"We are all repositories for genetically-encoded information that we're all spreading back and forth amongst each other, all the time. We're just lousy with information."
- Neal Stephenson

| Using the greenhouse effect to terraform a planet or moon. |
Interesting use of the greenhouse effect for terraforming.
| Ganymede was straight ahead, almost, and growing all the time--and
here was a funny thing; Callisto was silvery, like the Moon, but not as
bright; Io and Europa were bright orange, as bright as Jupiter itself.
Ganymede was downright dull! I asked George about it; he came through, as usual "Ganymede used to be about as bright as Io and Europa," he told me. "It's the greenhouse effect--the heat trap. Otherwise we wouldn't be able to live on it." I knew about that, of course; the greenhouse effect is the most important part of the atmosphere project When the 1985 expedition landed Ganymede had a surface temperature a couple of hundred degrees below zero--that's cold enough to freeze the milk of human kindness! "But look, George," I objected, "sure, I know about the heat trap, but why is it so dark? It looks like the inside of a sack." "Light is heat; heat is light," he answered. "What's the difference? It's not dark on the ground; it goes in and doesn't come out--and a good thing, too." |
