It is actually quite simple. Instead of producing less greenhouse gases. We cool Earth down.
High up there, there is a layer of very, very cold air. At the top of Troposphere, about 12km above the sea level, the temperature is about -10°C to -60°C. Mesosphere, 50km above sea level, gets to -90°C.
If we pump the cold air, from either the top of Troposphere or Mesosphere, down fast enough. It can be below freezing when it reaches sea level.
It can freeze the surface sea water and produce ice: a fresh water by-product from the solution to global warming.
To create the down draft, we need a big downward spiral like a funnel. As the funnel narrows at the bottom, the air speeds up and the momentum carries itself. The top of the funnel does not need to reach 12km, the spiral vortex behaves like a sucking machine. To do this, we need air moving equipment — essentially many big fans — to generate the man-make tornado, but blowing downward instead of up.
OK, it is silly to have big fans suspended in the air blowing to nowhere. There are engineering difficulties and may kill too many birds or even airplanes (although they have radars). Alternatively, we can apply energy to create this vortex.
The idea is simple, but a bit far-fetched. We lay a ring of heating elements in the ocean. As the temperature near the surface rises, the air flows up. When it hit the cold air up in the Stratosphere, it cools and goes down. The rising air forms a cylindrical curtain and restricts the down draft in the middle. By varying the temperature at the ring, I might be able to create a downward vortex. With enough heat, the vortex can reach high enough. As long as there is more coldness down than the heat from the ring, Earth cools down with this. Again, fresh water will be a natural by-product.
Brilliant. I might say. Stupid, say the geo-physicists.
