Ben, you forgot something.
The warming on Mars is obviously caused by all of the human generated junk we've left on Mars. You know, things like Spirit, Opportunity, Sojourner, Viking 1, Viking 2, and so on. They're kind of like the interplanetary version of SUVs, only more high tech. So the global warming on Mars is All-The-Fault-Of-The-Evil-Humans.......
Can't you see that????
Hadn't thought of that idea ... BRILLIANT!
Have they blamed the Jews and/or Bush yet?
