BUT DON'T EVER DO THIS!!!!!

I do agree with you to some extent on both points.

I remember a great documentary about how the worldwide no-fly moment (caused by Osama Bin Laden), resulted in all the metrics of climate change to blip up. Evaporation rates, temperatures, and so on. It was the lack of jet-fuel exhaust in the sky that was the major contributing factor. Apparently, the filth in that level of stratosphere acted as a reflector prior to the energy entering our environment. It seems we need a carbon negative technology to emerge that cleans the lower air before we clean the upper air. One energy plant in Europe is doing this. Superheating wood chips to burn the natural gas that they give off resulting in pure charcoal waste that they plow into soils of farmland.

I'm not sure what you mean by a heat engine for Earth. Their is some evidence that we will have a population reduction worldwide. Our existence requires the consumption of resources and all our methods require byproducts that trap solar insolation. Because our growth is exponential, we're fucked. We don't have the ability to put the greenhouse gasses/particles up into the stratosphere, so we cant use our waste to shield us from our waste.
