Placing a large (presumably rotating) disk of reflective mylar in co-orbit with Venus will cast a permanent shadow on the other-wise hellishly hot planet. Eventually with global cooling the CO2 gas responsible for the runaway greenhouse effect will condense out thereby reducing not only the greenhouse effect but also the crushing atmospheric pressures. This is a phase change and may occurr quite rapidly and to a significant extent. I welcome your thoughts on this.
