This paper here goes into some detail about how Mars' experiences its own form of 'ice ages' on a quasi periodic basis driven by the wobbling of its axis. The main mechanism outlined is that the stability of water ice on the surface increases with increased obliquity. Why is this?

On a more discussion based addition to the question, could factors such as ice albedo and other feedback loops play a similar role in Mars' ice ages that they do in Earth's ice ages?

I have also asked this here on the EarthScience stack exchange

As essentially a planetary science question, I'd argue that this would be more on-topic on Space Exploration, but since you already cross-posted (please don't do that, it doubles the effort to clarify the question if that needs to be done and could lead to having to read answers in two places) over at Earth Science where you also IMHO got a good answer, this renders migration pointless. Even more so if Earth Science wanted to migrate it to Space Exploration too, but couldn't because it would create a duplicate on the target site. So, with lack of a better close reason, I'm voting as off topic. –  TildalWave Apr 17 at 0:50

Not sure of what it is you are asking here.The polor caps are formed due to relativity humidity of thin atmosphere at freezing point forming "air Bourne" crystals and fall to the ground.this occurs as "furring" on already frozen twigs and branches here on earth. The furring can also evaporate(dissapear)without turing to water if the air is dry. Earth ice age could be due long term " Sun" orbit which is changing as it revolves around "milky way" but due to the earths rotation(gyroscope effect) could be,say,45deg tilt relative to the change in new sun galaxy orbit.Just a thought,no theory reference.
