Haven't past scientific studies also indicated that the ice caps at Mars' poles grow and recede in a natural cycle?

Yes, they are closely tied to sunspot cycles.

I wonder if scientists can correlate that with climate on THIS planet.....

..............nahhhhhhhh

Man, that is the truth. When they do that, the story is buried and ignored anyway.

No waaaayyy. This planet has people. And people drive SUVs. And SUVs contribute ALL the CO and CO₂ there is.
Couldn't possibly be related to sunspots. Sunspots are for planets without people. </sarcasm>
