The whole greenhouse analogy is flawed. Greenhouses get hot because light heats the solid matter inside the greenhouse. Air inside gets warmer by contacting (conduction) the solids. The warm air rises but meets a physical barrier only a few feet away. So, a major element of the earth’s atmosphere, large scale convection, is prevented in greenhouses. How do you cool a greenhouse? Open vents in the top and allow convection to take place. The earth does not have anything approaching a glass ceiling.
