I have a plan for Venus.

1. We put a bunch of mirrors at the Venus-Sun Lagrange point #1. Reflect light away from Venus. Cool it down until the atmosphere freezes. (This is a 1000 year project.)
2. Once the surface pressure is down to 1 Bar or 14.7 PSI or 101 kPa or whatever, start building chemical plants on the surface to convert those puddles of liquid nitrogen and frozen blocks of CO2 and sulfuric acid into solid minerals, so the air pressure won't rise when the heat is turned back on.
3. Turn the heat back on, by turning some of those mirrors sideways to the Sun.
4. Introduce life. Hydrogen from sulfuric acid and oxygen from CO2 make water. Chemical plants from step 2 have made some fertilizer. Plant some plants. Water them.
5. Bring in the people.

It might take 2000 years total, but we can remake Venus in Earth's image.
