How about the very mechanism of warming shows AGW theory to be a failure.
This nonsense again? Guess I'll just have to debunk same as I did before.

This is the temperature profile of most spots in the ocean. Note the vertical scale is sort of logarithmic.
The bulk of solar energy penetrates deeply and warms the water. Convection causes warmer water to rise, so the oceans get warmer as they get shallower.
However, that trend reverses at the skin layer. The atmosphere is usually colder than the ocean below, so the ocean at the surface loses heat to the cooler atmosphere, which lowers the temperature of the skin layer by about 1C.
The amount of heat flowing out the oceans, from combined conduction and evaporation, depends on the delta-T across that skin layer. Heat conducts from hot to cold, linearly proportionally to the temperature difference. With more of a temperature gradient, more heat flows out of the oceans. Less of a gradient, less outflow.
Enter the IR radiation. It heats the skin layer, decreasing the delta-T across the skin layer, so less heat flows out of the oceans. The IR doesn't heat the deeper ocean directly. It reduces the heat flow out of the deeper ocean, so more heat stays in the deeper ocean, so the IR indirectly warms the deeper ocean.
UV radiation penetrates 500 meters deep into the ocean to warm it. The oceans govern the heat of the planet. Long wave IR (the claimed engine of warming) is not capable of penetrating the skin of the water, thus the theory fails its very first test.
Yes, we get it. You think conservation of energy is a suggestion, not a law, and you can ignore it whenever convenient for you. In your world, the backradiation strikes the ocean ... and then the energy just disappears into some magical mystery dimension. You ought to write a paper on the physics behind that.
