Otherwise, maybe it was a natural cycle, caused by something that's out of our control... After all, I read somewhere that the ice caps on Mars have been seen to be melting, or at least receding... What's the cause of that?
I guess maybe I'm just not educated enough, because I see that a) there's a historical cycle of temperature fluctuations, and b) those fluctuations are occuring on another planet, so I'm just not convinced that anything we do is either causing "global warming," nor can we stop it.
