Sorry, you seem confused on this point.
All the heat that reaches earth from the sun, all the heat that originates inside the earth, and all the heat generated by all human activities combined eventually radiates out into space. The rate at which it does this is regulated by several atmospheric components, the chief of which is carbon dioxide (CO2). If the atmospheric CO2 is reduced, the amount of "greenhouse effect" is reduced, and the global temperature will drop. If the amount of CO2 in the atmosphere rises, as it has done gradually since the beginning of the Industrial Age, then it traps mor of the heat radiation and cause the global temperature to rise.
Air Conditioning powered by solar energy is net neutral. It affects nothing, because it does not emit CO2.
And to the specific complaint here, I agree, Disney widely uses air curtain technology on busy doorways in high traffic areas that is actually competitive with conventional doors for keeping the heat out, or the heat in, as the case may be at different times, in different parts of the world.
