"non solar components"... are you talking about distance from the sun? Why else would Venus be too hot, and Mars be too cold?

Mars doesn't have any to speak of, Earth has a lot and Venus has loads of it. Combine those type of things with distance to the sun, axis of the planet and planetary rotation and spin and about a Gazillion other things contribute to regulation of the atmosphere.

Did you quote that paragraph from somewhere or do you actually know this stuff - because I have questions?
Here's one... Obviously we feel the affects of the sun down here on the surface of the earth... heat, UV rays, our bodies get Vitamin D, etc... implying that these are things that penetrate the magnetic field above the earth. What is the magnetic or metallic property in the solar winds/storms that subjects them to the earth's magnetic field, so that the magnetic fields attract them towards the earth's poles ?
