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.

    Every we go we seem to fuck up the climate.

    NO, NO, NO - just think about the percentage increase in cars on Mars in the last few years! :-)

    It amazes me how many ppl love to mix truth with lies. It also amazes me that you got modded up for your posting, showing that there are a lot of fox news type ppl here.

    Katrina was accurately predicted. That is why they started evac of NOLA 2 days ahead of time (a none prediction would have waited until it hit). Of course, it was not predicted 4-5 days ahead, but only 2. Just as right now, the prediction is that Rita will hit somewhere in Texas. It may hit NOLA again, but the prediction is that rita will hit at Houston or just south. And that is 4 days out.

    Now, as to global warming; That is also real. That is fact. The fact that glaciers all over the world are shrinking at an unheard of rate is absolute proof. Print not good enough for you? Then there are plenty of pix of glaciers from 100 years ago, that clearly show they were much larger. Google a bit. In fact, the only ice that is growing is Antarctica which the models clearly showed would happen due to increased moisture in the air (it is still DAMN cold there).

    The real issue is not Global Warming (which even your leader has now accepted as happening). The issues are
    1. how is it occurring
    2. are we a major or minor issue with it
    3. How far will it go, if changes are not effected.
    4. And what happens?


    As to stop making predictions based upon ignorance, well, yes, I would very much like that. In fact, it would be nice to not deal with posts made on ignorance as well. My prediction is that neither will occur.
