Evidence Of Glaciers On Mars Suggests Recent Climate Activity

Last year, the Mars Reconnaissance Orbiter captured high-resolution images of the Red Planet which showed many mesas, valleys, and rock debris which appeared to be (geologically speaking) recent formations. A team of scientists from Brown University analyzed the photographs and found evidence that the terrain was carved by large glaciers much more recently than they thought possible. Climate activity on Mars was thought to have quieted over 3 billion years ago, but these glaciers would have been around within the last 10-100 million years. "The finding could have implications for the life-on-Mars argument by strengthening the case for liquid water. Ice can melt two ways: by temperature or by pressure. As currently understood, the Martian climate is dominated by sublimation, the process by which solid substances are transformed directly to vapor. But ice packs can exert such strong pressure at the base to produce liquid water, which makes the thickness of past glaciers on its surface so intriguing."

    This proves the existence of Martians...

    Where was Al Gore when Mars needed him? Guess it is too late to bring back the glaciers now. Damn Martian SUVs!

      Silly. Al Gore wasn't born yet.

      John McCain on the other hand, could have done something but instead accepted the claims of martian corporate lobbyists that evidence for martian climate change was inconclusive.

      Ahhh but don't you see? It was all Al's fault. The Martians listened to him and believed his Powerpoint presentation. So they cut back on green house gases until the planet froze in a perpetual ice age! And now he wants to do it to us! If we cut back on green house gasses, the glaciers will grow and polar bears will migrate south to eat our women and children. We have to stop this environmentalism crap or all we'll all be killed and turned into Bear Chow.

    Let me make the obvious point that this news is in no way an argument against anthropogenic climate change, not in the least because they're talking about events that are MILLIONS OF YEARS OLD. Bull. Everyone smart enough to know that climate change isn't caused by mankind knows that the universe isn't more than a few thousand years old.

    it has to be man made. the sun and natural effects couldn't possibly change the weather! Nope, it was Martian made, and they died out 100 million years ago because of it. Repent, sinners, for you repeat the sins of GOD's first try!
