First of all, I'm not claiming to be a climatologist or a scientist of any sort.  I'm just a humble man who looks for the truth.  IN the case of things that are beyond my education I resort to people that actually know what they are talking about.  Like for instance in global warming.


From what I understand, your basic premise is wrong for two reasons.  The first one being that Mars' atmosphere is considerably different than Earth's.  In fact, Earth's atmosphere is incredibly thick compared to Mars'.  Our atmosphere reflects something like 2/3'ds of all the suns radiation away from us.  If mars has little to no atmosphere it would only make sense that it would experience more heat from the sun.


But perhaps the most damaging retort to this Mars argument is that it seems the supposed warming period is actually "based on faulty understanding of the data."

Recently, there have been some suggestions that "global warming" has been observed on Mars (e.g. here). These are based on observations of regional change around the South Polar Cap, but seem to have been extended into a "global" change, and used by some to infer an external common mechanism for global warming on Earth and Mars (e.g. here and here). But this is incorrect reasoning and based on faulty understanding of the data.
