- There was an issue of Life magazine devoted to that exact issue. Since Life
- has tended more towards a tabloid, it has less than scientific discussions
- of the procedures, but it has some interesting commentary. If you read
- it, notice the price tag on the project. It was Life, May 1991 issue.

- I've heard, independantly several methods for generating at atmosphere (step
- one in any terraforming process). Green house gases, which involves releasing
- polar CO2 deposits using anything from space based mirrors (my favorite :-/
- to nuclear detonations. Another would be selectively kicking up the right
- dust to allow for greenhouse effects, although I have no idea how that
- would be done since particulates in the atmosphere seem to have been proven
- to cause nuclear-winter phenomenon.
-
- Any plan I have read involves work over the better part of a century to beyond
- a century.
-
- In short, the whole things looks highly unreasonable at *least*. This
- doesn't even begin to address the ethical issue of doing such a thing.
