard to compare against any current climate; (5) global climate models, while still not perfect, are good enough to indicate that continued use of fossil fuels at projected rates in the 21st century will cause the CO2 concentration to rise to a high level by 2100 (possibly 700 to 900 ppm); (6) The global average temperature under this condition will rise more than 3 °C from the late 19th century ideal; (7) The negative impact on humanity of such a rise will be enormous; (8) The only alternative to such a disaster is to immediately and sharply reduce CO2 emissions (reducing emissions in 2050 by 80 % compared to today's rate) and continue further reductions after 2050; (9) Even with such draconian CO2 reductions, the CO2 concentration is likely to reach at least 450 to 500 ppm by 2100 resulting in significant damage to humanity; (10) Such reductions in CO2 emissions are technically feasible and economically affordable while providing adequate energy to a growing world population that is increasingly industrializing.

Any change in the amount of stuff in the atmosphere has no effect on the average temperature of the earth's surface because there is a balance at work.

When someone talks about climate change and warming in particular it would only make sense if they meant that the average temperature accross the earths surface is warmer than it used to be at some point in the past.
