Mars' Global Warming Simultaneous With Earth's

From National Geographic. As we've previously written, we believe firmly that there are no SUVs on Mars nor are there factories spewing out global warming producing gases. Yet, Mars' increase in temperatures seems to parallel our own pointing directly at the sun as the cause. So repeating an apparent natural cycle that has played out on Earth for Millenia.

Perhaps Al Gore can purchase some carbon credits for Mars and make us all feel better.
