I did some math (that you dismissed as worthless) that showed just how tiny a change is needed to heat the earth the small amount that we are now measuring in tempts over a decade.
It's worthless because it assumes the result.
Whether or not the man in the bed could tell the difference is not the point. He is thinking about a minute or 2 and not over the 5,256,000 min. in a decade.
It won't make any difference no matter how long he sleeps in.
On Oct 31 I posted this in an edit. However, because a power failure here somehow blocked my internet access for many hours, the edit was incomplete.
I'll post it again here for those who missed it then and add more explanation.
TtP, you assume that the air just sits there. It doesn't. There are 6 cells of air flow that ring the world like doughnuts, 3 in the northern hemisphere and 3 in the south. Air rises on one side of the dells, flows across the top of the cell, then falls down to the surface and flows across the bottom of the cell being heated, until it rises again on the other side of the cell. It is constantly going round and round. When it is rising it's because it is hotter. This carries warmer air high up in the atmosphere where it can radiate heat to space without going through saturated air that isn't above it. TtP, you've had this explained (but not as clearly) and reject it, for your strange reasons.
Look at this wiki article to see an image of the atmospheric air circulations in the diagram near the top right corner. The arrows showing the air flows are on the right side of the globe.

TtP. please click on the link to see an image of a diagram of how these 6 cells are constantly rotating, so warm air in 6 different bands is rising every day high in the atmosphere and taking the heat from the surface air with them.
So, TtP, I do not think that you realize just how much air is rising every day as those 6 bands that circle the earth are doing their thing. That air rises above most of the air and it is glowing in IR light. The air in the stratosphere has very little water vapor in it. So, most of the air above the air that just rose is not going to absorb like air at the surface does.
Again, this is a vast amount of air that is rising every day. My seat of the pants estimate of how much air is about 1% of the air each day, So, between 0.5% and 1.5% of the air each day. Even if it is 10% of that, it is still a vast amount of air.
Can you explain why you think that these new facts don't change your mind?
Because it's all the same with or without human CO2 and methane emissions.
