What happens at the «top of atmosphere» — the level where outgoing radiation leaves for space, not itself a very easy concept — is the restoration of equilibrium, the increase in temperature that, through Helmholtz - Boltzmann at the Earth's brightness temperature 255K, restores the balance between incoming and outgoing energies.

Even if you leave climate science completely out of it and just measure extreme temperatures, the statistical record of global temperatures shows that three - standard deviation events have increased from 0.25 % of the time (from 1951 - 1980) to 10 % of the time now.

Because CO2 makes the atmosphere more opaque to infrared radiation, and because the atmosphere gets colder as you get higher, the «effective radiation temperature» of the infrared radiation leaving the earth is made colder by increasing CO2 (fewer Watts per square meter of infrared radiation leave the top of the atmosphere).

Thus, if the absorption of the infrared emission from atmospheric greenhouse gases reduces the gradient through the skin layer, the flow of heat from the ocean beneath will be reduced, leaving more of the heat introduced into the bulk of the upper oceanic layer by the absorption of sunlight to remain there to increase water temperature.
