I have been brainstorming a possible last-ditch approach to dealing with the looming climate crisis. It's obvious now that we're already well past the "critical point", where the warming from humanity's emissions have given the process enough momentum to make it self sustaining.

I think now we're at the point we should shelve carbon cutting measures indefinitely and instead focus on managing the Earth's climate directly, by forcibly increasing it's albedo. I propose that we build massive nuclear powered blended-wing-body airplanes that spray millions of gallons of filtered seawater in the lower stratosphere which then immediately turns to enormous clouds of sunlight-reflecting ice. When the plane runs out of water it lands in the ocean again to refill its tanks with more filtered seawater for another spraying mission. It will repeat this process until it's reactor fuel needs replacing. The overall design of these special "Jötnar" airplanes would be similar to pic related, and have onboard closed-cycle nuclear reactors. Unlike the experimental nuclear-powered bombers of the 1960's (which were ultimately never built), where heated air from a reactor was used to turn a turbine compressor in place of combusted jet fuel, the Jötnar planes will have their reactors serve as generators for an array of electrically driven propellers. The planes would perform their spraying missions almost exclusively far out at sea, both to minimize risks of fallout in the event of a crash, and to reduce the amount of heat absorbed by the ocean from sunlight.

The Jötnar airplanes would be enormous, similar to the obscure Lockheed CL-1201 airborne aircraft carrier proposal. If enough of these machines are put into operation together, they can potentially slow or even halt the runaway warming process.

I know this would ultimately be a trillion dollar (at least) effort, but I think it's a good idea to at least have on the drawing board if things really get serious in the future.

How many of these airplanes would we need? At least perform a rough calculation to investigate whether it could effective.

I imagined the first prototypes being dramatically scaled-down land-based conventional jets to test the technology and ice spreading effects which will be used for these calculations.

From there we'll work on airborne nuclear propulsion, seawater filtration systems, and amphibious hull designs.

Too much money and resources. I doubt those with the money care enough to give it all away to build some planes.

>international (people) response
people already whine about "chemtrails", imagine if suddenly a megacorp turned around and started spraying shit into the air, people will be outraged and conspiracy theorists will come out of the woodwork. regular cell towers are all ready being burned because people think they are 5g towers, so imagine the guerilla response to these planes

>international (government) response
do you really expect countries and united orders of governments to allow such planes into international airspace to do such tasks?

>global effect
the climate problem is a big problem, sure, but animals are adapting slowly and it has changed the face of our earth already. what we need is a measured response to slowly drive the earth back on the right track, not a sudden jolt, otherwise you will flip the entire train. imagine using this to suddenly drop global temperatures. it would have devastating affects on worldwide climates, species and economies

You could just fix climate change with a trillion already. If we really were forced to alter the atmosphere to lower the temperature then you would use conventional planes to spray chemicals instead of some kind of meme magic plane making clouds.

Chinese people are already living on half the energy than you wasteful americans, Indians on one fourth. You are the real problems.

China burns as much coal as the rest of the world combined. Over half their railroad rolling stock is in moving coal. They build new coal plants alongside the renewable.

Per capita is meaningless. When most of the pollution is tied to state controlled export.

You are on point with the albedo thing, but think surface mirrors or building everything whiter.

You can spray water of tower on boat, and have some enthalopy to get loose, up to cold itself and down again.

You can power boat with heat from sea water itself. You just spray thin aerosol from carbon tower on top of a large area boat and have multiple boats like that.

You put high ultrasound resonance there, which will break a lot of water at once into thinniest aerosol, and it will absorb heat from atmosphere.

By spraying up layer you solve nothing much more. I know it's colder there, but usually heated water gets there, so solution is just to get heat in water that's in air and it'll find itself.

Yes. And do that just before sunrise so that the vapour will dissipate before nightfall, otherwise you trap heat back on earth.

Environmentalists threw a fit when it was discovered someone was fertilising the sea with iron. Any improvement in CO2 conversion to O2 is badthink. The idea, it seems, is that we can only gain redemption by returning to the stone age.

Noticed there is NO change in the atmospheric CO2 trend even though the traffic has dropped like a rock?

This is a stupid and suicidal solution. It means less sun which in turn decrease food production drastically and therefore widespread famines. Also how would we reverse the process if we needed to?

Incorrect.

Cloud seeding is only a temporary solution because clouds will eventually start to dissipate faster from increased heat.

Nice strawman.

There is a small change, which is expected since a short term change in our emissions will not have an immediate effect on longer term feedback loops that are already running.

OK, and? The issue is emissions.

>Per capita is meaningless. When most of the pollution is tied to state controlled export.
LOL, so the state is purely to blame for the export, but just ignore the importers.

No, per capita is very important. More people means more emissions. It's like saying China has an obesity issue because China eats more food than the US.
