Forum:Do Vacuum worlds have a climate?
In the edit war over Cyrene (world), my assertion is that ice-capped worlds (Ic) do not automatically qualify for Cold or Frozen status. This is because ice-capped worlds are always vacuum worlds (atmosphere 0 or 1). It does need to be cold for ice to form. But what is the climate of the vacuum world? Say, for example, the lunar surface. Where temperatures range from 250°F to -250°F. Over a period of two weeks. So what is the climate for the moon?
In addition the Cold (Co) status indicats only the world is in the first orbit out from the habitable zone (HZ+1), which implies cold. But you can have worlds in the habitable zone orbit that are cold enough to have Ice over much of the surface, if the orbit is in the outer range of the habitable zone.
- Not really an edit war (That's a heavy handed approach...), but what is climate? Is it patterns of variation in temperature, humidity, atmospheric pressure, wind, precipitation, atmospheric particle count and other meteorological variables in a given region over long periods of time?

- Vacuum worlds might have what some may consider a hydrosphere; the Hydro implies water, but I think most of us would consider any liquid part of the “hydrosphere” for the sake of this discussion. The cryosphere would then extend to that part of the hydrosphere that is not liquid at the ambient temperature. Ssteve (talk) 10:11, 14 July 2017 (EDT)
- Does a vacuum world have a temperature? What exactly is a temperature?

- Temperature implies that you have heat. That heat for a world is normally the result of stellar radiation, or internal “volcanic” activity, although natural occurring radioactives may also be a source of said heat. That heat could conceivably provide us with an atmosphere, hydrosphere and/or cryosphere. Think of mercury (Hg), it has a freezing point of −38.83 °C and a boiling point of 356.73 °C; so depending on the temperatures… Ssteve (talk) 10:11, 14 July 2017 (EDT)
- There are two problems here. First is Vacuum world climate. Which we could beat to death easily. The second, more important, item is the confusion between the terms in the trade classes for "Climate" and "Cold" and the exact rule definition "HZ+1" (Habitable Zone orbit + 1). Most of the descriptions for the worlds in Dagudashaag do not include orbital positions. So I'm objecting to the inclusion of the "Co" trade class based upon the descriptions which don't match the specific rule.
