:Congrats RobertWDP, I love when you follow the rules like that, we want respectable contributors as yourself. I feel that you are knowledgeable on the climate subject. If you say the data is inconclusive (other planets) and therefore cannot be used. I am not convinced. Show me studies that solar system planets have no bearing on Earth climate models, then cite references as proof.--[[User:Jpatt|jpatt]] 22:25, 26 February 2009 (EST)

::I shall try to elaborate on points Robert has already made. We do not have ice core samples from Neptune or Pluto. We don't have fossil data from Mars or Titan. What data we do have is at best a starting point for further analysis. On Earth we have much more data, and we also have the ability to carry out almost any experiment. As Robert said, what data we do have about the climates of other planets is absolutely useless for establishing a model of any kind. It could be that Mars is undergoing a typical cycle of climate change that is unique to its environment. We don't know. It could be that Neptune is warming because more gasses than normal are collapsing to the center of the planet and releasing heat caused by the friction of the particles rubbing against each other as they fall. We don't know. Premises don't spring from nothing, so we can't make an argument out of facts that we don't have.
It is also a bad idea to compare the climates of gas giants with rocky planets: the differences are so extreme that it is hardly worth going over.
I'll end by saying this: If common argument is that we don't really understand the Earth's climate, then how are we to know it any better through comparison of environments that we know almost nothing about? [[User:Jirby|Jirby]] 00:01, 27 February 2009 (EST)
