    I wonder how the martians are going to tackle this problem.:lol::lol:

    Climate change hits Mars - Times Online

    From The Sunday Times April 29, 2007

    Climate change hits Mars
    Recommend? (22)
    Mars is being hit by rapid climate change and it is happening so fast that the red planet could lose its southern ice cap, writes Jonathan Leake.

    Scientists from Nasa say that Mars has warmed by about 0.5C since the 1970s. This is similar to the warming experienced on Earth over approximately the same period.

    Since there is no known life on Mars it suggests rapid changes in planetary climates could be natural phenomena.

    I wonder what Al Gore has to say about this, maybe if we can find him while he is flying around the world on his private jet, we could ask him. :lol::lol:

    Maybe we should send Al Gore to Mars to have him help the Martians with their global warming problem.LOLOLOLOLOLO

    The reason for this is simple. There is more CO2 in the "air" of Mars than there is in the air of Earth. Obviously, the Greenhouse Effects of CO2 are working even on Mars. At least it is working when the CO2 has not frozen into dry ice.

    The next couple of paragraphs in the story


    The mechanism at work on Mars appears, however, to be different from that on Earth. One of the researchers, Lori Fenton, believes variations in radiation and temperature across the surface of the Red Planet are generating strong winds.

    In a paper published in the journal Nature, she suggests that such winds can stir up giant dust storms, trapping heat and raising the planet’s temperature.

    Fenton’s team unearthed heat maps of the Martian surface from Nasa’s Viking mission in the 1970s and compared them with maps gathered more than two decades later by Mars Global Surveyor. They found there had been widespread changes, with some areas becoming darker.

    When a surface darkens it absorbs more heat, eventually radiating that heat back to warm the thin Martian atmosphere: lighter surfaces have the opposite effect. The temperature differences between the two are thought to be stirring up more winds, and dust, creating a cycle that is warming the planet.

    What about the CO2? Don't they talk about the CO2 at all? There's about twice as much per cubic foot than on Earth. The chemical properties of CO2 must change depending on location.

    I vacationed in Honolulu one year from Minneapolis. It was January. The CO2 in Hawaii was working allot harder out there than it was in Minneapolis. That Minneapolis CO2 is worthless in the winter. The Hawaiin CO2 works great year round.

    yes....that deadly evil CO2.

    They pick the one gas that everything gives off when it burns.

    I think it has more to do with the SUN then CO2 levels....which haven't changed on Mars.

    Have you ever noticed that the air you breathe out is warmer than the air you breathe in?
