    Regardless of the method, carbon capture is not going to work fast enough to make meaningfully change. The only realistic solution to keep earth from going runaway warming and becoming perhaps even another Venus, is to radically increase earth’s albedo to a point where the energy balans goes from +2W/m² to -2W/m², using brightening agents like sea salt for instance. In the mean time more realistic methods to manage CO2 en especially also methane levels in the atmosphere can be devised for the longer term.

      Is this something that would be combined with desalination plants for drinking water?

      I’m a fan of Lagrange Point solar shades that double as solar power collectors. Decrease sunlight and shitloads of solar energy that can be microwave-beamed to dirtside collection arrays.

        I’m also a fan of science fiction-like solutions but only in the “oh that would be so cool!” sense, not as a viable solution to the current problem of what could be a runaway greenhouse heating cycle that turns earth into “Venus the 2nd”. Keep dreaming, though because what seemed like science fiction just decades ago is becoming reality today and as a future method to regulate earths temperature it seems at least worth a look.
