Mars Orbiter Sees Changes

pin_gween writes "The long-lived Mars Global Surveyor (8 yrs and flying) has enabled scientists to see changes in the surface of Mars. From the article: 'New gullies that did not exist in mid-2002 have appeared on a Martian sand dune. New impact craters formed since the 1970s suggest changes to age-estimating models. And for three Mars summers in a row, deposits of frozen carbon dioxide near Mars' south pole have shrunk from the previous year's size, suggesting a climate change in progress.' The probe's primary mission ended in 2001 and scientists are hopeful the orbiter's life can be extended for another 5 -10 years."

    It would show definite evidence that man is affecting climate change IFF there were factories and automobiles creating the same quantity of greenhouse gasses. That there are neither of these implies "global warming" can happen independently of man.

    It's all those gas guzzling Martian SUVs melting the ice caps. We need to convince them all to switch to Insight and Prius cars and all will be hunky dory. If anyone's going to melt that us, it had better be US, dammit!

    just think about the percentage increase in cars on Mars in the last few years!

    Cars? Have you see the size of those things? They're definitely SUVs! And who was president when they were sent there? George W Bush!
