Best result probably looks like Mars. Worst Venus. Either way, survival looks like trying to scrub the planet of any evidence you were ever there as you flee the solar-system in shame, or starting an Empire premised entirely on keeping others away from the home system, for fear of being outed. Maybe both.

Someone doesn't understand thermodynamics.
The first sentence of the article answers the rhetorical question:
Kevlak: Science Unit Blarkblark, your report on the Sol system?
Blarkblark: Eight planets circle a mainline yellow star.
Kevlak: So nothing interesting then?
Blarkblark: Well, there is something that confuses me.
Kevlak: Elaborate.
Blarkblark: The third planet harbors life.
Kevlak: That's hardly unusual.
Blarkblark: The dominant species on this planet...
Kevlak: Get on with it.
Blarkblark: They made their planet hotter, then decided they didn't like it hotter, so they built devices to make their planet colder.
Kevlak: Seems reasonable enough.
Blarkblark: But they never stopped what made it hotter.
Kevlak: Doesn't that act against their purposes?
Blarkblark: It gets stranger. The devices also make their planet hotter.
