Rather prefer space based foil-solar sail ice cap shielding and artifically growing glaciers near south and northpole..

  Or, direct air carbon capture. Getting to net zero would cost ~ $1 / gallon of gasoline (and equivalent for other things that emit.) I think we should be paying ~ twice that, minimum. It's far less risky than trying to block out the sun.

      Seaweed mostly floats. Dead seaweed gets degraded by bacteria (just like everything else) and the carbon returns to the atmosphere.
