And then you get a world bathed in eternal darkness until you control it's greenhouse gas atmosphere?
I think it would be easier to just limit greenhouse gas emissions on earth.
Your point works pretty well considering that Venus has a a dense atmosphere unlike Mars.

The same technology could be used to reduce gw on the earth: 1. an orbiting sunshade 2. putting something in the atmosphere that makes it more reflective, like sulfur dioxide I wonder how big a sunshade would need to be to reduce temps by, say, one degree. A specific location could be shaded by putting the shade in geosynchronous orbit. To finance the sunshade, put a Starbucks or Coca-Cola logo on it.

- Tuna-Fish 3y agoThe kind of sunshades that are reasonably being proposed are not large enough to see from the earth without a very powerful telescope. A single giant megaproject sunshade is not feasible. But it is possible to make many smaller ones, each diminishing insolation by just a few fractions of a percent.
