I don't know how feasible this idea is. I guess that is part of my question. (And I'm not advocating; calm down.)

Reading an article in The New Yorker... It describes the importance of feedback loops, including the Atlantic Meridional Overturning Circulation (AMOC, pronounced "ay-mock").

It describes the water flow from south to north, with the heavy cold salty north water sinking and the warmer south water being drawn north. At full strength, total flow is 20 "sverdrups", 100 times flow of Amazon. Variations in the flow (and salinity) cause variations in cooking/heating.

Anyone know more about this? Ever heard of Geoengineering proposals dealing with the AMOC?

I'm writing my thesis on the governance of SRM, and I've noticed some debate on the approach to take. Some advocate for a top-down strategy, arguing that SRM's global effects require centralized governance rather than relying on individual countries as the effect will be global. Conversely, others suggest starting with the scientific community self-regulating and pressuring nations to enact laws, eventually leading to a cooperative international governance structure. I'm curious to know which approach you support more?

In some countries, mirrors or high albedo materials can be placed on top and sides of cars reducing the absorbed heat, thereby reducing the need for air conditioning, which would slightly reduce the carbon released and it would also be surface albedo modification. Not easy to implement though

I am wondering if carbon capture and storage could be applied to burning something like Miscanthus giganteus and that would be a viable and scalable form of negative emissions?

It seems, that some plants are already quite efficient at carbon sequestration so burning them and storing the carbon would be easier than building direct air capture technology? Plus, these plants also store a significant amount of carbon by themselves in their underground roots regardless of capture.

Is it something that is considered seriously already? I don't know enough about the economics, but Miscanthus giganteus seems to have a high energy density per acre (comparable to renewables) so that could make the economics of carbon capture viable?

It would need of course to have advanced locks and rail road for the contents but in my theory it would be a catalyst to lift Africa, remove any dependency on Russian gas/oil ? Thoughts ?

Not exactly climate-change related and admittedly a very green and not too well thought out idea. The presence of Saharan dust over the Atlantic interferes with the production of tropical storms. I wonder if it would be possible to easily kick up dust in the Sahara to enhance the amount of dust flowing westerly towards the Caribbean and Southern U.S. Are there some human land-use practices that are usually avoided because they create dust that would enhance dust over the Sahara ? (in a responsible way, of course)

The ground track of a geosynchronous sunshade would be a north-south aligned narrow figure of 8. But the path of the shadow would be, I think, an arc. Suppose the maximum northern excursion was to 50 degrees north and 100 degrees west, the Kansas Nebraska border about halfway across those states. Then the arc might go from Miami to Nebraska to San Diego, maybe.

If the shadow were big, like maybe the size of Rhode Island, it would have a big impact on the area under the arc. Solar panel power reduced, drastic temperature swings, traffic accidents in the daytime darkness. Property values maybe lower, or maybe higher if the daily temperature drop helped agriculture.

How could this be prioritized?

New Startup in the Swiss wants to use Jets to spray Iron over the Sea. Why do we not add more Iron in Ship and Airplane fuel?

Shower thought... what about instead of putting a giant, hard to build, hard to maintain physical shade, what if we just shot out some compressed gas or particulate aerosol and let it decompress?

Even if it had a temporary affect, maybe 1-2 launches per year keeps up the density or something?

I feel like if I had enough time I'd whip out some old physics textbooks.. but has this idea been raised before?
